The United States Army Corps of Engineers, also sometimes shortened to CoE is a U. S. Although generally associated with dams, canals and flood protection in the United States, the Corps of Engineers provides outdoor recreation opportunities to the public, and provides 24% of U. S. hydropower capacity. The corps mission is to Deliver vital public and military engineering services, partnering in peace and war to strengthen our Nations security, energize the economy and their most visible missions include, Planning, designing, building, and operating locks and dams. Other civil engineering projects include flood control, beach nourishment, design and construction of flood protection systems through various federal mandates. Design and construction management of military facilities for the Army, Air Force, Army Reserve and Air Force Reserve and other Defense and Federal agencies. The history of United States Army Corps of Engineers can be traced back to 16 June 1775, colonel Richard Gridley became General George Washingtons first chief engineer, however, it was not until 1779 that Congress created a separate Corps of Engineers. One of its first tasks was to build fortifications near Boston at Bunker Hill, the first Corps of Engineers was mostly composed of French subjects who had been hired by General Washington from the service of Louis XVI. that the said Corps. Shall be stationed at West Point in the State of New York, until 1866, the superintendent of the United States Military Academy was always an officer of engineer. During the first half of the 19th century, West Point was the major and, for a while, the General Survey Act of 1824 authorized the use of Army engineers to survey road and canal routes. Separately authorized on 4 July 1838, the U. S and it was merged with the Corps of Engineers on 31 March 1863, at which point the Corps of Engineers also assumed the Lakes Survey District mission for the Great Lakes. In 1841, Congress created the Lake Survey, the survey, based in Detroit, Mich. was charged with conducting a hydrographical survey of the Northern and Northwestern Lakes and preparing and publishing nautical charts and other navigation aids. The Lake Survey published its first charts in 1852, in the mid-19th century, Corps of Engineers officers ran Lighthouse Districts in tandem with U. S. Naval officers. The Army Corps of Engineers played a significant role in the American Civil War, many of the men who would serve in the top leadership in this institution were West Point graduates who rose to military fame and power during the Civil War. Some of these men were Union Generals George McClellan, Henry Halleck, George Meade, and Confederate generals Robert E. Lee, Joseph Johnston, the versatility of officers in the Army Corps of Engineers contributed to the success of numerous missions throughout the Civil War. They were responsible for building pontoon and railroad bridges, forts and batteries, the destruction of supply lines. The Army Corps of Engineers served as a function in making the war effort logistically feasible. This method of building trenches was known as the zigzag pattern, from the beginning, many politicians wanted the Corps of Engineers to contribute to both military construction and works of a civil nature. During World War II the mission grew to more than 27,000 military, included were aircraft, tank assembly, and ammunition plants, camps for 5.3 million soldiers, depots, ports, and hospitals, as well as the Manhattan Project, and the Pentagon

First United States Army
–
It now serves as a mobilization, readiness and training command. First Army was established on 10 August 1918 as an army when sufficient American military manpower had arrived in France during World War I. As an element of the American Expeditionary Forces in the stages of World War I it was the first of three field armies established under the AEF. Serving in its ranks were many figures who played important roles in World War II. First Army was inactivated in April 1919, the field armies were established to provide organizational structure for large military organizations that might be mobilized in time of national need. First Army was located in the northeast United States and was activated on 11 September 1933 at Fort Jay, Governors Island, initially activated as a paper army, it was commanded by General Dennis E. Nolan. Until 1942, First Armys commander was always the senior commander of one of its three corps areas, since First Army was only a paper organization in its early days, its staff was the existing staff of the corps areas. The overall mission of the First Army was commanding and training army, army reserve. In the years after World War I, Conner was a mentor in the careers of Dwight Eisenhower. Passed over as a candidate for Army Chief of Staff for Douglas MacArthur, in 1938 First Army came under command of General Hugh A. Drum. Drum who along with a buildup of the Army in 1939 and it began to establish and develop its own staff and participated in the large scale Army maneuvers in Louisiana and North Carolina between 1939 and 1941. As the United States entered World War II, Drum was assigned a new command of the newly established Eastern Defense Command, responsible for coastal, Drum retired in 1943 when he reached mandatory retirement age. Headquarters, First Army was activated In January 1944 at Bristol, upon going ashore on 6 June 1944, D-Day, First Army came under 21st Army Group and commanded all American ground forces during the invasion. Three American divisions were landed by sea at the Western end of the beaches, on Utah Beach the assault troops made good time, but Omaha Beach came nearest of all of the five landing areas to disaster. First Army captured much of the gains of the Allied forces in Normandy. Once the beachheads were joined up, its troops struck west and isolated the Cotentin Peninsula, when the American Mulberry harbour was wrecked by a storm, Cherbourg became even more vital. After the capture of Cherbourg, First Army struck south, in Operation Cobra, its forces finally managed to break through the German lines.

Rock Island made the list of the nations 25 Most Affordable Housing Markets and this area has been a fortuitous place first for settlement and then for steamboat traffic, bridges, and railroads. Various Native American tribes occupied this area for thousands of years before settlement, by the early nineteenth century, it was occupied chiefly by the historic Sauk tribe. Their major village of Saukenuk was located on the side of Rock Island. After the War of 1812, the United States built Fort Armstrong on the island for defensive reasons in 1816, Saukenuk was the birthplace of the Sauk war chief Black Hawk, for whom the Black Hawk War of 1831–1832 was named. Fort Armstrong served as the US militarys headquarters for the war, today the Black Hawk State Historic Site, listed on the National Register of Historic Places, includes much of the site of the original village of Saukenuk. The park includes a museum and a number of hiking trails along the Rock River, the Chicago, Rock Island & Pacific Railroad was founded here in 1851. It was informally known as the Rock Island Line, as part of later nineteenth-century development, two first-class hotels, the Harper House and the Rock Island House were built in town. Rock Island Arsenal has manufactured military equipment and ordnance for the U. S. Army since the 1880s, the railroad was liquidated in bankruptcy in 1980. The first railroad bridge across the Mississippi River was built between Arsenal Island and Davenport in 1856, two weeks after the bridge opened, the steamboat Effie Afton collided with the bridge, caught fire, and damaged the bridge. The owner of the Effie Afton sued the company for damages. This test case was appealed to the United States Supreme Court, although the original bridge is long gone, a monument exists on Arsenal Island marking the Illinois side

Arsenal
–
An arsenal is a place where arms and ammunition are made, maintained and repaired, stored, or issued, in any combination, whether privately or publicly owned. Arsenal and armoury or armory are mostly regarded as synonyms, although differences in usage exist. A sub-armory is a place of storage or carrying of weapons and ammunition. From Italian, arsenale, and French, arsenal, from Arabic, دار تعبئة, dār a-tabiya, in a second-class arsenal, the factories would be replaced by workshops. The situation of an arsenal should be governed by strategic considerations. If of the first class, it should be situated at the base of operations and supply, secure from attack, not too near a frontier, the importance of a large arsenal is such that its defences would be on the scale of those of a large fortress. The usual subdivision of branches in a great arsenal is into storekeeping, under construction, Gun factory, carriage factory, laboratory, small-arms factory, harness and tent factory, powder factory, etc. In a second-class arsenal there would be instead of these factories. Frederick Taylor introduced command and control techniques to arsenals, including the U. S. s Watertown Arsenal, armorer Dresden Armory Halifax Armoury Harpers Ferry Armory Kremlin Armoury Royal Arsenal Royal Armouries Springfield Armory Zeughaus Magazine

Black Hawk War
–
The Black Hawk War was a brief 1832 conflict between the United States and Native Americans led by Black Hawk, a Sauk leader. Black Hawks motives were ambiguous, but he was hoping to avoid bloodshed while resettling on tribal land that had been ceded to the United States in the disputed 1804 Treaty of St. Louis. US officials, convinced that the British Band was hostile, mobilized a frontier militia, Black Hawk responded by successfully attacking the militia at the Battle of Stillmans Run. He led his band to a location in what is now southern Wisconsin and was pursued by US forces. Meanwhile, other Native Americans conducted raids against forts and settlements largely unprotected with the absence of US troops, some Ho-Chunk and Potawatomi warriors with grievances against European-Americans took part in these raids, although most tribe members tried to avoid the conflict. The Menominee and Dakota tribes, already at odds with the Sauks and Meskwakis, commanded by General Henry Atkinson, the US troops tracked the British Band. Militia under Colonel Henry Dodge caught up with the British Band on July 21, Black Hawks band was weakened by hunger, death, and desertion and many native survivors retreated towards the Mississippi. On August 2, US soldiers attacked the remnants of the British Band at the Battle of Bad Axe, Black Hawk and other leaders escaped, but later surrendered and were imprisoned for a year. The Black Hawk War gave the young captain Abraham Lincoln his brief military service, other participants who later became famous included Winfield Scott, Zachary Taylor, and Jefferson Davis. The war gave impetus to the US policy of Indian removal, in which Native American tribes were pressured to sell their lands and move west of the Mississippi River and stay there. In the 18th century, the Sauk and Meskwaki Native American tribes lived along the Mississippi River in what is now the U. S. states of Illinois, by the time of the Black Hawk War, the population of the two tribes was about 6,000 people. As the United States expanded westward in the early 19th century, the treaty became controversial because the Native leaders had not been authorized by their tribal councils to cede lands. Historian Robert Owens argued that the chiefs probably did not intend to give up ownership of the land, and that they would not have sold so much valuable territory for such a modest price. Historian Patrick Jung concluded that the Sauk and Meskwaki chiefs intended to cede a little land, according to Jung, the Sauks and Meskwakis did not learn the true extent of the cession until years later. The 1804 treaty allowed the tribes to continue using the land until it was sold to American settlers by the U. S. government. For the next two decades, Sauks continued to live at Saukenuk, their village, which was located near the confluence of the Mississippi. In 1828, the U. S. government finally began to have the land surveyed for white settlement. Indian agent Thomas Forsyth informed the Sauks that they should vacate Saukenuk, the Sauks were divided about whether to resist implementation of the disputed 1804 treaty

United States Army
–
The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, from the time of its inception, the military played a decisive role in the history of the United States. A sense of unity and identity was forged as a result of victory in the First Barbary War. Even so, the Founders were suspicious of a permanent military force and it played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold Wars onset, the U. S. military is one of the largest militaries in terms of number of personnel. It draws its personnel from a pool of paid volunteers. As of 2016, the United States spends about $580.3 billion annually to fund its military forces, put together, the United States constitutes roughly 40 percent of the worlds military expenditures. For the period 2010–14, the Stockholm International Peace Research Institute found that the United States was the worlds largest exporter of major arms, the United States was also the worlds eighth largest importer of major weapons for the same period. The history of the U. S. military dates to 1775 and these forces demobilized in 1784 after the Treaty of Paris ended the War for Independence. All three services trace their origins to the founding of the Continental Army, the Continental Navy, the United States President is the U. S. militarys commander-in-chief. Rising tensions at various times with Britain and France and the ensuing Quasi-War and War of 1812 quickened the development of the U. S. Navy, the reserve branches formed a military strategic reserve during the Cold War, to be called into service in case of war. Time magazines Mark Thompson has suggested that with the War on Terror, Command over the armed forces is established in the United States Constitution. The sole power of command is vested in the President by Article II as Commander-in-Chief, the Constitution also allows for the creation of executive Departments headed principal officers whose opinion the President can require. This allowance in the Constitution formed the basis for creation of the Department of Defense in 1947 by the National Security Act, the Defense Department is headed by the Secretary of Defense, who is a civilian and member of the Cabinet. The Defense Secretary is second in the chain of command, just below the President. Together, the President and the Secretary of Defense comprise the National Command Authority, to coordinate military strategy with political affairs, the President has a National Security Council headed by the National Security Advisor. The collective body has only power to the President

Fort Armstrong, Illinois
–
Fort Armstrong, was one of a chain of western frontier defenses which the United States erected after the War of 1812. It was located at the foot of Rock Island, Illinois, in the Mississippi River near the present-day Quad Cities of Illinois and it was five miles from the principal Sac and Fox village on Rock River in Illinois. Of stone and timber construction,300 feet square, the fort was begun in May 1816, in 1832, the U. S. Army used the fort, as a military headquarters, during the Black Hawk War. It was normally garrisoned by two companies, of United States Army regulars, with the pacification of the Indian threat in Illinois, the U. S. Government ceased operations at Fort Armstrong and the U. S. Army abandoned the frontier fort in 1836. Pike identified one site as the big island, Congress agreed with his recommendation, reserving the island for use in 1809. The Sauk considered the sacred, This was the best one on the Mississippi. It was our garden, like the people have near their big villages. Being situated at the foot of the rapids, its waters supplied us with the finest fish, in my early life I spent many happy days on this island. A good spirit had charge of it, which lived in a cave in the rocks immediately under the place where the now stands. This guardian spirit has often seen by our people. It was white, with wings like a swans. We were particular not to make noise in that part of the island which it inhabited. But the noise at the fort has since driven it away, -Black Hawk This was to be the second US fort between St. Louis and Prairie du Chien, Wisconsin. The US wanted to establish a presence to dissuade the French. After its losses at several forts during the War of 1812, the fort also would serve to protect American settlers within the area and to help control or remove the Sauk, the American Indians in the region. The Sauk disapproved of its construction, Black Hawk wrote in his memoir and this, in our opinion, was a contradiction to what we had done– to prepare for war in time of peace. We did not object, however, to their building their fort on the island, on May 10,1816, soldiers arrived to begin construction of Fort Armstrong. It was named after John Armstrong, the Secretary of War under President James Madison, the army assigned 600 soldiers and 150 laborers to the project

National Register of Historic Places
–
The National Register of Historic Places is the United States federal governments official list of districts, sites, buildings, structures, and objects deemed worthy of preservation. The passage of the National Historic Preservation Act in 1966 established the National Register, of the more than one million properties on the National Register,80,000 are listed individually. The remainder are contributing resources within historic districts, each year approximately 30,000 properties are added to the National Register as part of districts or by individual listings. For most of its history the National Register has been administered by the National Park Service and its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, coordinate, identify, and protect historic sites in the United States. While National Register listings are mostly symbolic, their recognition of significance provides some financial incentive to owners of listed properties, protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places, the application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. Occasionally, historic sites outside the proper, but associated with the United States are also listed. Properties can be nominated in a variety of forms, including individual properties, historic districts, the Register categorizes general listings into one of five types of properties, district, site, structure, building, or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties, some properties are added automatically to the National Register when they become administered by the National Park Service. These include National Historic Landmarks, National Historic Sites, National Historical Parks, National Military Parks/Battlefields, National Memorials, on October 15,1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices. Initially, the National Register consisted of the National Historic Landmarks designated before the Registers creation, approval of the act, which was amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy. To administer the newly created National Register of Historic Places, the National Park Service of the U. S. Department of the Interior, hartzog, Jr. established an administrative division named the Office of Archeology and Historic Preservation. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law, ernest Connally was the Offices first director. Within OAHP new divisions were created to deal with the National Register, the first official Keeper of the Register was William J. Murtagh, an architectural historian. During the Registers earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small, understaffed, and underfunded. A few years later in 1979, the NPS history programs affiliated with both the U. S. National Parks system and the National Register were categorized formally into two Assistant Directorates. Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation, from 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs, jerry L. Rogers was selected to direct this newly merged associate directorate

National Historic Landmark
–
A National Historic Landmark is a building, district, object, site, or structure that is officially recognized by the United States government for its outstanding historical significance. Of over 85,000 places listed on the countrys National Register of Historic Places, a National Historic Landmark District may include contributing properties that are buildings, structures, sites or objects, and it may include non-contributing properties. Contributing properties may or may not also be separately listed, prior to 1935, efforts to preserve cultural heritage of national importance were made by piecemeal efforts of the United States Congress. The first National Historic Site designation was made for the Salem Maritime National Historic Site on March 17,1938. In 1960, the National Park Service took on the administration of the data gathered under this legislation. Because listings often triggered local preservation laws, legislation in 1980 amended the procedures to require owner agreement to the designations. On October 9,1960,92 properties were announced as designated NHLs by Secretary of the Interior Fred A. Seaton, more than 2,500 NHLs have been designated. Most, but not all, are in the United States, there are NHLs in all 50 states and the District of Columbia. Three states account for nearly 25 percent of the nations NHLs, three cities within these states all separately have more NHLs than 40 of the 50 states. In fact, New York City alone has more NHLs than all but five states, Virginia, California, Pennsylvania, Massachusetts, there are 74 NHLs in the District of Columbia. Some NHLs are in U. S. commonwealths and territories, associated states, and foreign states. There are 15 in Puerto Rico, the Virgin Islands, and other U. S. commonwealths and territories,5 in U. S. -associated states such as Micronesia, over 100 ships or shipwrecks have been designated as NHLs. About half of the National Historic Landmarks are privately owned, the National Historic Landmarks Program relies on suggestions for new designations from the National Park Service, which also assists in maintaining the landmarks. A friends group of owners and managers, the National Historic Landmark Stewards Association, works to preserve, protect, if not already listed on the National Register of Historic Places, an NHL is automatically added to the Register upon designation. About three percent of Register listings are NHLs, american Water Landmark List of U. S

Quarters 1 (Rock Island)
–
Quarters One is the residence of the highest-ranking officer on the Rock Island Arsenal in Rock Island, Illinois on the banks of the Mississippi River. At 51 rooms and 21,965 square feet, Quarters One is the second-largest federal residence in the United States, work begun on Quarters One by General Thomas S. Rodman in 1870 and was completed in 1872 by Major Flagler. The home was built for the purpose of providing quarters for the officer as well as providing space for official gatherings. The building was designed in the Italianate style, the first major gathering held in the residence was in 1871 for the funeral of General Rodman. Over the years, many dignitaries and notable personalities stayed at the residence including Charles Lindbergh in 1927 and King Carl XVI Gustav, in 2006, the Army decided to discontinue its use as a residence. Tours are offered occasionally, and the Army is currently exploring other uses for the building

Geographic coordinate system
–
A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are chosen such that one of the numbers represents a vertical position. A common choice of coordinates is latitude, longitude and elevation, to specify a location on a two-dimensional map requires a map projection. The invention of a coordinate system is generally credited to Eratosthenes of Cyrene. Ptolemy credited him with the adoption of longitude and latitude. Ptolemys 2nd-century Geography used the prime meridian but measured latitude from the equator instead. Mathematical cartography resumed in Europe following Maximus Planudes recovery of Ptolemys text a little before 1300, in 1884, the United States hosted the International Meridian Conference, attended by representatives from twenty-five nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, the Dominican Republic voted against the motion, while France and Brazil abstained. France adopted Greenwich Mean Time in place of local determinations by the Paris Observatory in 1911, the latitude of a point on Earths surface is the angle between the equatorial plane and the straight line that passes through that point and through the center of the Earth. Lines joining points of the same latitude trace circles on the surface of Earth called parallels, as they are parallel to the equator, the north pole is 90° N, the south pole is 90° S. The 0° parallel of latitude is designated the equator, the plane of all geographic coordinate systems. The equator divides the globe into Northern and Southern Hemispheres, the longitude of a point on Earths surface is the angle east or west of a reference meridian to another meridian that passes through that point. All meridians are halves of great ellipses, which converge at the north and south poles, the prime meridian determines the proper Eastern and Western Hemispheres, although maps often divide these hemispheres further west in order to keep the Old World on a single side. The antipodal meridian of Greenwich is both 180°W and 180°E, the combination of these two components specifies the position of any location on the surface of Earth, without consideration of altitude or depth. The grid formed by lines of latitude and longitude is known as a graticule, the origin/zero point of this system is located in the Gulf of Guinea about 625 km south of Tema, Ghana. To completely specify a location of a feature on, in, or above Earth. Earth is not a sphere, but a shape approximating a biaxial ellipsoid. It is nearly spherical, but has an equatorial bulge making the radius at the equator about 0. 3% larger than the radius measured through the poles, the shorter axis approximately coincides with the axis of rotation

Thomas Jackson Rodman
–
Thomas Jackson Rodman was an American artillerist, inventor, ordnance specialist, and career United States Army officer. He served as a Union Army general during the American Civil War, in which he was noted for his many improvements and innovations concerning the artillery used by the Union forces. He is especially remembered for developing the Rodman gun, which in various sizes saw extensive use in coastal defenses and this resulted in increased muzzle velocities with lower maximum pressures when compared to performance with conventional ball powder. The Rodman seven perforation grain was named after Rodman, and similar propellant grain shapes are still in use today in artillery, rockets, and automotive airbag inflators. After the conflict Rodman remained with the U. S. Army in his chosen profession, thomas Jackson Rodman was born in 1816 on a farm near Salem in Washington County, Indiana. He was a son of James Rodman and his wife Elizabeth Burton, in 1837 Rodman entered the United States Military Academy in West Point, and graduated four years later, standing seventh out of 52 cadets. On July 1,1841, He was appointed a second lieutenant in the U. S. Army Ordnance Department. On December 13,1843, Rodman married Martha Ann Black, and his two daughters were named Florence and Ella Elizabeth, and his sons were named, John B. Thomas Jackson Jr. Robert S. and Addison B, two of Rodmans sons also attended West Point. Addison Burton Rodman was admitted on July 1,1877, John Black Rodman was admitted on September 1,1863, graduated on June 15,1868, served initially with the 20th U. S. Infantry, and rose to the rank of colonel before retiring. Rodman also saw limited action in 1846–48 during the Mexican–American War. Starting in 1844, Rodman began running experiments to overcome the limitations of cast iron cannon due to the way they were made. Up to that time, all cannon barrels made of iron were cast solid and then cooled only on their outside, made in this way, the cannons could crack during the cooling process, break apart during shipment, or worse burst as they were fired. Although it took him years, Rodman developed a way to solve these drawbacks and he found that if he cast the iron around a hollow core and then applied a steady stream of water within the barrel for cooling, a much more reliable and stronger product was made. His method, and the result, has described as. Rodmans manufacturing method, now known as the wet chill process, doing this forced the thickest material toward the center of the barrel, and Rodman would then patent this invention. On March 3,1847, Rodman was promoted to first lieutenant, Rodman experimented for almost a decade at the Fort Pitt Foundry in Pittsburgh, Pennsylvania, testing his theory and performing trial runs of his cannon barrels. After viewing the results, the U. S, War Department approved construction of a fifteen-inch smoothbore columbiad of Rodmans design in 1859

Greek Revival architecture
–
The Greek Revival was an architectural movement of the late 18th and early 19th centuries, predominantly in Northern Europe and the United States. A product of Hellenism, it may be looked upon as the last phase in the development of Neoclassical architecture, the term was first used by Charles Robert Cockerell in a lecture he gave as Professor of Architecture to the Royal Academy of Arts, London in 1842. With a newfound access to Greece, or initially the books produced by the few who had actually been able to visit the sites, archaeologist-architects of the period studied the Doric and Ionic orders. This was especially the case in Britain, Germany and the United States, Greek Revival architecture took a different course in a number of countries, lasting until the Civil War in America and even later in Scotland. Despite the unbounded prestige of ancient Greece amongst the elite of Europe. The monuments of Greek antiquity were known chiefly from Pausanias and other literary sources, visiting Ottoman Greece was difficult and dangerous business prior to the period of stagnation beginning with the Great Turkish War. Few Grand Tourists called on Athens during the first half of the 18th century and it would take until the expedition funded by the Society of Dilettanti of 1751 by James Stuart and Nicholas Revett before serious archaeological inquiry began in earnest. Access to the originals in Greece itself only became easier after the Greek War of Independence ended in 1832, Lord Byrons participation, following James Stuarts travels to Greece in the early 1750s, intellectual curiosity quickly led to a desire to emulate. Stuart was commissioned after his return from Greece by George Lyttelton to produce the first Greek building in England, arguably the greatest British exponent of the style was Decimus Burton. In London twenty three Greek Revival Commissioners churches were built between 1817 and 1829, the most notable being St. Pancras church by William and Henry William Inwood. Such was the popularity of the Doric in Edinburgh that the city now enjoys a striking visual uniformity, nevertheless, Greek continued to be in favour in Scotland well into the 1870s in the singular figure of Alexander Thomson, known as Greek Thomson. In Germany, the Greek revival is predominantly found in two centres, Berlin and Munich, the earliest Greek building was the Brandenburg Gate by Carl Gotthard Langhans, who modelled it on the Propylaea. Ten years after the death of Frederick the Great, the Berlin Akademie initiated a competition for a monument to the king that would promote morality, similarly, in Munich von Klenzes Glyptothek and Walhalla were the fulfilment of Gillys vision of an orderly and moral German world. The purity and seriousness of the style was intended as an assertion of German national values and partly intended as a riposte to France. By comparison, the Greek revival in France was never popular with either the state or the public, what little there is started with Charles de Waillys crypt in the church of St Leu-St Gilles, and Claude Nicolas Ledouxs Barriere des Bonshommes. It would take until Laboustres Neo-Grec of the Second Empire for the Greek revival to flower briefly in France, the style was especially attractive in Russia, if only because they shared the Eastern Orthodox faith with the Greeks. The historic centre of Saint Petersburg was rebuilt by Alexander I of Russia, the Saint Petersburg Bourse on Vasilievsky Island has a temple front with 44 Doric columns. Leo von Klenzes expansion of the palace that is now the Hermitage Museum is another example of the style, following the Greek War of Independence, Romantic Nationalist ideology encouraged the use of historically Greek architectural styles in place of Ottoman or pan-European ones

American Civil War prison camps
–
American Civil War Prison Camps were operated by both the Union and the Confederacy to handle the 409,000 soldiers captured during the war, 1861–1865. The Record and Pension Office in 1901 counted 211,000 Northerners who were captured, in 1861-63 most were immediately paroled, after the parole exchange system broke down in 1863, about 195,000 went to prison camps. Some tried to escape but few succeeded, by contrast 464,000 Confederates were captured and 215,000 imprisoned. Over 30,000 Union and nearly 26,000 Confederate prisoners died in captivity, just over 12% of the captives in Northern prisons died, compared to 15. 5% for Southern prisons. A prisoner who was on parole promised not to again until his name was exchanged for a similar man on the other side. Then both of them could rejoin their units, while awaiting exchange, prisoners were briefly confined to permanent camps. The exchange system broke down in mid 1863 when the Confederacy refused to treat captured black prisoners as equal to white prisoners, the prison populations on both sides then soared. There were 32 major Confederate prisons,16 of them in the Deep South states of Georgia, Alabama, training camps were often turned into prisons, and new prisons also had to be made. The North had a larger population than the South, and Gen. Ulysses S. Grant was well aware that keeping its soldiers in Northern prisons hurt the Southern economy. At the outbreak of the War, the Federal government avoided any action, including prisoner exchanges, public opinion forced a changed after the First Battle of Bull Run, when the Confederates captured over one thousand Union soldiers. Union and Confederate forces exchanged prisoners sporadically, often as an act of humanity between opposing commanders, support for prisoner exchanges grew throughout the initial months of the war, as the North saw increasing numbers of its soldiers captured. Petitions from prisoners in the South and editorials in Northern newspapers brought pressure on the Lincoln administration, on December 11,1861, the US Congress passed a joint resolution calling on President Lincoln to inaugurate systematic measures for the exchange of prisoners in the present rebellion. In two meetings on February 23 and March 1,1862, Union Major Gen. John E. Wool and they discussed many of the provisions later adopted in the Dix-Hill agreement. However, differences over which side would cover expenses for prisoner transportation stymied the negotiations, Prison camps were largely empty in mid-1862, thanks to the informal exchanges. Both sides agreed to formalize the system, negotiations resumed in July,1862, when Union Maj. Gen. John A. Dix and Confederate Maj. Gen. D. H. Hill were assigned the task. The agreement established a scale of equivalents for the exchange of military officers, thus a navy captain or an army colonel was worth fifteen privates or ordinary seamen, while personnel of equal ranks were exchanged man for man. Each government appointed an agent to handle the exchange and parole of prisoners, authorities were to parole any prisoners not formally exchanged within ten days following their capture. The terms of the cartel prohibited paroled prisoners from returning to the military in any capacity including the performance of field, garrison, police, or guard, the exchange system collapsed in 1863 because the Confederacy refused to treat black prisoners the same as whites

Union (American Civil War)
–
The Union was opposed by 11 southern slave states that formed the Confederate States, or the Confederacy. All of the Unions states provided soldiers for the U. S. Army, the Border states played a major role as a supply base for the Union invasion of the Confederacy. The Northeast provided the resources for a mechanized war producing large quantities of munitions and supplies. The Midwest provided soldiers, food, horses, financial support, Army hospitals were set up across the Union. Most states had Republican governors who energetically supported the war effort, the Democratic Party strongly supported the war in 1861 but in 1862 was split between the War Democrats and the anti-war element led by the Copperheads. The Democrats made major gains in 1862 in state elections. They lost ground in 1863, especially in Ohio, in 1864 the Republicans campaigned under the National Union Party banner, which attracted many War Democrats and soldiers and scored a landslide victory for Lincoln and his entire ticket. The war years were quite prosperous except where serious fighting and guerrilla warfare took place along the southern border, prosperity was stimulated by heavy government spending and the creation of an entirely new national banking system. The Union states invested a great deal of money and effort in organizing psychological and social support for soldiers wives, widows, orphans, and for the soldiers themselves. Most soldiers were volunteers, although after 1862 many volunteered to escape the draft, Draft resistance was notable in some larger cities, especially New York City with its massive anti-draft riots of 1863 and in some remote districts such as the coal mining areas of Pennsylvania. In the context of the American Civil War, the Union is sometimes referred to as the North, both then and now, as opposed to the Confederacy, which was the South. The Union never recognized the legitimacy of the Confederacys secession and maintained at all times that it remained entirely a part of the United States of America, in foreign affairs the Union was the only side recognized by all other nations, none of which officially recognized the Confederate government. The term Union occurs in the first governing document of the United States, the subsequent Constitution of 1787 was issued and ratified in the name not of the states, but of We the People of the United States, in Order to form a more perfect Union. Union, for the United States of America, is repeated in such clauses as the Admission to the Union clause in Article IV. Even before the war started, the preserve the Union was commonplace. Using the term Union to apply to the non-secessionist side carried a connotation of legitimacy as the continuation of the political entity. In comparison to the Confederacy, the Union had a large industrialized and urbanized area, additionally, the Union states had a manpower advantage of 5 to 2 at the start of the war. Year by year, the Confederacy shrank and lost control of increasing quantities of resources, meanwhile, the Union turned its growing potential advantage into a much stronger military force

American Civil War
–
The American Civil War was an internal conflict fought in the United States from 1861 to 1865. The Union faced secessionists in eleven Southern states grouped together as the Confederate States of America, the Union won the war, which remains the bloodiest in U. S. history. Among the 34 U. S. states in February 1861, War broke out in April 1861 when Confederates attacked the U. S. fortress of Fort Sumter. The Confederacy grew to eleven states, it claimed two more states, the Indian Territory, and the southern portions of the western territories of Arizona. The Confederacy was never recognized by the United States government nor by any foreign country. The states that remained loyal, including border states where slavery was legal, were known as the Union or the North, the war ended with the surrender of all the Confederate armies and the dissolution of the Confederate government in the spring of 1865. The war had its origin in the issue of slavery. The Confederacy collapsed and 4 million slaves were freed, but before his inauguration, seven slave states with cotton-based economies formed the Confederacy. The first six to declare secession had the highest proportions of slaves in their populations, the first seven with state legislatures to resolve for secession included split majorities for unionists Douglas and Bell in Georgia with 51% and Louisiana with 55%. Alabama had voted 46% for those unionists, Mississippi with 40%, Florida with 38%, Texas with 25%, of these, only Texas held a referendum on secession. Eight remaining slave states continued to reject calls for secession, outgoing Democratic President James Buchanan and the incoming Republicans rejected secession as illegal. Lincolns March 4,1861 inaugural address declared that his administration would not initiate a civil war, speaking directly to the Southern States, he reaffirmed, I have no purpose, directly or indirectly to interfere with the institution of slavery in the United States where it exists. I believe I have no right to do so, and I have no inclination to do so. After Confederate forces seized numerous federal forts within territory claimed by the Confederacy, efforts at compromise failed, the Confederates assumed that European countries were so dependent on King Cotton that they would intervene, but none did, and none recognized the new Confederate States of America. Hostilities began on April 12,1861, when Confederate forces fired upon Fort Sumter, while in the Western Theater the Union made significant permanent gains, in the Eastern Theater, the battle was inconclusive in 1861–62. The autumn 1862 Confederate campaigns into Maryland and Kentucky failed, dissuading British intervention, Lincoln issued the Emancipation Proclamation, which made ending slavery a war goal. To the west, by summer 1862 the Union destroyed the Confederate river navy, then much of their western armies, the 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River. In 1863, Robert E. Lees Confederate incursion north ended at the Battle of Gettysburg, Western successes led to Ulysses S. Grants command of all Union armies in 1864

Federal government of the United States
–
The Federal Government of the United States is the national government of the United States, a republic in North America, composed of 50 states, one district, Washington, D. C. and several territories. The federal government is composed of three branches, legislative, executive, and judicial, whose powers are vested by the U. S. Constitution in the Congress, the President, and the courts, including the Supreme Court. The powers and duties of these branches are defined by acts of Congress. The full name of the republic is United States of America, no other name appears in the Constitution, and this is the name that appears on money, in treaties, and in legal cases to which it is a party. The terms Government of the United States of America or United States Government are often used in documents to represent the federal government as distinct from the states collectively. In casual conversation or writing, the term Federal Government is often used, the terms Federal and National in government agency or program names generally indicate affiliation with the federal government. Because the seat of government is in Washington, D. C, Washington is commonly used as a metonym for the federal government. The outline of the government of the United States is laid out in the Constitution, the government was formed in 1789, making the United States one of the worlds first, if not the first, modern national constitutional republics. The United States government is based on the principles of federalism and republicanism, some make the case for expansive federal powers while others argue for a more limited role for the central government in relation to individuals, the states or other recognized entities. For example, while the legislative has the power to create law, the President nominates judges to the nations highest judiciary authority, but those nominees must be approved by Congress. The Supreme Court, in its turn, has the power to invalidate as unconstitutional any law passed by the Congress and these and other examples are examined in more detail in the text below. The United States Congress is the branch of the federal government. It is bicameral, comprising the House of Representatives and the Senate, the House currently consists of 435 voting members, each of whom represents a congressional district. The number of each state has in the House is based on each states population as determined in the most recent United States Census. All 435 representatives serve a two-year term, each state receives a minimum of one representative in the House. There is no limit on the number of terms a representative may serve, in addition to the 435 voting members, there are six non-voting members, consisting of five delegates and one resident commissioner. In contrast, the Senate is made up of two senators from each state, regardless of population, there are currently 100 senators, who each serve six-year terms

Union Army
–
The Union Army was the land force that fought for the Union during the American Civil War,1861 to 1865. It included the permanent regular army of the United States, which was augmented by numbers of temporary units consisting of volunteers as well as conscripts. The Union Army fought and eventually defeated the Confederate Army during the war, at least two and a half million men served in the Union Army, almost all were volunteers. About 360,000 Union soldiers died from all causes,280,000 were wounded and 200,000 deserted. When the American Civil War began in April 1861, there were only 16,000 men in the U. S. Army, and of these many Southern officers resigned and joined the Confederate army. The U. S. Army consisted of ten regiments of infantry, four of artillery, Lincolns call forced the border states to choose sides, and four seceded, making the Confederacy eleven states strong. The war proved to be longer and more extensive than anyone North or South had expected, the call for volunteers initially was easily met by patriotic Northerners, abolitionists, and even immigrants who enlisted for a steady income and meals. Over 10,000 Germans in New York and Pennsylvania immediately responded to Lincolns call, as more men were needed, however, the number of volunteers fell and both money bounties and forced conscription had to be turned to. Nevertheless, between April 1861 and April 1865, at least two and a million men served in the Union Army, of whom the majority were volunteers. It is a misconception that the South held an advantage because of the percentage of professional officers who resigned to join the Confederate army. At the start of the war, there were 824 graduates of the U. S, Military Academy on the active list, of these,296 resigned or were dismissed, and 184 of those became Confederate officers. Of the approximately 900 West Point graduates who were civilians,400 returned to the Union Army and 99 to the Confederate. Therefore, the ratio of Union to Confederate professional officers was 642 to 283, the South did have the advantage of other military colleges, such as The Citadel and Virginia Military Institute, but they produced fewer officers. The Union Army was composed of numerous organizations, which were generally organized geographically, Military Division A collection of Departments reporting to one commander. Military Divisions were similar to the modern term Theater, and were modeled close to, though not synonymous with. Department An organization that covered a region, including responsibilities for the Federal installations therein. Those named for states usually referred to Southern states that had been occupied and it was more common to name departments for rivers or regions. District A subdivision of a Department, there were also Subdistricts for smaller regions

Mississippi River
–
The Mississippi River is the chief river of the largest drainage system on the North American continent. Flowing entirely in the United States, it rises in northern Minnesota, with its many tributaries, the Mississippis watershed drains all or parts of 31 U. S. states and 2 Canadian provinces between the Rocky and Appalachian Mountains. The Mississippi ranks as the fourth longest and fifteenth largest river in the world by discharge, the river either borders or passes through the states of Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana. Native Americans long lived along the Mississippi River and its tributaries, most were hunter-gatherers, but some, such as the Mound Builders, formed prolific agricultural societies. The arrival of Europeans in the 16th century changed the way of life as first explorers, then settlers. The river served first as a barrier, forming borders for New Spain, New France, and the early United States, and then as a vital transportation artery and communications link. Formed from thick layers of the silt deposits, the Mississippi embayment is one of the most fertile agricultural regions of the country. In recent years, the river has shown a shift towards the Atchafalaya River channel in the Delta. The word itself comes from Messipi, the French rendering of the Anishinaabe name for the river, see below in the History section for additional information. In addition to historical traditions shown by names, there are at least two measures of a rivers identity, one being the largest branch, and the other being the longest branch. Using the largest-branch criterion, the Ohio would be the branch of the Lower Mississippi. Using the longest-branch criterion, the Middle Mississippi-Missouri-Jefferson-Beaverhead-Red Rock-Hellroaring Creek River would be the main branch and its length of at least 3,745 mi is exceeded only by the Nile, the Amazon, and perhaps the Yangtze River among the longest rivers in the world. The source of this waterway is at Browers Spring,8,800 feet above sea level in southwestern Montana and this is exemplified by the Gateway Arch in St. Louis and the phrase Trans-Mississippi as used in the name of the Trans-Mississippi Exposition. It is common to qualify a regionally superlative landmark in relation to it, the New Madrid Seismic Zone along the river is also noteworthy. These various basic geographical aspects of the river in turn underlie its human history and present uses of the waterway, the Upper Mississippi runs from its headwaters to its confluence with the Missouri River at St. Louis, Missouri. The source of the Upper Mississippi branch is traditionally accepted as Lake Itasca,1,475 feet above sea level in Itasca State Park in Clearwater County, however, the lake is in turn fed by a number of smaller streams. From its origin at Lake Itasca to St. Louis, Missouri, fourteen of these dams are located above Minneapolis in the headwaters region and serve multiple purposes, including power generation and recreation. The remaining 29 dams, beginning in downtown Minneapolis, all locks and were constructed to improve commercial navigation of the upper river

Davenport, Iowa
–
Davenport was founded on May 14,1836 by Antoine Le Claire and was named for his friend, George Davenport, a colonel during the Black Hawk War stationed at nearby Fort Armstrong. According to the 2010 census, the city had a population of 99,685, located approximately halfway between Chicago and Des Moines, Davenport is on the border of Iowa and Illinois. The city is prone to frequent flooding due to its location on the Mississippi River, there are two main universities, Saint Ambrose University and Palmer College of Chiropractic, which is where the first chiropractic adjustment took place. Several annual music festivals take place in Davenport, including the Mississippi Valley Blues Festival, The Mississippi Valley Fair, an internationally known 7-mile foot race called the Bix 7 is run during the festival. The city has a Class A minor league team, the Quad Cities River Bandits. Davenport has 50 plus parks and facilities, as well as over 20 miles of paths for biking or walking. Four interstates and two major United States Highways serve the city, Davenport has seen steady population growth since its incorporation, with an exception being the 1980s, when the population decreased due to job loss. The Quad Cities was ranked as the most affordable metropolitan area in 2010 by Forbes, in 2007, Davenport, along with neighboring Rock Island, won the City Livability Award in the small-city category from the U. S. In 2012, Davenport as well as the Quad Cities Metropolitan Area was ranked among the areas in the nation in the growth of high-tech jobs. The current mayor of Davenport is Frank Klipsch, the land was originally owned by the Sauk people, Meskwaki, and Ho-Chunk – indigenous peoples of the Americas. In 1803 France sold it to the United States under the Louisiana Purchase, lieutenant Zebulon Pike was the first United States representative to officially visit the Upper Mississippi River area. On August 27,1805, Pike camped on the present day site of Davenport, in 1832, a group of Sauk, Meskwaki, and Kickapoo people were defeated by the United States in the Black Hawk War. The United States government then concluded the Black Hawk Purchase, sometimes called the Forty-Mile Strip or Scotts Purchase, the purchase was made for $640,000 on September 21,1832 and contained an area of some 6 million acres, at a price equivalent to 11 cents/acre. Although named after the defeated chief Black Hawk, he was being held prisoner at the time, the purchase was therefore agreed to by Sauk chief Keokuk, who had remained neutral in the war. It was made on the site of present-day Davenport, army General Winfield Scott and Governor of Illinois, John Reynolds, acted on behalf of the United States, with the future Davenport founder, half-Native, Antoine Le Claire serving as translator. Chief Keokuk gave a portion of land to Antoine Le Claires wife, Marguerite. Antoine built their home on the spot where the agreement was signed. Antoine did so, finishing the Treaty House in the spring of 1833, Davenport was established on May 14,1836 by Le Claire, and named after his friend Colonel George Davenport, who was stationed at Fort Armstrong during the war

Illinois
–
Illinois is a state in the midwestern region of the United States, achieving statehood in 1818. It is the 6th most populous state and 25th largest state in terms of land area, the word Illinois comes from a French rendering of a native Algonquin word. For decades, OHare International Airport has been ranked as one of the worlds busiest airports, Illinois has long had a reputation as a bellwether both in social and cultural terms and politics. With the War of 1812 Illinois growth slowed as both Native Americans and Canadian forces often raided the American Frontier, mineral finds and timber stands also had spurred immigration—by the 1810s, the Eastern U. S. Railroads arose and matured in the 1840s, and soon carried immigrants to new homes in Illinois, as well as being a resource to ship their commodity crops out to markets. Railroads freed most of the land of Illinois and other states from the tyranny of water transport. By 1900, the growth of jobs in the northern cities and coal mining in the central and southern areas attracted a new group of immigrants. Illinois was an important manufacturing center during both world wars, the Great Migration from the South established a large community of African Americans in Chicago, who created the citys famous jazz and blues cultures. Three U. S. presidents have been elected while living in Illinois, Abraham Lincoln, Ulysses S. Grant, additionally, Ronald Reagan, whose political career was based in California, was the only U. S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official slogan, Land of Lincoln. The Abraham Lincoln Presidential Library and Museum is located in the capital of Springfield. Illinois is the spelling for the early French Catholic missionaries and explorers name for the Illinois Native Americans. American scholars previously thought the name Illinois meant man or men in the Miami-Illinois language and this etymology is not supported by the Illinois language, as the word for man is ireniwa and plural men is ireniwaki. The name Illiniwek has also said to mean tribe of superior men. The name Illinois derives from the Miami-Illinois verb irenwe·wa he speaks the regular way and this was taken into the Ojibwe language, perhaps in the Ottawa dialect, and modified into ilinwe·. The French borrowed these forms, changing the ending to spell it as -ois. The current spelling form, Illinois, began to appear in the early 1670s, the Illinois name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was Inoka, of unknown meaning and unrelated to the other terms. American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans, the Koster Site has been excavated and demonstrates 7,000 years of continuous habitation

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Tank Mark VIII
–
Production at a site in France was expected to take advantage of US industrial capacity to produce the automotive elements, with the UK producing the armoured hulls and armament. The planned production levels would have equipped the Allied armies with a large tank force that would have broken through the German defensive positions in the planned offensive for 1919. In practice manufacture was slow and only a few vehicles were produced before the end of the war in November 1918, after the war,100 vehicles assembled in the US were used by the US Army until more advanced designs replaced them in 1932. A few tanks that had not been scrapped by the start of World War II were provided to Canada for training purposes, as the First World War progressed, the industrial production capacity of the Entente was taxed to the limit. The output in Britain was limited by labour shortages due to the demand of the armed forces. When the United States of America declared war on Germany on 6 April 1917, after some reflection they decided it was best to leave the initiative to the Americans. Stern did contact the American Military Attaché in London immediately after war was declared, in June 1917 the first American approaches were made, but not by the US Army as they had expected. The US Navy wanted the most modern tanks for its US Marine Corps, at that moment the current British tank project was the Mark VI. It was designed with existing British industrial capacity in mind, posing limits that might be overcome by larger American production facilities, Stern therefore pretended that an even more advanced project had already been in existence which he called the Mark VIII. He invited the Americans to participate and contribute as much as they would like to its design, the Navy was on the brink of sending a team of engineers to Britain when the American Department of War was informed of developments by the US Military Attaché in London. The US Army had set up headquarters in France, in September it decided to form its own tank corps with 25 tank battalions including five heavy tank battalions. To equip the units, Major James A. Drain – a staff officer to General Pershing and responsible for planning of the tank force – provisionally ordered 600 Mark VI tanks from the British in October 1917. The Army tried to convince the Department of War to divert all available tanks to the Army and this posed serious problems for the British government. It now seemed that American involvement in the war would mean a number of tanks available for the British forces. Also on 4 February 1917 binding agreements had been made with the French about tank production, in pushing production through in the early days he had upset civil and military authorities. Stern was appointed in September to the new position of Commissioner for Mechanical Warfare in order to coordinate tank production with the US, Stern went to France to meet the French Minister of Munitions, Louis Loucheur and the American commander-in-chief, John Pershing. Loucheur made it clear from the beginning that France had nothing to offer in terms of existing production facilities and this came as no surprise to Stern who had already prepared an International Plan of ten points that he now managed to get accepted by the Americans

Manufacturing
–
Manufacturing is the value added to production of merchandise for use or sale using labour and machines, tools, chemical and biological processing, or formulation. Manufacturing engineering or manufacturing process are the steps through which raw materials are transformed into a final product, the manufacturing process begins with the product design, and materials specification from which the product is made. These materials are modified through manufacturing processes to become the required part. Manufacturing takes turns under all types of economic systems, in a free market economy, manufacturing is usually directed toward the mass production of products for sale to consumers at a profit. In a collectivist economy, manufacturing is more directed by the state to supply a centrally planned economy. In mixed market economies, manufacturing occurs under some degree of government regulation, modern manufacturing includes all intermediate processes required the production and integration of a products components. Some industries, such as semiconductor and steel manufacturers use the term fabrication instead, the manufacturing sector is closely connected with engineering and industrial design. Examples of major manufacturers in North America include General Motors Corporation, General Electric, Procter & Gamble, General Dynamics, Boeing, Pfizer, examples in Europe include Volkswagen Group, Siemens, and Michelin. Examples in Asia include Sony, Huawei, Lenovo, Toyota, Samsung, in its earliest form, manufacturing was usually carried out by a single skilled artisan with assistants. In much of the world, the guild system protected the privileges. Before the Industrial Revolution, most manufacturing occurred in rural areas, entrepreneurs organized a number of manufacturing households into a single enterprise through the putting-out system. Toll manufacturing is an arrangement whereby a first firm with specialized equipment processes raw materials or semi-finished goods for a second firm, manufacturing provides important material support for national infrastructure and for national defense. On the other hand, most manufacturing may involve significant social and environmental costs, the clean-up costs of hazardous waste, for example, may outweigh the benefits of a product that creates it. Hazardous materials may expose workers to health risks and these costs are now well known and there is effort to address them by improving efficiency, reducing waste, using industrial symbiosis, and eliminating harmful chemicals. The negative costs of manufacturing can also be addressed legally, developed countries regulate manufacturing activity with labor laws and environmental laws. Across the globe, manufacturers can be subject to regulations and pollution taxes to offset the costs of manufacturing activities. Labor unions and craft guilds have played a role in the negotiation of worker rights. Environment laws and labor protections that are available in developed nations may not be available in the third world, tort law and product liability impose additional costs on manufacturing

Logistics
–
Logistics is generally the detailed organization and implementation of a complex operation. In a general sense, logistics is the management of the flow of things between the point of origin and the point of consumption in order to meet requirements of customers or corporations. The resources managed in logistics can include items such as food, materials, animals, equipment. The logistics of physical items usually involves the integration of information flow, material handling, production, packaging, inventory, transportation, warehousing, and often security. In military science, logistics is concerned with maintaining army supply lines while disrupting those of the enemy, since an armed force without resources and transportation is defenseless. Military logistics was already practiced in the ancient world and as modern military have a significant need for logistics solutions, in military logistics, logistics officers manage how and when to move resources to the places they are needed. The complexity of logistics can be modeled, analyzed, visualized, the minimization of the use of resources is a common motivation in all logistics fields. A professional working in the field of management is called a logistician. The prevalent view is that the term comes from the late 19th century. Others attribute a Greek origin to the word, λόγος, meaning reason or speech, λογιστικός, the Oxford English Dictionary defines logistics as the branch of military science relating to procuring, maintaining and transporting material, personnel and facilities. As such, logistics is commonly seen as a branch of engineering that creates people systems rather than machine systems and that being said, from a modeling perspective, there are similarities between operations management and logistics, and companies sometimes use hybrid professionals, with for ex. Director of Operations or Logistics Officer working on similar problems, furthermore, the term supply chain management originally refers to, among other issues, having an integrated vision in of both production and logistics from point of origin to point of production. All these terms may suffer from semantic change as an effect of advertising. Outbound logistics is the related to the storage and movement of the final product. Advance Logistics consists of the required to set up or establish a plan for logistics activities to occur. Distribution logistics has, as main tasks, the delivery of the products to the customer. It consists of processing, warehousing, and transportation. Distribution logistics is necessary because the time, place, and quantity of production differs with the time, place, disposal logistics has as its main function to reduce logistics cost and enhance service related to the disposal of waste produced during the operation of a business

United States Armed Forces
–
The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, from the time of its inception, the military played a decisive role in the history of the United States. A sense of unity and identity was forged as a result of victory in the First Barbary War. Even so, the Founders were suspicious of a permanent military force and it played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold Wars onset, the U. S. military is one of the largest militaries in terms of number of personnel. It draws its personnel from a pool of paid volunteers. As of 2016, the United States spends about $580.3 billion annually to fund its military forces, put together, the United States constitutes roughly 40 percent of the worlds military expenditures. For the period 2010–14, the Stockholm International Peace Research Institute found that the United States was the worlds largest exporter of major arms, the United States was also the worlds eighth largest importer of major weapons for the same period. The history of the U. S. military dates to 1775 and these forces demobilized in 1784 after the Treaty of Paris ended the War for Independence. All three services trace their origins to the founding of the Continental Army, the Continental Navy, the United States President is the U. S. militarys commander-in-chief. Rising tensions at various times with Britain and France and the ensuing Quasi-War and War of 1812 quickened the development of the U. S. Navy, the reserve branches formed a military strategic reserve during the Cold War, to be called into service in case of war. Time magazines Mark Thompson has suggested that with the War on Terror, Command over the armed forces is established in the United States Constitution. The sole power of command is vested in the President by Article II as Commander-in-Chief, the Constitution also allows for the creation of executive Departments headed principal officers whose opinion the President can require. This allowance in the Constitution formed the basis for creation of the Department of Defense in 1947 by the National Security Act, the Defense Department is headed by the Secretary of Defense, who is a civilian and member of the Cabinet. The Defense Secretary is second in the chain of command, just below the President. Together, the President and the Secretary of Defense comprise the National Command Authority, to coordinate military strategy with political affairs, the President has a National Security Council headed by the National Security Advisor. The collective body has only power to the President

Artillery
–
Artillery is a class of large military weapons built to fire munitions far beyond the range and power of infantrys small arms. Early artillery development focused on the ability to breach fortifications, and led to heavy, as technology improved, lighter, more mobile field artillery developed for battlefield use. This development continues today, modern self-propelled artillery vehicles are highly mobile weapons of great versatility providing the largest share of an armys total firepower, in its earliest sense, the word artillery referred to any group of soldiers primarily armed with some form of manufactured weapon or armour. In common speech, the artillery is often used to refer to individual devices, along with their accessories and fittings. However, there is no generally recognised generic term for a gun, howitzer, mortar, and so forth, the United States uses artillery piece, the projectiles fired are typically either shot or shell. Shell is a widely used term for a projectile, which is a component of munitions. By association, artillery may also refer to the arm of service that customarily operates such engines, in the 20th Century technology based target acquisition devices, such as radar, and systems, such as sound ranging and flash spotting, emerged to acquire targets, primarily for artillery. These are usually operated by one or more of the artillery arms, Artillery originated for use against ground targets—against infantry, cavalry and other artillery. An early specialist development was coastal artillery for use against enemy ships, the early 20th Century saw the development of a new class of artillery for use against aircraft, anti-aircraft guns. Artillery is arguably the most lethal form of land-based armament currently employed, the majority of combat deaths in the Napoleonic Wars, World War I, and World War II were caused by artillery. In 1944, Joseph Stalin said in a speech that artillery was the God of War, although not called as such, machines performing the role recognizable as artillery have been employed in warfare since antiquity. The first references in the historical tradition begin at Syracuse in 399 BC. From the Middle Ages through most of the era, artillery pieces on land were moved by horse-drawn gun carriages. In the contemporary era, the artillery and crew rely on wheeled or tracked vehicles as transportation, Artillery used by naval forces has changed significantly also, with missiles replacing guns in surface warfare. The engineering designs of the means of delivery have likewise changed significantly over time, in some armies, the weapon of artillery is the projectile, not the equipment that fires it. The process of delivering fire onto the target is called gunnery, the actions involved in operating the piece are collectively called serving the gun by the detachment or gun crew, constituting either direct or indirect artillery fire. The term gunner is used in armed forces for the soldiers and sailors with the primary function of using artillery. The gunners and their guns are usually grouped in teams called either crews or detachments, several such crews and teams with other functions are combined into a unit of artillery, usually called a battery, although sometimes called a company
31.
Weapon mount
–
A weapon mount is a weapon component used to affix an armament for stabilization. Weapon mounts can be broken down into two categories, static mounts and non-static mounts, a static mount is a non-portable weapon support component used on a self-propelled vehicle. A gun turret protects the crew or mechanism of a weapon, a turret is a rotating weapon platform. This can be mounted on a building or structure such as a coast artillery battery, or on an armoured fighting vehicle. Turrets may be armed with one or more guns, automatic cannons, large-calibre guns, missile launchers. It may be manned or remotely controlled, and is often armoured, a small turret, or sub-turret on a larger one, is called a cupola. The term cupola also describes rotating turrets that carry no weapons but instead are sighting devices, a finial is an extremely small sub-turret or sub-sub-turret mounted on a cupola turret. The protection provided by the turret may be against battle damage or against the weather, conditions and environment in which the weapon or its crew operate. A coaxial mount is mounted beside the primary weapon and thus points in the general direction as the main armament. The term coaxial is a misnomer as the arrangement is often actually paraxial, nearly all main battle tanks and most infantry fighting vehicles have a coaxial machine gun mounted to fire along a parallel axis to the main gun. Coaxial weapons are usually aimed by use of the gun control. It is usually used to infantry or other soft targets when the main gun collateral damage would be excessive. A fixed mount is not moveable with respect to the vehicle, the vehicle must move in order to change direction of fire. Fixed mounts are most commonly found on aircraft, and most commonly direct the forward, along the aircrafts vector of movement, so that a pilot could aim. Some minor aircraft designs used different concept of fixed mounts, as found in Schräge Musik or AC-47 Spooky, a pintle mount is a fixed mount that allows the gun to be freely traversed and/or elevated while keeping the gun in one fixed position. It is most commonly found on armoured vehicles, gunner stations on bomber aircraft, unlike a turret, a pintle has little or no armour protection. A swing mount is a mount that allows a far greater. Utilising a system of one or two articulated arms the gunner can swing the weapon through a wide arc even though the position is fixed relative to the mount
32.
Recoil
–
Recoil is the backward movement of a gun when it is discharged. To apply this counter-recoiling force, modern mounted guns may employ recoil buffering comprising springs and hydraulic recoil mechanisms, early cannons used systems of ropes along with rolling or sliding friction to provide forces to slow the recoiling cannon to a stop. Recoil buffering allows the maximum counter-recoil force to be lowered so that strength limitations of the gun mount are not exceeded, however, the same pressures acting on the base of the projectile are acting on the rear face of the gun chamber, accelerating the gun rearward during firing. This results in the required counter-recoiling force being proportionally lower, modern cannons also employ muzzle brakes very effectively to redirect some of the propellant gasses rearward after projectile exit. This provides a force to the barrel, allowing the buffering system. The same physics affecting recoil in mounted guns and cannons applies to hand-held guns, hands, arms and shoulders have considerable strength and elasticity for this purpose, up to certain practical limits. For this reason, establishing recoil safety standards for small arms remains challenging, a change in momentum of a mass requires a force, according to Newtons first law, known as the law of inertia, inertia simply being another term for mass. That force, applied to a mass, creates an acceleration, according to Newtons second law, the law of momentum -- changing the velocity of the mass changes its momentum. It is important to understand at this point that velocity is not simply speed, velocity is the speed of a mass in a particular direction. In a very technical sense, speed is a scalar, a magnitude, in summation, the total momentum of the system equals zero, surprisingly just as it did before the trigger was pulled. There are two conservation laws at work when a gun is fired, conservation of momentum and conservation of energy, recoil is explained by the law of conservation of momentum, and so it is easier to discuss it separately from energy. The nature of the process is determined by the force of the expanding gases in the barrel upon the gun. It is also determined by the force applied to the gun. The recoil force only acts during the time that the ejecta are still in the barrel of the gun, except for the case of zero-recoil, the counter-recoil force is smaller than the recoil force but lasts for a longer time. Since the recoil force and the force are not matched. In the zero-recoil case, the two forces are matched and the gun will not move when fired. In most cases, a gun is very close to a free-recoil condition, an example of near zero-recoil would be a gun securely clamped to a massive or well-anchored table, or supported from behind by a massive wall. For example, placing the butt of a large caliber gun directly against a wall, the recoil of a firearm, whether large or small, is a result of the law of conservation of momentum

Small arms
–
In international arms control, small arms include revolvers and pistols, rifles and carbines, assault rifles, submachine guns and light machine guns. Together with light weapons, they comprise the Small Arms and Light Weapons protocol, in the U. S. military, small arms are man portable, individual, and crew-served weapon systems used mainly against personnel and lightly armored or unarmored equipment. However, in regard to management, the U. S. Army says small arms/light weapons are, Handguns, shoulder-fired weapons, light automatic weapons up to. Much of the work to address the illegal arms trade is raised in the United Nations Conference on the Illicit Trade in Small Arms. In 2013, the Small Arms Survey said that of the 875 million small arms distributed globally,650 million — almost 75 percent — are in civilian hands, about 200 million are controlled by armed forces and about 26 million by law enforcement agencies. Gang members hold between 2 and 10 million small arms and armed, non-state actors hold about 1.4 million, together, the small-arms arsenals of non-state actors and gangs account for 0.4 to 1.3 percent of the global total.

Grenade launcher
–
A grenade launcher is a weapon that fires a specially-designed large-caliber projectile, often with an explosive, smoke or gas warhead. Today, the term refers to a class of dedicated firearms firing unitary grenade cartridges. The most common type are man-portable, shoulder-fired weapons issued to individuals, Grenade launchers can either come in the form of standalone weapons or attachments mounted to a parent firearm, usually a rifle. Larger crew-served automatic grenade launchers such as the Mk 19 are mounted on tripods or vehicles, some armored fighting vehicles also mount fixed arrays of short range, single-shot grenade launchers as a means of defense. These devices usually fire smoke grenades to conceal the vehicle behind a screen, though can also be loaded with chaff, flares. Vehicle-mounted smoke grenade launchers are known as smoke dischargers. The earliest devices which could conceivably be referred to as grenade launchers were slings, a new method of launching grenades was developed during the First World War and used throughout the Second. The disadvantage of this method is that when a soldier wants to launch a grenade, if they are surprised by a close-range threat while preparing to fire the grenade, they have to reverse the procedure before they can respond with rifle fire. Due to the lack of a barrel, rifle grenades also tend to be difficult to fire accurately compared to underbarrel or standalone designs. One of the first examples of a dedicated breech-loading launcher for unitary explosive grenade rounds was the M79 grenade launcher, the goal for the M79 was the production of a device with greater range than a rifle grenade but more portable than a mortar. Such single-shot devices were replaced in military service with underbarrel grenade launchers. Single shot launchers are still commonly used in riot control operations. This reduces the weight the soldier must carry by eliminating the grenade launchers buttstock, underbarrel 40mm grenade launchers generally have their own trigger group, to fire, one simply changes grips, disengages the safety, and pulls the trigger. In Western systems, the barrel slides forward or pivots to the side to allow reloading, soviet/Russian launchers are instead loaded from the muzzle, with the cartridge casing affixed to the projectile in the style of a mortar shell. Modern launchers often have the option of mounting more sophisticated aiming systems, such as ballistic rangefinders, one AAI submission for SPIW mounted a simple single-action, single-shot breech-loading underbarrel grenade launcher in lieu of the required semi-automatic multi-shot device. With refinement, this was adopted as the M203 grenade launcher in 1968, a variety of lengths of M203 are available along with numerous parts kits to fit it to various rifles aside from the AR15 pattern weapons it was designed for. A variant of the weapon, the M320 Grenade Launcher Module, was salvaged from the failed XM8 program. Further developments led to the GP series of grenade launchers, an automatic grenade launcher or grenade machine gun is a crew-served support weapon which fires explosive rounds in quick succession from an ammunition belt or large-capacity magazine

Simulation
–
Simulation is the imitation of the operation of a real-world process or system over time. The model represents the system itself, whereas the simulation represents the operation of the system over time, Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games. Often, computer experiments are used to study simulation models, Simulation is also used with scientific modelling of natural systems or human systems to gain insight into their functioning, as in economics. Simulation can be used to show the real effects of alternative conditions. Physical simulation refers to simulation in which objects are substituted for the real thing. These physical objects are chosen because they are smaller or cheaper than the actual object or system. Simulation Fidelity is used to describe the accuracy of a simulation, Fidelity is broadly classified as 1 of 3 categories, low, medium, and high. Simulation in failure analysis refers to simulation in which we create environment/conditions to identify the cause of equipment failure and this was the best and fastest method to identify the failure cause. A computer simulation is an attempt to model a real-life or hypothetical situation on a computer so that it can be studied to see how the system works, by changing variables in the simulation, predictions may be made about the behaviour of the system. It is a tool to investigate the behaviour of the system under study. A good example of the usefulness of using computers to simulate can be found in the field of network traffic simulation, in such simulations, the model behaviour will change each simulation according to the set of initial parameters assumed for the environment. Computer simulation is used as an adjunct to, or substitution for. Several software packages exist for running computer-based simulation modeling that makes all the modeling almost effortless, modern usage of the term computer simulation may encompass virtually any computer-based representation. The computer simulates the subject machine, accordingly, in theoretical computer science the term simulation is a relation between state transition systems, useful in the study of operational semantics. Less theoretically, an application of computer simulation is to simulate computers using computers. For example, simulators have been used to debug a microprogram or sometimes commercial application programs, simulators may also be used to interpret fault trees, or test VLSI logic designs before they are constructed. Symbolic simulation uses variables to stand for unknown values, in the field of optimization, simulations of physical processes are often used in conjunction with evolutionary computation to optimize control strategies. Simulation is extensively used for educational purposes and it is frequently used by way of adaptive hypermedia

M198 howitzer
–
The M198 howitzer is a medium-sized, towed 155mm artillery piece, developed for service with the United States Army and Marine Corps. It was commissioned to be a replacement for the WWII-era M114155 mm howitzer and it was designed and prototyped at the Rock Island Arsenal in 1969 with firing tests beginning in 1970 and went into full production there in 1978. It entered service in 1979 and since then 1,600 units have been produced, the M198 is being replaced in US and Australian service by the M777 howitzer. The M198155 mm howitzer weighs less than 16,000 pounds, the M198 is a towed howitzer that is transported tail first. The gun tube can be rotated over the trail legs to reduce its length, though this requires removal of the muzzle brake. When firing, the weapon is lowered onto its baseplate rather than being anchored to the ground, the breech is operated manually via a screw type mechanism that rests low in an ergonomic position. The M198 fires non-fixed ammunition and can be loaded with a variety of propellants, the effective range is 18,100 meters when firing standard projectiles, which increases to 30,000 meters when firing rocket-assisted projectiles and guided ammunition. With the 52-caliber modification the range can surpass 40,000 meters, the weapon system requires a crew of 9 and is capable of firing at a maximum rate of four rounds per minute, two sustained. The M198 is deployed in separate corps- and army-level field artillery units, as well as in artillery battalions of light and it also provides field artillery fire support for all Marine Air-Ground Task Force organizations. High Explosive, Explosive Composition B material packed into a thick, internally scored shell which causes a large blast, the kill zone is approximately a radius of 50 meters and casualty radius is 100 meters. The Marine Corps and US Army also uses the M795 High Explosive round, rocket Assisted Projectile A rocket-assisted HE M549 round that adds to the maximum range of the normal HE. For the 155 mm RAP round, max range is 30.1 kilometres, white Phosphorus A base-ejecting projectile which can come in two versions, felt-wedge and standard. White phosphorus smoke is used to fires, burn a target. Illumination Illumination projectiles are base-ejecting rounds which deploy a parachute flare ideally 600 meters above the ground. Illumination rounds are used in conjunction with HE rounds, to illuminate the target area so that HE rounds can be fired more effectively. Illumination rounds can also be used during the daytime to mark targets for aircraft, the M485 Illumination round burns for 120 seconds. Dual-Purpose Improved Conventional Munition A base-ejecting projectile that drops 88 bomblets above a target, each bomblet has a shaped-charge munition capable of penetrating two inches of solid steel as well as a fragmentation casing which is effective against infantry in the open. The DPICM round is effective against armored vehicles, even tanks, area Denial Artillery Munition System An artillery round that releases anti-personnel mines

M119 howitzer
–
The M119 howitzer is the US designation for the L119 light gun, a lightweight British 105 mm howitzer also used by the United States Army. It can be airlifted by helicopter, or dropped by parachute. It does not need a recoil pit, the howitzer was designed and produced by the British Royal Ordnance Factories as the L118 light gun. In the L118 configuration, the 105 mm ammunition is cased separate loading ammunition, the L118 entered service with the British Army in 1976 and is used by parachute and commando field artillery regiments. It saw combat during the Falklands War, where the 30 guns in action fired up to 400 rounds per gun per day, the most powerful propellant charge available. The L119 is the L118 reconfigured to fire NATO-standard US/Nato 105 mm semi-fixed ammunition, in 1987 an agreement was reached to produce the L119 under license by the US as the M119, to replace the M102 howitzer. It entered service with 7th Infantry Division, Fort Ord, California, some improvements were made to produce the M119A1, including increasing its extreme low temperate envelope from −30 °C to −45 °C, improving maintainability. The Army renewed contracts for the M119 to be produced by the Rock Island Arsenal-Joint Manufacturing & Technology Center at Rock Island, the 105 mm M20A1 cannon was produced by US Army Watervliet Arsenal. Other divisions may be of mixed composition between armor, Stryker, and infantry brigade combat teams, with armor having M109A6s Paladins, for example, two of four are IBCTs with M119s in the 25th Infantry Division. National guard light field artillery battalions assigned to IBCTs also have M119s and it is routinely airdropped in airborne operations and sling-loaded under CH-47 Chinook or UH-60 Black Hawk helicopters in air assault operations. In April 2009, the M119A2 howitzer was being fielded by the 4th Infantry Combat Brigade of the 3rd Infantry Division to provide support in operations in Afghanistan. It was the brigade in the division equipped with it. Firing platoons were equipped with larger, also digital M777A2 howitzers, and the M119A3 was more admired for being faster, lighter. Project Manager for Towed Artillery Systems has developed several upgrades for the M119A3 including digital fire control, increased low temperature capability from −25 to −51 °F, and the M20 breech

Howitzer
–
In the taxonomies of artillery pieces used by European armies in the 17th to 20th centuries, the howitzer stood between the gun and the mortar. Howitzers, like other artillery equipment, are organized in groups called batteries. The English word howitzer comes from the Czech word houfnice, from houf, crowd, haufen, sometimes in the compound Gewalthaufen, also designated a pike square formation in German. This is particularly true in the forces of the United States. Because of this practice, the howitzer is used in some armies as a generic term for any kind of artillery piece that is designed to attack targets using indirect fire. Thus, artillery pieces that bear resemblance to howitzers of earlier eras are now described as howitzers. Most other armies in the reserve the word howitzer for guns with barrel lengths 15 to 25 times their caliber. The British had a method of nomenclature. In the 18th century, they adopted projectile weight for guns replacing the old naming system of culverin, saker, mortars had been categorized by calibre in inches in the 17th century and this was inherited by howitzers. The modern howitzers were invented in Sweden towards the end of the 17th century, originally intended for use in siege warfare, they were particularly useful for delivering cast-iron shells filled with gunpowder or incendiary materials into the interior of fortifications. In the middle of the 18th century, a number of European armies began to introduce howitzers that were enough to accompany armies in the field. Though usually fired at the high angles of fire used by contemporary siege howitzers. Rather, as the guns of the day were usually restricted to inert projectiles. Many, for the sake of simplicity and rapidity of fire, the Abus gun was an early form of howitzer in the Ottoman Empire. In 1758 the Russian Empire introduced a type of howitzer, with a conical chamber, called a licorne. The most famous of these gun-howitzers was the Napoleon 12-pounder, a weapon of French design that saw service in the American Civil War. The longest-serving artillery piece of the 19th century was the mountain howitzer, in 1859, the armies of Europe began to rearm field batteries with rifled field guns. These new field pieces used cylindrical projectiles that, while smaller in caliber than the spherical shells of smoothbore field howitzers, moreover, their greater range let them create many of the same effects that previously required the sharply curved trajectories of smoothbore field howitzers

Chattanooga, Tennessee
–
Chattanooga is a city in the U. S. state of Tennessee, with a population of 176,588 in 2015. The fourth-largest Tennessee city, it is the seat of Hamilton County, located in southeastern Tennessee in East Tennessee, on the Tennessee River, served by multiple railroads and Interstate highways, Chattanooga is a transit hub. The city, with elevation of approximately 680 feet, lies at the transition between the ridge-and-valley portion of the Appalachian Mountains and the Cumberland Plateau. Surrounded by mountains and ridges, the nickname for Chattanooga is the Scenic City. Unofficial nicknames include River City, Chatt, Nooga, Chattown, Chattanooga is internationally known for the 1941 song Chattanooga Choo Choo by Glenn Miller and his orchestra. Chattanooga is home to the University of Tennessee at Chattanooga and Chattanooga State Community College, the city has its own typeface, Chatype, which was launched in August 2012. The first inhabitants of the Chattanooga area were Native Americans, sites dating back to the Upper Paleolithic period showed continuous occupation through the Archaic, Woodland, Mississippian/Muskogean/Yuchi, and Cherokee. The Chickamauga Mound near the mouth of the Chickamauga Creek is the oldest remaining visible art in Chattanooga, the Citico town and mound site was the most significant Mississippian/Muscogee landmark in Chattanooga up to 1915. The first part of the name Chattanooga derives from the Muskogean word cvto /chắtȯ/ – rock, the latter may be derived from a regional suffix -nuga meaning dwelling or dwelling place. In 1816 John Ross, who later became Principal Chief, established Rosss Landing, located along what is now Broad Street, it became one of the centers of Cherokee Nation settlement, which also extended into Georgia and Alabama. Their journey west became known as the Trail of Tears for their exile, the US Army used Rosss Landing as the site of one of three large internment camps, or emigration depots, where Native Americans were held prior to the journey on the Trail of Tears. One of the internment camps was located in Fort Payne, Alabama, in 1839, the community of Rosss Landing incorporated as the city of Chattanooga. The city grew quickly, initially benefiting from a location well-suited for river commerce, with the arrival of the railroad in 1850, Chattanooga became a boom town. During the American Civil War, Chattanooga was a center of battle, during the Chickamauga Campaign, Union artillery bombarded Chattanooga as a diversion and occupied it on September 9,1863. Following the Battle of Chickamauga, the defeated Union Army retreated to safety in Chattanooga, the next day, the Battle of Lookout Mountain was fought, driving the Confederates off the mountain. On November 25, Grants army routed the Confederates in the Battle of Missionary Ridge and these battles were followed the next spring by the Atlanta Campaign, beginning just over the nearby state line in Georgia and moving southeastward. After the war ended, the city became a railroad hub and industrial. The largest flood in Chattanoogas history occurred in 1867, before the Tennessee Valley Authority system was created in 1933 by Congress, the flood crested at 58 feet and completely inundated the city

United States Colored Troops
–
The United States Colored Troops were regiments in the United States Army composed primarily of African-American soldiers. Other people of color who were not of African descent, such as Native Americans Pacific Islanders, the USCT was the precursor to the Buffalo Soldier regiments in the American Old West. The U. S. Congress passed the Confiscation Act of 1862 in July 1862 and it freed slaves whose owners were in rebellion against the United States, and Militia Act of 1862 empowered the President to use freed slaves in any capacity in the army. Lincoln opposed early efforts to recruit soldiers, although he accepted the Armys using them as paid workers. Native American also played a significant role in the regiments of the American Civil War. In September 1862, Lincoln issued his preliminary Emancipation Proclamation, announcing that all slaves in rebellious states would be free as of January 1, recruitment of colored regiments began in full force following the Proclamation in January 1863. Regiments, including infantry, cavalry, engineers, light artillery, approximately 175 regiments comprising more than 178,000 free blacks and freedmen served during the last two years of the war. Their service bolstered the Union war effort at a critical time, by wars end, the men of the USCT made up nearly one-tenth of all Union troops. The USCT suffered 2,751 combat casualties during the war, disease caused the most fatalities for all troops, both black and white. USCT regiments were led by officers, while rank advancement was limited for black soldiers. The Supervisory Committee for Recruiting Colored Regiments in Philadelphia opened the Free Military Academy for Applicants for the Command of Colored Troops at the end of 1863. For a time, black soldiers received less pay than their white counterparts, notable members of USCT regiments included Martin Robinson Delany and the sons of Frederick Douglass. The courage displayed by colored troops during the Civil War played an important role in African Americans gaining new rights, before the USCT was formed, several volunteer regiments were raised from free black men, including freedmen in the South. In 1863 a former slave, William Henry Singleton, helped recruit 1,000 blacks from escaped slaves in New Bern and he became a sergeant in the 35th USCT. Freedmen from the Roanoke Island Freedmens Colony, established in 1863 on the island, also formed part of the Free North Carolina Colored Volunteers, nearly all of the volunteer regiments were converted into USCT units. In 1922 Singleton published his memoir of his journey from slavery to freedom, glad to participate in reunions, years later at the age of 95, he marched in a Grand Army of the Republic event in 1938. Four regiments were considered Regular units, rather than auxiliaries and their veteran status allowed them to get valuable federal government jobs after the war, from which African Americans had usually been excluded in earlier years. But, the men received no recognition for combat honors

Rock Island National Cemetery
–
Rock Island National Cemetery is a United States National Cemetery located within Rock Island Arsenal near the city of Rock Island, Illinois. Administered by the United States Department of Veterans Affairs, it encompasses 66 acres, the cemetery is also nearing compliance with the National Shrine guidelines, due to its use of college students during the summer to reset and realign stones. When looking from any one stone there should be seven lines visible, the cemetery was established in 1863 as a place to inter the remains of American Civil War Union army soldiers. Its initial placement interfered with expansion of the Arsenals facilities, so it was moved to a location on the end of the island. Civil War veterans who were interred in Oakdale Cemetery in Davenport, property transfers from the Arsenal in 1926,1936, and 1950 increased the cemeterys area. There are plans for expansion of this cemetery including an addition pavilion, more land.

Five of these weapons were used at the Battle of the Little Bighorn, twenty-five percent of the collections small firearms are not on display, including three rare rifles. Jodean Murdock, education curator, says that the firearms get the most attention from visitors, the museum has a research center located in its basement, containing books, maps, manuals, and magazines, among others. A Childrens Discovery Room was created with uniforms and hats for children to try on, hygrothermographs and a thermostat are used to control the temperature and humidity in the collection rooms so that the items contained within them are not damaged. The museum collections were reduced in 2016, with almost 3,200 pieces being moved to a warehouse operated by the Army, there was also a large reduction in staff. The museums gift shop went out of business as well due to falling sales

Every year, a small number of cadets do this. The academys traditions have influenced other institutions because of its age and it was the first American college to have an accredited civil-engineering program and the first to have class rings, and its technical curriculum was a model for later engineering schools. West Points student body has a rank structure and lexicon. All cadets reside on campus and dine together en masse on weekdays for breakfast, the academy fields fifteen mens and nine womens National Collegiate Athletic Association sports teams.

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

Prison
–
Besides their use for punishing crimes, jails and prisons are frequently used by authoritarian regimes against perceived opponents. Prisons often have facilities that are designed with long term confinement in mind in comparison to jails. In times of war, prisoners of war or detainees may be detained in prisons or prisoner of war camps. The use of prisons can be traced back to the rise of the state as a form of social organization, corresponding with the advent of the state was the development of written language, which enabled the creation of formalized legal codes as official guidelines for society. The best known of early legal codes is the Code of Hammurabi. Some Ancient Greek philosophers, such as Plato, began to develop ideas of using punishment to reform instead of simply using it as retribution. Imprisonment as a penalty was used initially for those who could not afford to pay their fines, eventually, since impoverished Athenians could not pay their fines, leading to indefinite periods of imprisonment, time limits were set instead. The prison in Ancient Athens was known as the desmoterion, the Romans were among the first to use prisons as a form of punishment, rather than simply for detention. A variety of existing structures were used to house prisoners, such as cages, basements of public buildings. One of the most notable Roman prisons was the Mamertine Prison, the Mamertine Prison was located within a sewer system beneath ancient Rome and contained a large network of dungeons where prisoners were held in squalid conditions, contaminated with human waste. Forced labor on public projects was also a common form of punishment. In many cases, citizens were sentenced to slavery, often in ergastula, during the Middle Ages in Europe, castles, fortresses, and the basements of public buildings were often used as makeshift prisons. Another common punishment was sentencing people to slavery, which involved chaining prisoners together in the bottoms of ships. However, the concept of the modern prison largely remained unknown until the early 19th-century, Punishment usually consisted of physical forms of punishment, including capital punishment, mutilation, flagellation, branding, and non-physical punishments, such as public shaming rituals. However, an important innovation at the time was the Bridewell House of Corrections, located at Bridewell Palace in London and these houses held mostly petty offenders, vagrants, and the disorderly local poor. In these facilities, inmates were given jobs, and through prison labor they were taught how to work for a living, by the end of the 17th century, houses of correction were absorbed into local prison facilities under the control of the local justice of the peace. From the late 17th century and during the 18th century, popular resistance to public execution, rulers began looking for means to punish and control their subjects in a way that did not cause people to associate them with spectacles of tyrannical and sadistic violence. They developed systems of mass incarceration, often with hard labor, the prison reform movement that arose at this time was heavily influenced by two somewhat contradictory philosophies

75mm pack howitzer
–
The 75mm Pack Howitzer M1 was an artillery piece used by the United States. It was designed in the 1920s to meet a need for a howitzer that could be moved across difficult terrain, the gun and carriage was designed so that it could be broken down into several pieces to be carried by pack animals. The gun saw combat in World War II with the United States Army, with US Marine Corps, in addition to the pack / air portable configuration, the gun was mounted on a conventional carriage to serve as a field artillery piece. The M2 and M3 are derived vehicle mounted howitzers used in the 75mm HMC M8, in addition, the M1 in its original version was mated to a number of other self-propelled carriages, though only one of those – 75mm HMC T30 – reached mass production. The 75 mm pack howitzer was designed in the United States in the 1920s to meet a need for a piece that could be moved across difficult terrain. In August 1927, the weapon was standardized as Howitzer, Pack, due to meager funding, production rates were low, by 1940, only 91 pieces were manufactured. It was not until September 1940 that the howitzer was put into mass production, by then, the M1 had been succeeded by the slightly modified M1A1. The only significant changes during the production period were carriage improvements. The original carriage M1 was of box type, with wooden wheels. The requirement for a lightweight howitzer for airborne troops led to the introduction of the M8 carriage, another requirement, from the cavalry branch of the US Army, resulted in a completely different family of field howitzer split trail carriages M3A1 / M3A2 / M3A3. However, only limited numbers of the M1 field howitzer variant were built, the howitzer M1 or M1A1 consisted of tube and breech, which were joined together by interrupted threads, allowing for quick assembly and disassembly. One eighth of a turn was required to connect or disconnect tube, the tube had uniform, right hand rifling with one turn in 20 calibers. The breech was of horizontal sliding type, with continuous-pull firing mechanism. Both recoil buffer and recuperator were located under the barrel, the pack howitzer carriage M1 had dismantling construction. The carriage was of box type, with steel-rimmed wooden wheels. The carriage M8 was identical, except for axle arms and wheels, the howitzer on carriage M8 could be broken down into seven mule loads or into nine parachute loads. It could also be towed by vehicle such as 1/4 ton jeep, the field howitzer carriages of the M3 family were non-dismantling, split trail. All these were fitted with metal wheels with pneumatic tires, all had an additional retractable support, in firing position, the firing base could be lowered and wheels raised, leaving the weapon to rest on the firing base and trails
