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

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

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

Second Battle of Bull Run
–
The Second Battle of Bull Run or Battle of Second Manassas was fought August 28–30,1862 in Prince William County, Virginia, as part of the American Civil War. Withdrawing a few miles to the northwest, Jackson took up strong concealed defensive positions on Stony Ridge, on August 28,1862, Jackson attacked a Union column just east of Gainesville, at Brawners Farm, resulting in a stalemate but successfully getting Popes attention. On that same day, the wing of Lees army commanded by Maj. Gen. James Longstreet broke through light Union resistance in the Battle of Thoroughfare Gap, Pope became convinced that he had trapped Jackson and concentrated the bulk of his army against him. On August 29, Pope launched a series of assaults against Jacksons position along a railroad grade. The attacks were repulsed with casualties on both sides. At noon, Longstreet arrived on the field from Thoroughfare Gap, on August 30, Pope renewed his attacks, seemingly unaware that Longstreet was on the field. The Union left flank was crushed and the army was back to Bull Run. Only an effective Union rear guard action prevented a replay of the First Manassas defeat, Popes retreat to Centreville was nonetheless precipitous. Success in this battle emboldened Lee to initiate the ensuing Maryland Campaign, after the collapse of Maj. Gen. George B. McClellans Peninsula Campaign in the Seven Days Battles of June 1862, Pope had achieved some success in the Western Theater, and Lincoln sought a more aggressive general than McClellan. Popes mission was to two basic objectives, protect Washington and the Shenandoah Valley, and draw Confederate forces away from McClellan by moving in the direction of Gordonsville. This allowed him to relocate Jackson to Gordonsville to block Pope, Lee had larger plans in mind. Since the Union Army was split between McClellan and Pope and they were separated, Lee saw an opportunity to destroy Pope before returning his attention to McClellan. He committed Maj. Gen. A. P. Hill to join Jackson with 12,000 men, on August 3, General-in-Chief Henry W. Halleck directed McClellan to begin his final withdrawal from the Peninsula and to return to Northern Virginia to support Pope. McClellan protested and did not begin his redeployment until August 14, on August 9, Nathaniel Bankss corps attacked Jackson at Cedar Mountain, gaining an early advantage, but a Confederate counterattack led by A. P. Hill drove Banks back across Cedar Creek. Jacksons advance was stopped, however, by the Union division of Brig. Gen. James B, by now Jackson had learned that Popes corps were all together, foiling his plan of defeating each in separate actions. He remained in position until August 12, then withdrew to Gordonsville, on August 13, Lee sent Longstreet to reinforce Jackson. From August 22 to 25, the two fought a series of minor actions along the Rappahannock River

Artillery battery
–
The term is also used in a naval context to describe groups of guns on warships. Historically the term referred to a cluster of cannon in action as a group. Such batteries could be a mixture of cannon, howitzer, or mortar types, a siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannon in a fixed fortification and they were usually organised with between six and 12 ordnance pieces, often including cannon and howitzers. By the late 19th century battery had become standard mostly replacing company or troop, in the 20th century the term was generally used for the company level sub-unit of an artillery branch including field, air-defence, anti-tank and position. 20th-century firing batteries have been equipped with mortars, guns, howitzers, rockets, during the Napoleonic Wars some armies started grouping their batteries into larger administrative and field units. Groups of batteries combined for field combat employment called Grand Batteries by Napoleon, administratively batteries were usually grouped in battalions, regiments or squadrons and these developed into tactical organisations. These were further grouped into regiments, simply group or brigades, to further concentrate fire of individual batteries, from World War I they were grouped into artillery divisions in a few armies. Coastal artillery sometimes had completely different organizational terms based on shore defence sector areas, the rank of a battery commander has also varied, but is usually a lieutenant, captain, or major. The number of guns, howitzers, mortars or launchers in a battery has also varied. In the 19th century four to 12 guns was usual as the number to maneuver into the gun line. By late 19th century the artillery battery was divided into a gun line. The gun line consisted of six guns and 12 ammunition mules, during the American Civil War, artillery batteries often consisted of six field pieces for the Union Army and four for the Confederate States Army, although this varied. Batteries were divided into sections of two guns apiece, each section normally under the command of a lieutenant, the full battery was typically commanded by a captain. Often, particularly as the war progressed, individual batteries were grouped into battalions under a major or colonel of artillery, in the 20th century it varied between four and 12 for field artillery, or even two pieces for very heavy pieces. Other types of such as anti-tank or anti-aircraft have sometimes been larger. Some batteries have been dual-equipped with two different types of gun or mortar, and taking whichever was more appropriate when they deployed for operations, from the late 19th century field artillery batteries started to become more complex organisations. Fixed artillery refers to guns or howitzers on mounts that were anchored in one spot, or on carriages intended to be moved only for the purposes of aiming

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
