Walls of Dubrovnik
–
In 1979, the old city of Dubrovnik, which includes a substantial portion of the old walls of Dubrovnik, joined the UNESCO list of World Heritage Sites. The oldest systems of fortifications around the town were likely wooden palisades, todays intact city walls, constructed mainly during the 12th–17th centuries, mostly a double line, have long been a source of pride for Dubrovnik. The walls run a course of approximately 1,940 metres in length, encircling most of the old city. The bulk of the walls and fortifications were constructed during the 14th and 15th centuries. The walls were reinforced by three circular and 14 quadrangular towers, five bastions, two angular fortifications and the large St. Johns Fortress. Land walls were reinforced by one larger bastion and nine smaller semicircular ones, like the casemate Fort Bokar. The moat that ran around the section of the city walls. The construction of the first limestone forts around the city began in the Early Middle Ages, but, the old chronicles say that some sort of castle reliably existed on the Lave peninsula quite a long time prior to that. It is certain that the town on Laus Island was also surrounded by defensive walls. The fact that Dubrovnik managed to survive a fifteen-month-long invasion by the Saracens in the 9th century proves how well the city was fortified. The city first spread towards the eastern part of the islet. The name Pustijerna comes from the Latin statement post terra, which means outside the town, in the 9th and 10th centuries, the defensive wall enclosed the eastern portion of the city. During this same period, Dubrovnik and the surrounding area were described as a part of the Croatian entity. In his book Nuzhat al-Mushataq fi ikhtiraq al-afaq from 1154, he mentioned Dubrovnik as the southernmost city of the country of Croatia and Dalmatia, the basic city plan dates from 1292, when the port was rebuilt following a fire. The whole city was enclosed in the 13th century, except for the Dominican monastery. Being constructed very solidly, the walls were generally unaffected by an earthquake occurring in 1667. The city was also under latent danger of attack by the Venetians, for centuries the people of Dubrovnik were able to preserve their city-republic by skillful maneuvering between East and West. A strategic treaty with Turkey protracted Ragusa’s liberty and maintained the opportunity for a major trading role between the Ottoman Empire and Europe, the irregular parallelogram surrounding Dubrovnik consists of four strong fortresses at its most significant points

Croatia
–
Croatia, officially the Republic of Croatia, is a sovereign state between Central Europe, Southeast Europe, and the Mediterranean. Its capital city is Zagreb, which one of the countrys primary subdivisions. Croatia covers 56,594 square kilometres and has diverse, mostly continental, Croatias Adriatic Sea coast contains more than a thousand islands. The countrys population is 4.28 million, most of whom are Croats, the Croats arrived in the area of present-day Croatia during the early part of the 7th century AD. They organised the state into two duchies by the 9th century, tomislav became the first king by 925, elevating Croatia to the status of a kingdom. The Kingdom of Croatia retained its sovereignty for nearly two centuries, reaching its peak during the rule of Kings Petar Krešimir IV and Dmitar Zvonimir, Croatia entered a personal union with Hungary in 1102. In 1527, faced with Ottoman conquest, the Croatian Parliament elected Ferdinand I of the House of Habsburg to the Croatian throne. In 1918, after World War I, Croatia was included in the unrecognized State of Slovenes, Croats and Serbs which seceded from Austria-Hungary, a fascist Croatian puppet state backed by Fascist Italy and Nazi Germany existed during World War II. After the war, Croatia became a member and a federal constituent of the Socialist Federal Republic of Yugoslavia. On 25 June 1991 Croatia declared independence, which came wholly into effect on 8 October of the same year, the Croatian War of Independence was fought successfully during the four years following the declaration. A unitary state, Croatia is a republic governed under a parliamentary system, the International Monetary Fund classified Croatia as an emerging and developing economy, and the World Bank identified it as a high-income economy. Croatia is a member of the European Union, United Nations, the Council of Europe, NATO, the World Trade Organization, the service sector dominates Croatias economy, followed by the industrial sector and agriculture. Tourism is a significant source of revenue during the summer, with Croatia ranked the 18th most popular tourist destination in the world, the state controls a part of the economy, with substantial government expenditure. The European Union is Croatias most important trading partner, since 2000, the Croatian government constantly invests in infrastructure, especially transport routes and facilities along the Pan-European corridors. Internal sources produce a significant portion of energy in Croatia, the rest is imported, the origin of the name is uncertain, but is thought to be a Gothic or Indo-Aryan term assigned to a Slavic tribe. The oldest preserved record of the Croatian ethnonym *xъrvatъ is of variable stem, the first attestation of the Latin term is attributed to a charter of Duke Trpimir from the year 852. The original is lost, and just a 1568 copy is preserved—leading to doubts over the authenticity of the claim, the oldest preserved stone inscription is the 9th-century Branimir Inscription, where Duke Branimir is styled as Dux Cruatorvm. The inscription is not believed to be dated accurately, but is likely to be from during the period of 879–892, the area known as Croatia today was inhabited throughout the prehistoric period

Ottoman dynasty
–
The Ottoman dynasty was made up of the members of the imperial House of Osman. According to Ottoman tradition, the family originated from the Kayı tribe branch of the Oghuz Turks, the Ottoman dynasty, named after Osman I, ruled the Ottoman Empire from c.1299 to 1922. During much of the Empires history, the sultan was the regent, head of state. The imperial family was deposed from power and the sultanate was abolished on 1 November 1922 after the Turkish War of Independence, the Republic of Turkey was declared the following year. The living members of the dynasty were sent into exile as persona non gratae, though some have been allowed to return. In its current form, the family is known as the Osmanoğlu family, before Orhans proclamation of the dynasty, the tribe was known as the Bilecik Söğüt Beylik or Beys but was renamed Osmanlı in honor of Osman. The Ottoman dynasty is known in modern Turkish as Osmanlı Hanedanı, meaning House of Osman, in Ottoman Turkish it was known as Hanedan-ı Âl-i Osman, thus they still formally acknowledged the sovereignty of the Seljuk Empire and its successor, the Seljuk Sultanate of Rûm. The first Ottoman ruler to claim the title of Sultan was Murad I. The holder of the title Sultan was in Arabic-Islamic dynasties originally the power behind the throne of the Caliph in Bagdad, the Ottoman sultans also claimed the title of Caliph starting with Murad I, who transformed the Ottoman state into a transcontinental empire. With the Conquest of Constantinople in 1453, Sultan Mehmed II Fatih claimed the title Kaysar-i-Rûm Emperor of Rome and he appointed the Patriarch of Constantinople Gennadius Scholarius, whom he protected and whose status he elevated into leader of all the Eastern Orthodox Christians. As Emperor of Rome he laid claim to all Roman territories, Sultan Mehmed II also took the title of Padishah, a Persian title meaning Master of Kings and ranking as Emperor, claiming superiority among the other kings. He was the first Ottoman ruler to adopt the title of Padishah. The Ottoman claim to caliphate was strengthened when they defeated the Mamluks in 1517, as the empire grew, sultans adopted secondary titles expressing the empires claim to be the legitimate successor of the absorbed states. Furthermore, they tended to enumerate even regular provinces, not unlike the long lists of -mainly inherited- feudal titles in the style of many Christian European monarchs. Some early Ottoman Sultans even had to accept the status in the eyes of a foreign overlord. However, the Ottoman Caliphate too was abolished soon afterwards, and Abdulmecid II was utterly deposed and expelled from Turkey with the rest of the Ottoman dynasty on 3 March 1924

Mersin Province
–
The Mersin Province is a province in southern Turkey, on the Mediterranean coast between Antalya and Adana. The provincial capital is the city of Mersin and the major town is Tarsus. The province is part of Çukurova, a geographical, economical and cultural region, in 2002, the provinces name was changed from İçel to Mersin but the province retained the license plate number of 33, İçel having been the 33rd in the alphabetical order of Turkish province names. There are many high meadows and small plains between 700 and 1500m, the coastal strip has many large areas of flatland, formed from soil brought down by rivers and streams running off the mountains. This is fertile land, the largest area being the plain of Tarsus, the largest rivers are the Göksu and the Berdan, but there are many small streams running into lakes, reservoirs or the Mediterranean sea. Mersin has 321 km of coastline, much of it sandy beach, with all this activity a modern city has grown with a university and other major amenities. About 50% of the population of the province is younger than 24 years of age, about 43% of the male population and about 27% of the female population graduated from middle school. Urban population growth rate is 2. 42%, in summer the hills are a popular retreat from the high humidity and extreme heat on the coast. West of Mersin includes bays, and little islands, yacht touring is a tourism income in these areas. In antiquity this coast was part of Cilicia, named for a Phoenician or Assyrian prince that had settled here, trade from Syria and Mesopotamia over the mountains to central Anatolia passed through here, through the Cilician Gates. The geographer Strabo, described the region as being divided into Rugged Cilicia, the capital of both sections of Cilicia was Tarsus and Mersin was its seaport. Mersin province is divided into thirteen districts four of which are included within the municipality of Mersin city. Silifke - ancient Seleucia Pieria, buildings include the church of Aya Tekla, the ancient Roman town of Soloi-Pompeiopolis, now within the city. About Mersin The ancient Roman town of Anemurium, adjacent to the town of Anamur. Another ancient city of Elaiussa Sebaste,55 km from the city of Mersin, castles including Mamure, Kızkalesi and Namrun

Fortification
–
Fortifications are military constructions or buildings designed for the defense of territories in warfare, and also used to solidify rule in a region during peace time. Humans have constructed defensive works for many thousands of years, in a variety of increasingly complex designs, the term is derived from the Latin fortis and facere. From very early history to modern times, walls have been a necessity for cities to survive in a changing world of invasion. Some settlements in the Indus Valley Civilization were the first small cities to be fortified, in ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae. A Greek Phrourion was a collection of buildings used as a military garrison. These construction mainly served the purpose of a tower, to guard certain roads, passes. Though smaller than a fortress, they acted as a border guard rather than a real strongpoint to watch. The art of setting out a camp or constructing a fortification traditionally has been called castramentation since the time of the Roman legions. Fortification is usually divided into two branches, permanent fortification and field fortification, there is also an intermediate branch known as semi-permanent fortification. Castles are fortifications which are regarded as being distinct from the fort or fortress in that they are a residence of a monarch or noble. Roman forts and hill forts were the antecedents of castles in Europe. The Early Middle Ages saw the creation of towns built around castles. Medieval-style fortifications were made obsolete by the arrival of cannons in the 14th century. Fortifications in the age of black powder evolved into much lower structures with greater use of ditches and earth ramparts that would absorb, Walls exposed to direct cannon fire were very vulnerable, so were sunk into ditches fronted by earth slopes. The arrival of explosive shells in the 19th century led to yet another stage in the evolution of fortification, steel-and-concrete fortifications were common during the 19th and early 20th centuries. However the advances in warfare since World War I have made large-scale fortifications obsolete in most situations. Demilitarized zones along borders are arguably another type of fortification, although a passive kind, many military installations are known as forts, although they are not always fortified. Larger forts may be called fortresses, smaller ones were known as fortalices

Armoured fighting vehicle
–
An armoured fighting vehicle is a combat vehicle, protected by strong armour and generally armed with weapons, which combines operational mobility, tactical offensive, and defensive capabilities. AFVs can be wheeled or tracked and it is not uncommon for AFVs to be simply referred to as armour. Armoured fighting vehicles are classified according to their role on the battlefield. This classification is not absolute, at different times different countries will classify the vehicle in different roles. For example, armoured carriers were generally replaced by infantry fighting vehicles in a similar role. Modern armoured fighting vehicles are the realization of an ancient concept, War machines with rudimentary armour have been used in battle for millennia. These designs historically struggled between the paradox of exposed-mobility, effective-firepower and cumbersome-protection, Siege engines, such as battering rams and trebuchets, would often be armoured in order to protect the crews from the defenders. Very large movable siege towers, helepolis were developed by Polyidus of Thessaly, the idea of a vehicle with a tortoise like cover has been known since antiquity. Frequently cited is Leonardo da Vincis 15th century sketch of a mobile, protected gun platform, the machine was to be mounted on four wheels which would be turned by the crew through a system of hand cranks and cage gears. Leonardo quoted I will build armored wagons which will be safe, there will be no obstacle which it cannot overcome. Modern replicas have demonstrated that the crew would have been able to move it over only short distances. The war wagon were medieval weapon-platforms developmed during the Hussite Wars around 1420 by Hussite forces rebelling in Bohemia. These heavy wagon were given protective sides with firing slits and heavy firepower from either a cannon or a force of hand-gunners and crossbowmen, supported by infantry using pikes, heavy arquebuses mounted on wagons were called arquebus à croc. These carried a ball of about 3.5 ounces, the first modern AFVs were armed cars, dating back virtually to the invention of the motor car. The Motor Scout was designed and built by British inventor F. R. Simms in 1898 and it was the first armed petrol engine powered vehicle ever built. The vehicle was a De Dion-Bouton quadricycle with a mounted Maxim machine gun on the front bar, an iron shield offered some protection for the driver from the front, but it lacked all-around protective armour. The armoured car was the first modern fully armoured fighting vehicle, the first of these was the Simms Motor War Car, designed by Simms and built by Vickers, Sons & Maxim in 1899. The vehicle had Vickers armour 6 mm thick and was powered by a four-cylinder 3. 3-litre 16 hp Cannstatt Daimler engine giving it a speed of around 9 miles per hour

Hut
–
A hut is a primitive dwelling, which may be constructed of various local materials. A hut is a shape of a lower quality than a house, huts exist in practically all nomadic cultures. Some huts are transportable and can stand most conditions of weather, the designs in tropical and sub-tropical areas favour high airflow configurations built from non-conducting materials, which allow heat dissipation. The term house or home is considered by some to be more appropriate, in the Western world the word hut is often used for a wooden shed. The term has also adopted by climbers and backpackers to refer to a more solid. These vary from simple bothies – which are more than very basic shelters – to mountain huts that are far more luxurious. Apparently first in English as a military word, old Saxon hutta, Danish hytte, Swedish hytta, Frisian and Middle Dutch hutte, Dutch hut are from High German. Huts are used by shepherds when moving livestock between seasonal grazing areas such as mountainous and lowland pastures and they are also commonly used by backpackers and other travelers in rural areas. Some displaced populations of people use throughout the world during a diaspora. For example, temporary collectors in the agricultural workers at plantations in the Amazon jungle. Huts have been built for other than as a dwelling such as storage, workshops. Balok – A Siberian wilderness hut made of logs, usually communal, used by hunters, fishermen, some baloks are mobile and mounted on sleds. Bothy – Originally a one-room hut for men farm workers in the United Kingdom, burdei or bordei – a dugout or pit-house with a sod roof in Ukraine, Canada Cabana – an open shelter Chozo also spelled chozo – Spanish for hut, term also used in Mexico. Designed 1940 for barrack accommodation Lodge is a term for a hut or cabin such as a log cabin or cottage. Lodge is used to refer to a tipi, sweat lodge, and hunting, fishing, skiing, and safari lodge. Mitato – A small, dry stone hut in Greece Orri – A French dry stone, rondavel – Central and South Africa Sheiling – Originally a temporary shelter or hut for shepherds, now may be a stone building. Sod house – A pioneer house type on the American Plains where wood was scarce, construction often does not require specialized tools or knowledge. Hut is used to name commercial stores, companies, and concepts, the name implies a small, casual venue, often with a fun and friendly atmosphere

Defensive wall
–
A defensive wall is a fortification used to protect a city, town or other settlement from potential aggressors. In ancient to modern times, they were used to enclose settlements, beyond their defensive utility, many walls also had important symbolic functions – representing the status and independence of the communities they embraced. Existing ancient walls are almost always masonry structures, although brick, depending on the topography of the area surrounding the city or the settlement the wall is intended to protect, elements of the terrain may be incorporated in order to make the wall more effective. Walls may only be crossed by entering the city gate and are often supplemented with towers. Simpler defensive walls of earth or stone, thrown up around hillforts, ringworks, early castles, from very early history to modern times, walls have been a near necessity for every city. Uruk in ancient Sumer is one of the worlds oldest known walled cities, before that, the city of Jericho in what is now the West Bank had a wall surrounding it as early as the 8th millennium BC. The Assyrians deployed large labour forces to build new palaces, temples, some settlements in the Indus Valley Civilization were also fortified. By about 3500 B. C. hundreds of small farming villages dotted the Indus floodplain, many of these settlements had fortifications and planned streets. Mundigak in present-day south-east Afghanistan has defensive walls and square bastions of sun dried bricks, babylon was one of the most famous cities of the ancient world, especially as a result of the building program of Nebuchadnezzar, who expanded the walls and built the Ishtar Gate. Exceptions were few — notably, ancient Sparta and ancient Rome did not have walls for a long time, initially, these fortifications were simple constructions of wood and earth, which were later replaced by mixed constructions of stones piled on top of each other without mortar. In Central Europe, the Celts built large fortified settlements which the Romans called oppida, the fortifications were continuously expanded and improved. In ancient Greece, large stone walls had been built in Mycenaean Greece, in classical era Greece, the city of Athens built a long set of parallel stone walls called the Long Walls that reached their guarded seaport at Piraeus. Large tempered earth walls were built in ancient China since the Shang Dynasty, although stone walls were built in China during the Warring States, mass conversion to stone architecture did not begin in earnest until the Tang Dynasty. The large walls of Pingyao serve as one example, likewise, the famous walls of the Forbidden City in Beijing were established in the early 15th century by the Yongle Emperor. The Romans fortified their cities with massive, mortar-bound stone walls, the most famous of these are the largely extant Aurelian Walls of Rome and the Theodosian Walls of Constantinople, together with partial remains elsewhere. These are mostly city gates, like the Porta Nigra in Trier or Newport Arch in Lincoln, apart from these, the early Middle Ages also saw the creation of some towns built around castles. These cities were only protected by simple stone walls and more usually by a combination of both walls and ditches. From the 12th century AD hundreds of settlements of all sizes were founded all across Europe and these cities are easy to recognise due to their regular layout and large market spaces

Embrasure
–
In military architecture, an embrasure is the opening in a crenellation or battlement between the two raised solid portions or merlons, sometimes called a crenel or crenelle. In domestic architecture this refers to the outward splay of a window or arrow slit on the inside, a loophole, arrow loop or arrowslit passes through a solid wall and was originally for use by archers. The purpose of embrasures is to allow weapons to be fired out from the fortification while the remains under cover. The splay of the wall on the inside provides room for the soldier and his equipment, excellent examples of deep embrasures with arrow slits are to be seen at Aigues-Mortes and Château de Coucy, both in France. The etymology of embrasure expresses widening, the invention of the arrowslit is attributed to Archimedes during the siege of Syracuse in 214–212 BC. From Polybiuss The Histories, Archimedes had had the walls pierced with large numbers of loopholes at the height of a man, however, the invention was later forgotten until reintroduced in the 12th century. By the 19th century, a distinction was made between embrasures being used for cannon, and loopholes being used for musketry, in both cases, the opening was normally made wider on the inside of the wall than the outside. A distinction was made between horizontal and vertical embrasures or loopholes, depending on the orientation of the formed in the outside wall. Vertical loopholes—which are much more common—allow the weapon to be raised and lowered in elevation so as to cover a variety of ranges easily. However to sweep from side to side the weapon must bodily move from side to side to pivot around the muzzle, horizontal loopholes, on the other hand, facilitate quick sweeping across the arc in front, but make large adjustments in elevation very difficult. They were usually used in circumstances where the range was very restricted anyway, another variation had both horizontal and vertical slits arranged in the form of a cross, and was called a crosslet loop or an arbalestina since it was principally intended for arbalestiers. A series of perpendicular steps tapering to the gun port ensured that any incoming fire would be stopped by a vertical impact, arrowslit This article incorporates text from a publication now in the public domain, Chisholm, Hugh, ed. article name needed

Coastal artillery
–
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. The advent of 20th-century technologies, especially aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannon, battleships. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities, in littoral warfare, mobile coastal artillery armed with surface-to-surface missiles still can be used to deny the use of sea lanes. Land-based guns also benefited in most cases from the protection of walls or earth mounds. The Martello tower is an excellent example of a widely used coastal fort which mounted defensive artillery, during the 19th century China also built hundreds of coastal fortresses in an attempt to counter Western naval threats. Coastal artillery could be part of the Navy, or part of the Army, in English-speaking countries, certain coastal artillery positions were sometimes referred to as Land Batteries, distinguishing this form of artillery battery from for example floating batteries. In the United Kingdom, in the later 19th and earlier 20th Centuries, then, following the Spanish–American War and the report of the Endicott Board, U. S. harbor defenses were greatly strengthened and provided with new, rifled artillery and minefield defenses. Shortly thereafter, in 1907, Congress split the field artillery, the first decade of the 20th Century, the United States Marine Corps established the Advanced Base Force. The force was used for setting up and defending advanced bases, during the Siege of Port Arthur, Japanese forces had captured the vantage point on 203 Meter Hill overlooking Port Arthur harbor. The battleship Sevastopol, although hit 5 times by 11-inch shells, after 3 weeks, the Sevastopol was still afloat, having survived 124 torpedoes fired at her while sinking two Japanese destroyers and damaging six other vessels. The Japanese had meanwhile lost the cruiser Takasago to a mine outside the harbor, the Blücher had entered the narrow waters of the Oslofjord, carrying 1,000 soldiers and leading a German invasion fleet. The first salvo from the Norwegian defenders, fired from Oscarsborg Fortress about 1 mile distant, disabled Blüchers main battery, fire from the smaller guns swept her decks and disabled her steering, and she received several torpedo hits before the fires reached her magazines and doomed her. Singapore was defended by its famous large-caliber coastal guns, which included one battery of three 15-inch guns and one with two 15-inch guns, AP shells were designed to penetrate the hulls of heavily armoured warships and were ineffective against personnel. The Japanese defended the island of Betio in the Tarawa atoll with numerous 203 mm coastal guns, in 1943, these were knocked out early in the battle with a combined USN naval and aerial bombardment. Nazi Germany fortified its conquered territories with the Atlantic Wall, the intent was to destroy the Allied landing craft before they could unload. During the Normandy Landings in 1944, shore bombardment was given a high importance, using ships from battleships to destroyers, for example, the Canadians at Juno beach had fire support many times greater than they had had for the Dieppe Raid in 1942. In addition, there were modified landing-craft, eight Landing Craft Gun, twenty-four Landing Craft Tank carried Priest self-propelled howitzers which also fired while they were on the run-in to the beach. Similar arrangements existed at other beaches, on June 25,1944 the American battleship Texas engaged German shore batteries on the Cotentin Peninsula

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

Ironclad warship
–
An ironclad is a steam-propelled warship protected by iron or steel armor plates used in the early part of the second half of the 19th century. The ironclad was developed as a result of the vulnerability of warships to explosive or incendiary shells. The first ironclad battleship, Gloire, was launched by the French Navy in November 1859 and this type of ship would come to be very successful in the American Civil War. Ironclads were designed for several roles, including as high seas battleships, coastal defense ships and this change was pushed forward by the development of heavier naval guns, more sophisticated steam engines, and advances in metallurgy which made steel shipbuilding possible. The quick pace of change meant that ships were obsolete as soon as they were finished. Many ironclads were built to use of the ram or the torpedo. There is no end to the ironclad period, but towards the end of the 1890s the term ironclad dropped out of use. New ships were constructed to a standard pattern and designated battleships or armored cruisers. The ironclad became technically feasible and tactically necessary because of developments in shipbuilding in the first half of the 19th century. According to naval historian J. Richard Hill, The had three characteristics, a metal-skinned hull, steam propulsion and a main armament of guns capable of firing explosive shells. It is only when all three characteristics are present that a ship can properly be called an ironclad. Each of these developments was introduced separately in the decade before the first ironclads, in the 18th and early 19th centuries fleets had relied on two types of major warship, the ship of the line and the frigate. The first major change to these types was the introduction of power for propulsion. While paddle steamer warships had been used from the 1830s onwards, steam-powered screw frigates were built in the mid-1840s, and at the end of the decade the French Navy introduced steam power to its line of battle. The desire for change came from the ambition of Napoleon III to gain influence in Europe. The first purpose-built steam battleship was the 90-gun Napoléon in 1850, the introduction of the steam ship-of-the-line led to a building competition between France and Britain. Eight sister ships to Napoléon were built in France over a period of ten years, altogether, France built ten new wooden steam battleships and converted 28 from older ships of the line, while the United Kingdom built 18 and converted 41. The era of the wooden steam ship-of-the-line was brief, because of new, in the 1820s and 1830s, warships began to mount increasingly heavy guns, replacing 18- and 24-pounder guns with 32-pounders on sailing ships-of-the-line and introducing 68-pounders on steamers
