The U.S. Army is headed by a civilian senior appointed civil servant, the Secretary of the Army (SECARMY), and by a chief military officer, the Chief of Staff of the Army (CSA) who is also a member of the Joint Chiefs of Staff. In the fiscal year 2016, the projected end strength for the Regular Army (USA) was 475,000 soldiers; the Army National Guard (ARNG) had 342,000 soldiers, and the United States Army Reserve (USAR) had 198,000 soldiers; the combined-component strength of the U.S. Army was 1,015,000 soldiers.

Hunley demonstrated the advantages and the dangers of undersea warfare. She was the first combat submarine to sink a warship (USS Housatonic), although Hunley was not completely submerged and, following her successful attack, was lost along with her crew before she could return to base. The Confederacy lost 21 crewmen in three sinkings of Hunley during her short career. She was named for her inventor, Horace Lawson Hunley, shortly after she was taken into government service under the control of the Confederate States Army at Charleston, South Carolina.

paragraph_text: After the war, though, the Continental Army was quickly given land certificates and disbanded in a reflection of the republican distrust of standing armies. State militias became the new nation's sole ground army, with the exception of a regiment to guard the Western Frontier and one battery of artillery guarding West Point's arsenal. However, because of continuing conflict with Native Americans, it was soon realized that it was necessary to field a trained standing army. The Regular Army was at first very small, and after General St. Clair's defeat at the Battle of the Wabash, the Regular Army was reorganized as the Legion of the United States, which was established in 1791 and renamed the "United States Army" in 1796.

paragraph_text: The English name Switzerland is a compound containing Switzer, an obsolete term for the Swiss, which was in use during the 16th to 19th centuries. The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, one of the Waldstätten cantons which formed the nucleus of the Old Swiss Confederacy. The name originates as an exonym, applied pars pro toto to the troops of the Confederacy. The Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for "Confederates", Eidgenossen (literally: comrades by oath), used since the 14th century.

paragraph_text: In North America, there was significant tension between New France and the northern English colonies, which had in 1686 been united in the Dominion of New England. New England and the Iroquois Confederacy fought New France and the Wabanaki Confederacy. The Iroquois dominated the economically important Great Lakes fur trade and had been in conflict with New France since 1680. At the urging of New England, the Iroquois interrupted the trade between New France and the western tribes. In retaliation, New France raided Seneca lands of western New York. In turn, New England supported the Iroquois in attacking New France, which they did by raiding Lachine.There were similar tensions on the border between New England and Acadia, which New France defined as the Kennebec River in southern Maine. English settlers from Massachusetts (whose charter included the Maine area) had expanded their settlements into Acadia. To secure New France's claim to present-day Maine, New France established Catholic missions among the three largest native villages in the region: one on the Kennebec River (Norridgewock); one further north on the Penobscot River (Penobscot) and one on the Saint John River (Medoctec). For their part, in response to King Philip's War, the five Indian tribes in the region of Acadia created the Wabanaki Confederacy to form a political and military alliance with New France to stop the New England expansion.

paragraph_text: The government of the United States (the Union) rejected the claims of secession and considered the Confederacy illegally founded. The War began with the Confederate attack upon Fort Sumter on April 12, 1861, a Union fort in the harbor of Charleston, South Carolina. No foreign government officially recognized the Confederacy as an independent country, although Great Britain and France granted it belligerent status, which allowed Confederate agents to contract with private concerns for arms and other supplies. In early 1865, after four years of heavy fighting which led to 620,000–850,000 military deaths, all the Confederate forces surrendered and the Confederacy vanished. The war lacked a formal end; nearly all Confederate forces had been forced into surrender or deliberately disbanded by the end of 1865, by which point the dwindling manpower and resources of the Confederacy were facing overwhelming odds. By 1865 Jefferson Davis, the President of the Confederate States of America for the duration of the civil war, lamented that the Confederacy had "disappeared".

paragraph_text: The Battle of Peachtree Creek was fought in Georgia on July 20, 1864, as part of the Atlanta Campaign in the American Civil War. It was the first major attack by Lt. Gen. John Bell Hood since taking command of the Confederate Army of Tennessee. The attack was against Maj. Gen. William T. Sherman's Union army which was perched on the doorstep of Atlanta. The main armies in the conflict were the Union Army of the Cumberland, commanded by Maj. Gen. George Henry Thomas and two corps of the Confederate Army of Tennessee.

The last was Florence Green (1901–2012), who was not identified as a veteran of the conflict until January 2010. This meant that Campany was believed to be the conflict's last surviving female veteran by the time of her death in December 2008.

paragraph_text: Sherman's March to the Sea (also known as the Savannah Campaign) was a military campaign of the American Civil War conducted through Georgia from November 15 until December 21, 1864, by Maj. Gen. William Tecumseh Sherman of the Union Army. The campaign began with Sherman's troops leaving the captured city of Atlanta on November 15 and ended with the capture of the port of Savannah on December 21. His forces followed a ``scorched earth ''policy, destroying military targets as well as industry, infrastructure, and civilian property and disrupting the Confederacy's economy and its transportation networks. The operation broke the back of the Confederacy and helped lead to its eventual surrender. Sherman's bold move of operating deep within enemy territory and without supply lines is considered to be one of the major achievements of the war.

paragraph_text: The conflict is known by multiple names. In British America, wars were often named after the sitting British monarch, such as King William's War or Queen Anne's War. As there had already been a King George's War in the 1740s, British colonists named the second war in King George's reign after their opponents, and it became known as the French and Indian War. This traditional name continues as the standard in the United States, but it obscures the fact that Indians fought on both sides of the conflict, and that this was part of the Seven Years' War, a much larger conflict between France and Great Britain. American historians generally use the traditional name or sometimes the Seven Years' War. Other, less frequently used names for the war include the Fourth Intercolonial War and the Great War for the Empire.

paragraph_text: The Posey War, also known as the Last Indian Uprising and several other names, occurred in March 1923 and may be considered the final Indian War in American history. Though it was a minor conflict, it involved a mass exodus of Ute and Paiute native Americans from their land around Bluff, Utah to the deserts of Navajo Mountain. The natives were led by a chief named Posey, who took his people into the mountains to try and escape his pursuers. Unlike previous conflicts, posses played a major role while the United States Army played a minor one. The war ended after a skirmish at Comb Ridge. Posey was badly wounded and his band was taken to a prisoner-of-war camp in Blanding. When Posey's death was confirmed by the authorities, the prisoners were released and given land allotments to farm and raise livestock.

paragraph_text: Confederate troops from all parts of North Carolina served in virtually all the major battles of the Army of Northern Virginia, the Confederacy's most famous army. The largest battle fought in North Carolina was at Bentonville, which was a futile attempt by Confederate General Joseph Johnston to slow Union General William Tecumseh Sherman's advance through the Carolinas in the spring of 1865. In April 1865, after losing the Battle of Morrisville, Johnston surrendered to Sherman at Bennett Place, in what is today Durham. North Carolina's port city of Wilmington was the last Confederate port to fall to the Union, in February 1865, after the Union won the nearby Second Battle of Fort Fisher, its major defense downriver.

paragraph_text: The First Day of the Battle of Gettysburg during the American Civil War took place on July 1, 1863, and began as an engagement between isolated units of the Army of Northern Virginia under Confederate General Robert E. Lee and the Army of the Potomac under Union Maj. Gen. George G. Meade. It soon escalated into a major battle which culminated in the outnumbered and defeated Union forces retreating to the high ground south of Gettysburg, Pennsylvania.

paragraph_text: The Lorenz rifle was the third most widely used rifle during the American Civil War. The Union recorded purchases of 226,924 and the Confederacy bought as many as 100,000. Confederate-bought Lorenz rifles saw heavy use in the Army of Tennessee in 1863-64, with many of them being issued to re-equip regiments captured at the siege of Vicksburg and later exchanged. On the Union side, continental European firearms were mostly distributed to the Western armies--as such, the Lorenz Rifle was relatively uncommon in the Army of the Potomac (although two regiments of the famous Iron Brigade carried them) but heavily used by the Army of the Cumberland and Army of the Tennessee.
