Given the question: Information: - 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 massive 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. - In the military sciences, the term military campaign applies to large scale, long duration, significant military strategy plan incorporating a series of inter-related military operations or battles forming a distinct part of a larger conflict often called a war. The term derives from the plain of Campania, a place of annual wartime operations by the armies of the Roman Republic. - Cavalry (from French "cavalerie", cf. "cheval" 'horse') or horsemen were soldiers or warriors who fought mounted on horseback. Cavalry were historically the most mobile of the combat arms. An individual soldier in the cavalry is known by a number of designations such as cavalryman, horseman, dragoon or trooper. The designation of cavalry was not usually given to any military forces that used other animals, such as camels, mules or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the 17th and early 18th centuries as dragoons, a class of mounted infantry which later evolved into cavalry proper while retaining their historic title. - The Army of Tennessee was the principal Confederate army operating between the Appalachian Mountains and the Mississippi River during the American Civil War. It was formed in late 1862 and fought until the end of the war in 1865, participating in most of the significant battles in the Western Theater. It should not be confused with the Union Army of the Tennessee, named after the Tennessee River. - The PhilippineAmerican War (also referred to as the Filipino-American War, the Philippine War, the Philippine Insurrection, the Tagalog Insurgency; Spanish: "Guerra Filipino-Estadounidense"; Filipino: "Digmaang Pilipino-Amerikano") was an armed conflict between the First Philippine Republic (Spanish: "Republica Filipina") and the United States that lasted from February 4, 1899 to July 2, 1902.

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 destroyed military targets as well as industry, infrastructure, and civilian property and disrupted the Confederacy's economy and its transportation networks. 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. - A civil war, also known as an intrastate war in polemology, is a war between organized groups within the same state or country, or, less commonly, between two countries created from a formerly united state. The aim of one side may be to take control of the country or a region, to achieve independence for a region or to change government policies. The term is a calque of the Latin "bellum civile" which was used to refer to the various civil wars of the Roman Republic in the 1st century BC. - Joseph "Fighting Joe" Wheeler (September 10, 1836 January 25, 1906) was an American military commander and politician. He has the rare distinction of serving as a general during wartime for two opposing forces: first as a noted cavalry general in the Confederate States Army in the 1860s during the American Civil War, and later as a general in the United States Army during both the SpanishAmerican War and PhilippineAmerican War near the turn of the twentieth century. For much of the Civil War he served as the senior cavalry general in the Army of Tennessee and fought in most of its battles in the Western Theater. - The American Civil War was a civil war in the United States fought from 1861 to 1865.

Hostilities began in the aftermath of the internal explosion of the USS "Maine" in Havana harbor in Cuba leading to United States intervention in the Cuban War of Independence. American acquisition of Spain's Pacific possessions led to its involvement in the Philippine Revolution and ultimately in the PhilippineAmerican War. - The Confederate States Army (CSA) was the military ground force of the Confederate States (C.S.), also known as the "Confederacy", while the Confederacy existed during the American Civil War. On February 28, 1861, the Provisional Confederate Congress established a provisional volunteer army and gave control over military operations and authority for mustering state forces and volunteers to the Confederate president, Jefferson Davis, a graduate of the U.S. Military Academy and colonel of a volunteer regiment during the Mexican War. In March 1861, the Provisional Confederate Congress established a more permanent Confederate States Army. - Secession (derived from the Latin term "secessio") is the withdrawal of a group from a larger entity, especially a political entity (a country), but also any organization, union or military alliance. Threats of secession can also be a strategy for achieving more limited goals. - William Tecumseh Sherman (February 8, 1820 February 14, 1891) was an American soldier, businessman, educator and author. He served as a General in the Union Army during the American Civil War (186165), for which he received recognition for his outstanding command of military strategy as well as criticism for the harshness of the "scorched earth" policies that he implemented in conducting total war against the Confederate States. - The Battle of Buck Head Creek ( also known as Buckhead Creek and Reynolds ' Plantation ) was the second battle of Sherman 's March to the Sea , fought November 28 , 1864 , during the American Civil War .

It was originally formed by seven slave states South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas in the Lower South region of the United States whose regional economy was mostly dependent upon agriculture, particularly cotton, and a plantation system that relied upon the labor of African-American slaves. - The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States and is designated as the Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (17751783)before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.
