Confederate Infantryman – Confederate States of America CSA, 1864

The Confederate States Army, also called the Confederate Army or the Southern Army, was the military land force of the Confederate States of America (commonly referred to as the Confederacy) during the American Civil War (1861–1865), fighting against the United States forces in order to win the independence of the Southern states and uphold the institution of slavery. 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 newly chosen Confederate president, Jefferson Davis. Davis was a graduate of the U.S. Military Academy, and colonel of a volunteer regiment during the Mexican–American War. He had also been a United States senator from Mississippi and U.S. Secretary of War under President Franklin Pierce. On March 1, 1861, on behalf of the Confederate government, Davis assumed control of the military situation at Charleston, South Carolina, where South Carolina state militia besieged Fort Sumter in Charleston harbor, held by a small U.S. Army garrison. By March 1861, the Provisional Confederate Congress expanded the provisional forces and established a more permanent Confederate States Army.

An accurate count of the total number of individuals who served in the Confederate Army is not possible due to incomplete and destroyed Confederate records; estimates of the number of individual Confederate soldiers are between 750,000 and 1,000,000 troops. This does not include an unknown number of slaves who were pressed into performing various tasks for the army, such as the construction of fortifications and defenses or driving wagons. Since these figures include estimates of the total number of individual soldiers who served at any time during the war, they do not represent the size of the army at any given date. These numbers do not include sailors who served in Confederate States Navy.
