The Years of War

On January 18, 1861, Georgia seceded from the Union during the American Civil War but kept the name "State of Georgia", and joined the newly formed Confederacy in February. During the war, Georgia sent nearly 100,000 soldiers to battle, mostly to the armies in Virginia. The state switched from cotton to food production, but severe transportation difficulties eventually restricted supplies. Early in the war, the state's 1,400 miles of railroad tracks provided a frequently used means of moving supplies and men but, by the middle of 1864, much of these lay in ruins or in Union hands.
Thinking the state safe from invasion, the Confederates built several small munitions factories in Georgia, as well as housing tens of thousands of Union prisoners. Their largest prisoner of war camp, at Andersonville, proved a death camp because of severe lack of supplies, food, water, and medicine.
  During the Civil War lots of battles took place in this state. Georgia was relatively free from war until late 1863. A total of nearly 550 battles and skirmishes occurred within the state, with the vast majority in the last two years of the conflict. The first major battle in Georgia was a Confederate victory at the Battle of Chickamauga in 1863—it was the last major Confederate victory in the west. In 1864 William T. Sherman's armies invaded Georgia as part of the Atlanta Campaign. Confederate general Joseph E. Johnston fought a series of delaying battles, the largest being the Battle of Kennesaw Mountain, trying to delay Union armies for as long as possible as he retreated toward Atlanta. Johnston's replacement, Gen. John Bell Hood, attempted several unsuccessful counterattacks at the Battle of Peachtree Creek and the Battle of Atlanta, but Sherman captured Atlanta on September 2, 1864.
