Which of the following battles was a significant victory for the Confederacy during the Civil War in Georgia?

The Battle of Chickamauga was a significant victory for the Confederacy during the Civil War, particularly in Georgia. Fought from September 18 to 20, 1863, it was one of the largest battles in the Western Theater and marked a major Confederate victory against Union forces. The battle showcased the Confederate army's effectiveness and tactical prowess, as they were able to repel a Union advance into Georgia, which was a critical state for both strategic resources and as a supply line.

Chickamauga was crucial because it bolstered Southern morale and temporarily halted Union General William Rosecrans' offensive towards Chattanooga, Tennessee. This victory allowed the Confederacy to maintain control over northwestern Georgia for a period, illustrating the intense and pivotal nature of the conflict in that region during the war.

In contrast, battles such as Gettysburg and Antietam were significant Union victories that turned the tide of the war, while the Battle of Atlanta was part of General Sherman's campaign in 1864, which ultimately contributed to the downfall of the Confederacy rather than enhancing its position. Thus, Chickamauga stands out as a notable Confederate success during a pivotal time in the Civil War.
