The Siege of Atlanta was a significant military campaign during the American Civil War, occurring from July 22 to September 2, 1864. It involved Union forces, led by General William Tecumseh Sherman, besieging the Confederate city of Atlanta, Georgia. The siege aimed to cut off supplies and force the Confederate army, commanded by General John Bell Hood, to surrender. The Union's successful siege resulted in the capture of Atlanta, a vital transportation hub for the Confederacy. This victory boosted Northern morale and helped secure President Abraham Lincoln's re-election. The fall of Atlanta marked a turning point in the war, leading to further Union advances in the South.
