The Battle of Atlanta took place during the Atlanta campaign of the American Civil War on July 22, 1864, just southeast of Atlanta, Georgia. Continuing their summer campaign to seize the important rail and supply hub of Atlanta, Union forces commanded by William T. Sherman overwhelmed and defeated Confederate forces defending the city under John B. Hood. Union Major General James B. McPherson was killed during the battle, the second-highest-ranking Union officer killed in action during the war. Despite the implication of finality in its name, the battle occurred midway through the Atlanta campaign, and the city did not fall until September 2, 1864, after a Union siege and various attempts to seize railroads and supply lines leading to Atlanta. After taking the city, Sherman's troops headed south-southeastward toward Milledgeville, the state capital, and on to Savannah with the March to the Sea.
