This vintage illustrated poster depicts the Battle of Atlanta and the death of General James B. McPherson, July 22nd 1864.

The Battle of Atlanta (also known as the Battle of Decatur) was a battle of the Atlanta Campaign fought during the American Civil War on July 22, 1864, just southeast of Atlanta, Georgia. Continuing their summer campaign to seize the important rail and supply center of Atlanta, Union forces overwhelmed and defeated Confederate forces defending the city. Despite the implication of finality in its name, the battle occurred mid-way through the campaign and the city would not fall for another six weeks.
