In May 1864, Union general William T. Sherman began his invasion of Georgia, going up against Confederate general Joseph Johnston in a series of battles and skirmishes throughout early and mid-summer. But in July, President Jefferson Davis, unhappy with Johnston’s tactics, replaced him with the more aggressive John Bell Hood.
Sherman’s and Hood’s men clashed time and again in July and August. Sherman, unwilling to attempt a head-on assault of Atlanta, decided instead to cut off the city’s last remaining railroad supply line, which his men successfully did despite Confederate opposition.
When Hood was informed of the rail line’s destruction, he ordered the evacuation of his men from Atlanta on September 1. Before they left, they destroyed ammunition stores, locomotives, and anything else the Federals would find useful. The Federals took the city the next day. Sherman’s troops would remain in Atlanta for another two months, before leaving in mid-November on Sherman’s destructive March to the Sea.
