Battle - Peachtree Creek - Fulton County, Georgia
Weary of Gen. Joseph E. Johnston's pattern of retreat through northwest Georgia in the face of Maj. Gen. William T. Sherman's advancing armies, President Jefferson Davis removed him from command of the Army of Tennessee, replacing him with Lieut. Gen. John B. Hood. On July 20th, Hood determined to take the fight to the enemy by setting upon an isolated portion of Sherman's forces in front of Atlanta. Hood's target would be the Union corps of Maj. Gens. Oliver O. Howard and Joseph Hooker from Maj. Gen. Geo…READ MORE

By late August 1865, the city of Atlanta was not yet subdued by Maj. Gen. William T. Sherman's armies. A few supply lines remained open to the city supporting the army of Lieut. Gen. John B. Hood encircled there. Union cavalry raids inflicted only superficial damage, quickly repaired by the Confederates. Sherman determined that if he could destroy the Macon & Western and Atlanta & West Point Railroads to the south the Rebel army would be forced to evacuate the city.
