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. George Thomas's Army of the Cumberland, both in an east-west line north of the city along Peachtree Creek. Thomas had just crossed his army to the south bank of the creek and had not yet fully entrenched. Hood would attack using two of his three army corps, those of Gens. William J. Hardee and Alexander P. Stewart. Due to miscommunication of orders and lack of coordination between Hardee and Stewart, the attack did not begin until 4:00pm. Heavy fighting soon raged along both lines. Hardee had some success on the Union right, but was beaten back. Despite catching the Federals off guard, Hood's attacks were disjointed. The quick reacting Yankees were able to stave off their Confederate attackers and further secure their position around the strategic Confederate city. Hood would live to fight Thomas another day and Sherman would press on toward Atlanta.
