Despite the defeat at Peach Tree Creek, Confederate Lieut. Gen. John Bell Hood still had hopes of driving Maj. Gen. William T. Sherman's armies from the outskirts of Atlanta with an offensive blow. On the evening of July 21, 1864, Hood ordered Lt. Gen. William J. Hardee's corps to make a 15-mile night march and assault the Union left flank east of the city, held by Maj. Gen. James B. McPherson's Army of the Tennessee. Supporting Hardee’s attack was the corps of Maj. Gen. Benjamin Cheatham. The next day, Hardee attacked McPherson's position from the south and Cheatham from the west. After initial Confederate success on the Union left, the heavy fighting shifted to the Union center and right. McPherson was killed during the battle, but the Union positions held. Fighting raged up and down the lines until after sunset. Despite initial successes, Hood's attacks failed to dislodge the Federals who strengthened their foothold on the doorstep of Atlanta.
