After marching all night, Hardee’s reinforced Confederate corps on Friday, July 22, 1864 struck the flank of McPherson’s Union forces east of Atlanta. A second Confederate corps under Benjamin Cheatham, facing eastward, guarded Hardee’s rear and flank and assisted in the attack on McPherson’s Federals. What the Confederates did not know was that two divisions of a Union corps had been ordered to extend McPherson’s flank during the preceding night, filling the very space which Hardee intended to mass and attack with his troops. Bitter fighting ensued with heavy casualties on both sides. Confederate General W.H.T. Walker was killed, as was Union General James McPherson. By nightfall the Confederates withdrew, once again unsuccessful in their efforts to defeat a portion of Sherman’s army which literally remained at the gates of Atlanta.
