At dawn on May 8, Fitzhugh Lee's cavalrymen staked out a defensive line on a low ridge that they dubbed "Laurel Hill." Reinforcements from Anderson arrived just as Warren's men pulled up within 100 yards to the north. Assuming only cavalry blocked his path, Warren ordered an immediate attack. Multiple attacks by the divisions of the V Corps were repulsed with heavy casualties. In the afternoon, Sedgwick's VI Corps arrived near Laurel Hill and extended Warren's line to the east. By 7 p.m., both corps began a coordinated assault but were repulsed by heavy fire. They attempted to move around Anderson's right flank, but were surprised to find that divisions from Ewell's Second Corps had arrived in that sector to repulse them again.
