During the Battle of North Anna, the Third Corps was positioned on the Confederate left. On May 23rd, Wilcox's division attacked the V Corps as it was crossing the North Anna near Jericho Mill; faulty intelligence had led him to believe that only two Union cavalry brigades had crossed the river. Wilcox launched his attack about 6 p.m. and initially routed two Union brigades but was driven back by a Union counterattack before Confederate reinforcements arrived. Wilcox lost 730 men while inflicting only 338 casualties on the Union forces. During the rest of the battle, the corps was engaged in only brief skirmishing. At Cold Harbor, Hill was stationed on the Confederate left flank but on June 2 Mahone's and Wilcox's divisions were moved to the Confederate right in response to the movements of the Union II Corps; Heth's division remained on the left. On June 3rd, an attack by the Union II Corps briefly overran part of the Confederate line to Hill's left but the Florida Brigade counterattacked an recaptured the line.
