After the battle, Hill's corps was the first to start the Confederate retreat back to Virginia. Heth's division served as the rear guard as the army marched over the Potomac on July 14th; during the Battle of Falling Waters, Pettigrew was mortally wounded during a Union cavalry charge. During the fall, Cadmus Wilcox was promoted to major general and given command of Pender's former division. In the Battle of Bristoe Station, Hill attacked the isolated Union II Corps with only two brigades from his three available divisions, but was in turn hit in the flank by the awaiting V Corps. Hill lost heavily, 2,000 men in total along with five cannons. The corps also participated in the Mine Run Campaign; Hill was to assault the Union left flank at dawn on December 1, but the Union army retreated during the night. For the rest of the winter, the corps remained in winter camps south of the Rappahannock River.
