Following Cold Harbor, the corps was rushed to the Richmond-Petersburg area where it was engaged in the three-day Battle of Petersburg. The corps fought along the Confederate defensive works south of the Appomattox River during the Siege of Petersburg and over the next few months halted several of the Union offenses against the Confederate supply lines, such as at Jerusalem Plank Road, Ream's Station, and the Crater. Hill was ill several times during the siege, which forced him to turn operational control of the corps over to his division commanders, such as at Ream's Station. The corps lost several hundred men due to desertions during the winter.
