Originally placed behind a hill to the rear, the 22nd Virginia Infantry was moved in front of the Confederate artillery, where it overlooked the highway. Companies A, E, and I were later detached and sent to reinforce Col. Jackson on the left flank. Both groups were overrun by Federal troops, and the 22nd suffered some of the heaviest casualties in the battle. The regiment entered the fight with 550 men, of whom 113 were killed, wounded, or missing, including 15 of 24 officers. Its commander, Col. George S. Patton, had organized the regiment in Charleston, then part of Virginia, at the beginning of the war, and he was the grandfather of General Patton of World War II fame.
