Lt. Col. Washington led his Calvary around the east side of the battlefield, then rode into the British rear at the base of Hobkirk's Hill. There he found a large number of stragglers, wounded men, doctors, and other noncombatants.
Washington took as many as 200 prisoners, granting most of them parole - released on their promise not to fight again until exchanged.
"Part of the Enemy's Calvary got into our rear, exacted paroles from several Officers who lay wounded ? & carried off several Wounded Men." Lord Rawdon
Washington was so busy dealing with the captives that he failed to follow Greene's order to make an immediate attack on the rear of the British battle line.
By the time Washington finished issuing paroles, the Americans had been driven from the hill. He returned to the main army, bringing back fifty prisoners.
