 On May 16, the regiment was engaged at the Battle of Proctor's Creek (alternately Drewry's Bluff or Fort Darling).After a brave defense of their position, much of the regiment was surrounded while fighting in a dense fog, losing in addition to its killed and wounded, 252 of its number taken prisoners.Among the captured were the colonel, lieutenant colonel, and General Heckman; some 120 would later die in prison suffering appalling conditions at Andersonville.
