3:30-5 p.m. "The Hopeless Charge: The Last Attacks at Marye's Heights." Union troops repeatedly attacked the Confederate heights, and hope dimmed with each failure. Only a few, like Gen. A.A. Humphreys, still believed they could win. Most Northerners continued to attack anyway--not to win, but to keep the Confederates from destroying their broken army. Meet at Hurkamp Park, Prince Edward and George streets.
