The High Water Mark (U.S. National Park Service)

Late in the afternoon, after a two-hour cannonade, some 7,000 Union soldiers posted around the Copse of Trees, The Angle, and the Brian Barn, repulsed the bulk of the 12,000-man “Pickett’s Charge” against the Federal center. This was the climactic moment of the battle. On July 4, Lee’s army began retreating.
