This pair of photos, modern and wartime, show ground occupied by the Union reserve during the battle, and the days immediately afterward. The caption of the historic view claimed to depict the Antietam Battlefield on the day of the battle. Although there is some question about the exact date the photograph was taken (see Frassanito, page 71), there is no doubt that the ground shown here is not part of the battlefield, but rather fields south of the Pry House, on the east side of the Antietam.
