Dug Gap was so named because a pioneer road, cut out of the hillside, passed through a cleft in Rocky Face Ridge at this point.
The road led east to Dalton and the Western and Atlantic Railroad, important military objectives. Federals sought in February and again in May, 1864, to pass thought the gap but were repulsed.
May 8, 1864 as the Atlanta Campaign began, Geary´s Division of the Federal Twentieth Corps attacked Dug Gap, but was driven back after a brisk action. Direct attacks on Dalton failing, Sherman flanked toward Resaca thought the broken, wooded area to the west.
