Fort Wagner

Fort Wagner or Battery Wagner was a beachhead fortification on Morris Island, South Carolina, that covered the southern approach to Charleston Harbor. It was the site of two American Civil War battles in the campaign known as Operations Against the Defenses of Charleston in 1863, and it is considered one of the toughest beachhead defenses constructed by the Confederate Army.

Named for deceased Lt. Col. Thomas M. Wagner, Fort Wagner measured 250 by 100 yards , and spanned an area between the Atlantic on the east and an impassable swamp on the west. Its walls, composed of sand and earth, rose 30 feet above the level beach and were supported by palmetto logs and sandbags. The fort's arsenal included fourteen cannons, the largest a 10-inch Columbiad that fired a 128-pound shell. It was a large structure capable of sheltering nearly 1,000 of the fort's 1,700-man garrison and provided substantial protection against naval shelling. The fort's land face was protected by a water-filled trench, 10 feet wide and 5 feet deep, surrounded by buried land mines and sharpened palmetto stakes. The fort itself was supported by defenses throughout Morris Island.
