Artillery defenses of Charleston Harbor

Charleston Harbor was ringed by forts and batteries and became the scene of a long siege from 1863. Heavy rifled siege guns, including the Parrott known as the Swamp Angel, bombarded the works and the city.

Also known as: siege of Charleston.

A ring of guns

Charleston's defenses formed one of the strongest concentrations of coastal artillery in the Confederacy, with Fort Sumter at the center supported by Fort Moultrie, Battery Wagner, Fort Johnson, and numerous other works and batteries. Federal forces besieging the harbor from 1863 answered with heavy rifled siege artillery emplaced on the surrounding islands.

Among these guns was the Swamp Angel, a large Parrott rifle mounted in the marsh that shelled the city itself at long range before it burst. The prolonged bombardments reduced Fort Sumter to rubble, yet Charleston held until early 1865.
