Map of battlefield core and study areas.
<p>The ABPP expanded the 1993 Study Area to include the Marsh Battery (location of the 200-pound Parrott gun known as "The Swamp Angel”), which bombarded Charleston in August 1863. The revised Study Area also includes the Confederate batteries on James Island, Sullivan’s Island, and Fort Sumter, as well as Charleston Harbor’s main shipping channel, which US naval forces used to enter Charleston Harbor from the Atlantic Ocean.

The revised Core Area includes the range of fire associated with “The Swamp Angel” bombardment in August 1863, as well as fire exchanged in September 1863 by the Confederate batteries on James Island, Sullivan’s Island, Fort Sumter, and the US fleet in Charleston Harbor.
