Holding stage for slaves entering America.
Sullivan's Island was the disembarkation port for over 40% (ca. 200,000) of the slaves traded to the Britain's North American Colonies, making it the largest slave port in North America. It is estimated that nearly half of all African Americans had ancestors that passed through Sullivan's Island.
Slaves who spoke different languages were put together to minimise collaboration and resistance.
In December 1860 South Carolina seceded from the Union, and the Federal garrison abandoned Fort Moultrie for the stronger Sumter. Three and a half months later, Confederate troops shelled Sumter into submission, plunging the nation into civil war. In April 1863, Federal iron-clads and shore batteries began a 20-month bombardment of Sumter and Moultrie, yet Charleston’s defenses held. When the Confederate army evacuated the city in February 1865, Fort Sumter was little more than a pile of rubble and Fort Moultrie lay hidden under the band of sand that protected its walls from Federal shells. The new rifled cannon used during the Civil War had demolished the brick-walled fortifications.
