On June 28th

Fort Moultrie repelled the British fleet in June 1776; the Seminole leader Osceola died imprisoned there in 1838. The documented date is 1776-06-28–1838-01-30. Fort Moultrie on Sullivan’s Island's past is on record — the entry belongs to the verified layer the museum itself interprets. The record holds it as fact — documented, not retold. The detail is preserved in 'Fort Sumter National Monument'.

On June 28, 1776, Col. William Moultrie's palmetto-log fort on Sullivan's Island absorbed a nine-hour pounding by the British fleet — cannonballs sinking harmlessly into the spongy logs — and drove the fleet off. South Carolina still celebrates Carolina Day every June 28; the palmetto went onto the state flag, and the fort's low silhouette still guards the harbor mouth.
