Fort Moultrie left|thumb|The Moultrie Flag (also known as the Liberty Flag) being raised over Fort Moultrie, after the Patriot victory in the Battle of Sullivan's Island. On June 28, 1776, an incomplete fort was held by South Carolinian forces under Colonel William Moultrie against an invasion by a British force under the command of Henry Clinton sailing with Commodore Sir Peter Parker's Royal Navy fleet. The British cannonade proved to have no effect on the sand-filled palmetto log walls of the fort; the only fatalities were the result of those shots that carried over the walls.
