The Floyds settled at Walnut Hill Plantation on the north side of Fish Haul Creek. During the American Revolutionary War in South Carolina, Charles was a member of the First Council of Safety. These men who favored independence raised a volunteer militia, the St. Helena Guards, whose hats bore a silver crescent with their motto, "Liberty or Death". In 1781, Charles Floyd, along with several others, all members of a war party called the "Bloody Legion," avenged the death of Revolutionary War hero, Charles Davant, by a Tory. Charles Davant had married Elizabeth Fendin (Bland) who was sister to Mary Fendin, so he was Charles Floyd's brother-in-law. Captain Floyd distinguished himself in forays against the British and their colonial policies. In reprisal, Tories plundered and burned the Floyd family home, but teenaged John Floyd survived, as did his mother.
