On Friday last the British Frigate Perseus, Capt. Elphinstone, appeared off this Harbour, and chased several Vessels in. A Boat, with six American Prisoners, whom the Captain had set at Liberty, came ashore that Day to Fort Moultrie. The Perseus came to an Anchor near the Bar, but the Wind rising, put out to Sea at Night. Next morning she appeared off again, received six British Prisoners sent from hence, dismissed four more Americans, and of three Vessels coming in took two, viz. Capt. Newell in a Sloop from St. Thomas's, and a French Schooner.1 The Frigate has since disappeared, and it is said is gone to the West-Indies with her Prizes.
