The Master of a West-Indiaman, taken by an American privateer, and set on shore at Nantes, since arrived in London, gives the following account of the Thomas Koulikan, taken by the Hector man of war, Capt. Sir John Hamilton, and brought into Portsmouth: He says, that whilst he was at Nantes, waiting for remittances from England, the above ship was loading there with bale goods, hardware, stores of all kinds, and a quantity of gunpowder and shot. She is about 450 or 500 tons burthen, frigate-built, and had ports for 32 guns, 24 twelve pounders on the main deck, 6 pounders on the quarter-deck, and two on the forecastle; she then had no guns mounted, and he was told they were to be stowed in the hold till she arrived whither she was bound. A number of American Gentlemen were waiting to go out in her; among the rest an American supercargo, who had the care of her loading, and a Mr. Nicholson,1 who was to be Captain of her when they arrived in America: The manner of sending her out was only to avoid the French ordinance concerning military stores being sent to America, for which reason she was laid out for St. Domingo, and which Port they were to declare for if met with any King's ship, but as soon as opportunity offered make for any part of the Continent of America, in the hands of the Congress.—The above Nicholson has a brother at Baltimore, Commander of a large privateer,2 which has been blocked up some time by our frigates, cruizing off the Capes of Virginia; this Nicholson is called Commodore among the Provincials.
