Last Week arrived at a neighbouring Port1 the Providence Sloop of War, of 12 Guns, in the Service of the United States, John Rathbun, Esq; Commander. About a Month since Capt. Rathbun entered the Harbour of New-Providence, in the Night, where he landed 30 Men, 15 of which scaled the Walls of the Fort,2 by means of Rope-Ladders, and got Possession, where they found only one Centinel; the Remainder of the Party possessed themselves of Hog Island, opposite the Town.3 The Inhabitants were informed next Morning, by a Flag, that their Property would be safe, provided no Attempt was made against the Sloop or her Crew. The same Day the Sloop was driven to Sea by a Gale of Wind, and remained out 16 Hours. On her Return Capt. Rathbun took Possession of a large Ship from Jamaica: bound to New-York, richly laden, mounting 16 Six and Four Pounders, that had put in there to stop a Leak. A Privateer from Jamaica,5 mounting 16 Guns, which had sent several Prizes to New-Providence, arrived in the Harbour, but on receiving a few Shot from the Sloop, she immediately weighed, and went round to another Part of the Island, where her Guns were landed, and placed before the Governor's House. Capt. Rathbun afterwards released 30 Americans from Prison, took about the same Number of British, and burnt a Sloop and Schooner that had been camed in there; he also took Possession of three sloops,6 one of them with a valuable Cargo of Indico and Rice, that had been cap tured by the Privateer above mentioned. After wooding and watering the Sloop and her Prizes, spilung the Guns in the Fort, and taking out a Quantity of military Stores, Capt. Rathbun quitted the Island, having remained there three Days, and arrived safe in Port in Company with the Ship. One of the Sloops is also amved.
