A few nights since, between 3 and 400 troops, from the State of Rhode Island, crossed the sound, and landed on Long-Island, near Setalket, where they engaged a party of the troops newly inlisted into Gen. Howe's army, commanded by one Smith; five or six of his men were killed in the action, and himself and 23 of his company made prisoners, who were brought off, with 75 excellent muskets. The prisoners are a motly herd, about one half of them being Negroes and Indians. Of the Rhode-Island troops, one was kill'd, and one wounded.
