She then sank seven ships and damaged two more – all in March. One of them, "E. M. Clark", was hit in such a way that her whistle sounded continuously until the ship went down. Another, "Esso Nashville", was hit by a torpedo which failed to detonate, but a subsequent torpedo broke the tanker's back. She was held together only by deck plates and piping. The bow and stern sections soon separated, and the bow soon sank. The stern was towed to Baltimore where it was fitted with a new fore-part and the ship returned to service in March 1943.
