During her time in the Mediterranean, she sank the Italian merchants "Edda" and "Bologna" (the former French "Monaco"), the Italian pilot vessel F 20 / "Enrica", and the Italian auxiliary minesweeper No. 17/"Milano". She also damaged the Italian sailing vessel "Vale Formoso II", the German (former Norwegian) tanker "Regina", and most significantly, the Italian heavy cruiser "Bolzano" and the Italian light cruiser "Muzio Attendolo" during Operation Pedestal. "Bolzano" was hit in her oil tanks and set ablaze; she had to be beached at Panarea island; the "Attendolo" lost sixty feet of bow. "Bolzano" was out of action for the rest of the war.
