British sloop HMS Lulworth forced Italian submarine Pietro Calvi to surface south of the Azores islands with depth charges and proceeded to damage her with gunfire. The Italian crew scuttled the submarine. Elsewhere, German submarine U-562 fired four torpedoes at a small Allied convoy at the distance of 2,800 meters, but all torpedoes missed; she would continue to follow the convoy and conduct further attacks on the next day.
