Operation Ironclad
On 5 May 1942, the submarine was taken by surprise during the preliminary bombardments which began the Battle of Madagascar. She quickly put to sea with two thirds of her crew at 0600. Three Fairey Swordfish fired on the boat, which changed course to evade attack. She came under continued attack, which damaged the boat's hull. One of the three Swordfish managed to dismount "Bévéziers"s machine gun, causing the disappearance of two of the crew and the wounding of four more. The submarine then sank.
