After Italy signed the Armistice of Cassibile in September 1943, "Euro" participated in the Battle of Leros where she was sunk by German Junkers Ju 87 "Stuka" dive bombers during an air raid on 3 October 1943. "Turbine" was seized by the "Kriegsmarine" and put into service in the Aegean Sea as a torpedo boat. On 19 June 1944, at Porto Lago, she was badly damaged by an explosion, which was thought to have been sabotage. She set in to the port of Salamis for repairs, but a US air strike on the port on 16 September sank her before they could be entirely completed.
