ww2dbaseCapitano Tarantini was launched in Jan 1940. She sank one ship, Panamanian tanker Beme, during her second war patrol on 11 Jul 1940. In Oct 1940, she arrived at the Italian submarine base Bordeaux Sommergibile (BETASOM) in Bordeaux, France. On her first mission out of Bordeaux, she survived a particularly long depth charge attack by Allied convoy escorts northwest of Ireland on 2 Dec 1940, but she would not be so lucky when discovered by British submarine HMS Thunderbolt in the Bay of Biscay on 15 Dec 1940, which sank her with a torpedo. Only five survived the sinking, including executive officer Lieutenant Attilio Frattura; Captain Alfredo Iaschi was lost. Her wreck was later found to be situated under 40 meters of water just off of the French coast.
