On 21 October 1940 the submarine Sciré departed La Spezia and sailed to Gibraltar carrying three manned torpedoes and four crews. The Decima MAS frogmen, commanded by Birindelli, entered the harbour, but were unable to attack any ships due to technical problems with the torpedoes and breathing equipment. Only one human torpedo managed to get close to a target, the battleshipHMS Barham. The charge exploded but did not cause significant damage. The two crewmen, Birindelli and Damos Paccagnini, were captured by the British. The other four (including Teseo Tesei) managed to reach Spain and returned to Italy. Valuable experience was gained in this operation by the Decima. Gino Birindelli received the Medaglia d'Oro al Valor Militare (MOVM), his second, Damos Paccagnini received the Medaglia d'Argento al Valore Militare (MAVM).
He remained a prisoner of the Allies until he was repatriated in 1944. After his release, he fought with the Italian Co-belligerent Navy against the Germans.[2]
After the war
After the war Birindelli was made Commander of Italian marines Comando Raggruppamento Subacquei e Incursori Teseo Tesei in 1952. In 1956 he was the commander of the cruiserRaimondo Montecuccoli. He was promoted to rear admiral in 1959, admiral in 1962 and fleet admiral in 1966. In 1969, he became chief of fleet, overseeing all operational units of the Italian Navy. In 1970 he became chief of Mediterranean Command of the NATO Fleet in Malta (he would be dismissed the following year by Dom Mintoff's Labour Party government, which declared him persona non grata within a day from the new cabinet's swearing-in)[3] and commander in chief NATO naval forces in southern Europe.[4]
In 1972 Giorgio Almirante, leader of the Italian Social Movement, added establishment figures such as admiral Birindelli as members.[5] Birindelli was president of the party from 1972-1973. He served in the Italian Parliament between 1972 and 1976, with MSI-DN.[6]
