| On 15th October 1940, the Italian submarine Enrico Toto (C.C. Bandino Bandini) encountered HMS Traid south west of Calabria in position 38°16'N, 17°37'E. The Submarines passed at close range on opposite courses as the Italian submarine engaged with machine-gun fire and three rounds of 4" from her deck gun, claiming two direct hits. HMS Triad fired back scoring a hit on the conning tower of Enrico Toti but this caused only slight damage and wounded two sailors. Triad’s torpedo missed the Italian submarine by a few yards. Triad pulled away and dived but Enrico Toti had fired a torpedo which made a direct hit. Triad was lost with all hands. | |
A highly illustrated history of the Cold War operations of the submarines of the Royal Navy from 1948 to 1990.
The Cold War was a period of intense activity for submarines of the Royal Navy, with many hair-raising incidents involving Soviet vessels. They were engaged in frequent hazardous surveillance patrols investigating Soviet submarines and surface warships and their operational tactics, and trailing Soviet strategic submarines (SSBNs), as well as conducting British deterrent SSBN patrols and protecting those patrols using attack submarines (SSNs).
There were also dangerous patrols which trialled submarine operation under the Arctic ice-cap. In addition to these activities there were operations in other conflicts and war theatres including the Falklands War, the Suez campaign, the Northern Ireland Troubles, and the Indonesian confrontation.
