A British Chariot manned torpedo

Operation Title was an unsuccessful 1942 Allied attack on the German battleship Tirpitz during World War II. The Allies considered Tirpitz to be a major threat to their shipping and after several Royal Air Force heavy bomber raids failed to inflict any damage it was decided to use Royal Navy midget submarines instead. Operation Title involved a pair of two-man British Chariot manned torpedoes which were transported to Norway on board a small boat named Arthur. Both Chariots were lost when bad weather caused them to detach from Arthur on 31 October. It was not possible for the Allied boat to reach the sea due to German security measures, and Arthur was scuttled. The Allied personnel attempted to escape overland and all but one reached neutral Sweden on 5 November. The other – a British serviceman – was taken prisoner by German forces and murdered on 19 January 1943. Tirpitz was eventually sunk by another bomber raid on 12 November 1944. (Full article...)
