Rupert Lonsdale had the unhappy distinction of being the only British warship captain to have surrendered his ship to the enemy in the Second World War.
A special group of navy divers is created when a disabled Nazi warship is discovered in a fjord in Norway. Commander Bolton (James Caan) is the Canadian expert designated to train the new unit. Their mission is to plant a bomb on the warship as it undergoes repairs. The hard-driving Bolton encounters resentment from the British soldiers he trains, but he ultimately earns their respect as a leader. Their intense training operation is interrupted by an attack of Nazi paratroopers just before the unit leaves for Norway. Spectacular underwater photography is seen in this World War II adventure story based on an actual mission

Just to confirm, the submarine was sunk off the Western Approaches. I was the Nav Officer on board the Admiralty tug RMAS Rollicker, and we towed the submarine from Loch Ewe out into the NW Approaches for a 'sinkex'; however, we hit Storm Force 11, which forced us to cancel the sinkex. A few months later she was towed out into the SW Approaches for the sinkex.
