| Whilst carrying torpedoes which were fuelled by Hydrogen Peroxide she suffered an explosion whilst alongside in Portland Harbour on the 16th June 1955. Sidon sank twenty minutes after the explosion with the loss of 13 lives. Expended as an anti-submarine target 14th June 1957. | |
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
