| Possibly sunk off Penang by Japanese A/S aircraft on or about 11th January 1945. On 3rd January 1945 the Submarine left Trincomalee in Ceylon (now Sri Lanka) for her 23rd War Patrol (4th in the Far East) with orders to lay a minefield off Penang. On 9th Jan 1945, Lt. Cdr. H B Turner, DSC is understood to have reported by signal that he had successfully laid her mines off Penang. On 13th January 1945, HMS Stygian was sent a signal informing her that Porpoise was in trouble 17 miles northwest of Pulo Perak). This information came from an Ultra decrypt (now in the National Archives in London) reporting that on 11th January a Nakajima B6N2 bomber had attacked a Submarine, dropping two 60kg bombs. Further bombing attacks we made later but there was no further contact. Japanese records show that a submarine was spotted and bombed by aircraft in the vicinity of Penang. Although not destroyed in this attack, the submarine was wounded and leaking oil that left a trail for the Japanese anti-submarine forces to follow as they closed in for the kill. HMS Porpoise was later declared overdue and then as lost with all hands. | |
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
