| 1942 | P 38 | HMS P38 left Malta on 16th February 1942 to intercept a convoy off Tripoli. By the 23rd she was in position as the convoy hove into view. Amongst the convoy was the Italian destroyer Circe. At 0800 the Circe reported contact with a submarine and the warships turned to attack. A periscope was sighted but was quickly replaced by bubbles as the submarine dived realising it had been spotted. At 1050 after a flurry of attacks HMS P38 rose stern first out of the water, her propellers turning wildly, before crashing back beneath the waves. A large patch of oil appeared on the surface as well as debris - clear evidence of the submarines destruction. |
