| 1943 | Simoom (P225) | HMS Simoon believed lost by mines near the Dardanelles. No survivors HMS Simoom sailed for a patrol in the Aegean on 2nd November 1943. On the 5th she received a signal to divert to the entrance of the Dardanelles. Ten days later she was sent orders to return to port. The submarine never arrived. On 15th November German radio broadcasts stated that a submarine had been destroyed in the Aegean and that several of the crew had been rescued. It is unlikely that this was Simoom, as it would have put her miles out of position. None of the claimed survivors stated that they were from Simoom. It is more likely that the submarine struck a mine or was lost through an accident. |
