1917	K13	Just after noon HMS K13, on trials in the Gareloch, signaled to nearby HMS E50 her intention to dive. As the submarine submerged the engine room began to flood. The submarine became uncontrollable and came to rest on the bottom with the engine room and after torpedo room flooded. The crew of E50 witnessing K13's rapid dive closed in on the area discovering traces of oil and escaping air breaking the surface. The first rescue vessel arrived around midnight. Divers were sent down to inspect the submarine and just after daybreak on the 30th morse signals were exchanged between the divers and the trapped crew. At 1700 an airline was successfully connected, empty air bottles recharged and ballast tanks blown. With the aid of a hawser slung under her bows K13 was brought to within 8 feet of the surface. By midday of the 31st K13's bow had been raised ten feet above the water. By 2100 the pressure hull had been breached using oxyacetylene cutting equipment the survivors being transferred to safety. K13 was finally raised on 15th March, refitted and returned to service as HMS K22.

1932	HMS M2	Foundered due to a leak in the hangar door on 26th January 1932 At 9 o’clock on the morning of 26th January 1932 HMS M2 left Portland to take part in routine exercises. At 1011 she signalled her intention to dive at 1030. This was the last communication with the submarine. The loss of radio communication did not cause any consternation until M2 failed to return to port as expected at 1615. Search vessels were dispatched but there was no sign of the submarine or her crew. No explanation could be found for her loss until the Admiralty received a report from the captain of the coaster Tynesider which reported seeing a submarine diving stern first off Portland. This had caused the Captain some anxiety but he thought he saw the same submarine a short time later. M2’s exact position remained a mystery for a week until the Destroyer Torrid picked up sonar sounds that indicated a sunken submarine; divers confirmed this to be M2 lying with her stern in the sand at a depth of 90ft Two bodies were recovered from the wreck during the next week. A number of attempts were made to raise the vessel but all failed.
