| 12-05-1941 | HMS Undaunted sailed for her Mediterranean patrol from Malta on 1st May 1941. Ordered to patrol off Tripoli the submarine failed to return on her due date of 11th May and attempts to contact her failed. It is believed that she fell victim to the Italian torpedo boat Pegaso who had sailed from Tripoli on the 12th. At 2030 that evening Pegaso signalled that she had attacked a submarine with depth charges and that a large patch of oil had been observed, indication of the submarines destruction. Against this theory is the fact that by that date Undaunted should have been back in harbour but it is possible that a decision to remain at sea for a day had been taken or that Undaunted may have suffered mechanical problems preventing her return. There is always the every present possibility that the submarine fell foul to a mine. |

| No. of shafts | 2 |
| Endurance | Surface: 4050 miles at 10 knots (design) |
| Submerged: 23 miles at 8 knots or 170 miles at 2.5 knots (design) | |
| Armament | (i) 4 x 21 inch bow tubes (8 torpedoes carried) |
| (ii) 1 x 3 inch gun | |
| 3 x 0.303 inch machine-guns | |
| Complement | (peacetime) 4 Officers, 23 Others, |
| (at war) 4 Officers, 27 Others | |
| Note | (i) The first seven U Class submarines had two additional external bow tubes installed and carried 10 torpedoes |
| (ii) Undine and Unity, which were not fitted with the 3 inch gun, had 27-man complements. |
On the 12th January 1950, HM Submarine Truculent spent the day at sea off the Thames Estuary carrying out trials, following a long refit. Apart from the full crew, there were 18 civilian dockyard officials on board to make any last minute adjustments, as she was due to sail for Scotland the next day. As she made her way up to the Medway Approaches, the Officer of the Watch conned the submarine on the surface. Traffic in the river was heavy and the steaming lights of many ships on their way into and out of the Port of London were clearly visible on all sides.
The Full Story of the 'Battle' of the Isle of May Island. As they approached navigational confusion broke out, caused by the misinterpretation of ship's steaming lights and mayhem followed.
During the next couple of hours five collisions occurred involving eight ships and resulting in the death of 105 officers and ratings. This fiasco and the resulting naval investigation and court marshal were shielded from the general public and kept in secret files until the full details were released in 1994.
From this official report, the author now tells the full story of that dreadful night and the proceedings that followed. Background information on the evolution of the ill-fated and much hated K Class submarines is also included together with the investigation and court marshal proceedings of the events surrounding that tragic night.
