HMS Seahorse was a first-batch S-class submarine (often called the Swordfish class) built for the Royal Navy during the 1930s. Ordered in March 1931, she was laid down at Chatham Dockyard in September 1931 and launched on 15 November 1932.

At the start of World War II, Seahorse was conducting a patrol southwest of Stavanger, Norway. While returning to port after her first and uneventful patrol, Seahorse was erroneously attacked with depth charges by a British aircraft. After repairs, she conducted a second war patrol, sighting the surfaced submarine Шаблон:GS on 13 November 1939. Her torpedoes missed their target, however. During her next patrol on 30 October, Seahorse sighted another German submarine, Шаблон:GS, but it submerged before torpedoes could be launched. On 18 November, Seahorse spotted two German ships, very probably the destroyers Шаблон:Ship and Шаблон:Ship, but failed to maneuver into an attack position. On 26 December, Seahorse departed for her sixth and last war patrol, off Heligoland Bight, with orders to patrol off Heligoland then shift to the mouth of the Elbe on 30 December, then return to port on 9 January 1940, but she did not return on her due date. It was originally thought that she had struck a mine, but German records, examined after the war, suggest she was sunk by the German First Minesweeper Flotilla, which reported an attack on an unidentified submarine on 7 January 1940. It is, however, also possible that she was rammed and sunk by the German Sperrbrecher IV/Oakland southeast of Heligoland on 29 December 1939.

Design and description

The S-class submarines were designed as successors to the L class and were intended to operate in the North and Baltic Seas.[1] The submarines had a length of Шаблон:Convert overall, a beam of Шаблон:Convert and a mean draught of Шаблон:Convert. They displaced Шаблон:Convert on the surface and Шаблон:Convert submerged.[2] The S-class submarines had a crew of 38 officers and ratings. They had a diving depth of Шаблон:Convert.[3]

For surface running, the boats were powered by two Шаблон:Convert diesel engines, each driving one propeller shaft. When submerged each propeller was driven by a Шаблон:Convert electric motor. They could reach Шаблон:Convert on the surface and Шаблон:Convert underwater.[4] On the surface, the first-batch boats had a range of Шаблон:Convert at Шаблон:Convert and Шаблон:Convert at Шаблон:Convert submerged.[3]

The boats were armed with six 21-inch (533 mm) torpedo tubes in the bow. They carried six reload torpedoes for a grand total of a dozen torpedoes. They were also armed with a 3-inch (76 mm) deck gun.[2]

Construction and career

Ordered on 13 March 1931, HMS Seahorse was laid down on 14 September 1931 in Chatham Royal Dockyard and launched on 15 November 1932.[2] The boat was commissioned the next year, on 2 October 1934, and received the pennant number 98S.[5]

On 22 September 1938, Seahorse was damaged in an accidental collision with the destroyer HMS Foxhound.[6]

World War II

At the onset of World War II, Seahorse was a member of the 2nd Submarine Flotilla. From 23–26 August 1939, the 2nd Submarine Flotilla transferred to its war base at Dundee.[7] On 24 August, Seahorse, under the command of Lt. D.S. Massy-Dawson left Dundee, assigned to a patrol position southwest of Stavanger, Norway. At the start of World War II, this became her first war patrol. After her uneventful patrol, Seahorse, returning to Dundee, was erroneously attacked with depth charges by a British aircraft at 20:07 (UTC) in position Шаблон:Coord. Seahorse had dived upon spotting the aircraft, but her diving planes jammed, causing her bow to come out of the water. Seahorse dived again and hit the Шаблон:Convert deep bottom heavily, causing damage to her ASDIC dome. The attacking aircraft was heavily damaged by the blast of her own bombs and ditched. The next day, on 6 September, Seahorse ended her patrol in Dundee, then shifted to Rosyth for repairs later that day.[5]

On 12 September, Seahorse returned to Dundee after repairs and left for her second war patrol on 16 September, again assigned to the southwest coast of Norway. The next day, Seahorse sighted the surfaced German U-boat Шаблон:GS which was attacking the Danish merchant ship N.J. Ohlsen. Three torpedoes were launched in position Шаблон:Coord, but all missed their target. On 2 October, Seahorse ended her second war patrol in Dundee, and, after a stop at Rosyth, departed for her third patrol on 17 October. This time, Seahorse was ordered to patrol the southern coast of Norway. On 30 October 1939, Seahorse sighted a submarine, which may have been the German Шаблон:GS, but the submarine dived before torpedoes could be fired. On 31 October, Seahorse returned to Rosyth, ending her third war patrol.[5]

After a stop at Blyth, Seahorse departed for her fourth war patrol on 12 November, to the northwest of the Netherlands. On 18 November, she sighted two ships, very probably the German destroyers Шаблон:Ship and Шаблон:Ship, but Seahorse could not maneuver into an attack position. On 28 November, Seahorse returned to Blyth after her uneventful fourth patrol.[5]

On 13 December, Seahorse departed Blyth to patrol the British east coast, but returned to port two days later after, having been recalled.[5]

Last patrol

On 26 December, Seahorse departed for her sixth and last war patrol, off Heligoland Bight. Her orders were to initially patrol off Heligoland and then move to the mouth of the Elbe on 30 December. She was expected to return to Blyth on 9 January. Initially it was assumed that she was likely to have been mined but after the end of the war after examining German records it was considered possible that she could have been sunk by the German First Minesweeper Flotilla which reported carrying out a prolonged depth charge attack on an unknown submarine on 7 January 1940.[8] It is however also possible that she was rammed and sunk by the German Sperrbrecher IV/Oakland southeast of Heligoland on 29 December 1939.[5] Seahorse was the first British submarine lost to enemy action during World War II.[9]
