Seahorse (S98)
| Built By: | Chatham Dockyard (Medway) |
| Build Group: | S Group 1 |
| Fate: | Mined while moving between Zones E and B in the Heligoland Bight. |
The Submarine was never heard from after sailing from Blyth on 26th December 1939 for patrol off western Jutland. Her operational area was to be initially off Heligoland then move to the mouth of the Elbe on 30 December and return to Blyth on 9th January 1940.
She was most likely sunk after being attacked and depth charged by ships from the German 1st Minesweeping Flotilla on about fifteen nautical miles north-west of Heligoland in position 54º19'N, 07º30'E.

Events
| 14-09-1931 : | Laid Down |
| 15-11-1932 : | Launched |
| 02-10-1933 : | Completed |
| 24-08-1939 : | HMS Seahorse departed Dundee to take up a patrol position to the south-west of Stavanger, Norway. When the war with Germany commenced this became her 1st war patrol. |
| 05-09-1939 : | While on the return passage to Dundee HMS Seahorse was bombed in error by a British Anson of 233 Squadron which dropped two 100lb A/S bombs. She sustained some damage which required her to dock. Seahorse had dived when the aircraft was sighted but her after hydroplanes jammed and depth control was lost. In the meantime two depth charges were dropped by the aircraft but these caused no damage. Seahorse then broached and her bow came out of the water. A third depth charge was then dropped but this also caused no damage. Before Seahorse was able to submerge again a fourth depth charge was dropped very close which shook the submarine severely but it caused no damage. Seahorse then went down again and hit the bottom heavily at 220 feet causing damage to her A/S dome. The aircraft had dived so low that the explosions of the bombs damaged it seriously and it had to ditch but the two airmen were rescued. |
| 06-09-1939 : | HMS Seahorse ended her 1st war patrol at Dundee but moved to Rosyth later the same day. |

| 30-10-1939 : | HMS Seahorse sighted a submarine. An attack was started but before torpedoes could be fired the submarine dived. This was most likely U-21 which was patrolling in the same area but the U-boat did not observe the British submarine. |
| 31-10-1939 : | HMS Seahorse ended her 3rd war patrol at Rosyth. |
| 09-11-1939 : | HMS Seahorse departed Rosyth for Blyth. |

| 07-01-1940 : | HMS Seahorse sunk On 26th December 1939 HMS Seahorse sailed from Rosyth for patrol off the east coast of Denmark. Four days later she shifted position to the entrance of the Elbe. She did not return on her due date of 9th January 1940. It was first thought that she had been mined but German records, examined after the war, suggested she was the victim of the German First Minesweeper Flotilla which reported a sustained depth charge attack on an unidentified submarine on 7th January 1940. Thanks to the research of Mr Bob Coppock of the RN Historical Branch, it is now accepted that Seahorse was mined while moving between Zones E and B in the Heligoland Bight. The wreck has been discovered off the Danish coast. |

| Thank you very much for putting together this information on HMS Seahorse. My uncle died on the submarine and is the last man mentioned in the submariner's list, Harry Spencer Windley, known by his family as Brian. My grandmother was devastated by his passing, he was her firstborn son, and I don’t think she ever recovered, as there was no body to bury. Thank you again. Carolyn McFarland Fri, 5 Feb 2021 |
| My grandfather was on this submarine when it was lost. My dad rarely spoke of it, he was only 2yrs old when his dad was at war. I just like that I can look this up and see grand dad has been remembered somewhere. I would have loved to have met my grandfather John Henry White. Hannah White Sun, 19 Feb 2023 |
