Early history

P216 was ordered from Cammell Laird Shipyard, Birkenhead on April 4thth 1940, one of the batch two boats ordered as part of the third group of S class submarines for the Royal Navy. Her keel was laid down on December 31st 1940. She was launched on June 11th 1942.

On completion of her builder’s trials she departed for Holy Loch on September 22nd to begin a period of trials and training, she was escorted by the ASW Trawler HMS BUTSER arriving three the next day. morning of the 24th she conducted full power trials on the Arran measured mile. On arrival back in Holy Loch she commissioned as H.M. Submarine P216 (SEADOG) under the command of Lieutenant A.R. Daniell, DSC, RN.

While at Holy Loch she conducted Torpedo, Gunnery, Bombardment, D/F and RDF exercises and performed simulated day and night attacks, both submerged and surface actions. She also performed trials at the torpedo firing range at Arrochar. Local vessels acted as targets; conducted night attack exercises with HMS GRAPH (ex-German submarine U-570) on October 1st and further night exercises in the Clyde area with the Dutch submarine HNMS DOLFIJN on the 30th

HMS P216 departed Holy Loch for Lerwick on November 5th from which she would sail for her first war patrol, as part of her work up. She took passage with the Submarines with HMS P312 (TRESPASSER) and TROOPER escorted by the minesweeper HMS La CAPRICIEUSE. On the 6th while still on passage urgent new orders arrived; P216 and P312 were to set course immediately for their patrol areas off the Norwegian coast in response to intelligence that a German 'heavy unit' was thought to be on the move from Norway to the Baltic. Despite both boats being allocated new patrol areas on the 11th no vessels were sighted. P216 arrived at Lerwick on the 30th, ending her first war [patrol, P312 had arrived the day before. Both Submarines departed Lerwick for Holy Loch later on the 3oth escorted by the ASW Trawler HMS SCALBY WYKE until 1300 on the December 1st when the ASW Trawler HMS FOXTROT took over the escort. They arrived at Holy Loch on the 2nd.

She was to make 11 more war patrols from the UK before she was reallocated for service in the Far East.

Allocated to the Eastern Fleet

H.M. Submarine SEADOG departed the Clyde for Gibraltar on first leg of her passage to the Far East; she took pottage with in convoy OS.97 / KMS.77. From Gibraltar she sailed to Malta, Port Said, and Aden arriving at Trincomalee, Ceylon on January 17th 1945. Here she joined the 2nd Submarine Flotilla attached to the depot ship HMS WOLFE. She began her 13th war patrol, her 1st in the East Indies on the 17th operating off the Andaman Islands in the Bay of Bengal.

&SEADOG completed three more war patrols operating off and the West coast of Siam, the Andaman Islands and Northern Sumatra and the in the Malacca Strait. She ended her 16th war patrol (4th in the East Indies) at Trincomalee on August 12th. She was in Trincomalee harbour when the Japanese surrender was announced on the 15th.

 

Return to the UK and disposal

Now surplus to requirements SEADOG was to return to the UK to be placed in the reserve; she sailed from Trincomalee for Port Suez on September 6th. After calling at Port Suez, Port Said, Alexandria, Malta and Gibraltar she arrived at Portsmouth on October 18th. Eleven days later she departed Portsmouth for Harwich, on arriving there on October 30th she was transferred to the Reserve Fleet.

Coming home

In March 1946 I joined 812 squadron, aboard HMS Vengeance, spending some time ditching American aircraft north of Australia. Eventually we sailed for Ceylon ( Sri Lanka ) landing at Trincomalee and setting up a radio section at Katakarunda. In the belief that we were exhausted we were sent to a rest camp at Kandy for a few weeks. We moved down to Colombo to pick up Vengeance and returned to Portsmouth via the Suez Canal . I was discharged in November 1946.
