P o s t   W a r   N o t e s

(revised partly from the addendum)


HMS MUTINE remained in the Mediterranean with the 12th Flotilla and continued deployment for mine clearance operations off Genoa and based at Naples until 1946 when she returned to Malta to prepare for return to UK with the rest of the Flotilla. The Flotilla was then deployed was nominated for mine clearance operations off the French, Belgian and Dutch coasts based at Harwich with HM Minesweepers FLY (SO). CADMUS, ACUTE, CIRCE and  ALBACORE. After repair at Portsmouth in August 1946 she resumed Flotilla duties until November when Paid-off and reduced to Reserve status at Sheerness before being laid-up at Harwich. In April 1956 the ship recommissioned to replace HM Minesweeper LYSANDER for minesweeping training based at Portsmouth. When this requirement ceased the ship was used as a ship target for aircraft training and placed back in Reserve at Chatham. Although refitted for use as an anti-submarine escort in 1958-9 whilst in Reserve, she never recommissioned and in 1966 was put on the Disposal List. Sold to BISCO in March 1967 the ship was towed to Barrow where it arrived in tow for demolition by TW Ward at Dalmuir on 7th April that year.

Referring to  the post war service record of HMS MUTINE in which you state she was decommissioned on her return to the UK from Malta, being paid-off at Sheerness. When I joined her in June 1946 at Harwich following my return from serving in the Far East, she was then part of the 12th Flotilla comprising HMS FLY J306 [Flotilla Leader], HMS CADMUS J230 [˝ Leader],  HMS ACUTE J106,  HMS CIRCE J214,  HMS ALBACORE J101 and HMS MUTINE J227. The flotilla was employed locating and sweeping often poorly charted mine fields off the French, Dutch coast and islands. HMS MUTINE underwent minor repairs at Portsmouth Dockyard for a week if I recall correctly in late August 1946. She was finally paid-off in November 1946 at Sheerness. I should just like to recognise the contribution these ships and crews continued to make after the end of war. In a way they are perhaps representative of the post-war navy in general, often undertaking hazardous operations for a country thankfully at peace.
