Minesweeping Trawler.
Wildfire Queenborough.

Built in 1906 the Delphinus saw service in World War One as a minesweeper where on the 18th and 19th January 1917 she salvaged the SS Anders (LG30538).

Surprisingly during WW1 Royal Navy warships still received Prize Bounty Money for the capture of enemy ships. They also received Salvage Money for saving ships and their cargoes.

At the outbreak of World War Two the Delphinus was again requisitioned by the Admiralty to be used as a minesweeper and based at the Minesweeper Base Wildfire III, Queenborough. 

Nov 39, Requisitioned and converted to a minesweeper.

​During her service in World War One, Albert Septimus McDermott served on her as an Engineer. Born in Hull in 1885,  he sailed out of the Orkneys on the Steam Trawler St Romanus after the war.

Leading Seaman Harold Rayner was stationed at HMS St Tudno, (Wildfire III) on the minesweeper Delphinus from 14 November 1943 to 18 June 1945

Prior to that, he was stationed in Iceland at the British WW2 land base Baldur on HMS Venture. It was so cold that ice had to be hacked off the ship to stop it becoming top heavy.

Louise tells us that Harold never conquered sea sickness and that he once had his kit bag stolen and had to pay for new uniform and lost all his belongings when someone “helped him” carry it on board when he was injured and had to return from his base at Baldur in Iceland to Meanskirk hospital in Glasgow, on a hospital ship! 

After 4 months in hospital Harold was transferred to St Tudno (HMS Wildfire III) where he joined the Delphinus.

The Delphinus was involved in sweeping for D Day and opening up the Scheldt, the biggest minesweeping operation of WW2.

HMT Delphinus. During her conversion, the Delphinus had a deckhouse added forward of the bridge together with an upper bridge and searchlight. She was first employed on auxiliary patrol work and then minesweeping. The acustic  hammer for sweeping acustic mines can be seen on her bow.
