Submarine HMS Thames (N 71)
7 Jul 1940 (position 0.00, 0.00)
Having completed a long refit at the Devonport Dockyard, HMS Thames (Lt.Cdr. W.D. Dunkerley, RN), departed Plymouth for the Clyde area.
HMS Thames had arrived at Plymouth for a long refit on 8 July 1939. It was expected that her refit would take about 6 months but strain on the Dockyard due to wartime conditions and repair work to vessels with a higher priority kept delaying the work on HMS Thames. It therefore took almost a year for the refit to be completed. (1)

HMS Thames (Lt.Cdr. W.D. Dunkerley, RN) arrived in the Clyde area for a period of trials and training. (1)

Thames returned at 1900 hours and berthed outboard of HMS Talisman (Lt.Cdr. P.S. Francis, RN) on the port side of HMS Cyclops (A/Capt. R.L.M. Edwards, RN (who had taken over command of HMS Cyclops from A/Capt. E.H. Longsdon in the afternoon)). (2)

Edwards, RN) Talisman proceeded to Greenock where she anchored for the night before proceeding to the Scotts shipyard the next morning. Most likely HMS Thames went on to the torpedo firing range at Arrochar.

13 Jul 1940
It is reported by the 7th Submarine Flotilla that torpedo salvo firing trials of HMS Thames (Lt.Cdr. W.D. Dunkerley, RN) had gone 'entirely unsatisfactory'. It was suggested that the sailing of HMS Thames was to be delayed until satisfactory salvo firing trials had been carried out and defects had been made good. (1)
17 Jul 1940
The 7th Submarine Flotilla now reported that torpedo salvo firing trials of HMS Thames (Lt.Cdr. W.D. Dunkerley, RN) had now been satisfactory performed. (4)

HMS Thames (Lt.Cdr. W.D. Dunkerley, RN) departed Dundee for her 1st war patrol. She was ordered to patrol off the south-west coast of Norway. (6)
26 Jul 1940 (position 58.27, 4.12)
HMS Thames (Lt.Cdr. W.D. Dunkerley, RN) torpedoed and sank the German torpedo boat Luchs in the North Sea in approximate position 58°27'N, 04°12'E.
Luchs was part of the escort for the damaged German battlecruiser Gneisenau that was on passage from Trondheim, Norway to Kiel, Germany. Other ships of the escort were light cruiser Nürnberg, destroyers Z 5 / Paul Jacobi, Z/14 Friedrich Ihn, Z/20 Karl Galster, torpedo boats Iltis, Jaguar and Kondor.
The counter-attack by the escort of the Gneisenau is reported to have been ineffective and it is very doubtful that HMS Thames was lost as a result of it. This is why the general concensus is that she was mined on her return trip. Of course we may never know the exact cause of the loss of HMS Thames unless the wreck is found. It is however strange that HMS Thames did not make an enemy report following her attack as the Gneisenau was a very important target.
The sinking of the Luchs is often credited to HMS Swordfish. but this is incorrect.
