August 6th - On This Date - RN Submarine Service

1940	HMS Sealion	HMS Sealion fires four torpedoes against the German merchant Cläre Hugo Stinnes off Kristiansand, Norway. All torpedoes missed their target.
1942	Thorn	Lost. On the 7th August 1942 HMS Thorn encountered the Italian torpedo boat Pegaso, escorting the steamer Istria from Benghazi, 30 miles south west of Gaudhos Island, off southern Crete. At 1255 an escorting aircraft was seen to machine-gun the seas surface and Pegaso moved in to investigate. Just four minutes after the aircraft's attack the Pegaso picked-up a contact and carried out seven attacks after which contact was lost. HMS Thorn failed to return from the patrol and is believed to have been lost in this attack.
1942	HMS Turbulent	HMS Turbulent torpedoes and sinks the wreck of the Italian destroyer Strale off Cape Bon.
1943	HMS Parthian	Mined & sunk in Mediterranean In July HMS Parthian sailed from Malta for a patrol in the southern Adriatic. On the 26th she was ordered to patrol off Capo Otranto. This order was cancelled on the 28th when a new patrol area was given. The submarine was signalled on 6th August to leave the patrol. This signal was not acknowledged and not further contact was made with the submarine. Parthian was due to arrive at Beirut on 11th August, her failure to do so was probably caused by a mine on or around 6th August.
1943	HMS Shakespeare	While on patrol north-west of Ustica, HMS Shakespeare fires three torpedoes at what is identified as an Italian light cruiser. All torpedoes missed their target.
