HM Submarine Trump - P333 - T Class
HMS Trump (pennant number P333) was a British submarine of the third group of the T class. She was built by Vickers Armstrong, Barrow, and launched on 25 March 1944 Trump survived world war two and continued in service with the Royal Navy. Trump was one of several all-welded T-class submarines rebuilt for greater underwater performance, the "Slippery T" or "Super T" conversion involved the removal of the deck gun and the replacement of the conning tower with a streamlined "fin" (as pictured here). She was sold off and broken up for scrap in August 1971. Date: circa 1947

WW1 - A scene of Dover at night as it's searchlights discover two German submarines at the entrance of the harbour. The English Batteries opened fire on the water from the eastern forts. The picture was reported as an imaginative enemy-picture reproduced from a well-known German paper. It is unknown whether the attack were repulsed or if the two German submarines were sunk.
