Wales and the Welsh people experienced the Great War at sea in numerous ways. Bringing together historians, archaeologists, marine scientists, museums and community groups across Wales, the U-Boat Project, 1914-18: Commemorating the War at Sea tells their stories.

The DERBENT was a tanker built by Armstrong Whitworth & Co Ltd. at Newcastle-upon-Tyne in 1907. She was requisitioned by the Admiralty in 1914 to be used for refuelling Royal Naval vessels. The DERBENT was torpedoed by UB 96 on 30 November 1917.

Fred Morgan was from Tonypandy in the Rhondda Valley and worked as a merchant sea officer before the war. In November 1917, the OVID on which he served was on a voyage from Bombay to the Mediterranean with an Admiralty cargo when it was sunk off Crete by the German submarine UC 74. Two people were lost.
