Able Seaman Henry Miller, 39 and from Southsea, was serving onboard the submarine HMS Unity when she was in Blyth harbour, North East England on 29 April 1940.
Shortly after leaving to begin a patrol in the North Sea HMS Unity collided with the Norwegian Freighter Atle Jarl taking the First Lieutenant and Able Seaman Miller with her. They had remained in the flooded control room to allow the rest of the crew to escape
On 16 August 1940 he was awarded a Posthumous Gallantry Medal of the Oorder of the British Empire. Sometime later when the George Cross was instituted for acts of bravery that were not in the face of the enemy, his Miller’s medal was exchanged for the George Cross.
He has no grave other than the sea, and is remembered on the Portsmouth Naval Memorial.
