Construction and career
At the onset of the Second World War, Unity was a member of the 6th Submarine Flotilla. From 26–29 August 1939, the flotilla deployed to its war bases at Dundee and Blyth. She served in home waters in the North Sea, making a failed attack on the German submarine U-2.
Unity sailed from Blyth on 29 April 1940 to patrol off Norway. The visibility was down to 300 yards (270 m) as Unity moved out of the harbour into the main channel, where the Norwegian ship Atle Jarl was proceeding on her way from Scotland to the Tyne. A short while later visibility was down to 100 yards (91 m) and neither vessel was aware of the other until the submarine spotted the Atle Jarl at 50 yards (46 m) on a collision course. There was just time to shut the bulkhead doors and order the engines astern before Atle Jarl smashed into the submarine. The order to abandon the submarine was given and Unity sank only five minutes after the collision. Two members of her crew, Lieutenant John Low and able Seaman Henry Miller, gave their lives by remaining behind in the flooded control room so that their shipmates could escape from the sinking vessel.
