HMS E1

HMS E1 (laid down as HMS D9) was a British E class submarine built by Chatham Dockyard and cost £101,700. E1 was laid down on 14 February 1911. She was launched on 9 November 1912 and was commissioned on 6 May 1913. During World War I she was part of the British submarine flotilla in the Baltic.

She worked with HMS E5 and reconnoitered the Skagerrak as a prelude to sending submarines into the Baltic. Then on 15 October 1914, she and HMS E9 sailed from Gorleston in a successful attempt to penetrate the German defences and enter the Baltic. On 18 October 1914, E1 unsuccessfully attacked the armoured cruiser Fürst Bismarck in Kiel Bay. On 19 August 1915, she torpedoed and damaged the German battlecruiser Moltke (23,000 tons) during the Battle of the Gulf of Riga.

E1 met her fate on 3 April 1918 outside Helsinki, 1.5 nautical miles (2.8 km) off Harmaja Light in the Gulf of Finland. She was scuttled by her crew, along with E8, E9, E19, C26, C27, and C35 to avoid seizure by advancing German forces which had landed nearby.
