Service history

She worked with E5 and reconnoitered the Skagerrak as a prelude to sending submarines into the Baltic. Then on 15 October 1914, she and 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 SMS Victoria Louise in Kiel Bay. The torpedo ran too deep and missed.[1] On 19 August 1915, she torpedoed and damaged the German battlecruiser Moltke (23,000 tons) during the Battle of the Gulf of Riga.

E1's service ended 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.
