At dawn on 13th  September 1914, the submarine, commanded by Lieutenant-Commander Horton, torpedoed the German light cruiser Hela six miles southwest of Heligoland. Hela was hit amidships with the two torpedoes, fired from a range of 600 yards. All but two of her crew were rescued by the German submarine U-18 and another German ship. Although pursued most of the day by German naval forces, E9 managed to reach Harwich safely.
