HMS E9 was a British E class submarine built by Vickers, Barrow. She was laid down on 1 June 1912 and was commissioned on 18 June 1914.
Like all post-E8 British E-class submarines, E9 had a displacement of 662 long tons (673 t) at the surface and 807 long tons (820 t) while submerged. She had a total length of 180 feet (55 m) [1] and a beam of 22 feet 8.5 inches (6.922 m). She was powered by two 800 horsepower (600 kW) Vickers eight-cylinder two-stroke diesel engines and two 420 horsepower (310 kW) electric motors. [2] [3] The submarine had a maximum surface speed of 16 knots (30 km/h; 18 mph) and a submerged speed of 10 knots (19 km/h; 12 mph). British E-class submarines had fuel capacities of 50 long tons (51 t) of diesel and ranges of 3,255 miles (5,238 km; 2,829 nmi) when travelling at 10 knots (19 km/h; 12 mph). [1] E9 was capable of operating submerged for five hours when travelling at 5 knots (9.3 km/h; 5.8 mph).
E9 was not fitted with a deck gun during construction, and it is not known whether one was fitted later, as was the case with many boats up to E19. She was the first of her class to be constructed with five 18 inch (450 mm) torpedo tubes, two in the bow, one either side amidships, and one in the stern; a total of 10 torpedoes were carried. [2]
E-Class submarines had wireless systems with 1 kilowatt (1.3 hp) power ratings; in some submarines, these were later upgraded to 3 kilowatts (4.0 hp) systems by removing a midship torpedo tube. Their maximum design depth was 100 feet (30 m) although in service some reached depths of below 200 feet (61 m). Some submarines contained Fessenden oscillator systems. [1]
Her complement was three officers and 28 men. [1]
When war was declared with Germany on 5 August 1914, E9 was based at Harwich, in the 8th Submarine Flotilla of the Home Fleets. [4]
At dawn on 13 September 1914, the submarine, commanded by Lieutenant-Commander Horton, torpedoed the German light cruiser SMS 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. [5] Three weeks later, Horton sank the German destroyer S116 off the mouth of the River Ems. For sinking the cruiser and the destroyer, Horton was awarded the Distinguished Service Order (DSO).
E9 was scuttled outside Helsinki (Helsingfors) 1.5 nautical miles (2.8 km; 1.7 mi) off Grohara Light in the Gulf of Finland on 3 April 1918 to avoid seizure by advancing German forces.
HMS E9 was salvaged for breaking in Finland in August 1953.
While in command of the E9, Horton initiated the tradition of submarines flying the Jolly Roger upon returning from successful combat patrols. Remembering comments by First Sea Lord Admiral Sir Arthur Wilson, who complained that submarines were "underhanded, unfair, and damned un-English" and that personnel should be hanged as pirates, [6] [7] Horton flew the flag when the E9 returned to port following the sinking of the Hela. They flew additional flags after each successful patrol, but when there was no room for more flags, they began adding symbols, each indicating a certain achievement, to a single large flag. [8] This practice was imitated by other British submarines during World War I, and it was renewed again during World War II. The Admiralty initially disapproved of the practice, but was unable to stop it. [7] The Jolly Roger has since been adopted as the logo of the Royal Navy Submarine Service. [9]
HMS E3 was the third E-class submarine to be constructed, built at Barrow by Vickers in 1911–1912. Built with compartmentalisation and endurance not previously achievable, these were the best submarines in the Royal Navy at the start of the First World War. She was sunk in the first ever successful attack on one submarine by another, when she was torpedoed on 18 October 1914 by U-27 north of Schiermonnikoog, the Netherlands.
