HMS E4
HMS E4 was a British E class submarine built by Vickers, Barrow-in-Furness, costing £101,900. E4 was laid down on 16 May 1911, launched on 5 February 1912 and commissioned on 28 January 1913. On 24 September 1915 E4 was attacked by the German airship SL3. On 15 August 1916, she collided with sister ship E41 during exercises off Harwich. Both ships sank and there were only 14 survivors, all from E41. Both boats were raised, repaired and recommissioned. She was sold on 21 February 1922 to the Upnor Ship Breaking Company.
The early British E-class submarines, from E1 to E8, had a displacement of 652 long tons (662 t) at the surface and 795 long tons (808 t) while submerged. They had a length overall of 180 feet (55 m) and a beam of 22 feet 8.5 inches (6.922 m), and were powered by two 800 horsepower (600 kW) Vickers eight-cylinder two-stroke diesel engines and two 420 horsepower (310 kW) electric motors. The class 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), with a fuel capacity of 50 long tons (51 t) of diesel affording a range of 3,225 miles (5,190 km; 2,802 nmi) when travelling at 10 knots (19 km/h; 12 mph), while submerged they had a range of 85 miles (137 km; 74 nmi) at 5 knots (9.3 km/h; 5.8 mph).
The early 'Group 1' E class boats were armed with four 18 inch (450 mm) torpedo tubes, one in the bow, one either side amidships, and one in the stern; a total of eight torpedoes were carried. Group 1 boats were not fitted with a deck gun during construction, but those involved in the Dardanelles campaign had guns mounted forward of the conning tower while at Malta Dockyard.
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.
The complement was three officers and 28 men.
On commissioning, E4 joined the 8th Submarine Flotilla as part of the Home Fleets, and was inspected by King George V at Portsmouth.
E4 remained part of the 8th Submarine Flotilla, based at Portsmouth on the eve of the outbreak of the First World War in August 1914. The planned duties of the 8th Flotilla in times of war was offensive operations in the North Sea, operating from Harwich, and the Flotilla was duly deployed to Harwich at the start of August. On 19 August, E4, together with the submarines E9 and D5 set out from Harwich for a patrol in the North Sea. On 20 August the three submarines were spotted by German torpedo boats west of Helgoland - the sighting resulted in a planned sortie by German cruisers and torpedo boats against British fishing boats on the Dogger Bank being delayed for a day.
On 28 August 1914, E4 was one of eight submarines that took part in a raid against the German Heligoland Bight patrol by the Harwich Force. Three submarines were deployed as bait, with orders to try and get spotted by the German outer screen in order to draw German torpedo boat patrols into the clutches of British destroyers and light cruisers. Meanwhile, E4, together with E9 and E5 were to patrol close to Helgoland. E4 spotted the German torpedo boat V187 being chased by British destroyers but could not get into a position to attack before V187 was sunk by the British destroyers. Shortly afterwards, the German cruiser Stettin arrived, forcing the British destroyers to disperse, and although E4 attempted to attack Stettin, the submarine could not get into a good attack position before Stettin left. A little later, E4 surfaced and picked up the crew of two boats from the destroyer Defender, which were rescuing survivors from V187 when the arrival of Stettin caused the boats to be left behind. E4, short of space, also picked up three German survivors, leaving the remainder in a boat with provisions and a compass. On 10 September, E4 took part in another raid by the Harwich Force, supported by the Grand Fleet against German forces in the Helgoland Bight. While the British surface forces found nothing, the submarines were more busy, with E4 encountering the German submarines U-23 and U-25. E-4 attempted to torpedo the German submarines, but both her torpedoes missed.
