HMS Sepoy (1918)

For other ships with the same name, see HMS Sepoy.

HMS Sepoy was an S-class destroyer, which served with the Royal Navy during the First World War and the Russian Civil War. Sepoy was launched in 1918 and initially joined the Grand Fleet. After the Armistice that ended the First World War, the ship was briefly transferred to the Reserve Fleet before sailing to Tallinn in 1919 as part of the Royal Navy response to the fighting there. Sepoy rejoined the Reserve Fleet at the end of the year. In 1922, the destroyer served in the Mediterranean Sea. The ship was later allocated to the naval base in Hong Kong, arriving in 1929. During exercises the following year, a depth charge explosion killed six sailors. The destroyer was also damaged. Following the signing of the London Naval Treaty a few days later, Sepoy returned to the United Kingdom and, in 1932, was sold to be broken up at Newport, Wales.

Design and development

edit
Main article: S-class destroyer

Sepoy was one of twenty-four Admiralty S class destroyers ordered by the British Admiralty on 7 April 1917 as part of the Eleventh War Construction Programme. The design was a development of the R class introduced as a cheaper and faster alternative to the V and W class.[1] Differences with the R class were minor, such as having the searchlight moved aft.[2]

Sepoy had a overall length of 276 ft (84 m) and a length of 265 ft (81 m) between perpendiculars. Beam was 26 ft 8 in (8.13 m) and draught 9 ft 10 in (3.00 m). Displacement was 1,075 long tons (1,092 t) normal and 1,221 long tons (1,241 t) deep load. Three Yarrow boilers fed steam to two sets of Brown-Curtis geared steam turbines rated at 27,000 shaft horsepower (20,000 kW) and driving two shafts, giving a design speed of 36 knots (67 km/h; 41 mph) at normal loading and 32.5 knots (60.2 km/h; 37.4 mph) at deep load. Two funnels were fitted. A full load of 301 long tons (306 t) of fuel oil was carried, which gave a design range of 2,750 nautical miles (5,090 km; 3,160 mi) at 15 knots (28 km/h; 17 mph).[3]

Armament consisted of three QF 4-inch (102 mm) Mk IV guns on the ship's centreline.[4] One was mounted raised on the forecastle, one on a platform between the funnels and one aft.[5] The ship also mounted a single 40-millimetre (1.6 in) 2-pounder "pom-pom" anti-aircraft gun for air defence. Four 21-inch (533 mm) torpedo tubes were fitted in two twin rotating mounts aft.[4] The ship was designed to mount two additional 18-inch (457 mm) torpedo tubes either side of the superstructure but this required the forecastle plating to be cut away, making the vessel very wet, so they were removed.[2] The weight saved enabled the heavier Mark V 21-inch torpedo to be carried.[1] The ship had a complement of 90 officers and ratings.[6]

Construction and career

edit

Laid down on 6 August 1917 by William Denny and Brothers in Dumbarton with the yard number 1099, Sepoy was launched on 22 May the following year.[7] The vessel was the second with the name, given in honour of the Indian infantry, to serve in the Royal Navy.[8] Sepoy was completed on 6 August and joined the Twelfth Destroyer Flotilla of the Grand Fleet.[9]

After the Armistice that ended the First World War, Sepoy was transferred to the Reserve Fleet at Rosyth.[10] However, the escalating civil war in Russia meant that the destroyer was soon back in service. The United Kingdom felt that the Russians were planning to liberate the Baltic States by integrating them into the new Soviet Union.[11] The destroyer formed part of a flotilla under the command of Rear Admiral Sir Walter Cowan, who had returned to Copenhagen with fresh crews after 19 February 1919.[12] Cowan took Sepoy, along with sister ship Seafire and light cruiser Caledon, to Tallinn.[13] The ship remained there until 25 April, when reinforcements arrived.[14] On 3 December, Sepoy was recommissioned in the Reserve Fleet at Chatham,[15] joining the Sixth Destroyer Flotilla of the Mediterranean Fleet.[16] In May 1920, Sepoy was on station at İzmit on the Sea of Marmara, as the Turkish War of Independence continued.[17]

On 2 December 1922, Sepoy was based in Gibraltar but 10 days later departed Malta for Constantinople with sister ship Tourmaline.[18][19] The vessel returned on 23 February.[20]

On 7 January 1927, Sepoy was recommissioned at Nore to join the Eighth Destroyer Flotilla at the Royal Naval base Tamar at Hong Kong.[21] The vessel arrived on 1 October 1929.[22] On 8 April the following year, the destroyer departed for exercises but, on the following day, one of the depth charges carried aft exploded. Three sailors died instantly and another two were lost overboard. The destroyer was damaged but reached the shore safely. Another sailer later died in hospital.[23][24]

Thirteen days later, the London Naval Treaty was signed, which limited total destroyer tonnage in the Royal Navy. The Admiralty was looking to introduce more modern destroyers and so needed to scrap some of the older vessels.[25] Sepoy was one of those chosen for retirement. The ship returned to the United Kingdom and, on 2 July 1932, was sold to Cashmore to be broken up at Newport, Wales.[26]
