Narwhal was one of sixteen Admiralty M-classdestroyers ordered by the British Admiralty in February 1915 as part of the Fourth War Construction Programme.[1] The M-class was an improved version of the earlier L-class destroyers, required to reach a higher speed in order to counter rumoured German fast destroyers. The remit was to have a maximum speed of 36 knots (67 km/h; 41 mph) and, although the eventual design did not achieve this, the greater performance was appreciated by the navy. It transpired that the German ships did not exist.[2]
Between 31 May and 1 June 1916, Narwhal sailed as part of the Flotilla, led by the flotilla leaderHMS Faulknor to confront the German High Seas Fleet in the Battle of Jutland.[9] The ship managed to launch two torpedoes from her port side against the German Fleet, but both missed.[10]
In February 1917, the destroyer was transferred to Cobh, Ireland, to counter increasing activity by German submarines in the Southwest Approaches.[11][12] The submarines had been very active and the Royal Navy had resorted to introducing Q-ships to try and ambush them. On 17 February, Narwhal was called upon to rescue the crew of one of these ships, HMS Farnborough, which was sunk by and sank SM U-83.[13] Nine days later, the ship chased away SM U-50 from attacking the armed merchantmanCameronia.[14] Escort duties continued, including accompanying convoys to Liverpool from 27 March.[15]
During 1918, Narwhal was transferred to Devonport as part of the Fourth Destroyer Flotilla.[16] After the Armistice of 11 November 1918 that ended the war, the destroyer remained in Devonport and, shortly afterwards, joined the local defence flotilla at the base.[17]Narwhal was damaged in a collision in 1919 and returned to Devonport to be broken up the following year. The vessel's name was subsequently used by two submarines that served with the Royal Navy.[18]
