British M-Class destroyer, WW1
HMS "Moorsom" was an which served in the Royal Navy during the First World War. The M class was an improvement on the preceding , capable of higher speed. "Moorsom", the first ship to enter navy service to be named after Admiral Sir Robert Moorsom, was launched in December 1914, initially serving as part of the Grand Fleet before being transferred to the Harwich Force the following year. Briefly rejoining the Grand Fleet, the destroyer saw service in the Battle of Jutland in 1916 supporting the British battlecruisers and received hits from a battleship of the German High Seas Fleet. "Moorsom" also undertook other duties, including escorting the troop ship in June 1915 and the minelayer in August 1915 and November 1916. Placed within the Dover Patrol, the destroyer formed part of the cover for monitors including and on attacks on Ostend and Zeebrugge in May and June 1917, and April and May 1918. After the Armistice, the destroyer was placed in reserve and subsequently sold to be broken up in November 1921.
Design and development.
"Moorsom" was one of the initial six s ordered by the British Admiralty in May 1913 as part of the 1913–14 Naval Programme, one of the last destroyers to be ordered before the outbreak of the First World War. The M-class was an improved version of the earlier destroyers, designed to reach a higher speed in order to counter rumoured German fast destroyers, although it transpired these vessels did not exist. Although envisioned to have a maximum speed of , they were eventually designed for a speed slower.
The destroyer was long overall, with a beam of and a draught of . Displacement was normal and full load. Power was provided by three Yarrow boilers feeding Brown-Curtis steam turbines rated at that drove three shafts to give a design speed of . Three funnels were fitted and of oil was carried, giving a design range of at .
Armament consisted of three single QF Mk IV guns on the ship's centreline, with one on the forecastle, one aft on a raised platform and one between the middle and aft funnels. A single 2-pounder "pom-pom" anti-aircraft gun was carried, while torpedo armament consisted of two twin mounts for torpedoes. The ship had a complement of 76 officers and ratings.
Construction and career.
"Moorsom" was laid down by John Brown &amp; Company of Clydebank on 27 February 1914 with the yard number 427, was launched on 20 December, started trials on 1 February in the Firth of Clyde the following year and was completed on 17 March. The vessel was the first to be named after the naval officer Admiral Sir Robert Moorsom. "Moorsom" was deployed as part of the Grand Fleet, joining the newly formed Tenth Destroyer Flotilla.
The destroyer took part in a wide range of activities during the war, usually alongside other members of the flotilla. For example, the flotilla was involved in escorting ships in 1915. "Moorsom" was chosen to accompany on 9 and 10 June as the troop ship sailed to join the Gallipoli campaign. On 16 August, the ship formed part of a flotilla of eight destroyers that escorted the minelayer on a sortie from Sheerness. One of their number, , was torpedoed by the torpedo boats of the German Second Flotilla, but the crew of "Moorsom" thought the explosion meant that they had entered a minefield and, taking refuge behind the minelayer, escaped without harm. By October, the destroyer, along with the rest of the flotilla, had been transferred to the Harwich Force.
At the Battle of Jutland on 31 May 1916, "Moorsom" was attached to the Thirteenth Destroyer Flotilla under the light cruiser . The destroyer was transferred from the Harwich Force, along with , to supplement the Grand Fleet, which had insufficient destroyers to shield both the 1st and 2nd Battlecruiser Squadrons. The flotilla attacked the battlecruisers of the German High Seas Fleet after the destruction of the and . The vessel became separated from the flotilla and instead joined in a melee with German torpedo boats led by . Disengaging, the destroyer sighted the departing vessels of the High Seas Fleet and launched four torpedoes, none of which hit. "Moorsom" did not return to the battle and instead was forced to return to port with damaged oil tanks. It is likely the tanks were hit by shells from the battleship . On 18 August, the destroyer was briefly, with and , again seconded to the Grand Fleet, serving with the 3rd Battle Squadron. By the following day, the ship had returned to the Tenth Flotilla, now based in Dover. On 28 November, "Moorsom" once again escorted "Princess Margaret" on a mission, this time to lay 500 mines west of Borkum.
"Moorsom" was one of eight destroyers of the Tenth Flotilla sent with the destroyer leader to Dunkirk on 19 January 1917 to provide reinforcement to the Dover Patrol in the event of German torpedo attacks on the Dover Barrage and shipping in the English Channel. On 22 January, an intercepted German radio signal warned the British Admiralty that the German Sixth Torpedo Boat Flotilla was to be sent from the High Seas Fleet to reinforce their forces at Flanders. By 27 January, the destroyer was part of a flotilla, which also included , , , "Morris", "Nimrod" and , that was to patrol east of the Schouwen Bank. The force did not see the German ships, but "Moorsom" was nearly accidentally rammed by , which was part of another destroyer division operating in the area, due to the lack of visibility. The warship was then given a refit, returning to Dover on 28 February. "Moorsom" rejoined the Dover Patrol, which now included thirteen monitors, forming part of the Sixth Destroyer Flotilla. On 11 May, the destroyer was part of the escort for the monitors , , and in their bombardment of Ostend. The operation was deemed a success as the Admiralty gained intelligence that the bombardment led to the German command doubting that Ostend was a safe haven for their warships. "Moorsom" formed part of the support for a similar bombardment on 5 June by "Erebus" and "Terror".
The destroyer accompanied a subsequent attack on Zeebrugge by monitors on 23 April 1918, which also included the sinking of blockships to impede the flow of German submarines leaving the port. The ship provided a similar service to the monitors that attacked Ostend on 9 May, which again included "Erebus", "Sir John Moore" and "Terror". Although this operation did not meet the expectations of the Admiralty and the port remained open, the bombardment was achieved without interference by enemy warships or the loss of any British vessel.
After the Armistice of 11 November 1918 that ended the war, the Royal Navy returned to a peacetime level of strength and both the number of ships and personnel needed to be reduced to save money. "Moorsom" was declared superfluous to operational requirements. On 15 October 1919, the destroyer was given a reduced complement and placed in reserve at Devonport. However, this did not last long and, on 8 November 1921, "Moorsom" was sold to Slough TC to be broken up in Germany.
