HMS Milbrook (1915)

HMS Milbrook was an Admiralty M-class destroyer which served in the Royal Navy during the First World War. The M class was an improvement on those of the preceding L-class destroyer, capable of higher speed. The destroyer was launched in 1915 and joined the Eleventh Destroyer Flotilla of the Grand Fleet. In 1916, Milbrook responded with the Grand Fleet to the bombardment of Yarmouth and Lowestoft and fought in the Battle of Jutland. During the following year, the warship was transferred to Buncrana to operate under the Commander-in-Chief, Coast of Ireland and, for the remainder of the war, the destroyer escorted convoys that were arriving and departing ports on the Clyde and Mersey to cross the Atlantic. In 1918, the ship was jointly responsible for the destruction of the German submarine SMU UB-124. After the Armistice, Milbrook was placed in reserve before being sold to be broken up in 1921.

Design and development
Milbrook was one of the sixteen Admiralty M-class destroyers ordered by the British Admiralty in September 1914 as part of the First War Programme. The M class was an improved version of the earlier L-class destroyer (1913), required to reach a higher speed in order to counter rumoured new German fast destroyers. The remit was to have a maximum speed of 36 kn and, although ultimately the destroyers fell short of that ambition in service, the extra performance that was achieved was valued by the navy. It transpired that the rumoured German warships did not exist

The destroyer had a length of 265 ft between perpendiculars and 273 ft overall, with a beam of 26 ft and draught of 8 ft. Normal displacement was 976 LT. Power was provided by three Yarrow boilers feeding Brown-Curtiss steam turbines rated at 23000 shp, driving three shafts and exhausting through three funnels. Design speed was 34 kn, but Milbrook only managed 32.75 kn on 22750 shp during trials. A total of 228 LT of oil was carried, which gave a design range of 2530 nmi at 15 kn.

Milbrook had a main armament consisting of three single QF 4 in Mk IV guns on the centreline, with one on the forecastle, one aft on a raised platform and one between the middle and aft funnels. Torpedo armament consisted of two twin torpedo tubes for 21 in torpedoes located aft of the funnels. Two single 1-pounder 37 mm "pom-pom" anti-aircraft guns were carried. The anti-aircraft guns were later replaced by single 2-pdr 40 mm "pom-pom" guns. The ship had a complement of 80 officers and ratings.

Construction and career
Milbrook was laid down by John I. Thornycroft & Company at their yard in Woolston, Southampton in November 1914, was launched on 12 July the following year and was completed three months later in October 1915. Unlike others built by the shipyard, the destroyer was built to an Admiralty specification. The vessel was the second to enter Royal Navy service to be given the name.

Milbrook was deployed as part of the Grand Fleet, joining the Eleventh Destroyer Flotilla. On 26 and 27 February 1916, the flotilla took part in a large naval exercise east of Shetland, involving four flotillas of destroyers, as well as all the operational battlecruisers, battleships and cruisers of the Grand Fleet. The exercise was deemed a success. On 24 April, the destroyer was based at Cromarty on the east coast of Scotland. The flotilla formed part of the support for the Grand Fleet in their response to the German bombardment of Yarmouth and Lowestoft which took place on that day. However, the slower speed of the destroyers in the choppy seas meant that they were left behind and they did not encounter the German fleet.

During the following month, the destroyer sailed back to Cromarty along with eight other destroyers from the flotilla and the flotilla leader HMS Kempenfelt (1915) to meet with the Second Battle Squadron. The ships sortied to rendezvous with the remainder of the Eleventh Destroyer Flotilla under the light cruiser HMS Castor (1915) on 31 May. They then sailed along with the rest of the Grand Fleet to confront the German High Seas Fleet in the Battle of Jutland. As the two fleets converged, the flotilla formed close to the dreadnought battleship HMS King George V (1911), leading at the head of the Second Battle Squadron. In the skirmish, Milbrook took no hits. As the German fleet withdrew during the night, the destroyers, led by Castor, attacked the German light cruisers of the Fourth Scouting Group, although Milbrook again was not able to achieve any hits. After the battle ended, the vessel returned to Scapa Flow with the remainder of the flotilla, arriving on 2 June.

The destroyer remained part of the Eleventh Destroyer Flotilla on 19 August, based at Scapa Flow. During the following year, Milbrook was transferred to the Northern Division of the Coast of Ireland Station based at Buncrana. The destroyer was part of the escort service provided to convoys travelling across the Atlantic. The destroyers at Buncrana assisted convoys travelling across the Atlantic Ocean to and from the American industrial complex at Hampton Roads and via Sydney, Nova Scotia, arriving and departing ports on the Clyde and Mersey. The division also provided three escorts every eight days to protect fast convoys travelling to and from Halifax, Nova Scotia. The convoy escort role continued into 1918. On 20 July, the destroyer, along with sister ships HMS Marne (1915) and HMS Pigeon (1916), successfully drove the German submarine SMU UB-124 to the surface with depth charges. The ships then sank the submarine with gunfire.

After the Armistice that ended the war, the Royal Navy returned to a peacetime level of strength and both the number of ships and the amount of personnel needed to be reduced to save money. The destroyer was transferred to reserve at Portsmouth. However, the harsh conditions of wartime operations, particularly the combination of high speed and the poor weather that is typical of the North Sea, exacerbated by the fact that the hull was not galvanised, meant that the ship was soon worn out. Milbrook was declared superfluous to operational requirements, retired, and, on 22 September 1921, was sold to Cohen, and broken up in Germany.
