HMS Milbrook (1915)

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.^[13] Unlike others built by the shipyard, the destroyer was built to an Admiralty specification.^[7] The vessel was the second to enter Royal Navy service to be given the name.^[14][15]

Milbrook was deployed as part of the Grand Fleet, joining the Eleventh Destroyer Flotilla.^[16] 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.^[17] On 24 April, the destroyer was based at Cromarty on the east coast of Scotland.^[18] 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.^[19]

During the following month, the destroyer sailed back to Cromarty along with eight other destroyers from the flotilla and the flotilla leader Kempenfelt to meet with the Second Battle Squadron. The ships sortied to rendezvous with the remainder of the Eleventh Destroyer Flotilla under the light cruiser Castor on 31 May.^[20] 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 was briefly called away hunt for what would transpire as non-existent submarines.^[21] Before they met, the flotilla was formed close to the dreadnought battleship King George V, which was leading at the head of the Second Battle Squadron.^[22][23] At 21:00, the destroyers encountered heavy German units and very nearly attacked, but broke off due to fears they were British battlecruisers.^[24] As the German fleet withdrew during the night, the destroyers, led by Castor, are believed to have come under fire from SMS König at 23:45.^[25] They attacked the German light cruisers of the Fourth Scouting Group, although Milbrook again was not able to achieve any hits.^[26] The engagement led them away from the battle, opening the way for the German fleet to escape.^[27] In the action, Milbrook took no hits. After the battle ended, the vessel returned to Scapa Flow with the remainder of the flotilla, arriving on 2 June.^[28]

The destroyer remained part of the Eleventh Destroyer Flotilla on 19 August, based at Scapa Flow.^[29] During the following year, Milbrook was transferred to the Northern Division of the Coast of Ireland Station based at Buncrana.^[30] 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.^[31] The division also provided three escorts every eight days to protect fast convoys travelling to and from Halifax, Nova Scotia.^[32] The convoy escort role continued into 1918.^[33][34] On 20 July, the destroyer, along with sister ships Marne and Pigeon, successfully drove the German submarine UB-124 to the surface with depth charges. The ships then sank the submarine with gunfire.^[35]

After the Armistice that ended the war on 11 November 1918, 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.^[36] The destroyer was transferred to reserve at Portsmouth.^[37] 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.^[38] Milbrook was declared superfluous to operational requirements, retired, and, on 22 September 1921, was sold to Cohen, and broken up in Germany.^[15]
