HMS Westcott (D47) was a Royal Navy Admiralty W-class destroyer that served in the Second World War. In the Second World War Westcott served in an anti-submarine role and escorted numerous Atlantic and Malta convoys.
On 9 December 1916, the British Admiralty placed an order for 21 large destroyers based on the V class, which became the Admiralty W class. Of these destroyers, two, Westcott and were ordered from the Scottish shipbuilders William Denny and Brothers.
Westcott was long overall and between perpendiculars, with a beam of and a draught of between and depending on load. Displacement was standard, and up to deep load. Three oil-fed Yarrow boilers raising steam at fed Brown-Curtis geared steam turbines which developed , driving two screws for a maximum designed speed of . The ship carried of oil giving a range of at .
Westcotts main gun armament consisted of four 4-inch Mk V QF guns in four single mounts on the ship's centerline. These were disposed as two forward and two aft in superimposed firing positions. A single QF 3-inch (76 mm) 20 cwt anti-aircraft gun was mounted aft of the second funnel. Aft of the 3-inch gun, she carried six 21-inch torpedo tubes mounted in two triple mounts on the center-line.
Westcott was laid down at Denny's Dumbarton, Scotland shipyard on 30 March 1917, and was launched on 14 February 1918. She was commissioned on 2 April and completed on 12 April. She was named after Captain George Blagdon Westcott, who was killed at the Battle of the Nile.
On commissioning, Westcott joined the 13th Destroyer Flotilla of the Grand Fleet, based at Rosyth in support of the Battlecruiser Force, remaining there for the remainder of the war. In 1919, the Grand Fleet was disbanded, and the Atlantic Fleet took its place, supported by four destroyer flotillas. Westcott joined the Second Destroyer Flotilla, based at Rosyth. In August 1919, the Second Destroyer Flotilla, including Westcott, was deployed to the Baltic as part of the British intervention in the Russian Civil War, relieving the First Destroyer Flotilla. The Second Flotilla remained in the Baltic until December 1919. In February 1920, Westcott was deployed to the Mediterranean, shelling Turkish forces during the Greco-Turkish War, before returning to Britain in August.
In 1921, as large flotillas of sixteen destroyers had proved difficult to control, it was decided to reorganise the destroyers of the Atlantic Fleet, changing to six flotillas each comprising a Flotilla leader and eight destroyers. Westcott was assigned to the Sixth Flotilla. Westcott was refitted at Sheerness from July 1930 to March 1931, having her boilers retubed. At some stage prior to 1931, the 3-inch gun was replaced by a 2-pounder "pom-pom". On 4 January 1933, she stood by the French Ocean liner after the liner caught fire in the English Channel and was abandoned by her crew. Wescott remained with the Atlantic Fleet (and after 1932 the Home Fleet) until April 1935 when she was reduced to reserve at Devonport.
She returned to active service with the 21st Destroyer Flotilla in September 1935 as a result of the Abyssinia Crisis. On 18 March 1936, Westcott suffered an accidental explosion when on exercise in the Mediterranean. One man was killed, with a further 10 injured. In April 1936 she returned to reserve at Devonport. Westcott was then refitted in preparation for duty with the Fourth Submarine Flotilla based on the China Station. One 4-inch gun and the aft set of torpedo tubes was replaced by a crane for retrieval of practice torpedoes fired by the submarines of her flotilla, and sonar was fitted.
On the outbreak of the Second World War, Westcott was still allocated to the Fourth Submarine Flotilla, and was having her armament restored to suit her for full operational service. In January 1940, Westcott was assigned to the Mediterranean Fleet, reaching Malta on 14 February. In April 1940, she was recalled to British waters, reaching Devonport on 19 April. She was then assigned to operations off Norway as a response to the German invasion, taking part in the evacuation of British troops from ÃÂ ndalsnes on the night of 30 April/1 May, and continuing to operate off Norway for the rest of the month. In early June 1940 Westcott took part in the escort of a convoy (including the liners , , , and ) carrying Australian troops to the United Kingdom, on the leg from Gibraltar to Britain. Westcott then took part in Operation Aerial, the evacuation from ports in Western France of Allied troops who had remained in France following the evacuations from Dunkirk and Le Havre. Westcott was sent to Brest, but collided with the coaster Nyroca on 17 June, with both ships returning to the United Kingdom empty.
On 4 July, Westcott joined the 4th Destroyer Flotilla, based at Devonport for escort duties in the North Atlantic. On 5 July, the destroyer was detached from Convoy OB178 to investigate a possible submarine sighting. While hunting the submarine, , Whirlwind was torpedoed, blowing off the destroyer's bow. Westcott went to the aid of Whirlwind, rescuing the survivors of her crew and scuttling the stricken destroyer with torpedoes when it was realized that it would not stay afloat until rescue tugs would arrive. 57 of Whirlwinds crew were killed. On 2 September 1940, Westcott, with the destroyer , the sloops and and the corvette , joined inbound Atlantic convoy SC.2 as escort. Over the next few days, the convoy was subject to a series of attacks by German U-boats which sank five of the 53 merchant ships of the convoy (four of them by , commanded by Günther Prien). This was the first successful Wolfpack attack of the Second World War.
In November 1940, Westcott transferred to the 5th Escort Group, based at Liverpool. On 16 January 1941, along with the Royal Navy tugs HMS Superman and HMS Tenacity, she rescued 143 survivors from , which had torpedoed and sunk in the Western Approaches. On 28 January, Westcott collided with the corvette , and after repair at Liverpool, which was slowed by German air raids, joined the 7th Escort Group, also based at Liverpool. Westcott was fitted with a prototype Hedgehog anti-submarine mortar, which replaced the forward 4-inch gun, in August 1941. As a test platform, Westcott became the first vessel to be equipped with Hedgehog. She remained part of the 7th Escort Group at the start of October 1941, and transferred to the Gibraltar Escort Group in December 1941, having her boiler tubes repaired from 24 December 1941 to 14 January 1942.
On 16 January 1942, the troopship was torpedoed and damaged by the German U-boat , but managed to reach Horta in the Azores. After limited repairs, Llangibby Castle left Horta for Gibraltar on the night of 1/2 February, with three destroyers of the Gibraltar Escort group, Westcott, and allocated as escorts. Westcott and Croome patrolled off the south exit from Horta harbour while Exmoor escorted Llangibby Castle through the North exit. The
