HMS Wild Swan was an Admiralty modified W-class destroyer built for the Royal Navy. She was one of four destroyers ordered in 1918 from Swan Hunter and Wigham Richardson, Wallsend-on-Tyne under the 14th Order for Destroyers of the Emergency War Program of 1917–18. She was the second Royal Navy ship to carry the name, after the sloop in 1876. Like her sisters, she was completed too late to see action in the First World War.

Construction and design Wild Swan was one of seven Modified W-class destroyers that were completed after World War I, out of an original order for 38 ships issued in April 1918.Friedman 2009, pp. 170, 313–314. She was built by Swan Hunter at Wallsend on Tyne, being laid down in July 1918, launched on 17 May 1919 and completed on 14 November 1919.Preston 1971, pp. 109–110.

Pre-war service

On commissioning, the ship joined the 3rd Destroyer Flotilla, Atlantic Fleet, based at Port Edgar on the Firth of Forth and from March to July 1920, operated in the Baltic.Smith 1985, p. 236. She remained with the 3rd Flotilla when the Royal Navy's Destroyer Flotillas were reorganised from large flotillas of 16 destroyers and a leader to smaller units of eight ships and a leader in 1921.Preston 1971, pp. 35–36. The 3rd Destroyer Flotilla, including Wild Swan, transferred from the Atlantic Fleet to the Mediterranean Fleet in September 1922 as a result of the Chanak Crisis, a war scare between Britain and Turkey towards the end of the Greco-Turkish War. The 3rd Flotilla assisted in the evacuation of Greeks from Turkish territory after the end of the year, escorting transports carrying Greek troops.Preston 1971, p. 49. On 24–25 December 1923, she took part in the unsuccessful hunt for the French airship Dixmunde, searching the Gulf of Gabès,English 2019, p. 122. although Dixmunde had in fact been destroyed in an explosion off Sicily on 21 December.Robinson 1975, pp. 347–349. Wild Swan had her boilers retubed at Sheerness dockyard in June–July 1926. As a result of the outbreak of the Chinese Civil War the 3rd Destroyer Flotilla was despatched from the Mediterranean to China in order to protect British interests, arriving at Hong Kong on 15 October 1926.Preston 1971, p. 54.The Naval Review February 1930, pp. 97–99. Wild Swan was based at Jiujiang on the Yangtze river from January to June 1927, and on 26 March Wild Swan and the river gunboat intercepted the British steamer Kiangwo which had been seized by Chinese Nationalist troops to ferry troops up the Yangtze. After negotiation, the Nationalists released the vessel, paying compensation to the ship's owners.The Naval Review February 1930, pp. 105–106. The Flotilla re-assembled at Hong Kong on 1 May 1928 to prepare to return to home waters, but departure was delayed by the Jinan incident, a clash between Chinese Nationalist and Japanese troops, with the Flotilla not leaving until 8 July.The Naval Review February 1930, p. 116.

The 3rd Flotilla was re-equipped with A-class destroyers in 1930, and Wild Swan was placed in reserve.Manning 1961, p. 28. She was re-commissioned in 1931, joining the 8th Destroyer Flotilla on the China Station. Wild Swan transferred to the 1st Destroyer Flotilla based at Singapore in December 1934.Smith 1985, p. 237. The flotilla transferred to the Mediterranean during the Abyssinian crisis.Manning 1961, p. 29. The outbreak of the Spanish Civil War in July 1936 saw Wild Swan at Gibraltar and on 23 July she was patrolling in the Straits of Gibraltar when she was near missed by bombs dropped by Nationalist bombers, which resulted in Wild Swan firing back at the aircraft.Alberca 2015, pp. 49–50.

On 23 August 1937, Wild Swan was paid off into reserve, and remained in reserve at Portsmouth into 1939. She underwent a long refit at Chatham in late 1939 to update her equipment, including the fitting of anti-submarine detection equipment (ASDIC). This refit and consequent trials did not complete until December 1939.

Second World War

Early operations After her refit, Wild Swan was allocated to the 18th Destroyer Flotilla; however, in January 1940 she participated in trials on degaussing equipment, attached to the torpedo school, .Smith 1985, pp. 23–24. On 25 February 1940, Wild Swan joined the 18th Flotilla and commenced operations.Smith 1985, p. 26. On 4 March, Wild Swan and sister ship were dispatched from Plymouth to join the sloop in the search for a German U-boat that a merchant ship had reported sighting west of the Scilly Isles. Leith attacked a possible contact on that day, with Wild Swan joining in during the attacks on 5 March. Although depth charges brought up an oil slick, it was concluded that the contact was a false alarm, and the ships had been attacking a pre-existing wreck.Smith 1985, pp. 28–29.

Part of Britain's response was "Operation XD", with four destroyers (Wild Swan, , and ) embarking demolition teams in order to destroy key facilities at Dutch ports before they could be captured by the Germans. Wild Swan was tasked with landing its party at the Hook of Holland, arriving there on the afternoon of 10 May. She shelled German paratroops in a wood to the east of Hook of Holland on 11 May. She received damage to her starboard propeller while alongside at the Hook of Holland, and on 12 May was near missed by bombs from a German Junkers Ju 87 Stuka dive bomber which damaged the ship's condensers, before rescuing survivors from the passenger ship , which had been sunk by German dive bombers.Smith 1985, pp. 34–36, 46, 49–52.

Wild Swan entered Boulogne harbour at 20:25 hrs, shortly after and had left and was followed in by the destroyers and . As Venetia entered the harbour, she was shelled heavily by a German-manned shore battery and German tanks in an attempt to sink the ship in the entrance to the harbour and trap the remaining two ships. While Venetia was hit seven times, Venomous and Wild Swan managed to return fire with their 4.7 inch guns, suppressing the German shelling, so that Venetia could escape while Wild Swan and Venomous embarked troops (403 aboard Wild Swan and 500 aboard Venomous) before the two ships rejoined Venetia and returned to Dover.Smith 1985, pp. 65–72.Sebag-Montefiore 2015, pp. 208–209, 593–594.Winser 1999, p. 12.

On 17 June, Wild Swan landed a demolition party at St Malo, calling in at Jersey on the way there, where she requisitioned seven small merchant ships to take place in the evacuation of troops from St Malo, part of Operation Cycle.Winser 1999, pp. 44, 46. The 19th Flotilla was then based at Harwich, escorting convoys in the North Sea, and carrying out anti-invasion patrols, together with offensive strikes against enemy shipping.Smith 1985, p. 86. On 30 July, Wild Swan was carrying out an anti-invasion patrol with Whitshed and when Whitshed struck a mine. Wild Swan towed Whitshed stern first back to Harwich.Smith 1985, p. 92.

Later in September, Wild Swan was allocated to Operation Lucid, a plan to convert old oil tankers as Fire ships and use them to attack invasion barges in French ports. Wild Swan was part of the escort force on the first attempt to carry out Lucid, on the night of 25/26 September, where and were to be sacrificed, but this was abandoned because of unsuitable weather conditions and the poor condition of the fire ships. A second attempt on 2 October was cancelled due to poor weather. A third attempt was made on the night of 4/5 October, with War Nizam and Mytilus being sent against Calais and Oakfield against Boulogne. Wild Swan again formed part of the escort covering force, but unsuitable weather conditions again caused cancellation.Smith 1985, pp. 104–107.
