HMS Viscount (D92)

HMS Viscount was a V-class destroyer (Thornycroft V and W class) of the British Royal Navy that saw service in the final months of World War I and in World War II.

Construction and commissioning
Viscount, the first Royal Navy ship of the name, was ordered either on 30 June 1916 or in July 1916 (sources differ) as part of the 9th Order of the 1916–1917 Naval Programme and was laid down by John I. Thornycroft & Company at Woolston, Hampshire, England, on 20 December 1916. Although broadly similar, Viscount was one of only two V-Class destroyers built by Thornycrofts. HMS Viscount differed in a number of ways to other V-Class destroyers and was notably faster. Launched on 29 December 1917, she was completed on 4 March 1918 and commissioned the same day. Her original pennant number, F99, was changed first to G06 and then in April 1918 to G24; it was changed to D92 during the interwar period.

World War I
Upon completion, Viscount was assigned to the Grand Fleet, based at Scapa Flow in the Orkney Islands, in which she served for the rest of World War I. Viscount rapidly gained a reputation as an exceptionally fast ship and successfully attacked and sank at least one German U-Boat which was caught on the surface. HMS Viscount was signalled to attack at full speed. The U-Boat spoilt the aim of Viscounts forward battery by submerging full-speed astern. Viscount steamed over the U-Boat and destroyed it by depth-charges. HMS Viscount also participated in several cruises/escorts to Murmansk and Archangel during this period. Other actions included the interception and seizing of Bolshevik-controlled Russian warships in support of White Russian forces.

Interwar
After the conclusion of World War I, Viscount served in the Atlantic Fleet. In 1921 she joined the light cruisers HMS Caledon (D53), HMS Castor (1915), HMS Cordelia (1914), and HMS Curacoa (D41) and the destroyers HMS Vanquisher (D54), HMS Vectis (D51), HMS Venetia (D53), HMS Viceroy (D91), HMS Violent (D57), HMS Winchelsea (D46), and HMS Wolfhound (D56) in a Baltic Sea cruise, departing the United Kingdom on 31 August 1921. The ships crossed the North Sea and transited the Kaiser Wilhelm Canal to enter the Baltic, where they called at Danzig in the Free City of Danzig; Memel in the Klaipėda Region; Liepāja, Latvia; Riga, Latvia; Tallinn, Estonia; Helsinki, Finland; Stockholm, Sweden; Copenhagen, Denmark; Gothenburg, Sweden; and Kristiania, Norway, before crossing the North Sea and ending the voyage at Port Edgar, Scotland, on 15 October 1921.

Viscount later served in the Mediterranean Fleet before being assigned to duties in home waters. She was attached to the 1st Submarine Flotilla in 1938.

1939–1940
When the United Kingdom entered World War II on 3 September 1939, Viscount was deployed with the 19th Destroyer Flotilla, based at Plymouth, for convoy escort and patrol duty in the English Channel and Southwestern Approaches. In January 1940, she was reassigned to the Western Approaches Command but continued her escort and patrol operations from Plymouth. On 7 January 1940, she and the destroyer HMS Vanoc (H33) relieved two French warships as escort for Convoy HG 13 during the final leg of its voyage from Gibraltar to the United Kingdom; the destroyers HMS Venetia (D53) and HMS Volunteer (D71) and the trawler HMS Arctic Ranger (FY186) joined the escort on 8 January 1940, and Viscount detached from it on 10 January. On 18 February 1940, Viscount and Vanquisher relieved a French warship as the escort for Convoy HG 18 during the final portion of its voyage from Gibraltar to Liverpool, detaching to return to Plymouth when it arrived at Liverpool on 19 February 1940. On 8 April 1940, Viscount, the destroyers HMS Vimy (D33) and HMS Witch (D89), and the HMS Rochester (L50) relieved a French warship as the escort of Convoy HG 25F for the last leg of its voyage from Gibraltar to Liverpool; although Vimy and Witch detached the next day, Viscount and Rochester stayed with the convoy until arrived at Liverpool on 11 April 1940. In April, Western Approaches Command moved its headquarters to Liverpool, and as a result Viscount's base was changed from Plymouth to Liverpool.

In May 1940, Viscount's pennant number was changed to I92. That month, she was assigned to operations related to the Norwegian Campaign in the aftermath of the April 1940 German invasion of Norway and Denmark. On 17 May 1940, she joined the destroyers HMS Diana (H49) and HMS Veteran (D72) in escorting the aircraft carrier HMS Glorious from the River Clyde in Scotland to the Norwegian coast. On 7 June 1940, Viscount, the destroyers HMS Antelope (H36), HMS Witherington (D76) and HMS Wolverine (D78), and the escort destroyer HMS Atherstone (L05) departed the United Kingdom to meet a convoy of troopships that had been delayed by fog. Later that day, the destroyers rendezvoused with the troopships – carrying Allied personnel evacuated from Norway as the campaign there ended in the German conquest of the country – and the repair ship HMS Vindictive (1918) and took them under escort to the Clyde. The convoy came under attack by German aircraft on 8 June 1940, but the escorts drove the German planes off.

Viscount returned to her North Atlantic convoy escort duty in July 1940. In September 1940 she detached from it to join Witherington and the destroyers HMS Vansittart (D64) and HMS Whitehall (D94) in escorting the auxiliary minelayers HMS Menestheus (M93), HMS Port Napier (M32), HMS Port Quebec (M59), and HMS Southern Prince (M47) while they laid mines in the Northern Barrage in Operation SN42.

Viscount then went back to convoy operations, and she was part of the escort of Convoy HG 47 – bound from Gibraltar to the United Kingdom – along with the HMS Folkestone (L22) and  HMS Gentian (K90) in November 1940. Detaching from HG 47, she rendezvoused with Convoy HX 90 – 41 ships bound from Halifax, Nova Scotia, Canada, to Liverpool – as its escort on 1 December 1940. Later that day, HX 90 came under attack by the first of six German submarines, which sank 10 of its ships on 1 and 2 December. The sinkings stopped only after Viscount and the Royal Canadian Navy destroyer HMCS St. Laurent (H83) conducted 13 depth-charge attacks on asdic contacts over the course of four hours on 2 December, keeping the submarines submerged and unable to attack until HX 90 had left the area. On 2 December, Viscount rescued survivors from some of HX 90's lost ships, picking up some of the 21 survivors from the armed merchant cruiser HMS Forfar (F30), which the GS U-99 (1940) had torpedoed and sunk 500 nmi west of Ireland at 54.58333°N, -18.3°W with the loss of 172 lives; 16 survivors of the British merchant ship Kavak, which the GS U-100 (1940) had torpedoed and sunk during the night of 1–2 December about 340 nmi west of Bloody Foreland at 55°N, -19.5°W; 36 survivors of the British merchant ship Goodleigh, which the GS U-52 (1939) had torpedoed and sunk on 2 December 367 nmi west of Bloody Foreland at 55.03333°N, -18.75°W; and 27 survivors of the Ellerman Lines cargo ship SS Tasso, which U-52 had torpedoed and sunk on 2 December about 340 nm west of Bloody Foreland at 55.05°N, -18.06667°W. Viscount then escorted HX 90 the rest of the way to Liverpool, where it arrived on 5 December 1940.

1941–1942
Viscount continued on convoy escort duty in the North Atlantic until June 1941, when she began conversion to a Long-Range Escort at Liverpool. With the conversion complete, she underwent post-conversion acceptance trials and, having passed them, performed work-ups in December 1941 to prepare for her return to convoy duty, which she did later that month.

In March 1942, Viscount was "adopted" by the civilian community of Chislehurst and Sidcup in Kent in a Warship Week national savings campaign. In April 1942, she was reassigned to the 6th Escort Group, in which she joined the corvettes HMS Rose (K102) and HMS Potentilla (K214) and the Royal Norwegian Navy corvettes HNOMS Andenes and HNOMS Eglantine. In May 1942, she escorted Convoy SC 83 with the group. By June–July 1942, she had had Type 271 surface warning radar and a Hedgehog antisubmarine mortar installed.

On 13 August 1942, Viscount was part of the escort of Convoy ONS 122 when it came under a series of sustained attacks by German submarines of the "Lohs" group. On 23 August, she intercepted communications from one of the submarines, got a fix on its location, detected it with asdic after it submerged, and attacked it. By the time attacks on ONS 122 ended, it had lost four ships and its escorts had damaged two German submarines.

In October 1942, Viscount was part of the escort of Convoy SC 1 CW, which came under attack by 10 German submarines of the "Wotan" (Wōden) group. On 15 October, while defending the convoy, Viscount detected the submarine U-607 on radar and attacked her unsuccessfully. Viscount then rammed and sank the submarine U-661 at 53.7°N, -35.93333°W, which went down with the loss of her entire crew of 44. Viscount suffered significant damage in the ramming and had to detach from the convoy and proceed to the United Kingdom for repairs.

1943–1945
Viscount's repairs were completed in February 1943, and she rejoined the 6th Escort Group that month in time to join the escort of Convoy ONS 165, which came under attack from German submarines of the "Taifun" ("Typhoon") group. In defense of the convoy, she depth-charged and rammed the submarine GS U-201 in the North Atlantic at 50.83333°N, -40.83333°W. U-201 sank with the loss of her entire crew of 49, and Viscount again suffered significant damage, requiring repairs that lasted through April 1943.

In May 1943, Viscount returned to North Atlantic convoy duty. While escorting Convoy ONS 6 with the 6th Escort Group on 8 May 1943, she got a radio direction-finding fix on a German submarine and closed with it, sighting it at a range of 7000 yd. The submarine submerged, and Viscount attacked it with depth charges, but without success.

Over the course of the summer of 1943, Viscount was detached for Operation Derange, consisting of offensive antisubmarine operations in the Bay of Biscay in which aircraft and ships cooperated in attacks on German submarines transiting the bay between their bases in German-occupied France and the Atlantic shipping routes. In September 1943, she took part in Operation Alacrity, joining the escort aircraft carrier HMS Fencer (D64), the destroyers HMS Inconstant (H49), HMS Whitehall (D94), and HMS Wrestler (D35), and the Polish Navy destroyers ORP Garland and ORP Burza in forming the 8th Support Group to escort military convoys to the Azores as the Allies set up air bases there. She continued operations in support of Alacrity into October 1943.

Viscount returned to Atlantic convoy duty in October 1943, continuing it without further major incident into the early weeks of 1945, when she also began convoy escort operations in British coastal waters. In order to free up her crew members to man newer, more modern escort ships, she was withdrawn from operations in February 1945 and decommissioned in March 1945.

Decommissioning and disposal
Viscount was sold on 20 March 1945 to BISCO for scrapping by Clayton and Davie at Dunston. She arrived at the shipbreaker's yard on 27 May 1947.
