HMS Wivern (D66)

The second HMS ''Wivern'' (D66, later I66), was a Modified W-class destroyer of the British Royal Navy that saw service in World War II.

Building and commissioning

''Wivern'' was ordered in April 1918 as part of the 13th Order of the 1917-1918 Naval Programme. She was laid down on 19 August 1918 by J. Samuel White at Cowes, Isle of Wight, and launched on 16 April 1919. She was completed on 23 December 1919 and was commissioned into service the same day with the pennant number D66.

Service history

Before World War II

After entering service with the fleet in 1919, ''Wivern'' was assigned to the 3rd Destroyer Flotilla, serving with that flotilla in the Atlantic Fleet and Mediterranean Fleet before being decommissioned, transferred to the Reserve Fleet, and placed in reserve.

In 1939, ''Wivern'' was recommissioned as the fleet mobilised because of deteriorating diplomatic relations between the United Kingdom and Nazi Germany and was selected for assignment to the 16th Destroyer Flotilla based at Portsmouth in the event of war breaking out.

World War II

1939

After the United Kingdom entered World War II on 3 September 1939, ''Wivern''s assignment at Portsmouth was cancelled, and instead she was assigned to Western Approaches Command for convoy defence operations in the Western Approaches. On 5 September, she escorted Convoy GC 1 from the River Clyde in Scotland with the destroyers , , and . On 9 September she joined the destroyers and in escorting Convoy OB 2.

In October 1939, ''Wivern'' was transferred to the 16th Destroyer Flotilla under Commander-in-Chief, The Nore at Harwich for convoy escort and patrol duty in the North Sea. After the destroyer detonated a magnetic mine off Harwich and sank at on the evening of 21 November 1939, ''Wivern'' steamed through the area at high speed on 22 November in an attempt to detonate any other mines in the area and clear the area for ship traffic.

''Wivern'' continued her North Sea operations without further major incident through the end of 1939 and into 1940.

1940

''Wivern'' remained on convoy and patrol duty in the North Sea until May 1940, the month in which her pennant number was changed to I66. On 10 May, as the German invasion of the Netherlands, Belgium, Luxembourg, and France began, she was ordered to join the destroyer in Operation XD, consisting of demolition operations at Hook of Holland to prevent German forces from capturing important installations there intact. Accordingly, ''Wivern'' and ''Wild Swan'' went to Hook of Holland on 11 May, where ''Wivern'' took aboard the British diplomatic mission to the Netherlands for passage to Vlissingen. On 13 May, ''Wivern'' took part in Operation Ordnance, the evacuation of Allied personnel from Hook of Holland as German ground forces advanced through the Netherlands, suffering damage on 14 May during the operation. She then entered a dockyard in the United Kingdom for repairs.

After completion of repairs, ''Wivern'' returned to service with her flotilla at Harwich in July 1940 to continue her convoy and patrol duties in the North Sea. On 11 July 1940 she was attacked by German aircraft off Suffolk while escorting Convoy FN 19 near Aldeburgh Light, but she avoided damage by manoeuvering. As the threat of a German invasion of the United Kingdom grew, her duties included anti-invasion patrols, and on 3 August 1940 ''Wivern'', ''Wild Swan'', the light cruiser , the destroyers and , and the patrol vessels , , and patrolled together. On 7 September 1940 ''Wivern'' and ''Wild Swan'' took part in Operation Rival, screening ''Cardiff'' and the light cruiser as they patrolled off the coast of the Netherlands.

After Operation Rival, ''Wivern'' was transferred to Western Approaches Command with ''Wild Swan'', the destroyer leader , and the destroyer to serve in the 5th Escort Group, based at Liverpool, for convoy escort work in the North Atlantic Ocean. She carried out these duties for the rest of 1940 without major incident.

1941

''Wivern'' remained on convoy escort duty in the North Atlantic through the early weeks of 1941. On 26 February 1941, she deployed to escort ships of the 20th Destroyer Flotilla during Operation JH, a minelaying operation in the English Channel off Cape D'Antifer, France. She returned to her convoy duties after the conclusion of the operation.

In May 1941, ''Wivern'', ''Wild Swan'', and the destroyer deployed to Portsmouth. On 12 May, ''Wivern'', ''Wild Swan'', and the escort destroyers and escorted the heavy cruiser , which was undergoing a refit, and was moved from Portsmouth to Rosyth, Scotland, to avoid German air raids. On 14 May ''Wivern'' and ''Wild Swan'' escorted the Free French Forces on the first leg of ''Surcouf''s transatlantic voyage, separating from the submarine to return to the United Kingdom on reaching .

On 17 May 1941 the Royal Navy assigned ''Wivern'' to escort the military convoy WS 8X from the Clyde to Freetown, Sierra Leone, and to remain at Freetown after arrival to conduct convoy escort operations from there, but after the sank the British battlecruiser in the Battle of the Denmark Strait on 24 May and broke out into the open Atlantic accompanied by the , the convoy's departure and ''Wivern''s reassignment were postponed. ''Wivern'' instead was retained for duty in the Western Approaches pending developments related to the hunt for ''Bismarck'' and took passage with ''Vansittart'' and ''Wild Swan'' to Portsmouth to await further orders. Heavy units of the Home Fleet sank ''Bismarck'' in the North Atlantic on 27 May, and on 30 May the three destroyers returned to the Clyde. On 31 May, they set out from the Clyde as escorts for WS 8X along with the rest of the convoy's local escort, which also included the destroyers , , and , and the Royal Canadian Navy destroyer . On 3 June 1941, ''Wivern'' and the other ships of the local escort detached from WS 8X to return to the Clyde, leaving the convoy's protection to its ocean escort, which consisted of the aircraft carrier , the heavy cruiser , the light cruiser , and the armed merchant cruiser .

On 18 June 1941, ''Wivern'' once again was assigned to convoy escort duty at Freetown along with ''Vansittart'' and ''Wild Swan'', and the three destroyers steamed there that month to report for duty. From 10 to 13 July 1941, ''Wivern'', ''Wild Swan'', the destroyer , and the corvette reinforced the ocean escort – made up of the light cruiser and armed merchant cruiser – of the military convoy WS 9B during the final leg of its voyage to Freetown.

On 3 August 1941, ''Wivern'' departed Freetown bound for Gibraltar, where she entered the Royal Navy Dockyard for a refit. Upon its completion in September 1941, she was based at Gibraltar for Atlantic convoy escort operations, which she continued for the rest of 1941 without major incident.

1942

''Wivern'' remained on Atlantic convoy duty based at Gibraltar until 9 February 1942, when she departed Gibraltar with ''Wild Swan'', the destroyers , , and , and the sloops , , , and as the escort of Convoy SL 100 for its voyage to Freetown. Upon arriving at Freetown, she continued convoy escort duty based there.

In March 1942, the civil community of West Hartlepool in County Durham "adopted" ''Wivern'' in a Warship Week national savings campaign. On 3 May 1942, she departed Freetown with ''Boreas'', the heavy cruiser , the light cruiser , the seaplane carrier , the escort destroyer , and the Royal Netherlands Navy destroyer as the escort for Convoy WS 18, detaching with ''Boreas'' on 4 May to return to Freetown. On 30 June 1942, ''Wivern'', ''Boreas'', and the destroyer joined Convoy WS 20 at sea to reinforce its escort – consisting of ''Brilliant'', the destroyer , and the escort destroyer – and remained with the convoy until it arrived at Freetown on 2 July 1942.

''Wivern'' remained on escort duty at Freetown until October 1942, when she proceeded to Gibraltar with orders to support Operation Torch, the upcoming Allied amphibious landings in French Morocco and French Algeria scheduled for November 1942. In November, she began escorting convoys in the western Mediterranean, and on 10 November 1942 she was escorting Convoy TE 3 when she took part with ''Verity'', the destroyer , and the corvettes and in a depth-charge attack on the in the Mediterranean off Oran, Algeria, after ''U-660'' attacked the convoy; ''Lotus'' and ''Starwort'' were credited with sinking the submarine on 12 November 1942 at .

''Wivern'' continued on convoy escort duty based at Gibraltar through the end of 1942 and into 1943.

1943

''Wivern'' was still based at Gibraltar on western Mediterranean convoy escort duty on 22 February 1943, when she came to the assistance of the Royal Canadian Navy corvette , which had struck a German mine and was sinking east of Gibraltar off Cape Espartel and was sinking at with the loss of her commanding officer and 12 other members of her crew. While rescuing ''Weyburn''s survivors, ''Wivern'' suffered severe structural damage either from the detonation of another mine or when depth charges aboard ''Weyburn'' exploded as she sank.

In March 1943, ''Wivern'' was towed to the United Kingdom for repairs, and in April 1943 she was decommissioned at Plymouth and entered the Royal Navy Dockyard there for extensive repairs – including to her propulsion plant, which the explosion had lifted off its mountings – and a refit that included the replacement of her forward 4.7-inch (120-mm) with a twin 6-pounder British Army gun for use against motor torpedo boats. She was in dockyard hands for the next 20 months.

1944-1945

With her repairs and refit finally complete, ''Wivern'' underwent post-refit acceptance trials in September 1944 and recommissioned that month for assignment back to the Nore for service with the Harwich Escort Force. In October 1944, she took up her duties at Harwich, which were focused on nightly patrols to counter the operations of German motor torpedo boats – S-boats, known to the Allies as "E-boats" – in the North Sea. In November 1944, she began escort duty for North Sea convoys during their voyages between the Thames Estuary and Rosyth.

In January 1945, ''Wivern'' was escorting a convoy when she suffered structural damage during a Force 12 gale. She underwent repairs at the Royal Navy Dockyard at Rosyth and returned to duty in February 1945.

''Wivern'' was part of the escort of Convoy FS 56 on its voyage from Rosyth to the Thames Estuary on 14 March 1945 when the attacked, torpedoing and sinking the Danish cargo ship ''Magne'' off St. Abbs, Scotland, near the Firth of Forth. As ''Wivern'' rescued ''Magne''s survivors, the South African Navy frigate , a new ship that had left the River Tyne only four hours earlier bound for Scapa Flow in the Orkney Islands and then for antisubmarine warfare training at Tobermory on the Isle of Mull, arrived on the scene to assist. ''Natal'' detected a submerged submarine with her ASDIC equipment, which was more modern and advanced than that on ''Wivern''. ''Natal'' attacked, firing two Squid anti-submarine mortar salvos of six depth bombs each. After the second attack, ''Natal'' lost ASDIC contact with ''U-714'' and oil and a metal tank rose to the surface at . ''Natal'' then proceeded to Scapa Flow.

A Royal Navy antisubmarine hunter-killer group led by the frigate arrived and depth-charged the position, bringing more flotsam from the submarine to the surface. ''Wivern'', however, claimed a share of the kill after depth-charging an oil slick to the south under the assumption that it was oil from ''U-714'', which ''Wivern''s crew believed had been only been damaged by ''Natal'' and was attempting to escape. Although some controversy surrounds credit for the sinking, naval authorities determined that ''Natal'' had sunk ''U-714'' with the loss of the submarine's entire crew of 50 men and gave ''Natal'' sole credit.

''Wivern'' continued her convoy escort duties in the North Sea until the surrender of Germany in early May 1945. She then deployed to support Allied reoccupation forces in Norway and to transport Allied personnel.

Decommissioning and disposal

''Wivern'' was decommissioned and laid up at Rosyth later in the summer of 1945, and by October 1945 she no longer appeared on the Royal Navys active list. Later placed on the disposal list, she was sold to Metal Industries on 18 February 1947 for scrapping. She was towed to the breaker's yard at Charlestown, Fife, Scotland, in October 1948.
