HMS Denbigh Castle

Template:Infobox ship imageTemplate:Infobox ship careerTemplate:Infobox ship characteristics

HMS Denbigh Castle (K696) was one of 44 Template:Sclass2s built for the Royal Navy during World War II. The ship was completed at the end of 1944 and was assigned to the 7th Escort Group at the beginning of 1945. While escorting her first and only Arctic convoy to Russia, she claimed to have shot down a German torpedo bomber. Denbigh Castle was torpedoed in early 1945 by the Template:GS, with the loss of 11 men, near the Soviet coast. The ship was beached in an effort to save her, but she was pulled off by the ebbing tide and capsized. Her wreck was declared a total loss.

Design and description

The Castle-class corvette was a stretched version of the preceding Template:Sclass2, enlarged to improve seakeeping and to accommodate modern weapons. The ships displaced Template:Convert at standard load and Template:Convert at deep load. They had an overall length of Template:Convert, a beam of Template:Convert and a deep draught of Template:Convert. They were powered by a pair of triple-expansion steam engines, each driving one propeller shaft using steam provided by two Admiralty three-drum boilers. The engines developed a total of Template:Convert and gave a maximum speed of Template:Convert. The Castles carried enough fuel oil to give them a range of Template:Convert at Template:Convert. The ships' complement was 99 officers and ratings.<ref>Lenton, p. 297</ref>

The Castle-class ships were equipped with a single [[QF 4 inch Mk XVI naval gun|QF Template:Convert Mk XVI gun]] forward, but their primary weapon was their single three-barrel Squid anti-submarine mortar. This was backed up by one depth charge rail and two throwers for 15 depth charges. The ships were fitted with two twin and a pair of single mounts for [[Oerlikon 20 mm cannon|Template:Convert Oerlikon]] light AA guns.<ref>Chesneau, p. 63; Lenton, p. 297</ref> Provision was made for a further four single mounts if needed. They were equipped with Type 145Q and Type 147B ASDIC sets to detect submarines by reflections from sound waves beamed into the water. A Type 277 search radar and a HF/DF radio direction finder rounded out the Castles' sensor suite.<ref>Goodwin, p. 3</ref>

Construction and career

Denbigh Castle, the only ship of her name to serve in the Royal Navy,<ref>Colledge, p. 94</ref> was ordered on 19 December 1942 and laid down by John Lewis & Sons at their shipyard in Aberdeen, Scotland, on 30 September 1943. The ship was launched on 5 August 1944 and completed on 30 December 1944. She arrived at Tobermory, Mull, Scotland, on 12 January 1945 to begin training at the Royal Navy's Anti-Submarine Training School, Template:HMS. Having completed training, Denbigh Castle arrived at Scapa Flow on 29 January to join the 7th Escort Group.<ref>Goodwin, p. 139</ref>

Commanded by Lieutenant Commander Graham Butcher, the ship escorted Convoy JW 64 to Murmansk at the beginning of February. On the 7th, Denbigh Castle claimed to have shot down a German torpedo bomber.<ref>Goodwin, p. 140</ref> Almost a week later, the ship was torpedoed by U-992 as the convoy entered the Kola Inlet<ref>Rohwer, p. 392</ref> at 00:13 on 13 February; the corvette's radar had picked up the submarine at a range of Template:Convert, but had not identified her due to the confused radar returns and darkness. The torpedo struck the bow and the crew thought that the ship had struck a mine. The explosion killed eleven ratings and threw the four-inch gun onto the Squid platform behind it. The remaining bow structure sagged downwards, although Denbigh Castle was in no danger of sinking. The destroyer Template:HMS transferred her medical officer over and the corvette Template:HMS came alongside around 00:45 to receive casualties, and Butcher ordered as many ratings aboard her as he thought he could spare. Bluebell began towing Denbigh Castle at 02:05 and reached a maximum speed of Template:Convert, Serapis screening the ships during the tow.<ref>Goodwin, pp. 140, 480–81</ref>

The Template:Ship came alongside at 04:30 to transfer a Template:Convert salvage pump as the corvette was still taking on water. At 05:01, Butcher ordered all remaining hands aboard the Soviet ship because Denbigh Castle was slowly sinking by the bow, only the officers remaining aboard. BuresvestnikTemplate:'s captain, not wanting the corvette to founder in the channel, took over the tow at 06:15, by which time her stern was nearly out of the water. Denbigh Castle was beached at 07:30 at Bolshaya Volokovaya Bay near Vaenga; Buresvestnik then pushed her stern around. The ship began to slowly list with the ebbing tide and the officers abandoned her at 09:05; five minutes later she capsized and slid into deeper water. The intense cold made later efforts to retrieve or destroy secret documents and equipment still aboard extremely difficult, but the diving team from the light cruiser Template:HMS did manage to demolish the radar office. In recognition of her service, Denbigh Castle was awarded the battle honour Arctic 1945.<ref>Goodwin, pp. 139, 141–42</ref>
