HMS Collingwood was a dreadnought battleship built for the Royal Navy in the first decade of the 20th century. She spent her whole career assigned to the Home and Grand Fleets and often served as a flagship. Prince Albert (later King George VI) spent several years aboard the ship before and during World War I. At the Battle of Jutland in May 1916, Collingwood was in the middle of the battleline and lightly damaged a German battlecruiser. Other than that battle, and the inconclusive action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war; she was reduced to reserve and used as a training ship before being sold for scrap in 1922.

Design and description The design of the St Vincent class was derived from that of the previous , with a slight increase in size, armour and more powerful guns, among other more minor changes. Collingwood had an overall length of , a beam of ,Burt, pp. 75–76 and a normal draught of .Preston 1972, p. 125 She displaced at normal load and at deep load. In 1911 her crew numbered 758 officers and ratings.Burt, p. 76

Collingwood was powered by two sets of Parsons direct-drive steam turbines, each driving two shafts, using steam from eighteen Yarrow boilers. The turbines were rated at and were intended to give the ship a maximum speed of . During her full-power, eight-hour sea trials on 17 January 1910, she only reached a top speed of from . Collingwood carried enough coal and fuel oil to give her a range of at a cruising speed of .Burt, pp. 76, 80

Armament and armour The St Vincent class was equipped with ten breech-loading (BL) 12-inch (305 mm) Mk XI guns in five twin-gun turrets, three along the centreline and the remaining two as wing turrets. The secondary, or anti-torpedo boat, armament comprised twenty BL 4-inch (102 mm) Mk VII guns. Two of these guns were each installed on the roofs of the fore and aft centreline turrets and the wing turrets in unshielded mounts, and the other ten were positioned in the superstructure. All guns were in single mounts. The ships were also fitted with three 18-inch (450 mm) torpedo tubes, one on each broadside and the third in the stern.

The St Vincent-class ships had a waterline belt of Krupp cemented armour (KC) that was thick between the fore and aftmost barbettes, reducing to a thickness of before it reached the ships' ends. Above this was a strake of armour thick. Transverse bulkheads inches thick terminated the thickest parts of the waterline and upper armour belts once they reached the outer portions of the endmost barbettes.Burt, pp. 76, 78; Parkes, p. 503

The three centreline barbettes were protected by armour thick above the main deck that thinned to below it. The wing barbettes were similar except that they had 10 inches of armour on their outer faces. The gun turrets had faces and sides with roofs. The three armoured decks ranged in thicknesses from . The front and sides of the forward conning tower were protected by 11-inch plates, although the rear and roof were 8 inches and 3 inches thick, respectively.Burt, pp. 76, 78; Parkes, p. 504

Alterations The guns on the forward turret roof were removed in 1911–1912 and the upper forward pair of guns in the superstructure were removed in 1913–1914. In addition, gun shields were fitted to all guns in the superstructure and the bridge structure was enlarged around the base of the forward tripod mast. During the first year of the war, a fire-control director was installed high on the forward tripod mast. Around the same time, the base of the forward superstructure was rebuilt to house eight 4-inch guns and the turret-top guns were removed, which reduced her secondary armament to a total of fourteen guns. In addition, a pair of 3-inch anti-aircraft (AA) guns were added.Burt, p. 81

By April 1917, Collingwood mounted thirteen 4-inch anti-torpedo boat guns as well as single 4-inch and 3-inch AA guns. Approximately of additional deck armour had been added after the Battle of Jutland. Before the end of the war the AA guns were moved from the deckhouse between the aft turrets to the stern and the stern torpedo tube was removed. In 1918, a high-angle rangefinder was fitted and flying-off platforms were installed on the roofs of the fore and aft turrets.

Construction and career

Collingwood, named after Vice-Admiral Cuthbert Collingwood,Silverstone, p. 223 was ordered on 26 October 1907. She was laid down at Devonport Royal Dockyard on 3 February 1908, launched on 7 November 1908 and completed in April 1910. Including her armament, the ship's cost is quoted at £1,680,888 or £1,731,640.Parkes, p. 503

On 19 April 1910, Collingwood was commissioned and assigned to the 1st Division of the Home Fleet under the command of Captain William Pakenham.Brady, Part One, p. 29 She joined other members of the fleet in regular peacetime exercises, and on 11 February 1911 damaged her bottom plating on an uncharted rock off Ferrol. On 24 June the ship was present at the Coronation Fleet Review for King George V at Spithead.Burt, p. 86 Pakenham was relieved by Captain Charles Vaughan-Lee on 1 December. On 1 May 1912, the 1st Division was renamed the 1st Battle Squadron. On 22 June, Vaughan-Lee was transferred to the battleship and Captain James Ley assumed command; Vice-Admiral Stanley Colville hoisted his flag in Collingwood as commander of the 1st Battle Squadron. The ship participated in the Parliamentary Naval Review on 9 July at Spithead before beginning a refit late in the year. In March 1913, Collingwood and the 1st Battle Squadron undertook a port visit to Cherbourg, France.Burt, p. 88 Midshipman Prince Albert (later King George VI) was assigned to the ship on 15 September 1913.Judd, p. 28 Collingwood hosted Albert's older brother, Edward, Prince of Wales, during a short cruise on 18 April 1914. She became a private ship when Colville hauled down his flag on 22 June.

World War I Between 17 and 20 July 1914, Collingwood took part in a test mobilisation and fleet review as part of the British response to the July Crisis. Arriving in Portland on 27 July, she was ordered to proceed with the rest of the Home Fleet to Scapa Flow two days later to safeguard the fleet from a possible German surprise attack.Massie, pp. 15–20 In August 1914, following the outbreak of World War I, the Home Fleet was reorganised as the Grand Fleet, and placed under the command of Admiral John Jellicoe.Preston 1985, p. 32 Most of it was briefly based (22 October to 3 November) at Lough Swilly, Ireland, while the defences at Scapa were strengthened. On the evening of 22 November 1914, the Grand Fleet conducted a fruitless sweep in the southern half of the North Sea; Collingwood stood with the main body in support of Vice-Admiral David Beatty's 1st Battlecruiser Squadron. The fleet was back in port in Scapa Flow by 27 November.Jellicoe, pp. 163–165 The 1st Battle Squadron cruised north-west of the Shetland Islands and conducted gunnery practice on 8–12 December. Four days later, the Grand Fleet sortied during the German raid on Scarborough, Hartlepool and Whitby, but failed to make contact with the High Seas Fleet. Collingwood and the rest of the Grand Fleet conducted another sweep of the North Sea on 25–27 December.Brady, Part One, p. 32; Jellicoe, pp. 172, 179, 183–184

The Grand Fleet, including Collingwood, conducted gunnery drills on 10–13 January 1915 west of Orkney and Shetland. On the evening of 23 January, the bulk of the Grand Fleet sailed in support of Beatty's battlecruisers, but Collingwood and the rest of the fleet did not participate in the ensuing Battle of Dogger Bank the following day.Jellicoe, pp. 190, 194–196 The ship sailed for Portsmouth Royal Dockyard on 2 February to begin a brief refit and returned on 18 February.Brady, Part One, p. 32 On 7–10 March, the Grand Fleet conducted a sweep in the northern North Sea, during which it conducted training manoeuvres. Another such cruise took place on 16–19 March.Jellicoe, p. 206 From 25 March to 14 April 1915, Rear-Admiral Hugh Evan-Thomas temporarily hoisted his flag aboard Collingwood.Brady, Part One, p. 33 On 11 April, the Grand Fleet conducted a patrol in the central North Sea and returned to port on 14 April; another patrol in the area took place on 17–19 April, followed by gunnery drills off Shetland on 20–21 April.Jellicoe, pp. 211–212

The Grand Fleet conducted sweeps into the central North Sea on 17–19 May and 29–31 May without encountering any German vessels. During 11–14 June the fleet conducted gunnery practice and battle exercises west of Shetland.Jellicoe, pp. 217, 218–219, 221–222 Collingwood was briefly docked at Invergordon from 23 to 25 June. King George V inspected the ship on 8 July, and the Grand Fleet conducted training off Shetland beginning three days later.Jellicoe, p. 228 Rear-Admiral Ernest Gaunt temporarily used Collingwood as his flagship from 24 August to 24 September and from 10 December to 16 January 1916.Brady, Part One, pp. 33–34 On 2–5 September 1915, the fleet went on another cruise in the northern end of the North Sea and conducted gunnery drills. Throughout the rest of the month, the Grand Fleet conducted numerous training exercises. The ship, together with the majority of the Grand Fleet, conducted another sweep into the North Sea from 13 to 15 October. Almost three weeks later, Collingwood participated in another fleet training operation west of Orkney during 2–5 November.Jellicoe, pp. 243, 246, 250, 253 On 21 November, she sailed for Devonport Royal Dockyard for a minor overhaul and arrived back at Scapa on 9 December.Brady, Part One, p. 34

The Grand Fleet departed for a cruise in the North Sea on 26 February 1916; Jellicoe had intended to use the Harwich Force to sweep the Heligoland Bight, but bad weather prevented operations in the southern North Sea. As a result, the operation was confined to the northern end of the sea. Another sweep began on 6 March, but had to be abandoned the following day as the weather grew too severe for the escorting destroyers. On the night of 25 March, Collingwood and the rest of the fleet sailed from Scapa Flow to support Beatty's battlecruisers and other light forces raiding the German Zeppelin base at Tondern. By the time the Grand Fleet approached the area on 26 March, the British and German forces had already disengaged and a strong gale threatened the light craft, so the fleet was ordered to return to base. On 21 April, the Grand Fleet conducted a demonstration off Horns Reef to distract the Germans while the Russian Navy relaid its defensive minefields in the Baltic Sea. The fleet returned to Scapa Flow on 24 April and refuelled before proceeding south in response to intelligence reports that the Germans were about to launch a raid on Lowestoft. The Grand Fleet arrived in the area after the Germans had withdrawn. On 2–4 May, the fleet conducted another demonstration off Horns Reef to keep German attention focused on the North Sea.Jellicoe, pp. 271, 275, 279–280, 284, 286–290

Battle of Jutland

In an attempt to lure out and destroy a portion of the Grand Fleet, the German High Seas Fleet, composed of 16 dreadnoughts, 6 pre-dreadnoughts, 6 light cruisers, and 31 torpedo boats, departed the Jade Bight early on the morning of 31 May. The fleet sailed in concert with Rear Admiral Franz von Hipper's five battlecruisers and supporting cruisers and torpedo boats. The Royal Navy's Room 40 had intercepted and decrypted German radio traffic containing plans of the operation. In response, the Admiralty ordered the Grand Fleet, totalling some 28 dreadnoughts and 9 battlecruisers, to sortie the night before to cut off and destroy the High Seas Fleet.Tarrant, pp. 54–55, 57–58 Collingwood was the eighteenth ship from the head of the battle line after the Grand Fleet deployed for battle.
