HMS Vanguard was one of three dreadnought battleships built for the Royal Navy in the first decade of the 20th century. She spent her career assigned to the Home and Grand Fleets. Aside from participating in the Battle of Jutland in May 1916 and the inconclusive action of 19 August several months later, her service during World War I mostly consisted of routine patrols and training in the North Sea.

Shortly before midnight on 9 July 1917 at Scapa Flow, Vanguard suffered a series of magazine explosions. She sank almost instantly, killing 843 of the 845 men aboard. The wreck was heavily salvaged after the war, but was eventually protected as a war grave in 1984. It was designated as a controlled site under the Protection of Military Remains Act 1986, and diving on the wreck is generally forbidden.

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 minor changes. Vanguard 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 1910 her crew numbered 753 officers and ratings.Burt, p. 76

Vanguard was powered by two sets of Parsons direct-drive steam turbines, each driving two shafts, using steam from eighteen Babcock & Wilcox boilers. The turbines were rated at and intended to give the ship a maximum speed of . During her sea trials on 17 December 1909, she unofficially reached a top speed of from , although she must have been lightly loaded to reach this speed. Vanguard carried enough coal and fuel oil to give her a range of at a cruising speed of .Burt, pp. 76, 80

The St Vincent class was equipped with ten breech-loading (BL) Mk XI guns in five twin-gun turrets, three along the centreline and the remaining two as wing turrets. The centreline turrets were designated 'A', 'X' and 'Y', from front to rear, and the port and starboard wing turrets were 'P' and 'Q' respectively. The secondary, or anti-torpedo boat armament, comprised twenty BL 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 were protected by a waterline armoured belt thick that extended between the end barbettes. Their decks ranged in thickness between with the thickest portions protecting the steering gear in the stern. The main battery turret faces were thick, and the turrets were supported by barbettes thick.

Modifications

The guns on the forward turret roof were removed in 1910–1911. About three years later, gun shields were fitted to most of the 4-inch guns in the superstructure and the bridge structure was enlarged around the base of the forward tripod mast. During the first year of World War I, 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 (76 mm) anti-aircraft (AA) guns were added. A fire-control director was installed high on the forward tripod mast before the Battle of Jutland in May 1916.Brooks, p. 168 Approximately of additional deck armour were added afterwards. By April 1917, Vanguard mounted thirteen 4-inch anti-torpedo boat guns as well as one 4-inch and one 3-inch AA gun.Burt, p. 81

Construction and career

Vanguard, the eighth ship of that name to serve in the Royal Navy,Colledge, p. 369 was ordered on 6 February 1908. She was laid down by Vickers Armstrong at their Barrow-in-Furness shipyard on 2 April 1908, launched on 22 February 1909, and completed on 1 March 1910. Including armament, the ship cost about £1.6 million. Vanguard was commissioned on 1 March 1910, under the command of Captain John Eustace, and assigned to the 1st Division of the Home Fleet. She was present in Torbay when King George V visited the fleet in late July. Vanguard also participated in the Coronation Fleet Review at Spithead on 24 June 1911 and she trained with the Atlantic Fleet the following month before beginning a refit.Burt, p. 86 Captain Arthur Ricardo relieved Eustace on 23 September.

The ship was recommissioned on 28 March 1912 and rejoined the 1st Division shortly before it was renamed the 1st Battle Squadron on 1 May. She participated in exercises with the 1st Fleet in October. Vanguard was refitted in December, with new bilge keels being installed. On 5 June 1913, Captain Cecil Hickley replaced Ricardo upon the latter's promotion to commodore, second class.

World War I Between 17 and 20 July 1914, Vanguard 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 forestall a possible surprise attack by the Imperial German Navy.Massie, p. 19 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 On 1 September, the Grand Fleet was anchored at Scapa Flow when the light cruiser spotted a suspected German submarine, provoking a panic across the fleet. Vanguard also spotted what was believed to be a periscope and opened fire, but the whole incident proved to be a false alarm.Naval Staff Monograph No. 24, pp. 40–41 Submarine scares such as this caused the fleet to be briefly (22 October to 3 November) based at Lough Swilly, Ireland, while the defences at Scapa were strengthened. On the evening of 22 November, the Grand Fleet conducted a fruitless sweep in the southern half of the North Sea; Vanguard 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. 143, 156, 163–165In his 1919 book, Jellicoe generally only named specific ships when they were undertaking individual actions. Usually he referred to the Grand Fleet as a whole, or by squadrons and, unless otherwise specified, this article assumes that Vanguard is participating in the activities of the Grand Fleet. The 1st Battle Squadron cruised north-west of the Shetland Islands and exercised their guns 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. Vanguard and the rest of the Grand Fleet made another sweep of the North Sea on 25–27 December.Jellicoe, pp. 172, 179, 183–184

Jellicoe's ships, including Vanguard, conducted gunnery drills west of Orkney and Shetland on 10–13 January 1915.Jellicoe, p. 190 On the evening of 23 January, the bulk of the Grand Fleet sailed in support of Beatty's battlecruisers,Monograph No. 12, p. 224 but they were too far away to participate in the ensuing Battle of Dogger Bank the following day. On 7–10 March, the Grand Fleet made a sweep in the northern North Sea, during which it conducted training manoeuvres. Another such cruise took place on 16–19 March. On 11 April, the fleet patrolled 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. 194–196, 206, 211–212

The Grand Fleet swept the central North Sea on 17–19 May and 29–31 May without encountering any German vessels. During 11–14 June the fleet practised gunnery and battle exercises west of Shetland,Jellicoe, pp. 217–219, 221–222 and on 11 July there was more training off Shetland. On 2–5 September, 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 was performing numerous training exercises before making another sweep into the North Sea on 13–15 October. Almost three weeks later, Vanguard participated in another fleet training operation west of Orkney during 2–5 November.Jellicoe, pp. 228, 243, 246, 250, 253

Captain James Dick relieved Hickley on 22 January 1916. The fleet departed for a cruise in the North Sea on 26 February; 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, Vanguard 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.Jellicoe, pp. 271, 275, 279–280 In April the ship was transferred to the 4th Battle Squadron. On 21 April, the Grand Fleet conducted a demonstration off Horns Reef to distract the Germans while the Russian Navy re-laid 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. 284, 286–290

Battle of Jutland

In an attempt to lure out and destroy a portion of the Grand Fleet, the High Seas Fleet, composed of 16 dreadnoughts, 6 pre-dreadnoughts, and supporting ships, 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. 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

During the Battle of Jutland on 31 May, Beatty's battlecruisers managed to bait Scheer and Hipper into a pursuit as they fell back upon the main body of the Grand Fleet. After Jellicoe deployed his ships into line of battle, Vanguard was the eighteenth ship from the head of the battle line after deployment.Corbett, frontispiece map and p. 428 Shortly after deploying from column into line ahead, her crew recorded that shells from the High Seas Fleet were falling nearby. During the first stage of the general engagement, the ship fired 42 rounds from her main guns at the crippled light cruiser beginning at 18:32,The times used in this section are in UT, which is one hour behind CET, which is often used in German works. claiming several hits. Between 19:20 and 19:30, Vanguard engaged several German destroyer flotillas with her main armament without result. This was the last time that the ship fired her guns during the battle, as the poor visibility hindered Jellicoe's ability to close with the Germans before Scheer was able to disengage under the cover of darkness. Vanguard fired a total of 65 high-explosive and 15 common-pointed, capped, twelve-inch shells and 10 shells from her four-inch guns during the battle.Campbell, pp. 152, 157, 212, 349, 358
