HMS Bulwark was one of five pre-dreadnought battleships built for the Royal Navy at the end of the 19th century. The Londons were a sub-class of the pre-dreadnoughts. Completed in 1902 she was initially assigned to the Mediterranean Fleet as its flagship. The ship then served with the Channel and Home Fleets from 1907 to 1910, usually as a flagship. From 1910 to 1914, she was in reserve in the Home Fleet.
Following the start of the First World War in August 1914, Bulwark, along with the rest of the squadron, was attached to the reformed Channel Fleet to protect the British Expeditionary Force as it moved across the English Channel to France. On 26 November 1914 she was destroyed by a large internal explosion with the loss of 741 men near Sheerness; only a dozen men survived the detonation. It was probably caused by the overheating of cordite charges that had been placed adjacent to a boiler-room bulkhead. Little of the ship survived to be salvaged and her remains were designated a controlled site under the Protection of Military Remains Act 1986. Diving on the wreck is generally forbidden.
Design and description
The five ships of the London class were ordered in 1898 in response to increased naval construction for the Imperial Russian Navy. The design for the London class was prepared in 1898; it was a virtual repeat of the preceding , though with significant revision to the forward armour protection scheme. Rather than a traditional transverse bulkhead for the forward end of the main belt armour, the belt was carried further forward and gradually tapered in thickness. Deck armour was also strengthened.Burt, pp. 206–209
Bulwark was long overall, with a beam of and a draught of at deep load. She displaced normally and up to fully loaded.Burt, p. 215 The ship had a metacentric height of . Her crew numbered 738 officers and ratings as a private ship and up to 789 when serving as a flagship. The London-class ships were powered by a pair of three-cylinder inverted vertical triple-expansion steam engines. The cylinders were , and diameter with a stroke of . Each set drove one screw, using steam provided by twenty Belleville boilers.Ball, pp. 354, 359 The boilers were trunked into two funnels located amidships. The London-class ships had a top speed of from . During her sea trials, Bulwark reached from .Ball, p. 354 The ships carried enough coal to give them a range of at a speed of .
The main battery of the London class consisted of four BL 12-inch (305 mm) Mk IX guns mounted in twin-gun turrets, one each fore and aft of the superstructure. Their secondary armament consisted of a dozen BL Mk VII guns mounted in casemates mounted in the sides of the hull. Defence against torpedo boats was provided by sixteen quick-firing (QF) 12-pounder () 12 cwt guns, eight of which were mounted in the central superstructure and the remaining eight guns were positioned on the main deck fore and aft and fired through unarmoured embrasures in the hull. Each of the two fighting tops were provided with three QF 3-pounder Hotchkiss guns. As was customary for battleships of the period, they were also equipped with four submerged 18-inch (450 mm) torpedo tubes in the hull, two on each broadside.
The Londons had an armoured belt that was thick; the transverse bulkheads on the aft end of the belt were thick. Their main-gun turret faces were protected by armour plates thick, atop 12-inch barbettes, and the casemate guns were protected with 6 inches of Krupp steel. The conning tower had thick sides. The ships were fitted with three armoured decks, ranging in thickness between each.
Construction and career Bulwark, named for "the solid part of a ship's side extending above deck",Silverstone, p. 219 was the fourth ship of her name to serve in the Royal Navy.Colledge & Warlow, p. 52 The ship was one of the three battleships ordered as part of the 1898–1899 Naval Estimates.Friedman, p. 274; Parkes, p. 408 She was laid down at HM Dockyard, Devonport, on 20 March 1899 and launched on 18 October 1899 by Lady Fairfax, wife of Admiral Sir Henry Fairfax, Commander-in-Chief, Plymouth.Ball, pp. 353, 356 The ship was completed in March 1902, at a cost of £997,846 plus £167,970 for her armament.Parkes, p. 408 Bulwark was commissioned by Captain Frederick Hamilton on 18 March for service with the Mediterranean Fleet. Admiral Sir Compton Domvile hoisted his flag on board on 1 May as Commander-in-Chief, Mediterranean Fleet.
1902–1909 She left Plymouth five days later, and arrived at Gibraltar on the 10th, then proceeded to Malta. In August, she was the flagship of a squadron visiting the Aegean Sea for combined manoeuvres and visits to Lemnos and Nauplia, and was slightly damaged during an exercise where the battleship misjudged the distance while attempting to tow Bulwark and collided with her. The following month, the annual manoeuvres with the Channel Fleet began off the coasts of Greece and Italy.Ball, p. 365 She visited Cagliari, Sardinia, in October during the exercise. In late December 1902 she was back in Greek waters when she visited Astakos in the Ionian Sea with HMS Irresistible and HMS Pioneer. On 18 April 1903, King Edward VII was hosted aboard Bulwark and he reviewed the fleet two days later. During the fleet manoeuvres in August off the coast of Portugal, the ship was visited by King Carlos I of Portugal. During Kaiser Wilhelm II's visit to Malta in April 1904, he assumed temporary command of Bulwark on 11 April as an honorary British Admiral of the Fleet. Domville and Bulwark sometimes served as observers during the manoeuvres with the Channel Fleet in May 1905, rather than participating in them. The Mediterranean Fleet was recalled to Malta from the Adriatic Sea on 27 October after the Dogger Bank Incident where the Russian Baltic Fleet mistakenly fired upon British fishermen as it passed through the North Sea en route to the Far East during the Russo-Japanese War. The fleet arrived on the 29th and began loading coal and ammunition in preparation for war, but stood down on 2 November after the Russians agreed to investigate the incident. On 10 December, Bulwark was ordered back to England for her crew to be paid off and Domville hauled his flag down three days later. The ship departed Malta on 14 December, arrived at Devonport on 21 December and was paid off two days later.Ball, pp. 367, 369
Bulwark was recommissioned on 3 January 1905 with Commander Edward Philpotts as the acting flag captain and departed on 5 January for Malta where she arrived on the 12th where Domville rehoisted his flag. On 9 June, the ship arrived at Genoa, Italy, where Domville hauled his flag down again and Captain Osmond Brock relieved Philpotts. Two days later, she arrived in Malta where Admiral Lord Charles Beresford hoisted his flag aboard as Commander-in-Chief of the Mediterranean Fleet. Bulwark began a lengthy refit at Malta on 30 October that lasted until 5 February 1906; the work included the addition of spotting tops equipped with Barr & Stroud coincidence rangefinders.Ball, pp. 354, 369; Friedman, p. 276 On 10 February, the ship departed for Lagos, Portugal, to rendezvous with the Channel and Atlantic Fleets for manoeuvres that lasted the rest of the month. The annual manoeuvres that began on 24 June were designed to evaluate the effectiveness of a strategy of commerce raiding as Bulwark was the flagship of the fleet blockading Lagos before the general fleet action began three days later.Ball, pp. 369–370 In 1906–1907, all the main-deck 12-pounders were repositioned on the superstructure.Burt, p. 219; Friedman, p. 276
On 19 January 1907, she departed Malta for Portsmouth to be paid off; after arriving on 26 January, Beresford hauled down his flag, although the ship was not paid off until 11 February at Devonport. On 12 February, Bulwark was recommissioned under the command of Captain Bertram Chambers to serve as the flagship of Rear-Admiral Frank Finnis of the Nore Division, Home Fleet. The ship visited Trondheim, Norway, on 18 June and then Invergordon, Scotland, on the 26th. She was present during the fleet review conducted by King Edward at Cowes on 3 August. After participating in the fleet manoeuvres earlier in October, Bulwark ran aground twice near Lemon Light in the North Sea while trying to avoid Dutch fishing ships on 26 October, but was able to get herself free both times. Her bottom was slightly damaged during the incidents and she entered drydock at HM Dockyard, Chatham on 31 October to begin repairs and a lengthy refit that lasted until 9 March 1908.Ball, pp. 370–371 While still in dockyard hands, Captain Arthur Leveson temporarily assumed command on 3 January and Rear-Admiral Stanley Colville relieved Finnis in command of the Nore Division on 17 January. After conducting torpedo and gunnery training and trials over the preceding months, Captain Robert Falcon Scott of Antarctic fame was appointed captain of Bulwark on 18 May. On 1 August, the ship put into Sheerness Dockyard to pay off the crew, some of whom joined the battleships and when she was formally decommissioned on 17 August. Bulwark was recommissioned the following day with a nucleus crew from the battleship .Ball, p. 371 She was transferred to the Channel Fleet on 3 OctoberBurt, p. 220 and arrived at Plymouth Sound on 11 December. Ten days later, Devonport Dockyard began repairs to the ship's 12-inch turrets and replacement of the worn-out gun barrels that took until 3 March 1909 to complete. That same day, Captain Bentinck Yelverton assumed command of the battleship.Ball, pp. 371–372 Under the fleet reorganisation of 24 March 1909, the Channel Fleet became the 2nd Division of the Home Fleet. Bulwark was present at the fleet review at Spithead conducted for the Lords of the Admiralty on 12 June.
1909–1914
She was refitted at Devonport from 25 August to 17 December and was paid off on 28 February 1910.Ball, p. 372 The following day Bulwark recommissioned into the reserve at Devonport with a nucleus crew as the flagship of Vice-Admiral George Neville, Vice-Admiral of the 3rd and 4th Divisions, Home Fleet, at the Nore, with Captain Cunningham Foot in temporary command. He was relieved by Captain George Hope on 18 March. Bulwark participated in the annual manoeuvres in July and she began a brief refit on 30 December that was completed on 25 February 1911. Captain Edmund Hyde Smith relieved Hope on 24 March and Vice-Admiral Prince Louis of Battenberg assumed command of the 3rd and 4th Divisions. Bulwark was paid off on 25 April, and Prince Louis hauled his flag down that same day. She was recommissioned as a private ship the next day with a nucleus crew. The ship was present during the Coronation Fleet Review of King George V at Spithead on 24 June. Bulwark arrived at Chatham on 23 July to unload her ammunition and stores in preparation for an extensive refit that began on 1 September and lasted until 1 May 1912.Ball, p. 374
