HMS Bulwark (1899)

HMS ''Bulwark'' was one of five pre-dreadnought battleships built for the Royal Navy at the end of the 19th century. The ''London''s 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.

''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. 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 ''London''s 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", was the fourth ship of her name to serve in the Royal Navy. The ship was one of the three battleships ordered as part of the 1898–1899 Naval Estimates. She was laid down at HM Dockyard, Devonport, on 20 March 1899 and launched on 18 October 1899 by Lady Harriet Fairfax, wife of Admiral Sir Henry Fairfax, Commander-in-Chief, Plymouth. The ship was completed in March 1902, at a cost of £997,846 plus £167,970 for her armament. ''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 visiting 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. She visited Cagliari, Sardinia, in October during the exercise. 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.

''Bulwark'' was recommissioned on 3 January 1905 with Commander Edward Philpotts as the acting fleet 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. 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. In 1906–1907, all the main-deck 12-pounders were repositioned on the superstructure.

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. 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 . 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. 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

By this time, a pair of the 3-pounders had been repositioned on the bridge and the others had been removed. While conducting sea trials, the ship grounded twice on Barrow Deep off the Nore during refit trials on 4 May 1912, extensively damaging her bottom. Repairs were not completed until the end of the month. On 4 June Captain Herbert Chatterton recommissioned ''Bulwark'' which was assigned to the 5th Battle Squadron (BS) of the Second Fleet. She briefly served as the flagship for the second-in-command of the squadron from 20 August until September, when his own ship returned. Aside from occasional gunnery practice, the ship was very inactive for the rest of the year; for example, she did not leave Spithead from 18 November 1912 to 25 February 1913. ''Bulwark'' was refitted at Portsmouth from 14 April – 4 June. The ship participated in the annual fleet manoeuvres in August and returned to Spithead on 30 October where she remained for the rest of the year. Captain Guy Sclater relieved Hyde Smith on 17 November.

''Bulwark'' was visited by King Christian X of Denmark when he inspected the squadron on 9 May 1914. On 22 May, she began her annual refit at Chatham which was completed on 9 July. The following day she was alerted to prepare for a test mobilisation in lieu of the annual fleet manoeuvres as part of the British response to the July Crisis. The mobilisation was ordered on 15 July, and the fleet was reviewed two days later at Spithead after which it conducted exercises.Ball, p. 378

First World War

At the beginning of the First World War, ''Bulwark'' and the 5th BS were based at Portland and assigned to the newly reformed Channel Fleet to defend the English Channel. After covering the safe transportation of the British Expeditionary Force to France in August, the 5th BS remained in Portsmouth until 4 September when they returned to Portland. They stayed there through October aside from exercises. From 5 to 9 November, ''Bulwark'' hosted the court martial of Rear-Admiral Sir Ernest Troubridge for his actions during the pursuit of the German battlecruiser and light cruiser in the Mediterranean Sea in August. On 14 November, the 5th BS was transferred to Sheerness because of concern that a German invasion of Great Britain was in the offing.

Explosion

A powerful internal explosion ripped ''Bulwark'' apart at about 07:53 on 26 November while she was moored at Number 17 buoy in Kethole Reach, west of Sheerness in the estuary of the River Medway. All the ship's officers were killed in the explosion and only a dozen ratings survived. A total of 741 men were lost, including members of the band of the gunnery school, HMS ''Excellent'', which was playing aboard. Only about 30 bodies were recovered after the explosion. In terms of loss of life, the incident remains the second most catastrophic accidental explosion in the history of the United Kingdom, exceeded only by the explosion of the dreadnought battleship , caused by a stokehold fire detonating a magazine, at Scapa Flow in 1917.

A naval court of enquiry into the causes of the explosion that was held on 28 November ruled out external explosions such as a torpedo or a mine because eyewitnesses spoke of a flash of flame near the aft turret and then one or two explosions quickly following, not the towering column of water associated with explosions against the outer hull. The gunnery logbook, recovered partially intact, and the testimony of the chief gunner's clerk, as well as several other survivors, said the six-inch ammunition magazines were being restowed to keep the cordite propellant charges together in lots that morning. This meant at least 30 exposed charges had been left in the cross-passages between the ship's magazines with the magazine doors left open when the ship's company was called to breakfast at 07:45. These passages were also used to stow hundreds of six-inch and twelve-pounder shells, and the court concluded that the cordite charges had been stowed against one of the boiler-room bulkheads which was increasing in temperature as the boilers were fired up. This ignited the cordite charges which detonated the nearby shells and spread to the aft twelve-inch magazine, which exploded.

Wreck site

On 29 November divers sent to find the wreck reported that the ship's port bow as far aft as the sick bay had been blown off by the explosion and lay east of the mooring. The starboard bow lay further away. The remainder of the ship had been torn apart so violently that no other large portions of the wreck could be found. One 12-inch gun was located on 28 December, a considerable distance away from her mooring, and later recovered.

The wreck is marked by the "East Bulwark" and "West Bulwark" buoys. It was designated as a controlled site in 2008 due to it being military remains and cannot be dived upon except with permission from the Ministry of Defence.

Memorials

A memorial to those lost on ''Bulwark'' and the minelayer (also lost in an accidental explosion) was erected at the Dockyard Church, Sheerness, in 1921. It was dedicated by Archdeacon Charles Ingles, the Chaplain of the Fleet, and unveiled by Admiral Hugh Evan-Thomas, Commander-in-Chief, The Nore. Victims of both ships are also commemorated on the Naval War Memorial at Southsea. Another memorial was placed in Woodlands Road Cemetery, Gillingham, Kent, as part of the Naval Burial Ground.
