HM Dockyard Devonport


HMS Royal Oak
HMS Royal Oak, a Revenge Class Battleship was built at HM Dockyard, Devonport, laid down on 15 January 1914, launched on 17 November 1914 and commissioned on 1st May 1916 at a final cost of £2,468,269. She was the eighth vessel to bear the name Royal Oak, replacing a pre-dreadnought scrapped in 1914. She had a displacement of 29,150 tons standard, 33,500 tons full load. Length: 624 ft (190 m), Beam: 88.5 ft (27.0 m), Draught: 28.6 ft (8.7 m) Her propulsion was provided by Steam turbines, driving 4 shafts, fed by 24 boilers, giving 26,500 shp (20 MW) with a top speed of 21 knots (39 km/h) and a range of 5,000 nmi (9,000 km) at 12 knots (22 km/h). Her Ships Complement was 997,1,150 officers and ratings. Armament consisted of 8 × 15 in /42 guns (381 mm), 14 × BL 6-inch (152.4 mm) Mk XII guns, 2 × QF 3-inch (76.20 mm) 20 cwt anti-aircraft guns, 4 × 47 mm guns and 4 × 21 in (533 mm) torpedo tubes (submerged). Her Armour Belt was 13 in (330 mm) amidships; 4,6 in (102,152 mm) ends. Deck: up to 5 in (127 mm). Turrets: 13 in (330 mm) faces; 5 in (127 mm) sides; 5 in (127 mm) roof. Barbettes: up to 10 in (254 mm) and Citadel: 11 in (279 mm)
Upon completion Royal Oak was assigned to the Third Division of the Fourth Battle Squadron of the Grand Fleet and engaged the German High Seas Fleet in the Battle of Jutland. Under the command of Captain Crawford Maclachlan, Royal Oak left Scapa Flow on the evening of 30 May in the company of the battleships Superb, Canada and Admiral Jellicoe's flagship Iron Duke. The next day's indecisive battle saw Royal Oak fire a total of thirty-eight 15-inch and eighty-four 6-inch shells, claiming three hits on the battlecruiser SMS Derfflinger, putting one of its turrets out of action, and a hit on the cruiser SMS Wiesbaden. She avoided damage herself, despite being straddled by shellfire on one occasion. Following the battle, Royal Oak was reassigned to the First Battle Squadron.
On 5th November 1918 — the final week of the First World War — she was anchored off Burntisland in the Firth of Forth accompanied by the seaplane tender Campania and the light battlecruiser Glorious. A sudden Force 10 squall caused Campania to drag her anchor, collide with Royal Oak and then with Glorious. Both capital ships suffered only minor damage; Campania, however, was holed by her initial collision and sank five hours later without loss of life.
At the end of the First World War, Royal Oak escorted several vessels of the surrendering German High Seas Fleet from the Firth of Forth to their internment in Scapa Flow and was present at a ceremony in Pentland Firth to greet other ships as they followed. She was sunk at Scapa Flow in October 1939.

1st July 1914 HMS Ocean
HMS Ocean
HMS Ocean (1900 - 1915) was built at Devonport Dockyard, laid down on 15th February 1897, launched on 5th July 1898, Commissioned in February 1900 and Mined in March 1915.
One of the Canopus class of pre-dreadnought battleships designed by Sir William White for use in the Far East and entered service between 1899 and 1902.
The lead ship was HMS Albion, which was followed by Canopus, Glory, Goliath, Ocean and Vengeance.
The class had primary armament consisting of four 12 inch (305 mm) 35 calibre long guns and six 6-inch (152 mm) 40 calibre long guns.
The introduction of HMS Dreadnought in 1906 rendered the class, and all other pre-dreadnought battleships, obsolete only a few years after the last-of-class entered service in 1902. The class saw service across the globe: in home waters, on the China Station, in the Mediterranean Fleet, in the Atlantic, in Africa, at Archangel, and in the Mediterranean where HMS Goliath and HMS Ocean were sunk during the Dardanelles campaign. The four surviving ships were reduced to subsidiary duties late in World War I and were scrapped in the early 1920s.

HMS Canopus
HMS Glory
HMS Goliath
HMS Ocean
HMS Vengeance

General characteristics
The Canopus-class battleships were designed for use in the Far East to counter the expanding Japanese navy and were required to be able to pass through the Suez Canal. They were designed to be smaller, lighter and faster than their predecessors, the Majestic-class battleships, although at 421.5 ft (128.5 m) they were slightly longer.
Armour
The armoured belt, situated at the waterline of the vessel, was 6 inches (152 mm) thick.
To save weight the Canopus class carried less armour than the Majestics, but a change from Harvey armour in the Majestics to Krupp armour in the Canopus class meant that the protective capability of the armour was maintained. Part of their armour scheme included the use of a special 1 in (25 mm) armoured deck over the armour belt to defend against plunging fire by the howitzers that France had reportedly planned to install on its ships, although this report proved to be false.
Armament
Like the Majestics, the Canopus class ships had four 12-inch (305 mm) guns mounted in twin turrets fore and aft. The final ship, Vengeance, had an improved mounting that allowed loading at any elevation; her turret gunhouses differed from those of her sisters in being Krupp-armoured and flat-sided (Krupp armour plates were difficult to form into curves). The ships mounted twelve 6-inch (152 mm) guns in armoured casemates as well having some smaller guns and four submerged 18-inch (450 mm) torpedo tubes.
Propulsion
The Canopuses were the first British battleships with water-tube boilers, which generated more power for their weight when compared with the cylindrical boilers used in previous ships. The new boilers led to the adoption of fore-and-aft funnels, rather than the side-by-side funnel arrangement used in many previous British battleships. The Canopus-class ships proved to be good steamers, consuming 10 short tons (9.1 t) of coal per hour at full speed. At 18 kn (33 km/h; 21 mph) they were fast for battleships of their time, a full 2 kn (2.3 mph) faster than the Majestics. The Canopuses were able to reach 4,500 mi (7,200 km) at 10 kn (19 km/h; 12 mph) with a full load of coal.
First World War Service
When the First World War broke out, Ocean was assigned to the 8th Battle Squadron, Channel Fleet, which she joined on 14 August 1914. She was detached to Queenstown, Ireland on 21 August to serve as guard ship there and to support a cruiser squadron operating in that area. In September 1914, she was ordered to relieve her sister ship Albion on the Cape Verde-Canary Islands Station, but while en route was diverted to the East Indies Station to support cruisers on convoy duty in the Middle East. She escorted an Indian troop convoy to Bahrain in October 1914. From October,December 1914, she served as flagship of the squadron in the Persian Gulf supporting operations against Basra.
In December 1914, Ocean was stationed at Suez, Egypt, to assist in the defence of the Suez Canal. She anchored in the mouth of the southern end of the canal on 29 December and remained in that area until mid-January 1915, when she proceeded northward up the canal. On 3,4 February, she supported ground troops against an Ottoman Turkish attack on the canal.
Dardanelles campaign
Ocean transferred to the Dardanelles in late February 1915 to participate in the Dardanelles campaign. On 1 March, she was one of the ships that bombarded the entrance forts and took hits from Turkish mobile artillery batteries, but suffered no serious damage. She supported the landings at Sedd el Bahr on 4 March.
On 18 March, Ocean took part in the attack on the Narrows forts. When battleship Irresistible was disabled by a mine in Erenkui Bay and all of her surviving crew was taken off by destroyers except for her commanding officer and some volunteers trying to save her, Ocean was sent in to tow her out. Ocean ran aground during the attempt, and, after freeing herself, found it impossible to take Irresistible under tow because of the shallow water, Irresistible's list, and heavy enemy fire. Ocean then took off the remaining members of Irresistible's crew and left the abandoned battleship to her fate; Irresistible sank unobserved by Allied forces, at around 1930.
Loss
While retiring with Irresistible's survivors aboard, Ocean herself struck a drifting mine at around 1900. Her starboard coal bunkers and passageways flooded, her steering jammed hard to port, and she listed 15° to starboard. She came under fire from shore and began taking hits, which flooded her starboard engine room and prevented steering repairs. The crippled Ocean was abandoned at around 1930 with little loss of life, destroyers taking off most of her crew. She then drifted into Morto Bay, still under fire, and sank there unobserved by Allied forces at about 22:30. When destroyer Jed entered the bay later that evening to sink Ocean and Irresistible with torpedoes so that they could not be captured by the Turks, the two battleships were nowhere to be found.

1st July 1914 HMS Queen
HMS Queen
HMS Queen, member of Formidable Class - Queen subclass of pre-dreadnought Battleships.
The Royal Navy's Formidable-class battleships were an eight-ship class of pre-dreadnoughts designed by Sir William White and built in the late 1890s. The class is often further divided into a separate London class, and the London class sometimes is divided further into a separate Queen class.
Queen subclass
The last two London class ships to be built, Prince of Wales and Queen, were identical to the other Londons except that they had open 12-pounder gun batteries mounted in the open on the upper deck amidships and had a lower displacement. Queen and Prince of Wales were laid down after the Duncan-class battleships that succeeded the Formidables and Londons, and were completed after the Duncans as well. They are generally considered part of the Formidable or London class, but the difference in the mounting of their 12-pounder guns, their lower displacement, and their later construction than the Duncans lead some authors to view them as constituting a Queen class separate from the Formidable and London classes.
The last of the ships to commission, Prince of Wales, was the last battleship for which Director of Naval Construction Sir William Henry White had sole design responsibility. She also was the last of the 29 battleships of the Majestic, Canopus, Formidable, London, Duncan, and Queen classes, commissioned between 1895 and 1904, which had all been based on the single, standard Majestic design and reached their final development in Queen and Prince of Wales.
Like all pre-dreadnoughts, the Formidables, Londons, and Queens were outclassed by the dreadnought battleships that began to appear in 1906. However, they continued in front-line duties through the early part of World War I.
HMS Queen was laid down at Devonport Dockyard on 12 March 1901. Lady Charles Scott (wife of Admiral Lord Charles Scott), Lady Ernestine Edgcumbe, Mrs. Jackson (wife of Rear-Admiral T. S. Jackson), and Mrs. Champness (wife of Chief Constructor of Devonport Dockyard H. B. Champness) took part in the ceremony. She was launched by Queen Alexandra on 8 March 1902. She was completed in March 1904.
Pre-World War I
HMS Queen was commissioned on 7 April 1904 at Devonport Dockyard for service with the Mediterranean Fleet. She returned to the United Kingdom and paid off in April 1906, then recommissioned on 8 May 1906 to return to the Mediterranean. She refitted at Malta in 1906,1907 for duty as a flagship, and on 20 March 1907 became Fleet Flagship, Vice Admiral. Her second commission for Mediterranean Fleet service ended when she paid off at Devonport on 14 December 1908. On 15 December 1908, Queen recommissioned for service with the Atlantic Fleet. She collided with the Greek merchant steamer SS Dafni at Dover on 1 February 1909, suffering no serious damage, and underwent a refit at Devonport in 1910,1911. On 15 May 1912, Queen transferred to the 3rd Battle Squadron, First Fleet. In April 1914 she became 2nd Flagship, Rear Admiral, in the 5th Battle Squadron, Second Fleet, and was assigned duties as a gunnery training ship at Portsmouth.
World War I
When World War I broke out in August 1914, the 5th Battle Squadron was based at Portland and assigned to the Channel Fleet. Queen returned to full commission and continued as second flagship of the squadron, which was engaged in patrolling the English Channel. She was attached temporarily to the Dover Patrol on 17 October 1914 for bombardment duties along the coast of Belgium in support of Allied troops fighting at the front, and on 3 November 1914 was detached to support the East Coast Patrol during the Gorleston Raid, then returned to the 5th Battle Squadron. The squadron transferred from Portland to Sheerness on 14 November 1914 to guard against a possible German invasion of the United Kingdom, but transferred back to Portland on 30 December 1914.
In March 1915, Queen transferred to the Dardanelles to participate in the Dardanelles Campaign, departing England on 13 March 1915 and arriving at Lemnos to join the British Dardanelles Squadron on 23 March 1915. She served as Flagship, Rear Admiral, 2nd Squadron, and supported the ANZAC landings at Gaba Tepe on 25 April 1915. Along with the battleships Implacable, London, and Prince of Wales, Queen transferred to the Adriatic Sea on 22 May 1915 to reinforce the Italian Navy against the Austro-Hungarian Navy when Italy declared war on Austria-Hungary. She arrived at her new base, Taranto, Italy, on 27 May 1915. From December 1916 to February 1917, Queen was refitted for service as a depot ship for the personnel of the Adriatic anti-submarine net barrage patrol in the Strait of Otranto. Most of her crew returned to the United Kingdom, leaving only a care-and-maintenance crew behind, and she was gradually disarmed as her guns were allocated to other duties. Most of her 6-inch (150 mm)) guns had been removed by April 1917, and all of her 12-inch (300 mm) guns had been put ashore by October 1917, where they were turned over to the Italian Army for use in repelling attacks by the Austro-Hungarian Army, although the turrets were left aboard. Queen became flagship of British Naval Forces, Taranto, serving as such until February 1918.
Post-World War I
Queen left Taranto and returned to the United Kingdom in April 1919 and was placed on the disposal list at Chatham Dockyard in May 1919. She won a temporary reprieve from the scrapper's torch in June 1919 when she was removed from the list and attached to the Pembroke Establishment to serve as an accommodation ship.
Disposal
Queen was placed on the sale list in March 1920 and sold for scrapping on 4 September 1920. She arrived at Birkenhead on 25 November 1920 to be lightened so that she could reach her scrapping berth at Preston, then arrived at Preston for scrapping on 5 August 1921.

1st July 1914 HMS Montagu
HMS Montagu - aground Lundy Island 1906
HMS Montagu was a Duncan-class pre-dreadnought battleship of the British Royal Navy. In May 1906 in thick fog, she was wrecked on Lundy Island, fortunately without loss of life. Although she would soon have been obsolescent if she had not been wrecked, this loss of one of its newest battleships was a blow to the Royal Navy, then in the early stages of the naval arms race with Germany.
HMS Montagu was laid down at Devonport Dockyard on 23 November 1899, and launched on 5 March 1901, when she was christened by Lady Charles Scott, wife of Lord Charles Scott, Commander-in-Chief, Plymouth. She began trials in February 1903.
HMS Montagu commissioned on 28 July 1903 at Devonport Dockyard for service in the Mediterranean Fleet. In February 1905, she transferred to the Channel Fleet.
Grounding
At 0200 hours on 30 May 1906 during radio communication trials carried out in thick fog, Montagu was steaming at high speed in the Bristol Channel when she ran into Shutter Rock on the southwest corner of Lundy Island. The force of impact was so great that her foremast was raked forward. The ship settled hard aground, with many holes in her hull, the worst of which was a 91-foot (28 m) long gash in her starboard side.[11]
A pilot cutter cruising in the vicinity of Lundy Island had encountered Montagu a short time earlier. The battleship had stopped engines, come abreast, and hailed from the bridge requesting a distance and bearing for Hartland Point on the mainland of England. Though the cutter supplied these accurately, the voice from the battleship's bridge replied that they must be wrong and that the pilot cutter must have lost her bearings. As Montagu restarted her engines and began to move ahead, the cutter shouted back that on her present course Montagu would be on Shutter Rock within ten minutes, and a short time later the sound of the battleship running aground carried through the fog.
The battleship's captain, believing Montagu was aground at Hartland Point, sent a party on a rowing boat to the north, instructing them to contact the Hartland Point Lighthouse. They instead got to the North light on Lundy Island, where officers asked the lighthouse keeper to inform the British Admiralty that they were aground south of Hartland Point. An argument ensued with the keeper over where they were until he pointed out he knew what lighthouse he kept.
The court martial convened for the affair blamed the thick fog and faulty navigation for the wreck,[14] and her commanding officer, Thomas B. S. Adair, and navigating officer, Lieutenant J. H. Dathan, were severely reprimanded and "dismissed the ship", Dathan losing two years' seniority.

1st July 1914 HMS Hibernia
HMS Hibernia
HMS Hibernia was laid down at Devonport Dockyard on 6 January 1904, launched on 17 June 1905, and completed in December 1906. She was the last of the eight King Edward VII-class battleships to be completed.
HMS Hibernia was a King Edward VII-class pre-dreadnought battleship of Britain's Royal Navy. Like all ships of the class (apart from HMS King Edward VII) she was named after an important part of the British Empire, namely Ireland. Commissioned in early 1907, she served as the flagship of the Rear Admirals of firstly the Atlantic Fleet and then the Channel Fleet. When the latter fleet was reorganised to the Home Fleet, she was based at the Nore.
In 1912, Hibernia hosted trials in naval aviation with the temporary addition of a runway to her foredeck, and the first launch of an aircraft from a vessel underway was achieved from her in early May. Later in 1912, after her experiment with aviation was completed, she and her sister ships formed the 3rd Battle Squadron. The squadron was assigned to the Grand Fleet at the beginning of World War I, and served on the Northern Patrol. In 1915 she supported the Dardanelles Campaign and provided cover for the evacuation from the Gallipoli Peninsula. On returning to the United Kingdom she was again attached to the Grand Fleet before being transferred to Nore Command in May 1916, finishing the war as an accommodation ship. She was decommissioned in 1919 and scrapped in 1922.
World War I
Upon the outbreak of World War I, the 3rd Battle Squadron was assigned to the Grand Fleet and based at Rosyth. It was used to supplement the Grand Fleet's cruisers on the Northern Patrol, and Hibernia continued her service as Second Flagship of the squadron. On 2 November 1914, the squadron was detached to reinforce the Channel Fleet and was rebased at Portland. It returned to the Grand Fleet on 13 November 1914.
Hibernia served in the Grand Fleet until November 1915.[7] During sweeps by the fleet, she and her sister ships often steamed at the heads of divisions of the far more valuable dreadnoughts, where they could protect the dreadnoughts by watching for mines or by being the first to strike them.
In November 1915, a division of the 3rd Battle Squadron consisting of Hibernia (which served as flagship of the division commander, Rear-Admiral Sydney Fremantle) and battleships Zealandia, Russell, and Albemarle was detached for service in the Dardanelles Campaign. The ships departed Scapa Flow on 6 November 1915; Albemarle suffered heavy damage in a storm on the first night of the voyage and had to return for repairs, assisted by Hibernia and accompanied by Zealandia. Hibernia, Zealandia, and Russell then pressed on and arrived at the Dardanelles on 14 December 1915. Hibernia served as stand-by battleship at Kephalo and covered the evacuation of V and W Beaches at Cape Helles on 8 January 1916 and 9 January 1916. Among those serving aboard her during this time was Augustus Agar, later V.C. and famous for exploits against the Bolsheviks and as captain of heavy cruiser Dorsetshire in World War II. Later in January, Hibernia was stationed at Milo in case she was needed to cover an evacuation of the French force at Salonika. Before the end of January, Russell relieved her as divisional flagship, and Hibernia returned to the United Kingdom, being reassigned to the Grand Fleet upon arrival at Devonport Dockyard on 5 February 1916. She underwent a refit there in February and March 1916 before rejoining the Grand Fleet.
On 29 April 1916, the 3rd Battle Squadron was rebased at Sheerness, and on 3 May 1916 it was separated from the Grand Fleet, being transferred to the Nore Command. Hibernia remained there with the squadron until October 1917.
In 1917 Hibernia's ten 6-inch (152-mm) guns were removed from their casemates because they were flooded in heavy seas and replaced with four 6-inch (152-mm) guns on the higher shelter deck.
Subsidiary duties
In October 1917, Hibernia left the 3rd Battle Squadron and paid off into the Nore Reserve at Chatham Dockyard, where she served as an overflow accommodation ship.
In September 1918, the Commander-in-Chief, Grand Fleet, Admiral David Beatty, called for a large target to be provided which would allow the battleships of the Grand Fleet, which had seen little action since the Battle of Jutland in 1916, realistic gunnery practice. To meet this requirement, it was suggested that Hibernia be converted to radio control and undergo other modifications so that she could assume duty as a target ship, but ultimately the predreadnought battleship HMS Agamemnon became available and was selected instead.
Disposal
In July 1919, Hibernia was placed on the disposal list at Chatham, and on 8 November 1921 she was sold for scrapping to Stanlee Shipbreaking Company of Dover. She was resold to Slough Trading Company in 1922, resold yet again to German scrappers, and towed to Germany for scrapping in November 1922.

Marlborough was ordered under the 1911 Naval Estimates and the contract to build her was awarded to Devonport Dockyard, of Plymouth. She was laid down on 25 January 1912 and launched on 24 October 1912. She was commissioned in June 1914, the second of the Iron Dukes to do so, behind her sister HMS Iron Duke. She cost in region of £2,043,437. The month after commissioning she joined the 1st Battle Squadron of the Grand Fleet, then based at Scapa Flow.
Service history
Along with the remainder of the 1st battle squadron, of which she was its flagship until February 1917, Marlborough saw action at the battle of Jutland. After firing 162 13.5 inch shells, she was hit by a torpedo that killed two and wounded two others. Marlborough had to be towed back to port with a slight list. After repairs were finished on 29 July 1916, she returned to the Grand Fleet.
In 1919, in the Russian Civil War, Marlborough was on duty in the Black Sea and, on orders of King George V, rescued his aunt, Dowager Empress Maria Feodorovna, and other members of the Russian Imperial Family, including Grand Duke Nicholas and Prince Felix Yusupov.

1st July 1914 HMS Implacable
HMS Implacable
HMS Implacable was a Formidable-class battleship of the British Royal Navy, the second ship of the name. Commissioned in September 1901, she was assigned to the Mediterranean Fleet and served with the fleet until 1908. After a refit, she transferred to the Channel Fleet, then onto the Atlantic Fleet in May 1909. By now rendered obsolete by the emergence of the dreadnought class ships, she was assigned to the 5th Battle Squadron and attached to the Home Fleet in 1912.
Upon the outbreak of World War I, Implacable, along with the squadron was assigned to the Channel Fleet. After operations with the Dover Patrol, she served in the Dardanelles Campaign, in support of the Allied landings at Gallipoli. Apart from a brief spell in England in March/April 1916 for a refit, she remained in the Mediterranean until June 1917, supporting firstly the Italian Navy and then the French Navy.
Returning to England, she was laid up until March 1918, and then served as a depot ship for the Northern Patrol. After the war, she was decommissioned and eventually sold for scrap in 1921.

26th Nov 1914 HMS Bulwark lost
HMS Bulwark
A powerful internal explosion ripped HMS Bulwark apart at 0750 on 26 November 1914 while she was moored at Number 17 buoy in Kethole Reach, 4 nmi (4.6 mi; 7.4 km) west of Sheerness in the estuary of the River Medway. Out of her complement of 750, no officers and only 14 sailors survived, two of whom subsequently died of their injuries in hospital. Most of the survivors were seriously injured.
The only men to survive the explosion comparatively unscathed were those who had been in Number 1 mess-deck amidships, who were blown out of an open hatch. One of these men, Able Seaman Stephen Marshall, described feeling the sensation of "a colossal draught", being drawn "irresistibly upwards", and, as he rose in the air, clearly seeing the ship's masts shaking violently.
Witnesses on the battleship Implacable, the next ship in line at the mooring, reported that "a huge pillar of black cloud belched upwards. From the depths of this writhing column flames appeared running down to sea level. The appearance of this dreadful phenomenon was followed by a thunderous roar. Then came a series of lesser detonations, and finally one vast explosion that shook the Implacable from mastheads to keel."
The destruction of Bulwark was also witnessed on board battleship Formidable, where "when the dust and wreckage had finally settled a limp object was seen hanging from the wireless aerials upon which it had fallen. With difficulty the object was retrieved and found to be an officer's uniform jacket with three gold bands on the sleeves and between them the purple cloth of an engineer officer. The garment's former owner had been blasted into fragments."
Perhaps the most detailed descriptions of the disaster came from witnesses on board battleships Prince of Wales and Agamemnon, both of whom stated that smoke issued from the stern of the ship prior to the explosion and that the first explosion appeared to take place in an after magazine.
On 29 November 1914 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 50 ft (15 m) east of the mooring. The starboard bow lay 30 ft (9.1 m) further away. The remainder of the ship had been torn apart so violently that no other large portions of the wreck could be found.
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 Vanguard, caused by a stokehold fire detonating a magazine, at Scapa Flow in 1917.
Inquiry into loss
A naval court of enquiry into the causes of the explosion held on 28 November 1914 established that it had been the practice to store ammunition for Bulwark's 6 in (150 mm) guns in cross-passageways connecting her total of 11 magazines. It suggested that, contrary to regulations, 275 six-inch shells had been placed close together, most touching each other, and some touching the walls of the magazine, on the morning of the explosion.
The most likely cause of the disaster appears to have been overheating of cordite charges stored alongside a boiler room bulkhead, and this was the explanation accepted by the court of enquiry. It has also been suggested that damage caused to one of the shells stored in the battleship's cross-passageways may have weakened the fusing mechanism and caused the shell to become 'live'. A blow to the shell, caused by it being dropped point down, could then have set off a chain reaction of explosions among the shells stored in Bulwark's cross-passageways sufficient to detonate the ship's magazines.
Memorials
A memorial to those lost on Bulwark and Princess Irene was erected at the Dockyard Church, Sheerness in 1921. It was dedicated by Archdeacon Ingles, the Chaplain of the Fleet. It was unveiled by 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, as part of the Naval Burial Ground.
