HMS Captain (1869)

HMS ''Captain'' was a major warship built for the Royal Navy as a semi-private venture, following a dispute between the designer and the Admiralty. With wrought-iron armour, steam propulsion, and the main battery mounted in rotating armoured turrets, the ship was, at first appearance, quite innovative and formidable. However, poor design and design changes resulted in a vessel that was overweight and ultimately unstable. In terms of seaworthiness she was reported as closely comparable to the higher freeboard turret-ship HMS ''Monarch'', but her reduced freeboard added a sense of "sluggishness". The ''Captain'' capsized in heavy seas, only five months after being commissioned, with the loss of nearly 500 lives.

Background

The history of the ''Captain'' can be traced back to the Crimean War and the experiences of British captain Cowper Phipps Coles in 1855. Coles and a group of British sailors constructed a raft with guns protected by a "cupola" and used the raft, named the ''Lady Nancy'', to shell the Russian town of Taganrog on the Sea of Azov. The ''Lady Nancy'' "proved a great success",Preston 2002, p. 21. and Coles patented his rotating turret after the war. Following Coles' patenting, the British Admiralty ordered a prototype of Coles' design in 1859, which was installed in the floating battery vessel, HMS ''Trusty'', for trials in 1861.

The trials with the ''Trusty'' impressed the Admiralty, and it ordered a coastal defence vessel, HMS ''Prince Albert'', to be built with four of Coles' turrets and a wooden 121-gun first rate ship-of-the-line under construction, HMS ''Royal Sovereign'', to be converted to a turret ship. The ''Prince Albert'' was completed with four turrets mounting single 12-ton 9-inch guns and armour plate on the hull. The ''Royal Sovereign'' had five 10.5-inch, 12.5-ton guns in one twin and three single turrets.Brown 2003, pp. 42–44.

Both ships were flush deck with only a jury rig, and could only operate as coastal service vessels. The Admiralty, although impressed with Coles' rotating turret, required oceangoing vessels to protect its worldwide empire. Unfortunately for Coles, engine technology had not yet caught up with his designs and consequently oceangoing ships required sails. Combining rigging, masts, and turrets proved complicated if rigging was not to impede the turrets' arcs of fire.

In early 1863 the Admiralty gave Coles permission to work with Nathaniel Barnaby, head of staff of the Department of Naval Construction, on the design of a rigged vessel with two turrets and three tripod masts. In June 1863 the Admiralty suspended progress on the vessel until the ''Royal Sovereign'' finished her trials.

In 1864, Coles was allowed to start a second project: a rigged vessel with only one turret and based on the design of HMS ''Pallas''. He was lent the services of Joseph Scullard, Chief Draughtsman of Portsmouth Dockyard.Brown 2003, p. 44.

The next year, 1865, a committee established by the Admiralty to study the new design concluded that while the turret should be adopted, Coles' one-turret warship design had inadequate fire arcs.Preston 2002, p. 22. The committee proposed a two-turret fully rigged vessel with either two 9-inch ''(12 ton)'' guns per turret, or one 12-inch ''(22 ton)'' gun per turret. The committee's proposal was accepted by the Admiralty, and construction was started on ''Monarch''. ''Monarch's'' two turrets were each equipped with two 12-inch ''(25-ton)'' guns.

Stunned by the committee's decision to cancel his single-turret ship and his proposal for a two-turret vessel, and objecting to the ''Monarch's'' design, Coles launched a strong campaign against the project, attacking Vice Admiral Robert Spencer Robinson, Controller of the Navy, and various other members of the committee and the Admiralty. So vociferously did Coles complain that in January 1866 his contract as a consultant to the Admiralty was terminated. At the end of January, his protestations that he had been misunderstood led to his being re-employed from 1 March 1866.Brown 2003, p. 47. Further, Coles lobbied the press and Parliament, who were increasingly convinced that foreign powers—namely the United States—were pressing ahead with turret ships and thereby leaving Britain at a disadvantage at sea. On 17 April 1866, Coles submitted to the Admiralty his critique of the proposed ''Monarch'' (designed by the Controller's department and the Chief Constructor), stating that he could not publicly endorse a vessel which did not represent "my views of a sea going Turret-ship, nor can she give my principle a satisfactory and conclusive trial." Sensing that such an increasingly acrimonious and high-profile debate would only continue, the First Naval Lord, Admiral Sir Frederick Grey, minuted four days later (21 April) that Coles should at last be allowed to build what he felt would be a 'perfect' seagoing turret-ship.

Design and construction

On 8 May 1866, Coles informed the Admiralty of his selection of Laird Brothers' Cheshire yard, for the builder of the warship. The Cheshire yard had already built several successful iron warships. In mid-July, Lairds submitted two possible designs for Coles' proposed turret-ship.Preston 2002, p. 23. To prevent the rigging from being damaged when the guns fired through it, it was attached to a platform mounted above the gun turrets known as the hurricane deck instead of brought down to the main deck. Tripod masts were also used to minimise standing rigging.Chesneau and Kolesnik 1979, p. 21.

The design called for the ship to have a low freeboard, and Coles' figures estimated it at . Both the Controller and the Chief Constructor Edward James Reed raised serious concerns. Robinson noted that the low freeboard could cause flooding issues on the gun deck, and Reed criticised the design in 1866 both for being too heavy and for having too high a centre of gravity. On the latter, Reed noted that it would cause issues "especially as it is proposed to spread a large surface of canvas upon the ''Captain''". As the design neared completion, the First Lord of the Admiralty, Sir John Pakington, wrote on 23 July 1866 to Coles approving the building of the ship, but noting that responsibility for failure would lie on Coles' and the builders' lap.Brown 2003, pp. 47–48.

In November 1866, the contract for HMS ''Captain'' was approved, and the design was finished. She was laid down on 30 January 1867 at Laird's yard at Birkenhead, England, launched on 27 March 1869 and completed in March 1870.Preston 2002, p. 24.

Insufficient supervision during the building, owing partly to Coles' protracted illness, meant that she was heavier than planned.HMS ''Captain''
/ref> The designed freeboard was just , and the additional weight forced her to float deeper than expected, bringing the freeboard down to just . This compares with for the two-turret ''Monarch''.

The centre of gravity of the vessel also rose by about ten inches during construction. Reed raised havoc over the problems with the freeboard and the centre of gravity, but his objections were over-ruled during the ''Captain's'' trials.

She was commissioned on 30 April 1870 under Captain Hugh Talbot Burgoyne, VC. During trials in the following months, the ''Captain'' seemed to be everything that Coles had promised and won over many followers. In trials versus the ''Monarch'', she performed well and returned to sea in July and August, travelling to Vigo, Spain, and Gibraltar in separate runs.

Gunnery trials

A trial was undertaken in 1870 to compare the accuracy and rate of fire of turret-mounted heavy guns with those in a centre-battery ship. The target was a long, high rock off Vigo. The speed of the ships was ("some accounts say stationary"). Each ship fired for five minutes, with the guns starting "loaded and very carefully trained". The guns fired Palliser shells with battering charges at a range of about . Three out of the ''Captain's'' four hits were achieved with the first salvo; firing this salvo caused the ship to roll heavily (±20°); smoke from firing made aiming difficult. Note that the ''Captain'' could be expected to capsize if inclined 21°.An inclining test at Portsmouth conducted on 29 July 1870 suggested that the ''Captain's'' extreme heel with safety in smooth water was 15°-16°; calculations completed by 23 August 1870 showed that her danger angle was 21°, as had been predicted by Lairds in January or February 1870.

The ''Monarch'' and the ''Hercules'' also did better with their first salvo, were inconvenienced by the smoke of firing, and to a lesser extent were caused to roll by firing. On the ''Hercules'' the gunsights were on the guns, and this worked better than the turret roof gunsights used by the other ships.

Sinking

On the afternoon of 6 September 1870, ''Captain'' was cruising with the combined Mediterranean and Channel Squadrons comprising 11 ships off Cape Finisterre. The ship made 9.5 knots under sail in a force six wind, which was increasing through the day. The commander in chief, Admiral Sir Alexander Milne,
was on board to see her performance, and speed had risen to 11–13 knots before he departed. Not being accustomed to ships with such low freeboard, he was disturbed to note that at this speed with the strengthening sea, waves washed over the weather deck. The weather worsened with rain as the night progressed, and sail was reduced. The wind was blowing from the port bow so that sails had to be angled to the wind, speed was much reduced, and there was considerable force pushing the ship sideways. As the wind rose to a gale, sail was reduced to only the fore staysail and fore and main topsails.

Shortly after midnight when a new watch came on duty, the ship was heeling over 18 degrees and was felt to lurch to starboard twice. By then other ships in the combined squadron reported winds of Force 9 to 11 (on the Beaufort scale, 60 knots) with waves. Orders were given to drop the fore topsail and release sheets (ropes) holding both topsails angled into the wind. Before the captain's order could be carried out, the roll increased, and she capsized and sank with the loss of around 472 lives, including Coles'. The First Lord of the Admiralty, Hugh Childers, and Under-Secretary of State for War, Thomas Baring, both lost sons in the disaster. Only 18 of the crew survived, by making it to a boat which had broken free.

Court-martial

The subsequent investigation on the loss of ''Captain'', in the form of a court-martial,Brown 2003, p. 51. under Admiral Sir James Hope, took place on board HMS ''Duke of Wellington'', in Portsmouth Harbour. The court-martial expressed the opinion that "the ''Captain'' was built in deference to public opinion expressed in Parliament and through other channels, and in opposition to views and opinions of the Controller and his Department". This was a stunning (and unprecedented) rebuke of the mid-Victorian British public. For years they had demanded that Coles be allowed to produce a super-ironclad—armed with turrets—which could restore confidence in the primacy of the Royal Navy in a way which neither broadside ironclads like the partially armoured HMS ''Warrior'' nor Reed's central-battery versions seemed able to. Coles fatally added the requirement that a fully-rigged, seagoing turret-ship like HMS ''Monarch'' also be as low in the water as possible, like the low-freeboard (though mastless) American monitor USS ''Miantonomoh''; which had crossed the Atlantic under escort in June 1866, and which both Coles and the Board of Admiralty toured when she was anchored at Spithead.

The Admiralty later appointed a committee to consider ship designs past and present. It was somewhat of a departure for the Admiralty to seek scientific advice, but eminent engineers William Thomson (later Lord Kelvin) and William John Macquorn Rankine were appointed to the committee. It concluded that the ship was insufficiently stable: at 14 degrees heel (when the edge of the deck touched the sea) the righting moment due to the buoyancy pushing the ship upright again was just 410-foot-tons (1.2 MN·m). HMS ''Monarch'', the masted turret ship proposed by the 1865 committee and designed by Reed, and which was in the area at the time of the sinking, had a righting moment of 6,500-foot-tons (20 MN·m) at the same angle. Maximum righting moment occurred at a heel of 21 degrees, and thereafter declined to zero at 54.5 degrees. ''Monarch's'' righting moment increased to a maximum at 40 degrees. Survivors testified that the ''Captain'' floated upside down for between three and ten minutes, which proved that the ship had capsized. An inclining test had been carried out at Portsmouth on 29 July 1870 to allow the ship's stability characteristics to be calculated. ''Captain'' set sail on the ship's final voyage before the results of the trial were published.Brown 2003, p. 50.

Memorials

There are memorials to the crew in St Paul's Cathedral, Westminster Abbey, London, and St Anne's church in Portsmouth.

The conclusion of the 1870 Court Martial is engraved on the Memorial to HMS ''Captain'', in the north aisle of St Paul’s Cathedral:

:''Before the'' Captain ''was received from her contractors a grave departure from her original design had been committed whereby her draught of water was increased about two feet and her freeboard was diminished to a corresponding extent, and that her stability proved to be dangerously small, combined with an area of sail, under those circumstances, excessive. The Court deeply regret that if these facts were duly known and appreciated, they were not communicated to the officer in command of the ship, or that, if otherwise, the ship was allowed to be employed in the ordinary service of the Fleet before they had been ascertained by calculation and experience.''

Hunt for the wreck of HMS ''Captain''

In 2021 Dr. Howard Fuller, a Reader in War Studies at the University of Wolverhampton, initiated a Find the ''Captain'' project. This aims to raise funds in an effort to discover the wreck of the ''Captain'', whose sinking was the worst disaster suffered by the Royal Navy in the 'Pax Britannica' era. In company with a Galician-based documentary company, four wrecks were discovered by multibeam echosounder-scan off Cape Finisterre, Spain on 30 August 2022. The fourth wreck has a general configuration and dimensions closely corresponding with HMS ''Captain'''s. Fuller and Sir Sherard Cowper-Coles, Captain Cowper Coles great-grandson, suggested that the chances of finding the wreck were good and that fund raising had reached the half-way mark by June 2023.
