HMS Doterel (1880)

HMS Doterel was a Doterel-class sloop sloop launched by the Royal Navy in 1880. She sank at anchor off Punta Arenas after an explosion on 26 April 1881, with the loss of 143 lives. Only twelve men survived. She was en route to join the Pacific Station. Her loss was initially the source of much speculation. Causes considered included an attack by the Fenians, a lost torpedo, and a coal gas explosion. An enquiry in September 1881 concluded coal gas was the cause.

In November 1881, an explosion in HMS Triumph (1870) killed three men and wounded seven; it was determined to have been caused by "xerotine siccative", one of a compound commonly called "patent driers." A survivor of the Doterel recalled smelling that compound shortly before the explosion. In 1883 the government determined xerotine siccative caused the first explosion on the Doterel, which set off the more damaging explosion of the forward magazine. The Admiralty ordered the compound withdrawn from use in the Royal Navy and better ventilation below decks.

Design and construction
The Doterel class was designed by Nathaniel Barnaby as a development of William Henry White's 1874 Osprey-class sloop. The graceful clipper bow of the Ospreys was replaced by a vertical stem and the engines were more powerful. The hull was of composite construction, with wooden planks over an iron frame. Power was provided by three cylindrical boilers, which supplied steam at 60 psi to a two-cylinder horizontal compound-expansion steam engine driving a single 13 ft screw. This arrangement produced 900 ihp and a top speed of 11 kn.

Ships of the class were armed with two 7-inch (90 cwt) muzzle-loading rifled guns on pivoting mounts, and four 64-pounder muzzle-loading rifled guns (two on pivoting mounts, and two broadside). Four machine guns and one light gun completed the weaponry. All the ships of the class were provided with a barque rig, that is, square-rigged foremast and mainmast, and fore-and-aft sails only on the mizzen mast.

Crew
Doterel would have had a normal complement of 140–150 men, although on the day of the explosion and sinking she had 155 men on board, despite five having deserted since leaving Sheerness. Some of the supernumeraries may have been bound for ships already on station in the Pacific; one of the survivors, Engineer Walker, was due to join HMS Garnet (1877).

Construction
Doterel was ordered from Chatham Dockyard and laid down on 13 May 1878. She was launched on 2 March 1880 from Number 3 slip, and was named by Miss Hunt-Grubbe, daughter of the captain of Steam Reserves at Chatham. She was commissioned on 7 December 1880.

Service
Sloops such as Doterel were used in the far-flung parts of Britain's maritime empire for constabulary duties. Barnaby, Doterel's designer, was an enthusiast of heavily armed but un-armoured frigates, sloops and corvettes, arguing that the Navy's tasks were best accomplished by a number of small, cheap ships. The system of colonial cruisers provided an inexpensive peace-keeping force for the protection of British interests, and gave imperial representatives a supply of sailors, marines and guns to deal with petty tyrants, minor insurrections and banditry. Doterel was assigned to the Pacific Station, which included the western coasts of North and South America as well as China and Japan. Under Commander Richard Evans she sailed from Sheerness, Kent on 17 January 1881. Having called at Madeira, St Vincent and Montevideo, she anchored at Punta Arenas, Chile on 26 April 1881 at 09:00.

Sinking
At about 10:15 on 26 April while the ship was at anchor off Punta Arenas, an explosion occurred in the forward magazine. Eyewitnesses described how objects of every type were thrown high into the air, and a huge column of smoke was seen to rise from the ship. The ship sank instantly.

Boats of every kind put off from shore to seek survivors, as well as from the missionary schooner Allen Gardiner, the Chilean schooner San Jose, and the pontoon Kate Kellogg. 143 of the 155 crew members were killed. The captain was one of the twelve survivors, rescued by a boat from San Jose. He was found stripped naked by the blast and bleeding from several wounds.

That afternoon, crews recovered bodies from the water; only three were recovered whole. The various body parts were put into boxes and buried at sea the same afternoon. Reverend Thomas Bridges, an Anglican missionary at Ushuaia, presided over the mass funeral in the harbor for the many sailors killed in the explosion.

Commander Evans, the captain of Doterel telegrammed the Admiralty from Montevideo on 3 May 1881:

"'Doterel' totally destroyed and sunk by explosion of fore magazine at Sandy Point, 10 a.m., April 26. Cause unknown, supposed boiler burst and exploded magazine. Twelve survivors, all well, proceeding in Britannia for Liverpool. Stokes (lieutenant) remains Sandy Point, awaiting orders. Have telegraphed Pacific, and Jones. Survivors. Commander Evans, Lieutenant Stokes, Paymaster Colborne, Engineer Walker (of Garnet), Carpenter Baird, Gunner's Mate Pengelly, Quartermaster Trout, Caulker's Mate Ford, Shipwright Walkers, Ordinary Seaman James Smith, Stoker Turner, Marine Summers. Discharged. Inlis (clerk), Miggeridge (sick bay man), Hayes (private), Motton (A.B.). John Ellery (A.B.) deserted. Dead.—Eight officers, 135 men."

- Commander Richard Evans, 3 May 1881

The ship's guns, screw and other valuable fittings were salvaged by HMS Garnet (1877) and HMS Turquoise (1876). The contemporary rules governing pensions allowed the widow or dependent children of the dead men a gratuity equal to a year's pay, although the loss of their property was not compensated.

Cause of the explosion
Initial reports blamed an explosion in the boilers, which detonated the magazine. This was definitively proven to be false when crew of the Garnet found the boilers in perfect condition. Conjecture also suggested the Fenians could have blown up the ship with a coal torpedo, the explosion could have been caused by a Whitehead torpedo lost by HMS Shah (1873) in 1878, or coal gas from the bunkers might have caused the explosion. An enquiry was held at Portsmouth, which referred the evidence to a scientific committee. In September 1881, they determined that the explosion was caused by the detonation of coal gas in the bunkers, and that no crew members were at fault.

On 21 November 1881, an explosion occurred in HMS Triumph (1870), caused by a drying compound called "xerotine siccative", also called a patent drier. Three men were killed and seven were wounded.

It was not until 1883 that the cause of the Doterel explosion was settled. A surviving crew member of that ship, upon later smelling xerotine siccative while on board HMS Indus (1839), stated that he had smelled it before the 1881 explosion. He explained to authorities that a jar of liquid had cracked while being moved below deck. Subsequent investigation revealed that just before the explosion in Doterel, two men were ordered to throw the jar overboard. While cleaning the leaking explosive liquid from beneath the forward magazine, the men may have broken the rule of not having an open flame below decks. The xerotine siccative exploded first, setting off the huge explosion in the forward magazine, which contained 4 tons and 7 cwt (4,456 kg) of explosives.

The Admiralty ordered xerotine siccative to be discontinued from use in the fleet, and a system of ventilation was recommended for all ships of the Royal Navy.
