HMS Centaur was a 74-gun third-rate ship of the line of the Royal Navy. Launched on 14 March 1797 at Woolwich Dockyard, she served as Sir Samuel Hood's flagship in the Leeward Islands and English Channel. During her 22-year career in the British navy, Centaur saw action in the Mediterranean, English Channel, West Indies and the Baltic, fighting against French, Dutch, Danish and Russian forces. She was decommissioned and broken up in 1819.

Service in the Mediterranean Captain John Markham commissioned Centaur in June 1797 and the next year sailed for the Mediterranean. In November she participated in the occupation of Menorca (historically called "Minorca" by the British).

On 13 November, Centaur, HMS Leviathan, and HMS Argo, together with some armed transports, relatively unsuccessfully chased a Spanish squadron. Argo did re-capture the British 16-gun Pylades-class sloop HMS Peterel, which the Spanish had taken the day before.

The next year, on 2 February 1798, Centaur pursued two Spanish xebecs and a settee, all privateers in royal Spanish service. She captured the privateer La Vierga del Rosario, which carried fourteen brass 12-pounder guns and had a crew of 90 men. The other two vessels escaped.

A year later, on 16 February 1799 Centaur, Argo and Leviathan attacked the town of Cambrils. Once the defenders had abandoned their battery, the boats went in. The British dismounted the guns, burnt five settees and brought out another five settees or tartans laden with wine and wheat. One tartan, the Velon Maria, was a letter of marque, armed with one brass and two iron 12-pounders and two 3-pounders. She had a crew of 14 men.

Then on 16 March 1799, she and Cormorant drove the Spanish frigate Guadaloupe aground near Cape Oropesa. Guadaloupe, of 40 guns, was wrecked.Norie (1842), p. 275.

In June, Centaur was involved in a brief action off Toulon before elements of Admiral Keith's fleet joined her. Centaur and fired at a brig-corvette and several settees off Toulon. They were then able to capture and destroy four of the settees.James (1837), Vol. 2, p. 262.

In the action of 18 June 1799, Markham's squadron captured a French squadron consisting of the 40-gun Junon, 36-gun Alceste, 32-gun Courageuse, 18-gun Salamine and 14-gun brig Alerte. The British took the captured vessels into service under their existing names, except that Junon became Princess Charlotte and Alerte became Minorca. Soon after, Centaur returned to England.

While working in the Channel in late 1800 and early 1801, on 25 January 1801 Centaur sent the Danish galiots Bernstorff and Rodercken into Plymouth. The Danish ships were carrying bale goods and nuts.Naval Chronicle, Vol. 5, p. 180.

Under Captain Littlehales, while serving with the Channel Fleet, Centaur and her sister ship, Mars, collided off the Black Rocks during the night of 10 March. Centaur lost her main and main-top-mast, which killed two men and injured four as they fell.Naval Chronicle, Vol. 5, p.371. Mars lost her head, bowsprit, foremast and main top-topmast and then almost grounded near the Île de Bas. In the last moment Canada was able to get a tow rope on her. Canada then towed Mars into Cawsand Bay.Naval Chronicle, Vol. 5, pp. 366 & 371. The subsequent court martial acquitted Marss captain and lieutenant of any negligence, but sentenced a lieutenant from Centaur to the loss of six months' seniority and dismissal from his ship.

Service in the West Indies

Late in 1802, Centaur sailed to the West Indies where she joined Vice Admiral Sir John Thomas Duckworth's squadron in Jamaica. When Commodore Sir Samuel Hood arrived to take command in the Leeward Islands, he raised his pennant in Centaur.

On 26 June 1803 Centaur participated in the capture of Saint Lucia and its citadel, Morne Fortunée; three days later the expedition took Tobago from the French.Southey (1827), Vol. 3, pp.230-1. The fleet went on to capture the Dutch islands.

On 21 August 1803, Centaur and captured the American ship Fame and her cargo of flour and corn. Then on 31 August Centaur detained the Dutch ship Good Hope, which was carrying wine and cordage.

On 20 September the British seized Demerara. The corvette Hippomenes, which was acting as a guard ship at Fort Stabroek, where she looked after the Governor's maritime affairs and served as harbour master for visiting ships,Southey (1827). Vol. 3, pp. 232-4. was the only vessel belonging to the Batavian Republic there and was included in the terms of capitulation. The British took her into service as .

In September Hood also received the assignment to blockade the bays of Fort Royal and Saint Pierre, Martinique. On 22 October Centaur captured the French privateer Vigilante. She was armed with two guns and had a crew of 37 men. The pursuit took seven hours.Naval Chronicle, 30 June 1804, Vol. 11, p. 156.

Centaur was sailing past Cap des Salinés, Martinique, early in the morning of 26 November when a battery fired at her. Hood had Maxwell anchor in Petite Anse d'Arlette. Then a landing party made up of Centaurs marines and about 40 sailors destroyed the battery. They also threw its six 24-pounders over the cliff. The militia guarding the battery had a brass 2-pounder gun but fled without putting up any resistance even though the landing party had to climb a steep, narrow path. Unfortunately, the premature explosion of the battery's magazine cost Centaur one man killed, and three officers and six men wounded, the only casualties from the operation. Then Centaur discovered another battery, this one armed with two 42-pounders and a 32-pounder, between the Grande and Petite Anse d'Arlette. The French abandoned the battery when a landing party approached. Once again, Centaurs men threw the guns over the cliff and destroyed a barracks and the ammunition stored there.Naval Chronicle, 30 June 1804, Vol. 11, p. 155.

Centaur was anchored in Fort Royal Bay, Martinique, when on the morning of 1 December she sighted a schooner towing a sloop. The pair were about six miles away and Hood believed that they were on their way to St. Pierre. He therefore instructed Maxwell to take Centaur in pursuit. Their prey did not initially notice them, but when they did, the schooner let go her tow and the vessels separated. After a pursuit that extended over 24 leagues, Centaur captured the schooner. She turned out to be the privateer Ma Sophie, out of Guadeloupe. She had a crew of 46 men and had had eight guns that she had thrown overboard during the chase in an attempt to increase her speed. When Ma Sophie and the sloop separated, Centaur sent the Sarah, an advice boat, after the sloop, which she captured.

Hood decided to use Sophie as a tender to Centaur. Lieutenant William Donnett became her captain with the task of monitoring the channel between Martinique and Diamond Rock, a basalt island south of Fort-de-France, the main port of Martinique, for enemy vessels. Subsequently, Donnett and Sophie frequently visited the Rock to gather both the thick, broad-leaved grass that the crew could weave into sailors' hats, and a spinach-like plant called callaloo. Callaloo, when boiled and served daily, kept the crews of Centaur and Sophie from scurvy and was a nice addition to a menu too long dominated by salt beef.Boswall (1833), p.210.

In late 1803 and early 1804, Centaur, under Captain Murray Maxwell, established several batteries on Diamond Rock. To ease its administration vis-à-vis the Admiralty, The British commissioned the rock as HMS Diamond Rock. Hood garrisoned it with two lieutenants and 120 men under the command of Lieutenant James Wilkes Maurice, his first lieutenant. Unfortunately, at some point during this period and for an unknown reason, Sophie blew up, killing all but one man of her crew.Boswall (1833), p.212. (Diamond Rock fell to an overwhelming French attack on 3 June 1805.)

On 3 February, Centaur sent her boats to cut out the French 18-gun brig-corvette Curieux from the Carénage, under the guns of Fort Edward at Fort-Royal harbour, Martinique. In the fight, the French lost 40 men killed and wounded, and the British had nine men wounded, including all three officers leading the cutting out party. The British took Curieux into the navy as HMS Curieux. Her original commander was Lieutenant Robert Carthew Reynolds, who had led the cutting-out party, but he died of the wounds he had received in the attack. His replacement as her commander was Lieutenant George Bettesworth of Centaur, also a member of the cutting-out party.Moore Holdsworth Macpherson, (1926), p.36.

On 25 April 1804, Centaur arrived off the Surinam River after a three-week voyage from Barbados. Her flotilla consisted of Pandour, Serapis and Alligator, all three en flute, Hippomenes, Drake, the 10-gun schooner Unique, and transports carrying 2000 troops under Brigadier-General Sir Charles Green. The British proposed surrender terms that the Dutch governor rejected. As an initial step in the campaign, Centaur sent her boats to capture the battery of Friderici. The landing party captured the battery at the cost of four men killed and three wounded. The Dutch surrendered on 5 May and Hood made Captain Conway Shipley of Hippomenes post-captain and appointed him to Centaur. (One day earlier the Admiralty had promoted Shipley into the ex-French 28-gun frigate Sagesse; he later assumed command of her at Jamaica.) Hood next appointed Captain Charles Richardson of the 28-gun frigate Alligator to command Centaur and the Admiralty confirmed his appointment on 27 September. The British captured two Dutch men-of-war, the 32-gun frigate Proserpine, which they took into service as , and the 18-gun corvette Pylades, which they took into service as . The British also captured the George, a schooner of 10 guns, and three merchant vessels.

On 30 July 1804, Centaur sent her boats into Basseterre Roads, Guadeloupe, where they cut out a schooner of unknown name and of two guns, as well as the privateer Elizabeth, which was pierced for 12 guns but mounting six. She had a crew of 65, most of whom were either killed, drowned, or swam ashore. The boats achieved these captures despite a complete lack of wind and under heavy grape and small arms fire from the batteries and troops that lined the beach. The boats had one man killed and five wounded, and brought out two wounded prisoners. Shipley described Elizabeth as "the fastest sailing Privateer out of Guadaloupe, and has been uncommonly fortunate this War."

Centaur also recaptured another , this one of Liverpool, that Decidé (actually Grande Decidé) had captured while Elizabeth was sailing from the coast of Africa with a cargo of slaves. Centaur detained, on suspicion, the "Grecian" ship St. Nicholas, which was carrying produce from Guadeloupe. Centaur also recaptured the schooner Betsey, which had been sailing in ballast. Then in December, Centaur recaptured the English ship Admiral Peckenham, which was carrying produce. Centaur sailed to England in the spring of 1805, before returning to the Leeward Islands.

A year later, on 29 July 1805, Centaur, under Captain Henry Whitby, in company with a squadron under Captain De Courcy, was sailing from Jamaica to join Nelson, when the squadron encountered a hurricane.Ellms (1841), pp.247-261. The storm threw Centaurs masts overboard, carried away her rudder and smashed and sent all her boats overboard.Marshall (1832), Vol. 3, Part 2, pp.229-31. Leaks that had started when Centaur had run ground some weeks before worsened substantially. The crew, especially the marines, labored at her pumps. For sixteen hours they were barely able to offset the water coming in. On the second day of the storm, a huge wave almost brought the first-rate crashing into Centaur.Mechanics' magazine, and journal of the Mechanics Institute, Vol. 7, p.112.
