A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term sloop-of-war encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions.
The capture of HMS Frolic was a naval action fought in the Atlantic on 18 October 1812, between the sloop-of-war USS Wasp, commanded by Master Commandant Jacob Jones, and the Cruizer-class brig-sloopHM Brig Frolic, under Commander Thomas Whinyates. The Americans captured the British vessel, but both vessels shortly thereafter were captured by a British ship of the line which happened upon the scene of the battle.
The capture of HMS Epervier was a naval action fought off the coast of Florida near Cape Canaveral on 28 April 1814, between the United States ship-rigged sloop-of-war USS Peacock, commanded by Master Commandant Lewis Warrington, and the British Cruizer-class brig-sloop Epervier under Commander Richard Wales. The Americans captured the British vessel after a one-sided cannonade, but the British merchant convoy escaped.
The capture of HMS Penguin was a single-ship action which took place on March 23, 1815 as part of the War of 1812. It occurred when United States Navy brig USS Hornet under the command of James Biddle encountered the British Royal Navy brig-sloop HMS Penguin off Tristan da Cunha, and was one of several naval engagements which occurred after the conflict ended due to the signing of the Treaty of Ghent in 1815. The gunnery of Hornet proved to be far more effective than Penguin, despite the two vessels being virtually identical in strength.
The Cherokee class was a class of brig-sloops of the Royal Navy, mounting ten guns. Brig-sloops were sloops-of-war with two masts rather than the three masts of ship sloops. Orders for 115 vessels were placed, including five which were cancelled and six for which the orders were replaced by ones for equivalent steam-powered paddle vessels.
Eleven ships of the Royal Navy have borne the name HMS Weazel or HMS Weazle, archaic spellings of weasel, while another was planned:
HMS Frolic was an 18-gun Cruizer-class brig-sloop of the Royal Navy. She was built by Boole, of Bridport and was launched on 9 February 1806. Although she took part in the capture of Martinique, Guadaloupe, and Saint Martin, she appears to have had an uneventful career until 8 October 1812, when the American sloop-of-war USS Wasp captured her after a fierce fight. Later that day the British recaptured Frolic and captured Wasp. Frolic was broken up in 1813.
Ten ships of the Royal Navy have borne the name HMS Confiance:
HMS Epervier was an 18-gun Cruizer-class brig-sloop of the Royal Navy, built by Ross at Rochester, England, and launched on 2 December 1812. USS Peacock captured her in 1814 and took her into service. USS Epervier disappeared in 1815 while carrying dispatches reporting the signing of a treaty with the Dey of Algiers.
The sinking of HMS Reindeer was one of the hardest-fought naval actions in the Anglo-American War of 1812. It took place on 28 June 1814. The ship-rigged sloop of war USS Wasp forced the Cruizer-class brig-sloop HMS Reindeer to surrender after far more than half the brig's crew, including the Captain, were killed or wounded. Reindeer was too badly damaged in the action to be salvaged so the Americans set her on fire.
HMS Landrail was a Cuckoo-class schooner built by Thomas Sutton at Ringmore, Teignmouth. Like all her class she carried four 12-pounder carronades and had a crew of 20. She had a relatively uneventful career during the Napoleonic Wars and the War of 1812 until 1814 when she was taken in a notable action, and then retaken. She was sold in approximately 1818.
HMS Leveret was a Cruizer-class brig-sloop built at Dover, England, and launched in 1806. She was wrecked in 1807.
HMS Magnet was a Cruizer-class brig-sloop built at Robert Guillaume’s yard at Northam and launched in 1807. She served in the Baltic, where she took two prizes, one an armed privateer, before wrecking in 1809.
HMS Whiting was a Royal Navy Ballahoo-class schooner of four 12-pounder carronades and a crew of 20. The prime contractor for the vessel was Goodrich & Co., in Bermuda, and she was launched in 1805. She was a participant at the Battle of Basque Roads. A French privateer captured her at the beginning of the War of 1812, shortly after the Americans had captured and released her in the first naval incident of the war.
The Sinking of HMS Avon was a single ship action fought during the War of 1812, and took place on 1 September 1814. In the battle, the ship-rigged sloop of war USS Wasp forced the Cruizer-class brig-sloop HMS Avon to surrender. The Americans could not take possession of the prize as other British brig-sloops appeared and prepared to engage. Avon sank shortly after the battle.
HMS Cruizer was a Royal Navy Cruizer-class brig-sloop built by Stephen Teague of Ipswich and launched in 1797. She was the first ship of the class, but there was a gap of 5 years between her launch and the ordering of the next batch in October 1803; by 1815 a total of 105 other vessels had been ordered to her design. She had an eventful wartime career, mostly in the North Sea, English Channel and the Baltic, and captured some 15 privateers and warships, and many merchant vessels. She also participated in several actions. She was laid up in 1813 and the Commissioners of the Navy sold her for breaking in 1819.
The Snake-class ship-sloops were a class of four Royal Navy sloops-of-war built in the late 18th and early 19th centuries. Though ships of the class were designed with the hull of a brig, their defining feature of a ship-rig changed their classification to that of a ship-sloop rather than that of a brig-sloop.
HMS Rinaldo was a Cherokee-class brig-sloop of the Royal Navy that was launched in July 1808. She was 236 66⁄94(bm), armed with eight 18-pounder carronades and two 6-pound bow chasers, and carried a crew of 75.
