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 first USS Essex of the United States Navy was a 36-gun or 32-gun sailing frigate that participated in the Quasi-War with France, the First Barbary War, and in the War of 1812. The British captured her in 1814 and she then served as HMS Essex until sold at public auction on 6 June 1837.
HMS Leander was a 50-gun spar-decked frigate of the Royal Navy which saw service in the Napoleonic Wars, the War of 1812, and the Second Barbary War.
USS Nonsuch was a moderately successful privateer built in 1812 and then an armed schooner in the United States Navy during the War of 1812. She was sold for breaking up in 1826.
HMS Bulwark was a 74-gun third-rate ship of the line of the Royal Navy, launched on 23 April 1807 at Portsmouth. She was designed by Sir William Rule as one of the large class 74s, and was the only ship built to her draught. She was built at Portsmouth Dockyard by Nicholas Diddams.
HMS Niemen was a Royal Navy 38-gun fifth-rate frigate. She began her career as the Niémen, a 44-gun French Navy Armide-class frigate, designed by Pierre Rolland. She was only in French service for a few months when in 1809 she encountered some British frigates. The British captured her and she continued in British service as Niemen. In British service she cruised in the Atlantic and North American waters, taking numerous small American prizes, some privateers but mostly merchantmen. She was broken up in 1815, at the end of the Napoleonic Wars and the War of 1812.
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.
HMS Peruvian was an 18-gun Cruizer-class brig-sloop launched in 1808 at Parson's Yard, Warsash, England. She was the first naval vessel built at that yard. Peruvian captured two American privateers and participated in an expedition up the Penobscot River during the War of 1812. Then she claimed Ascension Island for Great Britain in 1815. She was broken up in 1830.
HMS Curlew (1812) was a Royal Navy Cruizer class brig-sloop built by (William) Good & Co., at Bridport and launched in 1812. She served with the Navy for only 10 years. During the War of 1812 she sailed from Halifax and captured several American privateers. Her greatest moment was her role in the 1819 British occupation of Ras Al Khaimah, leading to the signature of the General Maritime Treaty of 1820, which established the Trucial States, today the United Arab Emirates. Curlew was sold in 1822 in Bombay. She then had a 13 or so year career as an opium runner for James Matheson, one of the founders of the firm Jardine Matheson.
Two vessels served the British Royal Navy as His Majesty's Hired armed cutter Hero. Under the command of Lieutenant John Reynolds, the second hired armed cutter Hero captured some 30 merchantmen during the Gunboat War before the Royal Navy returned her to her owners. She was so successful that the Norwegian merchants offered a considerable reward for Hero's capture.
When HMS Maidstone and HMS Spartan captured the American privateer Rapid in 1812, the Royal Navy took her into service as the 14-gun gun-brig HMS Nova Scotia. She was renamed HMS Ferret in 1813 and sold in 1820.
Junon was a 40-gun Minerve-class frigate of the French Navy.
HMS Pictou was the American letter of marque schooner Zebra that the Royal Navy captured in 1813. The Admiralty purchased her in 1814 and she served on the North America station during the War of 1812 before the navy sold her in 1818.
HMS Briton was a 38-gun fifth-rate frigate of the British Royal Navy's Leda class. She was ordered on 28 September 1808 and her keel laid down at Chatham Dockyard in February 1810. Navy veteran Sir Thomas Staines was appointed her first captain on 7 May 1812 but did not join the ship until 17 June 1813 owing to his being at sea aboard HMS Hamadryad. After a period of cruising in the Bay of Biscay, the vessel set sail for South America where during the course of several missions she unexpectedly encountered the last member of the crew that had seized HMS Bounty from its captain Lieutenant William Bligh during the 1789 mutiny aboard the ship. With the coming of the Pax Britannica in 1815, Briton undertook various voyages before she was broken up in 1860.
HMS Doterel, was an 18-gun Cruizer-class brig-sloop of the British Royal Navy. Launched on 6 October 1808, she saw action in the Napoleonic Wars and in the War of 1812. In February 1809 she took part in the Battle of Les Sables-d'Olonne, then in April the Battle of Basque Roads. She was laid up in 1827 at Bermuda, but not broken up until 1855.
Hussar was an American privateer active during the War of 1812. Hussar was launched in 1812 and made several cruises, first two as a letter of marque, and two as a privateer, but apparently without success. HMS Saturn captured her.
HMS Barrosa was a frigate launched in 1812 for the Royal Navy. During the War of 1812 she captured several prizes. After the war she spent a decade or so (1823–1833) on harbour duties. The navy sold Barrosa in 1841.
The Thames-class frigate was a 32-gun fifth-rate frigate class of eight ships of the Royal Navy based on the Richmond-class frigate designed by William Bately. The ships were ordered to the older design, which was of a smaller type of ship compared to more modern designs, so that they could be built quickly and cheaply in time to assist in defending against Napoleon's expected invasion of Britain. The class received several design changes to the Richmond class, being built of fir instead of oak, with these changes making the class generally slower and less weatherly than their predecessors, especially when in heavy weather conditions. The first two ships of the class, Pallas and Circe, were ordered on 16 March 1804 with two more ordered on 1 May and the final four on 12 July. The final ship of the class, Medea, was cancelled on 22 October before construction could begin but the other seven ships of the class were commissioned between 1804 and 1806.
HMS Jason was a 36-gun fifth-rate Penelope-class frigate, launched in 1800. She served the entirety of her career in the English Channel, mostly in the frigate squadron of Commodore Charles Cunningham. Serving off the coast of France, especially around Le Havre and Cherbourg, she captured several French privateers and recaptured a British merchant ship in a cutting out expedition. Having only been in commission for around fifteen months, Jason was wrecked off the coast of St Malo on 21 July 1801. Her crew were saved and later exchanged, and in August her wreck was burned to prevent the French from rescuing it.
The Narcissus-class frigate was a 32-gun, 18-pounder fifth-rate frigate class of five ships of the Royal Navy. Designed by Surveyor of the Navy Sir John Henslow, the class was created to make use of shipyards that could not construct larger frigates. They were similar in design to the preceding 32-gun frigate class, the Amphion class, but were slightly shorter. Two ships were initially constructed, with a later batch of three being ordered in response to an Admiralty request for the resumption of production of proven frigate designs. The final two ships of the class were cancelled when the shipyard they were being constructed at went bankrupt. Unlike her sister ships, the name ship of the class Narcissus was armed with experimental short 24 pounders rather than 18 pounders.
