HMS Tigress was the American merchantman Numa and then French letter of marque Pierre Cézar that the Royal Navy acquired by capture and put into service as the gunbrig Tigress. She spent some time on the West African coast in the suppression of the Triangular slave trade. The Admiralty later renamed her as Algerine. She was broken up in 1818.
HMS Pheasant was an 18-gun merlin class sloop of the Royal Navy.
HMS Vesta was an Adonis-class schooner of the Royal Navy during the Napoleonic War. She was built at Bermuda using Bermudan cedar and completed in 1806. She appears to have had an astonishingly uneventful decade-long career before the Admiralty sold her in 1816. She became a merchantman, sailing between the United Kingdom and Newfoundland until May 1823 when she sank after hitting an iceberg.
HMS Crocodile was a 22-gun sixth-rate post-ship launched in South Shields in 1806. She was broken up at Portsmouth in October 1816.
HMS Thais was built for the British Royal Navy in 1806 and was the name-vessel of her class of fire ships. Between 1811 and 1813 she served in the West Africa Squadron, which was attempting to suppress the slave trade. During this service she captured several slave traders and an American privateer. She made one voyage to the East Indies. Thais was sold in 1818. She then became a merchantman. She was last listed in 1826.
HMS Derwent was launched in 1807 and later that year became one of the first ships sent by the British Royal Navy to suppress the slave trade.
Kitty's Amelia was Jeune Amélie launched in France in 1802. A British letter of marque captured her in 1803 and she became a Liverpool-based slave ship in the triangular trade in enslaved people. Between 1804 and 1807 she made four voyages transporting enslaved people, but her chief claim to fame is that she performed the last legal slaving voyage for a British vessel. She was reported wrecked in 1809.
Dart was launched in South America under a different name. She was taken in prize circa 1806. Once under British ownership she performed one voyage as a whaler in the southern whale fishery. She then traded as a merchantman before in 1810 receiving a letter of marque. As a privateer she did something quite unusual: she made a voyage to Africa where she captured five slave ships. After this Dart returned to normal trading, this time with South America. In 1813 as she was returning to London from Buenos Aires she stopped at Pernambuco, where she was condemned as unseaworthy.
Several vessels have borne the name Kitty, a diminutive for the name "Catherine", and a name in its own right:
Rolla was a French brig launched in 1801 or 1803, that came into British hands in 1804. She became a privateer and then a slave ship in the triangular trade in enslaved people, but before she was able to embark any captives the French Navy captured her. The British Royal Navy recaptured her and took her into service as HMS Rolla. She served in Sir Home Riggs Popham's attack on Buenos Aires. She returned to Britain in December 1807 and was laid up. The Admiralty sold her in 1810 and she became a merchant vessel. She was last listed in 1826, and may have been lost on the coast of Brazil in 1825.
Barton was launched in Bermuda, probably in 1799, and built of Bermuda cedar. She first appeared in registers under the Barton name in 1801 as a slave ship in the triangular trade in enslaved people. The French captured her in 1803 before she had delivered the captives she had purchased for her second voyage. She returned to British ownership but her whereabouts between 1804 and 1810 are obscure. In 1811, she was again captured by a French privateer, which however gave her up. She grounded on 27 April 1819 at the entrance to the Sierra Leone River and was wrecked.
Barton was launched in 1794 as a West Indiaman, sailing primarily to Barbados. She was of average size for vessels launched at Liverpool at that time. She sailed under letters of marque and several times repelled attacks by French and Spanish privateers in single ship actions. The United States Navy captured and burnt her in 1814.
Elizabeth was launched at Bermuda in 1786 or 1790. She first appeared in Lloyd's Register (LR), in 1802. She then made four voyages as a slave ship in the triangular trade in enslaved people. During the second of these voyages a French privateer captured her. After the end of British participation in the trans-Atlantic trade in enslaved people, she spent a little over a year as a hired armed tender under contract to the British Royal Navy. She returned to mercantile service trading with Madeira or Africa, until another French privateer captured her in early 1810.
Minerva was launched in 1795 at Lancaster as a West Indiaman. In 1801 she was captured but immediately recaptured. Between 1802 and 1808 she made five voyages as a slave ship in the triangular trade in enslaved people. She was last listed in 1816.
Lion was launched in 1803 in Turkey, or 1802 in Spain. British owners acquired her in 1809, probably by purchase of a prize. She was a merchantman and letter of marque. She captured an American privateer in a notable single-ship action in 1813, some months before Lion was wrecked in 1813.
Roe was launched in France in 1792, almost certainly under another name. The British captured her and between 1801 and 1808 she became a Liverpool based slave ship, making four voyages in the triangular trade in enslaved people. After the end of the British slave trade Roe traded with Brazil. The Americans captured her in 1812 but she was quickly recaptured. She was wrecked in November 1814.
HMS Esk was a Cyrus-class ship-sloop launched at Ipswich in 1813. During the War of 1812 she captured one United States privateer, and fought an inconclusive action with another. Between 1825 and 1827 Esk was part of the West Africa Squadron, engaged in suppressing the trans-Atlantic slave trade, during which period she captured a number of slave ships. A prize she had taken also engaged in a notable single ship action. The Royal Navy sold Esk in 1829. Green, Wigram, and Green purchased her and between 1829 and 1845 she made four voyages in the British southern whale fishery as the whaler Matilda.
Commerce was a French vessel launched in 1798 and taken in prize in 1800. Initially she sailed as a West Indiaman. Then between 1801 and the end in 1807 of British participation in the triangular trade in enslaved people, Commerce made four voyages as a slave ship and also spent some time in 1803 cruising as a privateer. Afterwards, she continued to trade between Liverpool and West Africa. During one voyage in 1811 a French privateer captured her, but Commerce was recaptured. She was wrecked in November 1813 while returning to Liverpool from South America.
Ocean was a sloop launched in 1790 at Plymouth. Circa 1792 the Sierra Leone Company purchased her and sailed her in support of their colony. In 1793 the Company sent her on a voyage along the coast to trade for African commodities that she brought back to Freetown for re-export. The Company judged the experiment a success and the next year it sent several more vessels to do the same. The French captured Ocean in August 1796 and the Royal Navy recaptured her in January 1798. Her subsequent fate is obscure.
