HMS Seahorse was a 24-gun sixth-rate frigate of the Royal Navy, launched in 1748. She is perhaps most famous as the ship on which a young Horatio Nelson served as a midshipman. She also participated in four battles off the coast of India between 1781 and 1783. The Royal Navy sold her in 1784 and she then became the mercantile Ravensworth. She made one voyage for the British East India Company (EIC) between 1786 and 1788. In 1789, she was sold to the French East India Company which had her refitted and renamed her Citoyen. In 1793 the French Navy purchased her and used her as a frigate. She was last listed in 1801.
The Capture of Sint Eustatius took place in February 1781 during the Fourth Anglo-Dutch War when British army and naval forces under Lieutenant-General Sir John Vaughan and Admiral George Rodney seized the Dutch-owned Caribbean island of Sint Eustatius. The capture was controversial in Britain, as it was alleged that Vaughan and Rodney had used the opportunity to enrich themselves and had neglected more important military duties. The island was subsequently taken by Dutch-allied French forces in late 1781, ending the British occupation.
Royal Admiral was an East Indiaman, launched in 1777 on the River Thames. She made eight trips for the East India Company (EIC) before she was sold. She then continued to trade. She made two trips carrying convicts from England to Australia, one as an East Indiaman in 1791, and a second in 1800. On this second voyage as a convict transport she was present at a notable naval action.
The Dutch cutter Kemphaan, meaning "game cock", was launched in 1781 as a 12-gun advice boat, with a mission of carrying dispatches between the Netherlands and its colonies. The Dutch increased her length by almost a quarter in 1787, gave her six more guns, and made a brig-sloop out of her. The British captured her in 1799 when they captured Suriname. She then served briefly in the Royal Navy as HMS Camphaan before she was broken up in early 1802.
The Dutch corvette Scipio was launched in 1784. She convoyed Dutch East Indiamen between the Cape of Good Hope and Europe until HMS Psyche captured her at Samarang in 1807. The British Royal Navy initially referred to her as HMS Scipio, but then renamed her to HMS Samarang in 1808. She was not commissioned in the Royal Navy. She was instrumental in the capture of Amboyna and especially Pulo Ay, and participated in the invasion of Java (1811). She was sold at Bombay in 1814. She then entered mercantile service, sailing between Liverpool and India until 1827. She became an opium trader sailing between India and Canton, and was broken up near Hong Kong in August 1833.
Several vessels have been named Thames, for the River Thames:
Royal Charlotte was launched in 1789 as an East Indiaman for the British East India Company (EIC). She made two trips to China for the EIC and on the second of these, after the outbreak of war with France in 1793, assisted at the British capture of Pondicherry. Then, the Admiralty, desirous of quickly building up the Royal Navy, purchased a number of commercial vessels, including nine East Indiamen, to meet the need for small two-decker fourth rates to serve as convoy escorts. The Admiralty purchased Royal Charlotte in 1795 and renamed her HMS Malabar. She made a trip to the West Indies where she was the lead ship of a small squadron that captured some Dutch colonies. She foundered in 1796 while escorting a convoy in the North Atlantic.
The Dutch sloop Sireene was launched in 1786. The British captured her in 1796 at the capitulation of Saldanha Bay. She then served in the Royal Navy, first briefly as the sixth rate HMS Daphne, and then from 1798 as the prison ship HMS Laurel. The Admiralty sold her in 1821.
Four vessels with the name Princess Royal have served the British East India Company (EIC).
Swallow was a teak-built packet ship that the British East India Company (EIC) launched at Bombay in 1779. She made nine trips between India and Britain for the EIC between 1782 and 1803. Her most notable exploit occurred on her seventh voyage, when she helped capture seven Dutch East Indiamen on 15 June 1795. The Royal Navy purchased her in 1804 and named her Lilly. She served in the navy until she was sold in 1811. During this time she participated in the capture of La Désirade island, and participated in a quixotic and unsuccessful attempt of General Francisco de Miranda to liberate the Province of Venezuela from Spain in 1806. Her whereabouts between 1811 and 1815 are obscure, but in 1815 J. Lyney, of London, purchased her and she sailed to the West Indies and to India as an EIC-licensed vessel until she wrecked on her way to Calcutta in 1823.
Houghton was launched in 1782 and made six voyages as an East Indiaman for the British East India Company (EIC). In 1794 she was part of an EIC squadron that had some success against French privateers and naval vessels in the Sunda Strait, and then in 1796 she participated as a transport in the British capture of St Lucia. She was sold in 1799 and her owner took her out to India to work in the tea trade between India and China. She foundered in 1803.
Earl Talbot was launched as an East Indiaman in 1778. She made six voyages for the British East India Company (EIC) between 1779 and 1793. She was sold for breaking up in 1793.
Busbridge was launched in 1782 as an East Indiaman for the British East India Company (EIC). She made seven voyages for the EIC before she was broken up. In June 1795, during her sixth voyage, she participated in the capture of eight vessels of the Dutch East India Company. She was laid up for several years on her return from her seventh voyage and sold for breaking up in 1805.
Lascelles was launched in 1779 as an East Indiaman. She made eight voyages for the British East India Company (EIC), and then briefly became a West Indiaman. She was sold to the government for use as a storeship, but was broken up in 1807.
Contractor was launched in 1779 as an East Indiaman. She made seven voyages for the British East India Company (EIC). She made one voyage as a transport for a military expedition before her owners sold her in 1800 for use as a transport.
Essex was launched in 1780 as an East Indiaman. She made six voyages for the British East India Company (EIC). On her first voyage she was present at an inconclusive battle with the French, and later at a second inconclusive engagement with a French frigate. In 1798 she was sold to be hulked or broken up.
Hinchinbrooke was the Spanish ship San Carlos that Admiral Rodney's squadron captured on 8 January 1780. She was sold as a prize and in 1781 commenced a voyage as an "extra" ship of the British East India Company. During the voyage a French squadron captured her at the Battle of Porto Praya, but the British Royal Navy recaptured her within a day or so. She was lost in the Hooghly River in 1783 on her return voyage to Britain.
Spy was built in France in 1780, almost surely under another name, and taken in prize. The British East India Company (EIC) purchased her in 1781 and used her for almost two years as a fast packet vessel and cruiser based in St Helena. It then sold her and she became a London-based slave ship, making two voyages in the triangular trade carrying enslaved people from West Africa to the West Indies. She then became a whaler, making seven whaling voyages between 1786 and 1795. She was probably wrecked in August 1795 on a voyage as a government transport.
The Dutch naval brig Meermin was built at Flushing; the Zeeland Admiralty purchased her in 1784. The British Royal Navy seized her in 1796. The Royal Navy named her HMS Miermen and registered but never commissioned her; it sold her in 1801.
