HMS Lark was a 32-gun Richmond-class frigate fifth-rate frigate of the Royal Navy. She was launched in 1762 and destroyed in Narragansett Bay in 1778, during the American Revolutionary War.
USS Spitfire was a row galley authorized and constructed by Rhode Island during the American Revolution, and was placed in service in 1776. During this age of sail, row galleys were highly maneuverable compared to sailing ships whose movements were dependent on the wind. Spitfire had a reportedly successful career, helping to capture British cargo ships and engaging in the fight against British warships.
HMS Porpoise was a 12-gun sloop-of-war originally built in Bilbao, Spain, as the packet ship Infanta Amelia. On 6 August 1799 HMS Argo captured her off the coast of Portugal. Porpoise wrecked in 1803 on the North coast of what was then part of the Colony of New South Wales, now called Wreck Reefs, off the coast of Queensland, Australia.
HMS Montreal was a 32-gun Niger-class fifth-rate frigate of the Royal Navy. She was launched in 1761 and served in the Seven Years' War and the American War of Independence. The French captured her in 1779 and she then served with them under the name Montréal. An Anglo-Spanish force destroyed her during the occupation of Toulon early in the French Revolutionary Wars.
HMS Sibyl was a 28-gun Enterprise-class sixth-rate frigate of the Royal Navy. Sibyl was renamed HMS Garland in 1795.
HMS Orpheus was a 32–gun fifth rate frigate of the Royal Navy. She was launched in 1780, and served for more than a quarter of a century, before she was wrecked in 1807.
HMS Sprightly was a 10-gun cutter of the Royal Navy, built to a design by John Williams, and the name ship of her two-vessel class of cutters. She was launched in 1778. The French captured and scuttled her off the Andulasian coast in 1801.
HMS Kingfisher was the second ship in the 14-gun Swan class of ship sloops, to which design 25 vessels were built in the 1760s and 1770s. She was launched on 13 July 1770 at Chatham Dockyard, and completed there on 21 November 1770. She took part in the American Revolutionary War, enforcing the blockade of the Delaware Bay, and served in the Battle of Turtle Gut Inlet, near Cape May, New Jersey. While under the temporary command of Lieutenant Hugh Christian, she was burnt by her own crew to avoid capture on 7 August 1778 in Narragansett Bay during the Battle of Rhode Island.
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.
HMS Deux Amis was the French privateer schooner Deux Amis, launched in 1796. The British captured her in December 1796 and the Royal Navy took her into service under her existing name. She made one capture before wrecking in May 1799.
Pondicherry was a French East Indiaman, launched in December 1754, that the Royal Navy captured in 1756, early in the Seven Years' War with France. She was then sold and her new owners, who renamed her Pitt, proceeded to charter her to the British East India Company (EIC), for three voyages. During her first voyage she engaged a French warship, and then went on to chart a new route, Pitt's Passage, through the East Indies on the way to China. The EIC found this new route of the utmost importance as it was faster than their existing route, and was navigable in all seasons. After her return from her third voyage Pitt disappears from readily available online sources.
Two vessels of the Royal Navy have borne the name, HM galley Pigot. Both were acquired in 1778 during the American Revolutionary War, and both were lost that year; her crew destroyed the first to avoid her capture, and the Americans captured the second. Both were named for General Sir Robert Pigot, the general commanding the British Army at Newport, Rhode Island, during their service there.
HMS Weymouth was laid down as the East Indiaman Earl of Mansfield. The British Royal Navy purchased her on the stocks to use as a 56-gun fourth rate. She was launched in 1795 but never was commissioned in the Royal Navy. She was transferred in February 1796 to the Transportation Board as a transport. Lieutenant Robert Passmore took command in June 1796. Commander Charles Ryder succeeded Passmore in July 1798, and Commander Ambrose Crofton replaced Ryder in August 1799.
HMS Shamrock was a schooner built at Bermuda in 1808 of Bermuda cedar. She was built for the Royal Navy and was the name-ship of her class of 10-gun schooners. She was wrecked in 1811.
