HMS Beaulieu was a 40-gun fifth-rate frigate of the Royal Navy. The ship was laid down in 1790 as a speculative build by the shipwright Henry Adams and purchased by the Royal Navy in June of the same year. Built to the dimensions of a merchant ship, Beaulieu did not have good sailing qualities. The frigate was commissioned in January 1793 by Lord Northesk and sent to serve on the Leeward Islands Station. She participated in the capture of Martinique in February 1794, and then was similarly present at the capture of the island of Saint Lucia in April. The frigate also took part in the initial stages of the invasion of Guadeloupe. Later in the year the ship's crew was beset by yellow fever and much depleted. Beaulieu was sent to serve on the North America Station to allow them to recuperate, returning to the Leeward Islands in 1795. In the following two years the ship found success in prizetaking and briefly took part in more operations at Saint Lucia. She returned to Britain at the end of 1796.

HMS Harpy was a Royal Navy Diligence-class brig-sloop, launched in 1796 and sold in 1817. She was the longest lived vessel of her class, and the most widely travelled. She served in both the battle of Copenhagen and the British invasion of Java, took part in several actions, one of which won for her crew a clasp to the Naval General Service Medal, and captured numerous privateers. The Navy sold her in 1817.
