HMS Liverpool was a Royal Navy frigate, reclassified as a fourth rate. She was built by Wigram, Wells and Green and launched at Woolwich on 21 February 1814. She was built of pitch-pine, which made for speedy construction at the expense of durability. Her major service was on the East Indies Station from where in 1819 she led the successful punitive campaign against the Al Qasimi, a belligerent naval power based in Ras Al Khaimah which the British considered to be piratical. She was sold in 1822 but continued to operate in the Persian Gulf for an indefinite period thereafter. Service Liverpool was commissioned under Captain Arthur Farquhar in May 1814. Her first commission was very brief, though. She escorted convoys to Newfoundland, Nova Scotia and Quebec. She then served at the Cape Station before returning to Deptford to be paid off on 3 April 1816. First, though, she captured the French schooner Circonstance on 21 October 1815. Circonstance was carrying 67 slaves. On 5 Match 1816, Liverpool was driven ashore and severely damaged at Dover, Kent, England. She was later refloated and taken in to The Downs. In 1817 she was laid up at Deptford. In 1818, Liverpool was re-commissioned under Captain Francis Augustus Collier. He sailed her to join the East Indies Station, sailing via Mauritius and Trincomalee. While at Port Louis she captured four slave vessels. In the middle of 1819 she captured Deux Amis (29 July), Constance (17 August) and Jenny (24 August). Bounty money was paid for the freed slaves.
