HMS Clio was a Cruizer-class brig-sloop of the Royal Navy, launched at James Betts' shipyard in Mistleythorn in Essex on 10 January 1807.

In February 1807 Commander Thomas Folliott Baugh commissioned her and sailed her to the Leith Station on the North Sea.

[2] Then on 21 September 1808, while she was cruising off Fleckoro, Clio captured a small Danish privateer armed with six guns and carrying a crew of eleven men.

[5] On 30 March 1808, during the Gunboat War, Clio entered Tórshavn, the capital of the Faroe Islands, and briefly captured the fort at Skansin.

Shortly after, on 6 May, a German privateer who had assumed the name "Baron von Hompesch" plundered the defenceless city and seized the property of the Danish Crown Monopoly.

[6] Later, after the Jørgen Jørgensen affair (see also HMS Talbot), Britain declared the Faroese, the Icelanders, and the settlers in Greenland as "stranger friends" who were to be left in peace.

[20] Unknown to the British, Danish Captain Hans Peter Holm had returned to Egersund (SW Norway) with Lolland and four other brigs.

[21][22] On 1 May 1811,[23] the British sent four boats from Clio, Belette, and Cherokee,[24] into the western end of the sound, expecting to capture some shipping or do other mischief.

Some of the Danes landed to set an ambush from the cliff tops, whilst the armed boats were hidden behind a skerry.

As the British rowed boldly in, they met unexpected fire from howitzers and muskets; they immediately withdrew, with the Danish boats in pursuit.

[29] About a week later, on 13 or 14 October 1812 in the Baltic, off Hermeren, boats from Clio and Hamdryad captured the French privateer lugger Pilotin, which was carrying four 12-pounder carronades and had a crew of 31 men.

Three Danish luggers, each mounting two guns, came out from Rødby to support Pilotin but retreated when the British boats advanced towards them.

Clio sent in to Leith a small Danish privateer cutter of three (or four) guns and 22 men that she had taken on 22 October off Hiteroe.

[1] From 1826 to early 1827 her captain was Commander Robert Aitchinson, and she performed anti-smuggling patrols in the North Sea.

Onslow arrived at Luis Vernet's settlement at Port Louis to request that the Argentine authorities replace the flag of the United Provinces of the River Plate with the British one and leave the islands.

Lieutenant-Colonel José María Pinedo, of the schooner Sarandi considered resisting, but as most of his crew were British, thought better of it and sailed on 5 January.

On 27 June she captured the slaver ship Felix Vincedor (or Feliz Vencedor);[39] prize money was paid on 31 August 1844.

On 12 May a boat under Lieutenant Cox, with 12 men captured a slaver in the Piumas Islands with 300 slaves aboard.

However, some seven boats with a dozen men apiece sortied and re-captured the slaver, burning it after having landed the slaves.

[40] A week later, while Cox was taking water at Campos, some of the slavers took him and his men prisoner after wounding four seamen.

Clio then participated in the expedition up the Yangtze River, to the end of hostilities and signing of the Treaty of Nanking on 29 August.
