HMS Mutine was a Royal Navy 18-gun Cruizer-class brig-sloop, built by Henry Tucker at Bideford and launched in 1806.

The British countered with a flotilla consisting of Mutine, Hebe and Cruizer, and four bomb vessels, Thunder, Vesuvius, Aetna and Zebra.

[4] On 22 August a Danish flotilla of three praams, each carrying 20 guns, and over 30 gunboats, attacked the inshore squadron off the entrance to Copenhagen's harbour.

The battle lasted for four hours, but resulted in little damage and few casualties, thought the Danes did drive back the British.

Mutine arrived on the scene in the evening, and after ascertaining the situation, Captain Stewart took over the prize vessel, by now identified as the Joannah, and put his own crew aboard her.

He sailed to Sierra Leone via Madeira and Gorée, to deliver the new governor of the colony, Thomas Perronet Thompson.

[2] When news of the outbreak of the War of 1812 reached Britain, the Royal Navy seized all American vessels then in British ports.

Mutine was among the Royal Navy vessels then lying at Spithead or Portsmouth and so entitled to share in the grant for the American ships Belleville, Janus, Aeos, Ganges and Leonidas seized there on 31 July 1812.

Whilst Mutine was cruising in the Bay of Biscay De Courcy spotted a strange sail on the morning of 17 April.

[17] Alexander's crew escaped, whilst Rattler pulled off the ship herself and salvaged it with the assistance of the schooner Bream.

[18][c] In 1847 the Admiralty awarded the Naval General Service Medal with clasp "Algiers" to still living claimants who had been present on 27 August 1816.

[2] Mutine spent most of her remaining years patrol between the south coast of England and Cork, Ireland.

The "Principal Officers and Commissioners of His Majesty's Navy" offered Mutine for sale at Plymouth on 3 February 1819.
