"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. By May 1808 command of the "Mutine" had passed to Commander Charles Montague Fabian. He sailed to Sierra Leone via Madeira and Gorée, to deliver the new governor of the colony, Thomas Perronet Thompson. "Mutine" then returned to Britain. Fabian sailed for Brazil on 8 November. "Mutine" was part of the squadron under Rear Admiral Michael de Courcy when wrecked near the island of Gorita in the Rio de Plata on 20 June 1809. Her carpenter joined those of "Agamemnon", , and in signing a document attesting that although "Agamemnon" might be righted, pumped out and somewhat repaired, she was effectively a total loss. "Mutine" remained on station, helping with the salvage operations, particularly of the cannons, 38 of which were rescued and landed at Gorita. "Mutine" was anchored in the harbour of Buenos Aires on 25 May 1810 during May Week when the revolution broke out in the city. Captain Fabian broke out bunting and saluted the revolution with salvos of cannon. He also gave a rousing speech on liberty and revolution, praising the revolutionaries for having gained their freedom. By 7 August "Mutine" was back in Britain, reporting to Lord Wellesley on the revolution in Argentina. On 22 October 1810, Commander Frederick William Burgoyne briefly took command before passing it on 31 October to Commander Nevison de Courcy. In 1812 de Courcy sailed "Mutine" to Quebec, and then home. 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. In 1813, "Mutine" was operating in the Western Approaches. Whilst "Mutine" was cruising in the Bay of Biscay De Courcy spotted a strange sail on the morning of 17 April. "Mutine" gave chase and at about 2pm her quarry hoisted the French flag. She then opened fire on "Mutine" with her stern chasers.
