"Countess of Sutherland" arrived at Mauritius prior to 15 December 1803. Matthew Flinders was a prisoner at Mauritius when she arrived there. He estimated her value as a prize at £100,000. She was not on a list of vessels found at Port Napoleon at the time of its capture during the Invasion of Isle de France. However, by one report she had been hulked, and was broken up in 1821.
