On 23 February 1799 Earl Fitzwilliam caught fire while she was in the Hoogly river. Nonsuch sent a boat, but she would not approach closer than 600 ft (183 m) to Earl Fitzwilliam because Earl Fitzwilliam's guns, which had been loaded were firing from the heat, and because of fear that the vessel itself would explode. A boat from Thetis came within an oar's length of Earl Fitzwilliam and hauled in as many crew members as it could. A midshipman from Thetis, with two sailors, rowed back and forth between the wreck and the larger boats that were standing off, and kept up his shuttle service until all the men still on board were rescued.
