This ship was highly active in various theatres of operations and had a prolific service life, the log of which is preserved and is accessible online through the University of Glasgow.[6] However, Cathcart's presence on board is, at present, only considered presumptive. He then in October 1802 took charge of the sloop Renard, another addition from the French Navy.[7] Having subsequently being appointed post captain, Cathcart took command of the frigate Clorinde, captured in 1803 at Santo Domingo.[3] He died in the West Indies of yellow fever while commanding her, on 4 June 1804 at the age of 21.[8] He is reported to have served with distinction at the raids on Boulogne, a naval action of August, 1801 in which the Royal Navy attempted to destroy components of the French fleet in that port.[8]
