His service in this conflict involved carrying the members of the Carlisle Peace Commission to America, and playing a minor role in operations off the coast, before returning to European waters. He was present at the relief of Gibraltar and the Battle of Cape St Vincent with Admiral Sir George Rodney, and saw action at the Battle of Ushant with Admiral Richard Kempenfelt. Promoted to flag rank after the end of the war he served as governor of Newfoundland during the peace, but was unable to take any commands during the French Revolutionary Wars owing to his infirmity, and died in 1808 with the rank of admiral.
