On 4 September 1780 he was in command of Unicorn when he had the misfortune of encountering, in a fog off Tortuga, a French frigate and two ships of the line that captured him.

On 20 December 1782, during the Battle of the Delaware Capes Frederick, along with , captured the 40-gun American frigate South Carolina after a chase of eighteen hours on the Delaware River.
