In 1814, Warren led the British forces which occupied Havre de Grace, Maryland and burnt much of the town, including the home of Commodore John Rodgers.

His daughter and heiress, Frances Maria Warren (1784–1837), married George Venables-Vernon, 4th Baron Vernon.

A popular figure in the area of his birth, there are a number of pubs named after him in Nottingham and nearby towns.
