Belle Algerine operated in conjunction with the River Defense Fleet under Capt. J. A. Stevenson at Forts Jackson and St. Philip. Following action early in April 1862 she was represented as unfit for service having sustained bow damage while landing guns at Fort St. Philip, and handling the fire rafts with which the Confederates illuminated the channel below the forts against the passage of Farragut's fleet assembled there.
Comdr. Beverly Kennon in the Governor Moore reported that during the engagement at Forts Jackson and St. Philip Belle Algerine had twice run afoul of his ship and he eliminated the danger by ramming and sinking her on 24 April 1862.
