When he bought her from the Admiralty through his secret agent on November 14, CommanderMatthew F. Maury had intended Rappahannock to replace the unwanted, iron CSS Georgia and was about to transfer Georgia's battery to her. She was ideal for a cruiser—wooden hull, bark-rigged, two engines and a lifting screw propeller—but she was doomed to serve the Confederacy no more glamorously than a floating depot.
She was commissioned a Confederate man-of-war underway, but while passing out of the Thames Estuary her bearings burned out and she had to be taken across to Calais for repairs. There LieutenantC. M. Fauntleroy, CSN, was placed in command.
Detained on various pretexts by the French Government, Rappahannock never got to sea and was turned over to the United States at the close of the war.
