The first – abortive—attempt was carried out between 24 and 26 December 1864 after a bizarre attempt to flatten some of the defenses by running what amounted to a fire-ship stocked with some 30 tons of gunpowder aground at a point some 250 to 300 yards north of the fort. Needless to say, that unique shore bombardment proved to be a huge flash in the pan causing little or no damage. When the fleet moved in on 24 December, Advance was in the 1st Reserve Division which appears to have constituted a second line of bombarding ships behind the ironclads. She fired only her large 20-pounder rifle and stopped that when she had to go to the assistance of the stricken and tow her to a safe anchorage.
