"Shenandoah" reached Green Bay in the Bahamas on 13 December 1864 to investigate reports that Confederate privateers were being fitted out there to prey on Union commerce. Finding no trace of such activity, she hurried north to join the great Federal Fleet poised on the coast of North Carolina for the attack on Fort Fisher which protected Wilmington, North Carolina. On Christmas Eve, she closed to within 1,500 yards of the shore to bombard the works of Fort Fisher with all guns that could be brought to bear. In little more than an hour, the Confederate fort had been silenced, two of its magazines had been blown up, and the fort set afire in several places. The bombardment was kept up with good effect until after nightfall.
