After New Orleans fell to the Union fleet under Farragut on April 29, 1862, Mobile was the only serious problem for the blockade. It remained so, much like Wilmington, until late in the war. In August 1864, Farragut got permission from the Navy Department and troops from the War Department to seize the forts at the entrance to Mobile Bay. Following his famous "Damn the torpedoes" run past the forts, they fell and were occupied by Federal soldiers. Mobile itself remained in Confederate control, but it was no longer useful as a port.
