(August 1864), in U.S. history, triumph of Admiral David Farragut (Farragut, David) in sealing off the port of Mobile from Confederate blockade runners.

By 1864 Mobile Bay in Alabama was the most important Confederate port left on the Gulf of Mexico. It was protected by Fort Morgan, the ironclad Tennessee, and a string of mines (called torpedoes) in the narrow entrance passage to the bay.

Farragut's fleet sailed into Mobile Bay on the morning of Aug. 5, 1864. The Union ship Tecumseh hit a mine and sank. Farragut then climbed into the rigging of his flagship Hartford and cried out, “Damn the torpedoes: Full speed ahead!”

With the Hartford in the lead, the fleet sailed on into Mobile Bay, where for two hours it fought the Tennessee while coming under shelling from the guns at Fort Morgan. With the surrender of the Tennessee, Mobile Bay was in Union hands. On August 23 Fort Morgan surrendered, thereby sealing the Gulf coast from further blockade running.
