The Battle of Mobile Bay of August 5, 1864, was a naval and land engagement of the American Civil War in which a Union fleet commanded by Rear Admiral David G. Farragut, assisted by a contingent of soldiers, attacked a smaller Confederate fleet led by Admiral Franklin Buchanan and three forts that guarded the entrance to Mobile Bay: Morgan, Gaines and Powell. Farragut's perhaps apocryphal order of "Damn the torpedoes! Four bells. Captain Drayton, go ahead! Jouett, full speed!" became famous in paraphrase, as "Damn the torpedoes, full speed ahead!"
The battle was marked by Farragut's seemingly-rash but successful run through a minefield that had just claimed one of his ironclad monitors, enabling his fleet to get beyond the range of the shore-based guns.
