"Damn the Torpedoes!"
From the series: Mathew Brady Photographs of Civil War-Era Personalities and Scenes
A combined assault by a Federal fleet commanded by Rear Admiral David Farragut and Union infantry forces defeated a Confederate fleet and the 3 forts defending Mobile Bay, Alabama on August 5, 1864 (the forts would fall several days later following a short siege). The loss would deprive the Confederacy of one of its last major ports. (Farragut had captured New Orleans two years before.)
During the battle Farragut is widely reported to have ordered his ships forward despite the threat of submerged mines (then called torpedoes), calling out “Damn the Torpedoes, Go Ahead!" or more likely: "Damn the Torpedoes, Four Bells…”
