On 5 August 1864, during the Battle of Mobile Bay, the Union monitor USS Tecumseh struck a Confederate torpedo (mine) and sank rapidly, killing most of its crew. Flag Officer David Farragut, aboard the wooden flagship USS Hartford, faced an immediate choice:
He chose to press forward, allegedly shouting, "Damn the torpedoes! Full speed ahead!" The fleet threaded the minefield, neutralized the forts, and captured the bay—closing the last major Confederate Gulf port.
The decision exemplified aggressive naval leadership and secured a strategic victory that aided Lincoln’s 1864 re‑election and the Union blockade’s completeness.
