What was the Battle of Mobile Bay?
The Battle of Mobile Bay was a naval engagement during the American Civil War that took place on August 5, 1864. Union Admiral David Farragut was tasked with sealing off the port of Mobile, Alabama, from Confederate blockade runners.
Mobile Bay was heavily defended by two forts, rows of stakes, and many floating mines. As the Union fleet approached, the Confederate squadron opened fire. One Union ship, the Tecumseh, was struck by a mine and sunk. Despite this setback, Farragut urged his fleet forward with the famous command, "Damn the torpedoes! Full speed ahead". The Union fleet sailed into Mobile Bay and battled the Confederate fleet, eventually forcing the surrender of the Confederate admiral. The Union victory at Mobile Bay was a major blow to the Confederacy, as it closed one of their last major ports.

Battle of Mobile Bay, naval engagement of the American Civil War on August 5–23, 1864, during which Union Admiral David Farragut succeeded in sealing off the port of Mobile, Alabama, from Confederate blockade runners.
During the Civil War, Union ships imposed a blockade on Confederate ports. One of the few ports to defy the blockade was Mobile in Alabama, the most important Confederate port left on the Gulf of Mexico in 1864. In August of that year, Farragut was tasked with closing the port, completing the shipping stranglehold on the South, and using Mobile to supply Union forces moving south after the Battle of Atlanta.
The anchorage in Mobile Bay was well protected by two forts, Morgan and Gaines, and rows of stakes blocking the shallows, as well as many floating mines, then known as “torpedoes.” Farragut planned his attack well. In the early hours of August 5 his fleet of four monitors and fourteen wooden steamships crossed the bar at the entrance to the harbor on the incoming tide. The four monitors steamed on the starboard side of his wooden warships to protect them from Fort Morgan’s guns.
Ahead of them, a Confederate squadron consisting of three gunboats and the large ironclad CSS Tennessee lay in wait. As the Union fleet approached, the 46 heavy guns of Fort Morgan opened fire. The Union fleet responded, the exchange creating such smoke that Farragut had to climb the mainmast of his flagship USS Hartford to see what was happening. Ahead, the Confederate fleet joined in the battle. Maneuvering to engage the Tennessee, the Union ship Tecumseh struck a torpedo and sank, with few survivors among its crew of 114 seamen and officers. As the Union squadron came to an uncertain halt, Farragut urged them on with a command that, though the exact words are much contested, has passed into history as “Damn the torpedoes! Full speed ahead.”
Farragut’s careful plan threatened to unravel, but the attackers fought on. Narrowly avoiding collisions at the entrance, and with the Hartford in the lead, the Union fleet sailed on into Mobile Bay, where for three hours it battled the Tennessee while still being shelled from the two forts. After a long and hard fight, the Union ships finally succeeded in blowing a hole in the Tennessee’s iron armor. The wounded Confederate admiral, Franklin Buchanan, then ran up the white flag and surrendered.
Fort Gaines surrendered on August 8, and with no way to resupply it, on August 23 Fort Morgan surrendered as well, placing the waters of Mobile Bay firmly under Union control. The heavily defended city of Mobile itself was not taken until April 12, 1865, three days after the Confederate surrender at Appomattox.
Losses: Union, 1 ironclad of 18 ships, 151 men killed, 177 wounded; Confederate, 1 ironclad and 2 gunboats of 4 ships, 13 men killed, 22 wounded, and (by the time the forts had surrendered) 1,500 men captured.
