CSS Tennessee

CSS Tennessee. The CSS *Tennessee* was a powerful ironclad warship constructed for the Confederate States Navy during the American Civil War. Serving as the flagship of Admiral Franklin Buchanan, it was the most formidable vessel in the defenses of Mobile Bay. Its brief but significant combat career culminated in a legendary, though ultimately doomed, stand against the entire Union Navy fleet at the Battle of Mobile Bay.

Construction and design

The vessel was built at Selma, Alabama, on the Alabama River, a major Confederate industrial center known for the Selma Naval Foundry. Its construction was overseen by naval constructor John L. Porter and chief engineer John W. Tyner. Due to severe shortages, the ship's railroad iron armor was sourced from the Montgomery and West Point Railroad. The design featured a distinctive sloped casemate with 6-inch thick iron plating, housing a powerful armament of six Brooke rifles, including two 7-inch and four 6.4-inch guns. Propelled by a weak, recycled steam engine from the river steamer *Alonzo Child*, its greatest flaw was its unreliable machinery, which significantly hampered its mobility in battle.

Service history

After its launch, the ironclad was towed downriver to Mobile for fitting out, where it was commissioned in February 1864 under the command of Captain James D. Johnston. For several months, it served as a floating battery, bolstering the defenses of Mobile Bay alongside three smaller gunboats known as the Mobile Squadron, and protected by the massive Fort Morgan and extensive torpedo fields. Its presence effectively blockaded the bay, preventing the Union's West Gulf Blockading Squadron, commanded by Admiral David G. Farragut, from accessing the vital port of Mobile. This stalemate persisted until Farragut amassed a decisive fleet to force the bay's entrance in August.

Battle of Mobile Bay

On the morning of August 5, 1864, Farragut's fleet, including four monitors led by the USS *Tecumseh*, began its famous assault. Initially, Admiral Franklin Buchanan held the *Tennessee* back under the guns of Fort Morgan. After the *Tecumseh* struck a mine and sank, Buchanan boldly ordered his ship to charge directly into the heart of the Union fleet. For over three hours, the ironclad engaged in a furious close-range duel with nearly every Union warship, including the flagship *Hartford*, the *Brooklyn*, and the monitors *Manhattan* and *Chickasaw*. Despite inflicting damage, its steering was disabled, smokestack shot away, and several gun ports jammed, leaving it immobilized and battered.

Capture and later use

With Admiral Franklin Buchanan wounded and the ship crippled, Captain James D. Johnston was forced to strike its colors, surrendering to the Union Navy. The captured vessel was taken into Union service as the USS *Tennessee*. After repairs at New Orleans, it was assigned to the West Gulf Blockading Squadron and participated in the Battle of Spanish Fort and the Battle of Fort Blakely during the Mobile Campaign in the spring of 1865. Following the end of the American Civil War, the ironclad was decommissioned and sold at New Orleans in November 1867.

Legacy

The CSS *Tennessee* is remembered as one of the strongest ironclads built by the Confederate States Navy. Its valiant but futile solo engagement at the Battle of Mobile Bay became a legendary episode of naval warfare, exemplifying Confederate ingenuity and desperate courage. The battle's outcome, immortalized by Farragut's alleged command, "Damn the torpedoes, full speed ahead!", effectively sealed the blockade of the Gulf Coast. The ship's capture marked a major victory for the Union Navy and was a significant blow to the Confederacy, hastening the fall of one of its last major ports.
