Union Admiral David Farragut led a decisive naval victory against Confederate forces at Mobile Bay, Alabama, famously ordering 'Damn the torpedoes, full speed ahead!' The battle resulted in Union control of the last major Confederate port on the Gulf Coast.

The Battle of Mobile Bay stands as one of the most decisive naval engagements of the American Civil War where Admiral David Farragut secured a crucial Union victory on August 5, 1864. This historic battle demonstrated Farragut's exceptional leadership and tactical brilliance as he commanded the Union fleet against Confederate forces in Alabama's Mobile Bay.

During this legendary confrontation Farragut uttered his famous command "Damn the torpedoes full speed ahead!" as he led his fleet through a treacherous minefield. The battle's outcome proved pivotal in the Union's strategy to control Confederate ports and effectively cut off vital supply lines. His bold actions not only captured the last major Gulf Coast port under Confederate control but also cemented his place in American naval history.

Mobile Bay served as a crucial Confederate stronghold in 1864, functioning as the last major port on the Gulf Coast under Confederate control. The bay's deep-water harbor connected to the Alabama River system, creating a vital supply route for Confederate forces.

The port's strategic value centered on three key aspects:

• Trade Operations: Mobile Bay processed 40% of Confederate cotton exports to Europe in exchange for military supplies
• Naval Protection: Three fortified positions (Fort Morgan, Fort Gaines Fort Powell) guarded the bay's entrance
• Supply Distribution: The port linked to a railroad network that transported goods throughout the Confederate states

Confederate defenses at Mobile Bay included:

Defense Element	Quantity/Description
Heavy Guns	400 artillery pieces
Naval Mines	180 underwater devices
Iron-clad Vessels	3 operational ships
Infantry Forces	2,000 soldiers

The Union's capture of Mobile Bay would:

• Eliminate Confederate access to foreign supplies through Gulf Coast shipping lanes
• Disrupt internal supply routes between Confederate states
• Enable Union forces to launch inland operations from a secured port
• Prevent blockade runners from accessing the last major Confederate port

The bay's location 150 miles east of New Orleans made it a strategic target for completing the Union's Gulf Coast blockade strategy. Control of Mobile Bay proved essential for severing Confederate supply lines across the eastern theater of operations.

Admiral David Farragut developed a comprehensive battle strategy for the Mobile Bay assault in July 1864, focusing on coordinated naval and land operations to overcome Confederate defenses.

Farragut assembled a powerful fleet of 18 warships for the Mobile Bay operation. The fleet included 4 ironclad monitors (USS Tecumseh, Manhattan, Winnebago, Chickasaw) and 14 wooden ships. The wooden vessels were organized in pairs, with larger ships positioned on the port side to shield their smaller counterparts from Fort Morgan's artillery fire. The fleet carried a total of 199 guns with an additional 22 guns mounted on the monitors.

Equipment specifications for Union fleet:

Vessel Type	Number	Total Guns	Special Features
Ironclad Monitors	4	22	Armor plating, rotating turrets
Wooden Sloops	14	199	Steam-powered, paired formation

The Confederate defense system at Mobile Bay incorporated multiple fortified positions:

• Fort Morgan contained 46 heavy guns positioned at the main channel entrance
• Fort Gaines housed 30 artillery pieces guarding the western approach
• Fort Powell protected the shallow Mississippi Sound passage
• CSS Tennessee served as the primary ironclad defender with 6-inch armor plating
• Three gunboats (CSS Morgan, Gaines, Selma) supported defensive operations
• Torpedo field included 180 submerged explosive devices across the channel

The defenders positioned these elements strategically to create overlapping fields of fire. The Confederate command concentrated their strongest defenses at Fort Morgan, recognizing it as the most likely point of Union attack. They established a triple-layer defense system combining fixed fortifications, mobile naval forces with the ironclad Tennessee leading smaller gunboats.

Admiral David Farragut initiated the attack on Mobile Bay at 6:47 AM on August 5, 1864, leading his fleet of 18 warships in a daring assault against the Confederate defenses.

The USS Tecumseh struck a mine at 7:40 AM, sinking in less than two minutes with 93 crew members lost. Farragut's flagship USS Hartford faced a critical moment as ships ahead began backing up, creating confusion in the battle line. Standing in the rigging of the Hartford, Farragut assessed the situation and shouted his famous order, "Damn the torpedoes, full speed ahead!" The admiral's decisive action rallied the Union fleet to continue their advance through the minefield.

The Union fleet's breakthrough occurred between 8:00 AM and 9:00 AM as ships passed Fort Morgan's artillery barrage. Union vessels executed a precise tactical formation:

• Maintained paired positions with larger ships protecting wooden vessels
• Sustained a continuous broadside fire against Fort Morgan's batteries
• Directed chain-shot volleys at Confederate gunboat crews
• Deployed smoke screens from coal-fired engines to obscure Confederate targeting

Confederate casualties during the breakthrough included:

Defense Point	Union Impact
Fort Morgan	12 guns disabled
CSS Selma	Captured
CSS Gaines	Run aground
CSS Morgan	Retreated to Mobile

The Union fleet's successful passage through the defensive line placed them in control of the lower bay, cutting off Confederate naval forces from potential escape routes.

The Battle of Mobile Bay concluded with a decisive Union victory on August 23, 1864. Admiral Farragut's successful campaign resulted in complete Union control of Mobile Bay, effectively closing the last major Confederate port on the Gulf Coast.

After two weeks of intense bombardment from Union naval forces and siege operations on land, Fort Morgan surrendered on August 23, 1864. The fort's commander, General Richard Page, destroyed ammunition supplies prior to surrender, leading to his imprisonment at Fort Lafayette in New York Harbor. The Union forces captured:

• 46 artillery pieces
• 400 stands of small arms
• 60,000 pounds of gunpowder
• 2,000 Confederate troops

The Union victory at Mobile Bay secured several strategic advantages:

• Eliminated Confederate naval presence in the western Gulf Coast

• Prevented blockade runners from accessing Mobile's port facilities

• Cut off vital supply routes to Confederate forces in Tennessee Georgia

• Established a base for Union operations against Mobile proper

• Three Confederate gunboats

• The ironclad CSS Tennessee
