Battle of Baton Rouge

Spanish Governor Bernardo de Gálvez defeated the British garrison at Baton Rouge as part of Spain's war against Britain following Spain's entry into the conflict in June 1779. De Gálvez had assembled about 1,400 men — Spanish regulars, militia, free Black soldiers, and Choctaw and Chickasaw warriors — and marched from New Orleans to attack the British posts in West Florida.

De Gálvez employed an effective deception: while the main British fortification at Baton Rouge was strong, he drew British attention to a false battery position with noisy construction, then quickly emplaced his real battery under cover. The sudden appearance of accurate Spanish artillery fire at close range panicked the garrison, which surrendered after a brief bombardment. The British commander Alexander Dickson surrendered not only Fort New Richmond at Baton Rouge but also Fort Panmure at Natchez, doubling the prize.

De Gálvez's campaign on the Gulf Coast and in West Florida — including the eventual capture of Pensacola in 1781 — demonstrated that Spain's intervention significantly expanded the scope of the war against Britain. His operations protected the American southern flank and prevented the British from using the Gulf Coast as a base for operations against the Continental Army, making him one of the unsung strategic contributors to American independence.
