The 1781 Siege: Bernardo de Gálvez and the Battle That Helped Win the Revolution
Near Pensacola, Florida
Most Americans have never heard of Bernardo de Gálvez, yet he may have done more to win the American Revolution in the South than any single commander on the continent.
When Spain entered the war against Britain in seventeen seventy-nine, Gálvez, the thirty-two-year-old governor of Spanish Louisiana, immediately went on offense. He swept down the lower Mississippi, captured Fort Bute and Baton Rouge in seventeen seventy-nine, then took Mobile in seventeen eighty. Pensacola was next, and it was the strategic prize that crowned the whole campaign.
Pensacola was the capital of British West Florida and guarded by nearly two thousand regulars and loyalist militia. Gálvez arrived with a fleet in March seventeen eighty-one, but a violent storm wrecked several of his ships in the bay approaches and forced a temporary retreat. He regrouped and returned with reinforcements that swelled his force to nearly eight thousand men.
The British artillery held the advantage until May eighth, seventeen eighty-one. A Spanish shell struck a powder magazine inside the Queen's Redoubt on the high ground above the fort. The explosion killed roughly sixty soldiers and demolished the fortification. The British position collapsed. Two days later, on May tenth, the British garrison surrendered the entire city.
The strategic effect was immediate and significant. Britain lost its last major foothold on the Gulf of Mexico. Spain now controlled the entire Gulf Coast from New Orleans to the Florida Keys. British forces that might have threatened American positions from the southwest were permanently tied down.
Gálvez never fought alongside Washington, never set foot in the thirteen colonies. But he bled British strength from a direction Americans could not cover themselves. When the Paris peace treaty was signed in seventeen eighty-three, the United States won its independence partly because Spain had won Pensacola.
The site of Fort Barrancas, where that magazine exploded, is preserved today within Gulf Islands National Seashore, a short drive from here.
