November 18 in Military History — On This Day

Battle of Vertières

On November 18, 1803, on a hillside outside Cap-Français (the colonial capital), Dessalines's revolutionary army fought the last major battle of the Haitian Revolution against the battered remnants of Rochambeau's French force. The battle was fierce: French cannon fire was intense, and the Haitian commander François Capois had his horse shot from under him, stood up in the open, and kept advancing — a moment of such audacity that even the French reportedly paused to applaud before resuming fire. The Haitian forces overwhelmed the French positions over the course of the day. Three weeks after Vertières, Rochambeau formally surrendered Cap-Français to the British navy rather than to Dessalines — one final act of racial contempt — and was evacuated with his surviving men.

Vertières was the decisive military engagement that ended French rule in Saint-Domingue. Coming less than two years after Napoleon had sent an 80,000-man expedition to reconquer the colony, the battle demonstrated the complete failure of French arms in the Caribbean. Napoleon, already at war in Europe, abandoned his American empire — selling Louisiana to the United States just months earlier. The Haitian victory at Vertières made the Louisiana Purchase possible.
