Why was the French army finally defeated? Where was the final battle of the Haitian Revolution?

he Haitian Revolution  was a successful insurrection by self-liberated slaves against French colonial rule in Saint-Domingue, now the sovereign state of Haiti. The revolt began on 22 August 1791, and ended in 1804 with the former colony's independence. It involved blacks, mulattoes, French, Spanish, and British participants—with the ex-slave Toussaint Louverture emerging as Haiti's most charismatic hero. The revolution was the only slave uprising that led to the founding of a state which was both free from slavery, and ruled by non-whites and former captives. It is now widely seen as a defining moment in the history of the Atlantic World.
