Saint-Domingue expedition

The Saint-Domingue expedition was a large French military invasion sent by Napoleon Bonaparte, then First Consul, under his brother-in-law Charles Victor Emmanuel Leclerc in an attempt to regain French control of the Caribbean colony of Saint-Domingue on the island of Hispaniola, and curtail the measures of independence and abolition of slaves taken by the former slave Toussaint Louverture. It departed in December 1801 and, after initial success, ended in a French defeat at the Battle of Vertières and the departure of French troops in December 1803.
