L' Overture skillfully led a group of angry ex-slaves against French troops in Santo Domingo. The French were unable to reconquer this valuable island and hence, had no use for Louisiana to serve as a granary for Santo Domingo. The inability of the French to regain possession of the island caused Napoleon to cede the Louisiana territory to the United States for 15 million dollars. Thus, Toussaint L' Overture's military vigor indirectly provoked Napoleon's decision to sell Louisiana to the Americans.
