With the acquisition of Louisiana from Spain, Napoleon Bonaparte had begun planning a French empire in North America. But when the army he sent to crush the slave revolt in San Domingo was wiped out by war and yellow fever, Bonaparte abandoned his plans and suddenly, in 1803, offered to sell the United States all of the vast, unexplored territory of Louisiana. It was an astounding turn of events and one that probably would not have come to pass had the Quasi-War burst into something larger. Were it not for John Adams making peace with France, there might never have been a Louisiana Purchase.
