Napoleon lost another 50,000 men to disease (yellow fever) in Haiti. He sent them there with the intention of using it as a staging area for militarizing the Louisiana Territory. There was a slave revolt, and in the process he lost not only most of his army, but Haiti as well. He gave up his North American ambitions, and offered President Jefferson a chance to buy the Louisiana Territory, doubling the size of the USA.

"An army travels on its stomach." When it can no longer stand, I guess.

Napoleon knew that France and Britain were weeks away from resuming their war, and sold Louisiana to the U.S. because he knew as a French colony it would fall to the British easily. A fire sale, as it were.

1803:
30 April: Napoleon sells Louisiana to United States.
18 May: Britain declares war.
