It was, then, a revival of an earlier idea when President Jefferson, officially through Robert R. Livingston, Minister to France, and unofficially through a French gentleman, Dupont de Nemours, sought to impress upon the First Consul the unwisdom of his taking possession of Louisiana, without ceding to the United States at least New Orleans and the Floridas as a "palliation." Even so, France would become an object of suspicion, a neighbor with whom Americans were bound to quarrel.
Undeterred by this naive threat, doubtless considering its source, the First Consul pressed Don Carlos for the delivery of Louisiana. The King procrastinated but at length gave his promise on condition that France should pledge herself not to alienate the province. Of course, replied the obliging Talleyrand. The King's wishes were identical with the intentions of the French government. France would never alienate Louisiana. The First Consul pledged his word. On October 15, 1802, Don Carlos signed the order that delivered Louisiana to France.
While the President was anxiously awaiting the results of his diplomacy, news came from Santo Domingo that Leclerc and his army had triumphed over Toussaint and his faithless generals, only to succumb to a far more insidious foe. Yellow fever had appeared in the summer of 1802 and had swept away the second army dispatched by Bonaparte to take the place of the first which had been consumed in the conquest of the island. Twenty-four thousand men had been sacrificed at the very threshold of colonial empire, and the skies of Europe were not so clear as they had been. And then came the news of Leclerc's death (November 2, 1802). Exhausted by incessant worry, he too had succumbed to the pestilence; and with him, as events proved, passed Bonaparte's dream of colonial empire in the New World.
Almost at the same time with these tidings a report reached the settlers of Kentucky and Tennessee that the Spanish intendant at New Orleans had suspended the right of deposit. The Mississippi was therefore closed to western commerce. Here was the hand of the Corsican.* Now they knew what they had to expect from France. Why not seize the opportunity and strike before the French legions occupied the country? The Spanish garrisons were weak; a few hundred resolute frontiersmen would speedily overpower them.
