But that possession had become more precious to the sovereign of Spain, who refused the proffers that France was able to make in the next thirty years. The dream of repossession became fonder to the French republic. Talleyrand, who had spent a year in travel in the United States, urged the acquisition not merely for France's own sake but to curb the ambitions of the Americans, "whose conduct ever since the moment of their independence is enough to prove this truth: the Americans are devoured by pride, ambition, and cupidity." "There are," he said, "no other means of putting an end to the ambition of the Americans than that of shutting them up within the limits which nature seems to have traced for them; but Spain is not in a condition to do this great work alone. She cannot, therefore, hasten too quickly to engage the aid of a preponderating power, yielding to it a small part of her immense domains in order to preserve the rest." "Let the court of Madrid cede these districts to France and from that moment the power of America is bounded by the limit which it may suit the interests and the tranquillity of France and Spain to assign her. The French Republic ... will be a wall of brass forever impenetrable to the combined efforts of England and America."

It contemplated at first the occupation of Santo Domingo, the quelling of the insurrection there, then the seizure of Louisiana, already promised to France by Spain, then the acquisition of Florida, the conversion of the Gulf of Mexico into a French lake, and ultimately the extension of the province of Louisiana to the Alleghanies and, perhaps, even to the old borders of New France along the Great Lakes and the St. Lawrence. But plague and slaughter met his armies in Santo Domingo in the first step toward the realization of his vast design, and the vision, in the shifting light of events in Europe and on the shores of America as well, soon assumed other shape and color and at last disappeared entirely, supplanted by the vision of a strengthened American republic that would come to be a rival of England. This was what came (in his own language) instead of his dream of a New France beyond the Mississippi, beyond the American republic:
