The Americans were sure to overrun it long before he could get an army there—if he ever could. “Sixty million francs for an occupation that will not perhaps last a day!” he exulted. He knew what he was giving up and what the United States was getting—and the benefit to France, beyond the money: “The sale assures forever the power of the United States, and I have given England a rival who, sooner or later, will humble her pride.”17
