Thus at last the bargain was put in shape. The French government held out the hope of giving Tuscany as the equivalent for Louisiana and six seventy-fours. If not Tuscany, the three legations, or their equivalent, were stipulated. The suggestion of Tuscany delighted the King and Queen. Thus far the secret was confined to the parties directly interested; but after the principle had been fixed, another person was intrusted with it. The Prince of Peace was suddenly called to the Palace by a message marked “luego, luego, luego!”--the sign of triple haste.[107] He found Don Carlos in a paroxysm of excitement; joy sparkled in his eyes. “Congratulate me,” he cried, “on this brilliant beginning of Bonaparte’s relations with Spain! The Prince-presumptive of Parma, my son-in-law and nephew, a Bourbon, is invited by France to reign, on the delightful banks of the Arno, over a people who once spread their commerce through the known world, and who were the controlling power of Italy,--a people mild, civilized, full of humanity; the classical land of science and art!” The Prince of Peace could only offer congratulations; his opinion was asked without being followed, and a few days later the treaty was signed.[108] On the last day of September, 1800, Joseph Bonaparte signed the so-called Treaty of Morfontaine, which restored relations between France and the United States. The next day, October 1, Berthier signed at San Ildefonso the treaty of retrocession, which was equivalent to a rupture of the relations established four-and-twenty hours earlier. Talleyrand was aware that one of these treaties undid the work of the other. The secrecy in which he enveloped the treaty of retrocession, and the pertinacity with which he denied its existence showed his belief that Bonaparte had won a double diplomatic triumph over the United States. Moreau’s great victory at Hohenlinden, December 3, next brought Austria to her knees. Joseph Bonaparte was sent to Lunéville in Lorraine, and in a few weeks negotiated the treaty which advanced another step the cession of Louisiana. The fifth article of this treaty, signed Feb. 9, 1801, deprived the actual Grand Duke of his Grand Duchy, and established the young Duke of Parma in Tuscany. To complete the transaction, Lucien Bonaparte was sent as ambassador to Madrid.
