But the Florentines, though they had sent no help to Guglielmo dei Pazzi, had demanded aid from Chaumont d’Amboise, governor of the Milanese, on behalf of Louis XII, not only explaining the danger they themselves were in but also Caesar’s ambitious projects, namely that after first overcoming the small principalities and then the states of the second order, he had now, it seemed, reached such a height of pride that he would attack the King of France himself. The news from Naples was disquieting; serious differences had already occurred between the Count of Armagnac and Gonzalva di Cordova, and Louis might any day need Florence, whom he had always found loyal and faithful. He therefore resolved to check Caesar’s progress, and not only sent him orders to advance no further step forwards, but also sent off, to give effect to his injunction, the captain Imbaut with 400 lances. The Duke of Valentinois on the frontier of Tuscany received a copy of the treaty signed between the republic and the King of France, a treaty in which the king engaged to help his ally against any enemy whatsoever, and at the same moment the formal prohibition from Louis to advance any further. Caesar also learned that beside the 400 lances with the captain Imbaut, which were on the road to Florence, Louis XII had as soon as he reached Asti sent off to Parma Louis de la Trimouille and 200 men-at-arms, 3000 Swiss, and a considerable train of artillery. In these two movements combined he saw hostile intentions towards himself, and turning right about face with his usual agility, he profited by the fact that he had given nothing but verbal instructions to all his lieutenants, and wrote a furious letter to Vitellozzo, reproaching him for compromising his master with a view to his own private interest, and ordering the instant surrender to the Florentines of the towns and fortresses he had taken, threatening to march down with his own troops and take them if he hesitated for a moment. As soon as this letter was written, Caesar departed for Milan, where Louis XII had just arrived, bringing with him proof positive that he had been calumniated in the evacuation of the conquered towns. He also was entrusted with the pope’s mission to renew for another eighteen months the title of legate ’a latere’ in France to Cardinal d’Amboise, the friend rather than the minister of Louis XII. Thus, thanks to the public proof of his innocence and the private use of his influence, Caesar soon made his peace with the King of France.
