But the Florentines, though they had sent no help to Guglielmo dei Pazzi, had demanded aid from Chaumont dumbest, governor of the Milanese, an 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 Valentinais 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 dumbest, 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.
But this was not all.It was in the nature of Caesar's genius to divert an impending calamity that threatened his destruction so as to come out of it better than before, and he suddenly saw the advantage he might take from the pretended disobedience of his lieutenants.
Already he had been disturbed now and again by their growing power, and coveted their towns, now he thought the hour had perhaps came for suppressing them also, and in the usurpation of their private possessions striking a blow at Florence, who always escaped him at the very moment when he thought to take her.It was indeed an annoying thing to have these fortresses and towns displaying another banner than his own in the midst of the beautiful Romagna which he desired far his own kingdom.For Vitellozzo possessed Citta di Castello, Bentivoglio Bologna, Gian Paolo Baglioni was in command of Perugia, Oliverotto had just taken Fermo, and Pandolfo Petrucci was lord of Siena; it was high time that all these returned: into his own hands.The lieutenants of the Duke of Valentinois, like Alexander's, were becoming too powerful, and Borgia must inherit from them, unless he were willing to let them become his own heirs.He obtained from Louis XII three hundred lances wherewith to march against them.As soon as Vitellozzo Vitelli received Caesar's letter he perceived that he was being sacrificed to the fear that the King of France inspired;but he was not one of those victims who suffer their throats to be cut in the expiation of a mistake: he was a buffalo of Romagna who opposed his horns to the knife of the butcher; besides, he had the example of Varano and the Manfredi before him, and, death for death, he preferred to perish in arms.
So Vitellozzo convoked at Maggione all whose lives or lands were threatened by this new reversal of Caesar's policy.These were Paolo Orsino, Gian Paolo Baglioni, Hermes Bentivoglio, representing his father Gian, Antonio di Venafro, the envoy of Pandolfo Petrucci, Olivertoxo da Fermo, and the Duke of Urbino: the first six had everything to lose, and the last had already lost everything.
A treaty of alliance was signed between the confederates: they engaged to resist whether he attacked them severally or all together.
Caesar learned the existence of this league by its first effects: the Duke of Urbino, who was adored by his subjects, had come with a handful of soldiers to the fortress of San Leone, and it had yielded at once.In less than a week towns and fortresses followed this example, and all the duchy was once more in the hands of the Duke of Urbino.
At the same time, each member of the confederacy openly proclaimed his revolt against the common enemy, and took up a hostile attitude.
