In the meantime the Italian cardinals had been insisting that Caesar also leave Rome. The Sacred College had secured about two thousand troops and had placed the city under the protection of the ambassadors of the Emperor, of Spain, France, and Venice, who—August 25th—went to Valentino, whom they found in the Vatican stretched upon a bed, but completely dressed and surrounded by the Spanish cardinals, and requested him to leave the palace. This he refused to do, saying that he was ill and that he would be safe nowhere else. Thereupon they offered him the Castle of St. Angelo for his abode. Caesar asked permission for his troops also to occupy the stronghold. He was still Duke of Romagna and he had more than nine thousand men under his command. He also had large amounts of money on deposit with Alessandro Spanocchi, consequently he was treated as a reigning prince. Both the Spanish and French ambassadors knew that his aid would be valuable in the war in Naples, and Prospero Colonna was endeavouring to persuade him to enter the service of Gonsalvo de Cordova. At the same time France was trying to secure him.
Finally, to the utter dismay of Colonna and the Spanish cardinals, he decided to cast his fortunes with the latter power, for September 1st, through the mediation of Grammont, the French ambassador, he entered into an agreement by which he was to place his troops at the service of France in the Regno and to hold himself in readiness at all times to aid the King, and to use all his influence with the Spanish cardinals to secure the election of the Cardinal of Rouen to the Papacy.
No sooner had Georges d’Amboise, Cardinal of Rouen, learned of the death of Alexander VI. than he set out in great haste for Rome, feeling certain that he could be elected to succeed the Borgia. The Papacy was the dream of his life, and he was ardently supported by the King, who would profit greatly by the election of his minister. In fact, Louis thought that if Amboise, his intimate friend, his subject, his Prime Minister, became Pope he could easily make himself master of all Italy. Amboise, with the French army under the very walls of Rome, promptly secured a strong following in the Sacred College.
By his agreement with France Caesar was assured the protection of the King both as to his person and his property. The same day—September 1st—Valentino entered into an arrangement with the Sacred College, one clause of which required him to leave Rome within three days. Prospero Colonna had also been compelled to depart, and the ambassadors of Maximilian and of Louis XII. guaranteed that while the papal throne was vacant Caesar, the Colonna, and the Spanish forces would not approach within ten miles of Rome; the orators of Venice and France did the same with respect to the French army and the Orsini.
Giustinian says it was agreed that Prospero Colonna should leave September 2nd, and Caesar, with all his artillery, the following day. Colonna did depart on the appointed day and Caesar withdrew a little later with all his troops, horse, foot, and artillery. The Duke himself was so ill that he had to be borne on a litter. The Venetian orator adds: “Now that Caesar has gone it is thought that the election will take place quietly and without any disturbance, since every one respects the Sacred College.” Still, some uneasiness was felt lest the French should cause a disturbance, because Odoardo Bugliotto, the King’s valet, had arrived with a large amount of money, determined to make the Cardinal of Rouen Pope. Monsignor de Trans had told Giustinian that neither Ascanio Sforza nor any of the other cardinals then in France would attend the conclave, “nevertheless, yesterday evening the report was circulated, and this morning it was confirmed, that Amboise, Sforza, San Malo, and Aragona[27] were already on the way, and,” he adds, “if this is true there will be much intriguing, for these men are seditious and shameless and with their astuteness and machinations cause much disturbance, and may God in his mercy watch over Christendom.”
The same day—September 2nd—Giustinian informs his Government: “It is learned that Valentino, without the knowledge of any one, has entered into an agreement with France.”
Prospero Colonna was greatly chagrined by Caesar’s last trick, and when he left Rome he took with him the Princess of Squillace—“who will be some comfort to him—while the Prince went with the Duke. The Princess departed willingly, hoping to recover her estates in the Regno—in any event there is little love between her and her husband as they are entirely unlike.” Owing to the trouble and discord she had occasioned in the family, the Princess Sancia had been imprisoned by Alexander VI. in the Castle of St. Angelo.
Burchard describes Valentino’s departure in detail. The very morning of the agreement he paid his troops and sent thirteen heavy wagons laden with engines of war forward through Trastevere. He had three large bombards, two medium, and eight small ones. Then he dispatched his guard to the Milvius Bridge, there to await him. More than a hundred wagons were required for his baggage. They left the Vatican by the Viridaria Gate and proceeded to Monte Mario, the Duke borne on a litter by twelve halberdiers. After him was led a magnificent charger with trappings of black velvet, embroidered with his arms and the ducal crown.
The Spanish and French ambassadors accompanied him as far as the city gate. Caesar set out for Nepi, a town belonging to his family, the citadel of which was still loyal to him. Gregorovius says his mother Vannozza and his brother Giuffre accompanied him.
Valentino was still a power to be reckoned with, and he undoubtedly hoped to secure the election of a Pope who would be friendly to himself and the Borgia family, for he knew that he could count on the votes of the eleven Spanish cardinals.
