When they left Piombino, the pope and his son visited the island of Elba, where they only stayed long enough to visit the old fortifications and issue orders for the building of new ones.
Then the illustrious travellers embarked on their return journey to Rome; but scarcely had they put out to sea when the weather became adverse, and the pope not wishing to put in at Porto Ferrajo, they remained five days on board, though they had only two days' provisions. During the last three days the pope lived on fried fish that were caught under great difficulties because of the heavy weather. At last they arrived in sight of Corneto, and there the duke, who was not on the same vessel as the pope, seeing that his ship could not get in, had a boat put out, and so was taken ashore. The pope was obliged to continue on his way towards Pontercole, where at last he arrived, after encountering so violent a tempest that all who were with him were utterly subdued either by sickness or by the terror of death. The pope alone did not show one instant's fear, but remained on the bridge during the storm, sitting on his arm-chair, invoking the name of Jesus and making the sign of the cross. At last his ship entered the roads of Pontercole, where he landed, and after sending to Corneto to fetch horses, he rejoined the duke, who was there awaiting him. They then returned by slow stages, by way of Civita Vecchia and Palo, and reached Rome after an absence of a month. Almost at the same time d'Albret arrived in quest of his cardinal's hat. He was accompanied by two princes of the house of Navarre, who were received with not only those honours which beseemed their rank, but also as brothers-in-law to whom the, duke was eager to show in what spirit he was contracting this alliance.
CHAPTER XIII
The time had now come for the Duke of Valentinois to continue the pursuit of his conquests. So, since on the 1st of May in the preceding year the pope had pronounced sentence of forfeiture in full consistory against Julius Caesar of Varano, as punishment for the murder of his brother Rudolph and for the harbouring of the pope's enemies, and he had accordingly been mulcted of his fief of Camerino, which was to be handed over to the apostolic chamber, Caesar left Rome to put the sentence in execution. Consequently, when he arrived on the frontiers of Perugia, which belonged to his lieutenant, Gian Paolo Baglioni, he sent Oliverotta da Fermo and Orsini of Gravina to lay waste the March of Camerino, at the same time petitioning Guido d'Ubaldo di Montefeltro, Duke of Urbino, to lend his soldiers and artillery to help him in this enterprise. This the unlucky Duke of Urbino, who enjoyed the best possible relations with the pope, and who had no reason for distrusting Caesar, did not dare refuse. But on the very same day that the Duke of Urbina's troops started for Camerino, Caesar's troops entered the duchy of Urbino, and took possession of Cagli, one of the four towns of the little State. The Duke of Urbino knew what awaited him if he tried to resist, and fled incontinently, disguised as a peasant; thus in less than eight days Caesar was master of his whole duchy, except the fortresses of Maiolo and San Leone.
The Duke of Valentinois forthwith returned to Camerino, where the inhabitants still held out, encouraged by the presence of Julius Caesar di Varano, their lord, and his two sons, Venantio and Hannibal; the eldest son, Gian Maria, had been sent by his father to Venice.
The presence of Caesar was the occasion of parleying between the besiegers and besieged. A capitulation was arranged whereby Varano engaged to give up the town, on condition that he and his sons were allowed to retire safe and sound, taking with them their furniture, treasure, and carriages. But this was by no means Caesar's intention; so, profiting by the relaxation in vigilance that had naturally come about in the garrison when the news of the capitulation had been announced, he surprised the town in the night preceding the surrender, and seized Caesar di Varano and his two sons, who were strangled a short time after, the father at La Pergola and the sons at Pesaro, by Don Michele Correglio, who, though he had left the position of sbirro for that of a captain, every now and then returned to his first business.
Meanwhile Vitellozzo Vitelli, who had assumed the title of General of the Church, and had under him 800 men-at-arms and 3,000 infantry, was following the secret instructions that he had received from Caesar by word of mouth, and was carrying forward that system of invasion which was to encircle Florence in a network of iron, and in the end make her defence an impossibility. A worthy pupil of his master, in whose school he had learned to use in turn the cunning of a fox and the strength of a lion, he had established an understanding between himself and certain young gentlemen of Arezzo to get that town delivered into his hands. But the plot had been discovered by Guglielma dei Pazzi, commissary of the Florentine Republic, and he had arrested two of the conspirators, whereupon the others, who were much more numerous than was supposed; had instantly dispersed about the town summoning the citizens to arms. All the republican faction, who saw in any sort of revolution the means of subjugating Florence, joined their party, set the captives at liberty, and seized Guglielmo; then proclaiming the establishment of the ancient constitution, they besieged the citadel, whither Cosimo dei Pazzi, Bishop of Arezzo, the son of Guglielmo, had fled for refuge; he, finding himself invested on every side, sent a messenger in hot haste to Florence to ask for help.
Unfortunately for the cardinal, Vitellozzo's troops were nearer to the besiegers than were the soldiers of the most serene republic to the besieged, and instead of help—the whole army of the enemy came down upon him. This army was under the command of Vitellozzo, of Gian Paolo Baglioni, and of Fabio Orsino, and with them were the two Medici, ever ready to go wherever there was a league against Florence, and ever ready at the command of Borgia, on any conditions whatever, to re-enter the town whence they had been banished. The next day more help in the form of money and artillery arrived, sent by Pandolfo Petrucci, and on the 18th of June the citadel of Arezzo, which had received no news from Florence, was obliged to surrender.
Vitellozzo left the men of Arezzo to look after their town themselves, leaving also Fabio Orsina to garrison the citadel with a thousand men. Then, profiting by the terror that had been spread throughout all this part of Italy by the successive captures of the duchy of Urbino, of Camerino, and of Arezzo, he marched upon Monte San Severino, Castiglione, Aretino, Cortone, and the other towns of the valley of Chiana, which submitted one after the other almost without a struggle. When he was only ten or twelve leagues from Florence, and dared not an his own account attempt anything against her, he made known the state of affairs to the Duke of Valentinois. He, fancying the hour had came at last far striking the blow so long delayed, started off at once to deliver his answer in person to his faithful lieutenants.
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
