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.
