In the meantime the pope died. Corso, with the other citizens, returned from Rome; and all would have been well if his restless mind had not occasioned new troubles. It was his common practice to be of a contrary opinion to the most powerful men in the city; and whatever he saw the people inclined to do, he exercised his utmost influence to effect, in order to attach them to himself; so that he was a leader in all differences, at the head of every new scheme, and whoever wished to obtain anything extraordinary had recourse to him. This conduct caused him to be hated by many of the highest distinction; and their hatred increased to such a degree that the Neri faction to which he belonged, became completely divided; for Corso, to attain his ends, had availed himself of private force and authority, and of the enemies of the state. But so great was the influence attached to his person, that everyone feared him. Nevertheless, in order to strip him of the popular favor (which by this means may easily be done), a report was set on foot that he intended to make himself prince of the city; and to the design his conduct gave great appearance of probability, for his way of living quite exceeded all civil bounds; and the opinion gained further strength, upon his taking to wife a daughter of Uguccione della Faggiuola, head of the Ghibelline and Bianchi faction, and one of the most powerful men in Tuscany.
When this marriage became known it gave courage to his adversaries, and they took arms against him; for the same reason the people ceased to defend him, and the greater part of them joined the ranks of his enemies, the leaders of whom were Rosso della Tosa, Pazino dei Pazzi, Geri Spini, and Berto Brunelleschi. These, with their followers, and the greater part of the people, assembled before the palace of the Signory, by whose command a charge was made before Piero Branca, captain of the people, against Corso, of intending, with the aid of Uguccione, to usurp the government. He was then summoned, and for disobedience, declared a rebel; nor did two hours pass over between the accusation and the sentence. The judgment being given, the Signory, with the companies of the people under their ensigns, went in search of him, who, although seeing himself abandoned by many of his followers, aware of the sentence against him, the power of the Signory, and the multitude of his enemies, remained undaunted, and fortified his houses, in the hope of defending them till Uguccione, for whom he had sent, should come to his Relief. His residences, and the streets approaching them, were barricaded and taken possession of by his partisans, who defended them so bravely that the enemy, although in great numbers, could not force them, and the battle became one of the hottest, with wounds and death on all sides. But the people, finding they could not drive them from their ground, took possession of the adjoining houses, and by unobserved passages obtained entry. Corso, thus finding himself surrounded by his foes, no longer retaining any hope of assistance from Uguccione, and without a chance of victory, thought only of effecting his personal safety, and with Gherardo Bordoni, and some of his bravest and most trusted friends, fought a passage through the thickest of their enemies, and effected their escape from the city by the Gate of the Cross. They were, however, pursued by vast numbers, and Gherardo was slain upon the bridge of Affrico by Boccaccio Cavicciulli. Corso was overtaken and made prisoner by a party of Catalan horse, in the service of the Signory, at Rovezzano. But when approaching Florence, that he might avoid being seen and torn to pieces by his victorious enemies, he allowed himself to fall from horseback, and being down, one of those who conducted him cut his throat. The body was found by the monks of San Salvi, and buried without any ceremony due to his rank. Such was the end of Corso, to whom his country and the Neri faction were indebted for much both of good and evil; and if he had possessed a cooler spirit he would have left behind him a more happy memory.
Nevertheless, he deserves to be enumerated among the most distinguished men our city has produced. True it is, that his restless conduct made both his country and his party forgetful of their obligation to him. The same cause also produced his miserable end, and brought many troubles upon both his friends and his country.
Uguccione, coming to the assistance of his relative, learned at Remoli that Corso had been overcome by the people, and finding that he could not render him any assistance, in order to avoid bringing evil upon himself without occasion, he returned home.
