Braccio of Perugia, whom we have frequently mentioned as one of the most distinguished warriors of Italy, left two sons, Oddo and Carlo; the latter was of tender years; the former, as above related, was slain by the people of Val di Lamona; but Carlo, when he came to mature age, was by the Venetians, out of respect for the memory of his father, and the hopes they entertained from himself, received among the condottieri of their republic. The term of his engagement having expired, he did not design to renew it immediately, but resolved to try if, by his own influence and his father's reputation, he could recover possession of Perugia. To this the Venetians willingly consented, for they usually extended their dominion by any changes that occurred in the neighboring states. Carlo consequently came into Tuscany, but found more difficulties in his attempt upon Perugia than he had anticipated, on account of its being allied with the Florentines; and desirous of doing something worthy of memory, he made war upon the Siennese, alleging them to be indebted to him for services performed by his father in the affairs of that republic, and attacked them with such impetuosity as to threaten the total overthrow of their dominion. The Siennese, ever ready to suspect the Florentines, persuaded themselves that this outrage had been committed with their cognizance, and made heavy complaints to the pope and the king against them. They also sent ambassadors to Florence to complain of the injuries they had suffered, and adroitly intimated, that if Carlo had not been secretly supported he could not have made war upon them with such perfect security. The Florentines denied all participation in the proceedings of Carlo, expressed their most earnest wish to do everything in their power to put a stop to them, and allowed the ambassadors to use whatever terms they pleased in the name of the Signory, to command him to desist. Carlo complained that the Florentines, by their unwillingness to support him, had deprived themselves of a most valuable acquisition and him of great glory; for he could have insured them the possession of the whole territory in a short time, from the want of courage in the people and the ineffectual provision they had made for their defense. He then withdrew to his engagement under the Venetians; but the Siennese, although delivered from such imminent peril by the Florentines, were still very indignant against them; considering themselves under no obligation to those who had delivered them from an evil to which they had first exposed them.
