In the said year, and month of May, the horsemen of Florence being returned from escorting Prince Charles, with their captain, M. Amerigo di Nerbona, a host was straightway gathered against the city of Arezzo, by reason of outrages received from the Aretines, and the banners of war were given out on the 13th day of May, and the royal standard was borne by M. Gherardo Ventraia de' Tornaquinci; and so soon as they were given to them, they bore them to the abbey at Ripoli, as was their wont, and there they left them under guard, making as though they would march by that road upon the city of Arezzo. And the allies being come and the host being ordered, by secret counsel they purposed to depart by the way of Casentino, and suddenly, the 2nd day of June, the bells sounding a toll, the ever-prosperous host of the Florentines set forth, and they bore the banners which were at Ripoli across the Arno, and held the way of Pontassieve, and encamped to await the gathering of forces on Monte al Pruno; and there were assembled 1,600 horse and 10,000 foot, whereof 600 were citizens with their horses, the best armed and mounted which ever sallied forth from Florence; and 400 mercenaries, together with the following of the Captain, M.

And the said host being assembled, they descended into the plain of Casentino, devastating the places of Count Guido Novello, who was Podesta of Arezzo. Hearing this, the bishop of Arezzo, with the other captains of the Ghibelline party (for there were many men of name amongst them), determined to come with all their host to Bibbiena, to the end it might not be destroyed; and they were 800 horse and 8,000 foot, very fine men; and many wise captains of war were among them, for they were the flower of the Ghibellines of Tuscany, of the March, and of the Duchy, and of Romagna; and all were men experienced in arms and in war; and they desired to give battle to the Florentines, having no fear, albeit the Florentines were two horsemen to one against them; but they despised them, saying that they adorned themselves like women, and combed their tresses; and they derided them and held them for nought. Truly there was further cause why the Aretines should declare battle against the Florentines, albeit their horsemen were two to one against them; for they were in fear of a plot which the bishop of Arezzo had set on foot with the Florentines, and conducted by M. Marsilio de' Vecchietti, to give over to the Florentines Bibbiena, Civitella, and all the castles of his
