The people of Florence having taken the ill resolve to raise an army, craved assistance from their friends, which came with foot soldiers and with horse, from Lucca, and Bologna, and Pistoia, and Prato, and Volterra, and Samminiato, and Sangimignano, and from Colle di Valdelsa, which were in league with the commonwealth and people of Florence; and in Florence there were 800 horsemen of the citizens and more than 500 mercenaries. And the said people being assembled in Florence, the host set forth in the end of August, and for pomp and display they led out the carroccio, and a bell, which they called Martinella, on a car with a wooden tower on wheels, and there went out nearly all the people with the banners of the guilds, and there did not remain a house or a family in Florence which went not forth on foot or on horseback, at least one for each house, and for some two or more, according to their power. And when they found themselves in the territory of Siena, at the place agreed upon, on the river Arbia, at the place called Montaperti, with the men of Perugia and of Orvieto, which there joined with the Florentines, there were gathered together more than 3,000 horse and more than 30,000 foot. And whilst the host of the Florentines was thus preparing, the aforesaid framers of the plot, which were in Siena, in order that it might be the more fully accomplished, sent to Florence certain other friars to hatch treason with certain Ghibelline magnates and popolani which had not been exiled from Florence, and would therefore have to join the general muster of the army. With these, then, they plotted that when they were drawn up for battle, they should from divers quarters flee from their companies, and repair to their own party, to confound the Florentine army. And this plot they made because they seemed to themselves to be but few in comparison with the Florentines; and so it was done. [Sidenote: Inf. xxxii. 78-111.] [Sidenote: Inf. x. 85-87.]
