people, he was attacked and assaulted at the palace, the archbishop giving the people to understand that he had betrayed Pisa, and given up their fortresses to the Florentines and the Lucchese; and being without any defence, the people having turned against him, he surrendered himself prisoner, and at the said assault one of his bastard sons and one of his grandsons were slain, and Count Ugolino was taken, and two of his sons, and three grandsons, his son's children, and they were put in prison; and his household and followers, and the Visconti and Ubizinghi, Guatani, and all the other Guelf houses were driven out of Pisa. And thus was the traitor betrayed by the traitor; wherefore the Guelf party in Tuscany was greatly cast down, and the Ghibellines greatly exalted because of the said revolution in Pisa, and because of the force of the Ghibellines of Arezzo, and because of the power and victories of Don James of Aragon, and of the Sicilians against the heirs of King Charles.
