The defeat was complete, and the loss in men very heavy, there being more than ten thousand men killed with many officers and knights of the Guelph party in Tuscany, and also many princes who had come to help them, among whom were Piero, the brother of King Ruberto, and Carlo, his nephew, and Filippo, the lord of Taranto.

On the part of Castruccio the loss did not amount to more than three hundred men, among whom was Francesco, the son of Uguccione, who, being young and rash, was killed in the first onset.
This victory so greatly increased the reputation of Castruccio that Uguccione conceived some jealousy and suspicion of him, because it appeared to Uguccione that this victory had given him no increase of power, but rather than diminished it.

Being of this mind, he only waited for an opportunity to give effect to it.

This occurred on the death of Pier Agnolo Micheli, a man of great repute and abilities in Lucca, the murderer of whom fled to the house of Castruccio for refuge.

On the sergeants of the captain going to arrest the murderer, they were driven off by Castruccio, and the murderer escaped.
