King Charles being in Tuscany, the Ghibelline refugees from Florence formed themselves into a league and company with the Pisans and Sienese, and came to an agreement with Don Henry of Spain, which was Roman senator, and already at enmity with King Charles, his cousin. Therefore, with certain barons of Apulia and Sicily, he made oath and conspiracy to make certain towns in Sicily and in Apulia to rebel, and to send into Germany, and to stir up Conradino, which was the son of Conrad, the son of the Emperor Frederick, to cross into Italy to take away Sicily and the Kingdom from King Charles. And so it was done; for immediately in Apulia there rose in rebellion Nocera of the Saracens, and Aversa in Terra di Lavoro, and many places in Calabria, and almost all in Abruzzi, if we except Aquila, and in Sicily almost all, or a great part of the island of Sicily, if we except Messina and Palermo; and Don Henry caused Rome to rebel, and all Campagna and the country around; and the Pisans and the Sienese and the other Ghibelline cities sent of their money 100,000 golden florins to stir up the said Conradino, who being very young, sixteen years old, set forth from Germany, against his mother's will, who was daughter of the duke of Austria, and who was not willing for him to depart because of his youth. And he came to Verona in the month of February, in the year of Christ 1267, with many barons and good men-at-arms from Germany in his train; and it is said that there followed him as far as Verona nigh upon 10,000 men on horses or ponies, but through lack of means a great part returned to Germany, yet there remained of the best 3,500 German cavalry. And from Verona he passed through Lombardy, and by the way of Pavia he came to the coast of Genoa, and arrived beyond Saona at the shores of Varagine, and there put out to sea, and by means of the forces of the Genoese, with their fleet of twenty-five galleys, came by sea to Pisa, and arrived there in May in 1268, and by the Pisans and by all the Ghibellines of Italy was received with great honour, almost as if he had been Emperor. His cavalry came by land, crossing the mountains of Pontremoli, and arrived at Serrazzano, which was held by the Pisans, and then took the way of the seacoast with an escort as far as Pisa. King Charles, hearing how Conradino was come into Italy, and hearing of the rebellion of his cities in Sicily and Apulia, caused by the treacherous barons of the Kingdom (the most of whom he had released from prison), and by Don Henry of Spain, immediately departed from Tuscany, and by hasty marches came into Apulia, and left in Tuscany M. William di Belselve, his marshal, and with him M. William, the standard-bearer, with 800 French and Provencal horsemen to keep the cities of Tuscany for his party, and to oppose Conradino so that he should not be able to pass. And Pope Clement, hearing of the coming of Conradino, sent to him his messengers and legates,
