The Battle of Montecatini was fought in the Val di Nievole on August 29, 1315 between the Republic of Pisa, and the forces of both Kingdom of Naples and Republic of Florence. The army of Pisa, commanded by Uguccione della Faggiuola, won a decisive victory despite being outnumbered. The Neapolitan forces, made up of nearly 60,000 men, were commanded by Philip I of Taranto. While he survived the battle, his eldest son Charles of Taranto and his brother Peter, Count of Eboli and Gravina, were both killed in the fight. Additional deaths included members of 114 Florentine noble families, as well as Francesco della Faggiuola, son of Uguccione.
