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.
