1259 — Battle of Cassano (1259)

The Battle of Cassano was fought in the Autumn of 1259 between Guelph and Ghibelline armies in Northern Italy. In 1259, Ezzelino da Romano and his Ghibelline army moved into Lombardy and besieged Orci Novi. However, the approach of the Guelph army forced Ezzelino to abandon the siege and cross the Oglio River. Joined by exiled nobles from Milan, the Ghibellines attempted to take the city of Monza by force but failed.
