The Battle of Càscina was an engagement between Pisan and Florentine troops on 28 July 1364 near Càscina, Italy. Florence's victory followed a recent defeat to Pisan forces that had enabled mercenary John Hawkwood, who was in command of the Pisan army, to occupy the Valdinievole, Prato en route to Florence. Hawkwood and his army looted the lucrative Mugello region and Pistoia before proceeding towards Florence. Hawkwood fought alongside Hanneken von Baumgarten and had 3000 men-at-arms at his disposal.
