 With the loss of Volterra, Florentine hopes of opening a supply line into the city dwindled, and Florence looked to the arrival of Ferruccio with a relief army, which he had gathered around Pisa.Orange, having arranged that Baglioni would not attack the Imperial forces in his absence, marched out with the larger portion of his army to intercept him.On 3 August 1530 the two armies met at the Battle of Gavinana; both Orange and Ferruccio were killed, and the Florentine forces were decisively defeated.
