The battle had its origin in the decision of Arduin the Lombard, a Greek-speaking Lombard who had fought for the Byzantines, to change sides and form a coalition with the Normans Rainulf Drengot and the Hauteville brothers (William Iron Arm, Drogo, Humphrey), and the Lombards Atenulf of Benevento and Argyrus of Bari.
