The two fleets meet in near Byzantium, Cleitus wins a victory in which some 70 ships of Nicanor are captured, sunk or disabled, the remnant excaping to Chalcedon, where they are joined by Antigonus and his army. Antigonus orders the remaining 60 ships to be readied for renewed action, and assigns his strongest and most loyal soldiers as marines to these ships. Meanwhile, the Byzantines transport his archers, slingers and peltast to the European shore, where Cleitus's victorious forces were encamped.
