 The Romans would later be able to use this weakness against the phalanx as their more mobile maniples could withstand the pressure of the phalanx longer than more traditional formations, thus earning valuable time for their wings to outflank it, as at Cynoscephalae and Magnesia, or for the phalanx to lose its cohesion due to prolonged movement forward or advancement through unfavorable terrain, as at Pydna.Yet, regardless of the many Roman victories against the Hellenistic Kingdoms, the legion never won against a phalanx by frontal assault.Even at Pydna, it took the strange withdrawal of the Macedonian cavalry for the Romans to finally outflank the phalanx and claim a bloody victory.
