Battle of Cynoscephalae: Roman Legion Breaks Macedonian Phalanx

In early summer 197 BC, the Roman army under Titus Quinctius Flamininus defeated the Macedonian phalanx of Philip V at Cynoscephalae in Thessaly. The battle pitted the flexible Roman legion against the rigid Macedonian phalanx, which had dominated warfare since Alexander the Great. After a foggy skirmish escalated, Philip's right wing pushed back the Roman left, but Flamininus' right wing, led by war elephants, routed the unprepared Macedonian left. An unnamed Roman tribune then led 20 maniples from the right to attack the phalanx's vulnerable flank and rear, causing a massacre. Philip fled, losing about 8,000 killed and 5,000 captured; Roman losses were around 700. The victory established Roman supremacy over Greece. Philip was forced to abandon Greek possessions but later helped Rome in the Seleucid War. Flamininus declared Greek freedom, though it was short-lived. The battle demonstrated the phalanx's inflexibility compared to the legion's adaptability, a lesson later analyzed by historian Polybius.
