Battle of Pydna 22 June 168 BC
This battle in the Third Macedonian War 172-167BC saw the destruction of the Macedonian Army and Rome establish a virtual protectorate over Greece. The Macedonian Phalanx under King Persus at first was successful pushing the Roman Legions under Lucius Aemilius Paulus back but then became disordered after entering broken ground. The Roman Legionaries counter attacked opening gaps in the phalanx and killing at least 20,000 phalangites and capturing another 10,000. The battle like the battle of Cynoscephalae showed that the legion's tactical flexibility was lethal against the slow moving and unwieldy phalanx.
