According to the Greek historian Herodotus, the Persian general Mardonius used horse archers to attack and harass his opponents during the Battle of Plataea, which was won by the Greeks. Philip of Macedon scored an epic victory against the Scythians residing north of the Danube, killing their king, Ateas, and causing their kingdom to fall apart thereafter. Alexander the Great defeated Scythians/Sakas in 329 BC at the Battle of Jaxartes, at the Syr Darya river. Later on, Alexander himself used mounted archers recruited among the Scythians and Dahae, during the Greek invasion of India.
