The Macedonians were divided into two, with the right side under the direct command of Alexander and the left of Parmenion. Alexander fought with his Companion cavalry. With it was the Paionian and Greek light cavalry. The mercenary cavalry was divided into two groups, veterans on the flank of the right and the rest in front of the Agrians and Greek archers, who were stationed next to the phalanx. Parmenion was stationed on the left with the Thessalians, Greek mercenaries and Thracian cavalry. There they were to conduct a holding action while Alexander launched the decisive blow from the right.
