Alexander’s army was marshalled as follows: The right wing was held by the cavalry Companions, in front of whom had been posted the royal squadron, commanded by Clitus, son of Dropidas. Near this was the squadron of Glaucias, next to it that of Aristo, then that of Sopolis, son of Hermodorus, then that of Heraclides, son of Antiochus. Near this was that of Demetrius, son of Althaemenes, then that of Meleager, and last one of the royal squadrons commanded by Hegelochus, son of Hippostratus. All the cavalry Companions were under the supreme command of Philotas, son of Parmenio. Of the phalanx of Macedonian infantry, nearest to the cavalry had been posted first the select corps of shield-bearing guards, and then the rest of the shield-bearing-guards, under the command of Nicanor, son of Parmenio. Next to these was the brigade of Coenus, son of Polemocrates; after these that of Perdiceas, son of Orontes, then that of Meleager, son of Neoptolemus, then that of Polysperchon,[408] son of Simmias, and last that of Amyntas, son of Andromenes, under the command of Simmias, because Amyntas had been despatched to Macedonia to levy an army. The brigade of Craterus, son of Alexander, held the left end of the Macedonian phalanx, and this general commanded the left wing of the infantry.[409] Next to him was the allied Grecian cavalry, under the command of Erigyius, son of Larichus. Next to these, towards the left wing of the army, were the Thessalian cavalry, under the command of Philip, son of Menelaüs. But the whole left wing was led by Parmenio, son of Philotas, round whose person were ranged the Pharsalian horsemen, who were both the best and most numerous squadron of the Thessalian cavalry.
