Passage: According to Diodorus, the Macedonian army numbered roughly 30,000 infantry and 2,000 cavalry, a figure generally accepted by modern historians. Philip took command of the right wing of the Macedonian army and placed his 18-year-old son Alexander (the future conqueror of the Persian Empire) in command of the left wing, accompanied by a group of Philip's experienced generals.The allied army included contingents from Achaea, Corinth, Chalcis, Epidaurus, Megara, and Troezen, with the majority of troops being supplied by Athens and Thebes. The Athenian contingent was led by the generals Chares and Lysicles, and the Thebans by Theagenes. No source provides exact numbers for the allied army, although Justin suggests that the southern Greeks were "far superior in number of soldiers"; the modern view is that the numbers of the city states that fought were approximately equal to those of the Macedonians. The Athenians took up positions on the left wing, the Thebans on the right, and the other allies in the centre.Athenian aristocrat Philippides of Paiania, campaigned for Philip's cause with his associates during the battle in Thebes, Eleuthera and Tanagra. Philippides was later prosecuted by Hypereides for his pro-Macedonian actions after the defeat.
