Both sides were now arming, and there was the unmistakeable signs of approaching battle, when, as the first incident, there issued from the Boeotian lines a long train bent on departure--these were the furnishers of the market, a detachment of baggage bearers, and in general such people as had no inclination to join in the fight. These were met on their retreat and attacked by the mercenary troops under Hiero, who got round them by a circular movement. (8) The mercenaries were supported by the Phocian light infantry and some squadrons of Heracleot and Phliasian cavalry, who fell upon the retiring train and turned them back, pursuing them and driving them into the camp of the Boeotians. The immediate effect was to make the Boeotian portion of the army more numerous and closer packed than before. The next feature of the combat was that in consequence of the flat space of plain (9) between the opposing armies, the Lacedaemonians posted their cavalry in front of their squares of infantry, and the Thebans followed suit. Only there was this difference--the Theban cavalry was in a high state of training and efficiency, owing to their war with the Orchomenians and again their war with Thespiae, whilst the cavalry of the Lacedaemonians was at its worst at this period. (10) The horses were reared and kept by the wealthiest members of the state; but whenever the ban was called out, an appointed trooper appeared who took the horse with any sort of arms which might be presented to him, and set off on the expedition at a moment's notice. Moreover, these troopers were the least able-bodied of the men: raw recruits set simply astride their horses, and devoid of soldierly ambition. Such was the cavalry of either antagonist. (8) Or, "surrounded them." (9) See Rustow and Kochly, op. cit. p. 173. (10) See "Hipparch." ix. 4; also "Cyrop." VIII. viii. The heavy infantry of the Lacedaemonians, it is said, advanced by sections three files abreast, (11) allowing a total depth to the whole line of not more than twelve. The Thebans were formed in close order of not less than fifty shields deep, calculating that victory gained over the king's division of the army implied the easy conquest of the rest. (11) It would appear that the "enomoty" (section) numbered thirty-six files. See "Pol. Lac." xi. 4; xiii. 4. For further details as to the tactical order of the Thebans, see Diod. xv. 55; Plut. "Pelop." xxiii.
