The barbarian army having ceased to lament Masistius, as soon as they knew that the Greeks were advanced to Platæa, marched also to that part of the Asopus nearest to it; where they were thus disposed by Mardonius. Opposed to the Lacedæmonians were the Persians, who, as they were superior in number, fronted the Tegeatæ also. Of this body the select part was opposed to the Lacedæmonians, the less effective to the Tegeatæ. In making which arrangement, Mardonius followed the advice of the Thebans. Next to the Persians were the Medes, opposed to the Corinthians, Potidæans, Orchomenians, and Sicyonians. The Bactrians were placed next, to encounter the Epidaurians, Trœzenians, Lepreatæ, Tirynthians, Mycenæans, and Phliasians. Contiguous to the Bactrians the Indians were disposed, in opposition to the Hermionians, Eretrians, Styrians, and Chalcidians. The Sacæ, next in order, fronted the Ambracians, Anactorians, Leucadians, Paleans, and Æginetæ. The Athenians, Platæans, and Megarians were ultimately faced by the Bœotians, Locrians, Melians, Thessalians, and a thousand Phocians. All the Phocians did not assist the Medes; some of them, about Parnassus, favoured the Greeks, and from that station attacked and harassed both the troops of Mardonius and those of the Greeks who were with him. The Macedonians and Thessalians were also opposed to the Athenians.
In this manner Mardonius arranged those nations who were the most numerous and the most illustrious; with these were promiscuously mixed bodies of Phrygians, Thracians, Mysians, Pæonians, and others. To the above might be added the Ethiopians, and those Egyptians named Hermotybians and Calasirians, who alone of that country follow the profession of arms. These had formerly served on board the fleet, whence they had been removed to the land-forces by Mardonius when at Phalerum: the Egyptians had not been reckoned with those forces which Xerxes led against Athens. We have before remarked, that the barbarian army consisted of three hundred thousand men; the number of the Greek confederates of Mardonius, as it was never taken, cannot be ascertained; but as far as conjecture may determine, they amounted to about fifty thousand men. Such was the arrangement of the infantry; the cavalry were posted apart by themselves.
Both armies being thus ranged in nations and squadrons, on the following day offered sacrifices. The sacrifices promised victory to the Greeks if they acted on the defensive, but the contrary if, passing the Asopus, they began the fight. Mardonius, though anxious to engage, had nothing to hope from the entrails, unless he acted on the defensive only. He had also sacrificed according to the Grecian rites, using as his soothsayer Hegesistratus, an Elean, and the most illustrious of the Telliadæ. The Spartans had formerly seized this man, thrown him into prison, and menaced him with death, as one from whom they had received many and atrocious injuries. In this distress, alarmed not merely for his life, but with the idea of having previously to suffer many severities, he accomplished a thing which can hardly be told. He was confined in some stocks bound with iron, but accidentally obtaining a knife, he perpetrated the boldest thing which has ever been recorded.
Calculating what part of the remainder he should be able to draw out, he cut off the extremity of his foot; this done, notwithstanding he was guarded, he dug a hole under the wall, and escaped to Tegea, travelling only by night, and concealing himself in the woods during the day. Eluding the strictest search of the Lacedæmonians, he came on the third night to Tegea, his keepers being astonished at his resolution, for they saw the half of his foot, but could not find the man. In this manner Hegesistratus escaped to Tegea, which was not at that period in amity with Sparta. When his wound was healed he procured himself a wooden foot, and became an avowed enemy to Sparta. His animosity against the Lacedæmonians proved ultimately of no advantage to himself; he was taken in the exercise of his office at Zacynthus, and put to death. The fate of Hegesistratus was subsequent to the battle of Platæa: at the time of which we were speaking, Mardonius, for a considerable sum, had prevailed with him to sacrifice, which he eagerly did, as well from his hatred of the Lacedæmonians, as from the desire of reward; but the appearance of the entrails gave no encouragement to fight, either to the Persians or their confederate Greeks, who also had their own appropriate soothsayer, Hippomachus of Leucadia. As the Grecian army continually increased, Timagenidas of Thebes, son of Herpys, advised Mardonius to guard the pass of Cithæron, representing that he might thus intercept great bodies, who were every day thronging to the allied army of the Greeks.
The hostile armies had already remained eight days encamped opposite to each other, when the above counsel was given to Mardonius. He acknowledged its propriety, and immediately on the approach of night detached some cavalry to that part of Cithæron leading to Platæa, a place called by the Bœotians the “Three Heads,” by the Athenians the “Heads of Oak.” This measure had its effect, and they took a convoy of five hundred beasts of burden, carrying a supply of provisions from the Peloponnesus to the army: with the carriages, they took also all the men who conducted them. Masters of this booty, the Persians, with the most unrelenting barbarity, put both men and beasts to death: when their cruelty was satiated, they returned with what they had taken to Mardonius.
After this event two days more passed, neither army being willing to engage. The barbarians, to irritate the Greeks, advanced as far as the Asopus, but neither army would pass the stream. The cavalry of Mardonius greatly and constantly harassed the Greeks. The Thebans, who were very zealous in their attachment to the Medes, prosecuted the war with ardour, and did everything but join battle; the Persians and Medes supported them and performed many illustrious actions.
In this situation things remained for the space of ten days: on the eleventh, the armies retaining the same position with respect to each other, and the Greeks having received considerable reinforcements, Mardonius became disgusted with their inactivity. He accordingly held a conference with Artabazus, the son of Pharnaces, who was one of the few Persians whom Xerxes honoured with his esteem: it was the opinion of Artabazus that they should immediately break up their camp, and withdraw beneath the walls of Thebes, where was already prepared a magazine of provisions for themselves, and corn for their cavalry: here they might at their leisure terminate the war by the following measures. They had in their possession a great quantity of coined and uncoined gold, with an abundance of silver and plate: it was recommended to send these with no sparing hand to the Greeks, and particularly to those of greatest authority in their respective cities. It was urged, that if this were done, the Greeks would soon surrender their liberties, nor again risk the hazard of a battle. This opinion was seconded by the Thebans, who thought that it would operate successfully. Mardonius was of a contrary opinion, fierce, obstinate, and unyielding. His own army he thought superior to that of the Greeks, and that they should by all means fight before the Greeks received further supplies; that they should give no importance to the declarations of Hegesistratus, but without violating the laws of Persia, commence a battle in their usual manner. This opinion of Mardonius nobody thought proper to oppose, for to him, and not to Artabazus, the king had confided the supreme command of the army. He therefore ordered that everything should be properly disposed to commence the attack early in the morning.
When the night was far advanced, and the strictest silence prevailed through the army, which was buried in sleep, Alexander, son of Amyntas, general and prince of the Macedonians, rode up to the Athenian outposts, and earnestly desired to speak with their commanders. On hearing this, the greater number continued on their posts, while some hastened to their officers, whom they informed that a horseman was arrived from the enemy’s army, who, naming the principal Greeks, would say nothing more than that he desired to speak with them.
