After this skirmish of the horse, they kept from fighting a long time; for the soothsayers, by the sacrifices, foretold the victory both to Greeks and Persians, if they stood upon the defensive part only, but if they became aggressors, the contrary. At length Mardonius, when he had but a few days' provision, and the Greek forces increased continually by some or other that came in to them, impatient of delay, determined to lie still no longer, but passing Asopus by daybreak, to fall unexpectedly upon the Greeks; and signified the same over night to the captains of his host. But about midnight, a certain horseman stole into the Greek camp, and coming to the watch, desired them to call Aristides, the Athenian, to him. He coming speedily, "I am," said the stranger, "Alexander, king of the Macedonians, and am arrived here through the greatest danger in the world for the goodwill I bear you, lest a sudden onset should dismay you, so as to behave in the fight worse than usual. For to-morrow Mardonius will give you battle, urged, not by any hope of success or courage, but by want of victuals; since, indeed, the prophets prohibit him the battle, the sacrifices and oracles being unfavourable; and the army is in despondency and consternation; but necessity forces him to try his fortune, or sit still and endure the last extremity of want." Alexander, thus saying, entreated Aristides to take notice and remember him, but not to tell any other. But he told him, it was not convenient to conceal the matter from Pausanias (because he was general); as for any other, he would keep it secret from them till the battle was fought; but if the Greeks obtained the victory, that then no one should be ignorant of Alexander's good-will and kindness towards them. After this, the king of the Macedonians rode back again, and Aristides went to Pausanias's tent and told him they sent for the rest of the captains and gave orders that the army should be in battle array.
Here, according to Herodotus, Pausanias spoke to Aristides, desiring him to transfer the Athenians to the right wing of the army opposite to the Persians (as they would do better service against them, having been experienced in their way of combat, and emboldened with former victories), and to give him the left, where the Medizing Greeks were to make their assault. The rest of the Athenian captains regarded this as an arrogant and interfering act on the part of Pausanias;because, while permitting the rest of the army to keep their stations, he removed them only from place to place, like so many Helots, opposing them to the greatest strength of the enemy. But Aristides said they were altogether in the wrong. If so short a time ago they contested the left wing with the Tegeatans, and gloried in being preferred before them, now, when the Lacedaemonians give them place in the right, and yield them in a manner the leading of the army, how is it they are discontented with the honour that is done them, and do not look upon it as an advantage to have to fight, not against their countrymen and kindred, but barbarians, and such as were by nature their enemies? After this, the Athenians very readily changed places with the Lacedaemonians, and there went words amongst them as they were encouraging each other that the enemy approached with no better arms or stouter hearts than those who fought the battle of Marathon; but had the same bows and arrows, and the same embroidered coats and gold, and the same delicate bodies and effeminate minds within; "While we have the same weapons and bodies, and our courage augmented by our victories; and fight not like others in defence of our country only, but for the trophies of Salamis and Marathon; that they may not be looked upon as due to Miltiades or fortune, but to the people of Athens." Thus, therefore, were they ****** haste to change the order of their battle. But the Thebans, understanding it by some deserters, forthwith acquainted Mardonius; and he, either for fear of the Athenians, or a desire to engage the Lacedaemonians, marched over his Persians to the other wing, and commanded the Greeks of his party to be posted opposite to the Athenians. But this change was observed on the other side, and Pausanias, wheeling about again, ranged himself on the right, and Mardonius, also, as at first, took the left wing over against the Lacedaemonians. So the day passed without action.
After this the Greeks determined in council to remove their camp some distance, to possess themselves of a place convenient for watering; because the springs near them were polluted and destroyed by the barbarian cavalry. But night being come, and the captains setting out towards the place designed for their camping, the soldiers were not very ready to follow, and keep in a body, but, as soon as they had quitted their first entrenchments, made towards the city of Plataea; and there was much tumult and disorder as they dispersed to various quarters and proceeded to pitch their tents. The Lacedaemonians, against their will, had the fortune to be left by the rest. For Amompharetus, a brave and daring man, who had long been burning with desire of the fight, and resented their many lingerings and delays, calling the removal of the camp a mere running away and flight, protested he would not desert his post, but would there remain with his company and sustain the charge of Mardonius. And when Pausanias came to him and told him he did do these things by the common vote and determination of the Greeks, Amompharetus taking up a great stone and flinging it at Pausanias'
feet, and "By this token," said he, "do I give my suffrage for the battle, nor have I any concern with the cowardly consultations and decrees of other men." Pausanias, not knowing what to do in the present juncture, sent to the Athenians, who were drawing off, to stay to accompany him; and so he himself set off with the rest of the army for Plataea, hoping thus to make Amompharetus move.
