When Mardonius made a second incursion into the country of Attica, the people passed over again into the isle of Salamis. Aristides himself went to Lacedaemon, and reproved them for the delay and neglect in abandoning Athens once more to the barbarians; and demanded their assistance for that part of Greece which was not yet lost. The Ephori, hearing this, made show of sporting all day, and of carelessly keeping holy day (for they were then celebrating the Hyacinthian festival), but in the night, selecting five thousand Spartans, each of whom was attended by seven Helots, they sent them forth unknown to those from Athens. And when Aristides again reprehended them, they told him in derision that he either doted or dreamed, for the army was already at Oresteum, in their march towards the strangers; as they called the Persians. Aristides answered that they jested unreasonably, deluding their friends, instead of their enemies. Being chosen general for the war, he repaired to Plataea, with eight thousand Athenians, where Pausanias, generalissimo of all Greece, joined him with the Spartans; and the forces of the other Greeks came in to them. The encampment of the barbarians extended all along the bank of the river Asopus, their numbers being so great, there was no enclosing them all, but their baggage and most valuable things were surrounded with a square bulwark, each side of which was the length of ten furlongs. The Tegeatans, contesting the post of honor with the Athenians, demanded, that according to custom, the Lacedaemonians being ranged on the right wing of the battle, they might have the left, alleging several matters in commendation of their ancestors. The Athenians being indignant at the claim, Aristides came forward and said: "To contend with the Tegeatans for noble descent and valor, the present time permits not: but this we say to you, O you Spartans, and you the rest of the Greeks, that place neither takes away nor contributes courage: we shall endeavor by maintaining the post you assign us, to reflect no dishonor on our former performances. For we are come, not to differ with our friends, but to fight our enemies; not to extol our ancestors, but to behave as valiant men. This battle will manifest how much each city, captain, and private soldier is worth to Greece." The council of war, upon this address, decided for the Athenians, and gave them the other wing of the battle.
