XVI. At this time, Herodotus tells us, Pausanias asked Aristeides to remove the Athenians from the left to the right wing, so as to be opposite to the native Persian troops, on the ground that they would be better able to contend with them, because they understood their mode of fighting, and were confident because they had beaten them once before, while he with the Spartans would take the left wing of the army, where he would be opposed to those Greeks who had taken the Persian side. Most of the Athenian generals thought this a silly and insolent proceeding of Pausanias, that he should leave all the other Greeks in their place, and march them backwards and forward like helots, only to place them opposite the bravest troops of the enemy. Aristeides, however, said that they were entirely mistaken, for a few days before they had been wrangling with the Tegeans for the honour of being posted on the left wing, and had been delighted when they obtained it; but now, when the Lacedæmonians of their own free will yielded the right wing to them, and in some sort offered them the post of honour in the whole army, they were not delighted at it, and did not consider what an advantage it was to have to fight against foreign barbarians, and not against men of their own race and nation. After these words, the Athenians cheerfully exchanged places with the Lacedæmonians, and much talk went on among them as each man reminded his comrades that the Persians who would come to attack them were no braver, nor better armed than those whom they had defeated at Marathon, but that they had the same bows and arrows, the same embroidered robes and gold ornaments on their effeminate bodies, while we, they said, have arms and bodies such as we had then, and greater confidence because of our victories. We also fight, not merely as other Greeks do, in defence of our city and territory, but for the trophies of Marathon and Salamis, lest the battle of Marathon should be thought to have been won more by Miltiades and Fortune, than by the valour of the Athenians. With such encouraging talk as this the Athenians took up their new position; but the Thebans discovered what had been done from deserters and told Mardonius. He at once, either from fear of the Athenians, or from a chivalrous wish to fight the Spartans himself, led the native Persian troops to his right wing, and ordered the renegade Greeks to take ground opposite the Athenians. When these changes were being observed, Pausanias returned to his original position on the right. Mardonius then returned to the left as before, and the day passed without an engagement. The Greeks now determined in a council of war, to remove their camp to a place farther away and better supplied with water, because they were prevented from using the springs near where they were by the enemy's great superiority in cavalry.
