Agis was not aware that the Argive generals had taken up a new position, and thinking that the confederates were still stationed on the hill, he gave up his scheme of diverting the water, and directed his march towards the place where he had first encamped. As they proceeded thus in marching order, and quite unprepared for any hostile movement, the Spartans suddenly found themselves face to face with the whole Argive army, drawn up in order of battle. For one instant it seemed as if a panic were about to spread through the Spartan ranks; then their wonderful discipline prevailed, and with all promptitude, but without flurry or confusion, the necessary orders were passed from the King to the commanders of divisions, from these again to the colonels, from the colonels to the captains, and from the captains down to the sergeants, [Footnote: I have thought it best to give the English titles, which of course have only a general correspondence with the Greek Polemarch, Lochagus, etc.] who in their turn had to see that the required movement was executed by the men under their command: for such was the regular gradation of authority and responsibility in the Spartan army. Thanks to this perfect organization, in a very few minutes every man was in his place and ready for battle. On the left wing of the Spartan army were posted the Sciritae, hardy mountaineers from southern Arcadia; next to them stood the enfranchised Helots, who had served under Brasidas in Thrace, and others of the same race who had received the Spartan citizenship in reward for public service; then came the main body of the Spartans themselves, and after them the rest of the Arcadian allies; while the right wing was assigned by immemorial privilege to the Tegeans, with whom were a few picked Spartans. The cavalry, never a very strong part of the Spartan army, were posted on either flank. On the other side the Mantineans held the place of honour on the right wing, because the engagement was fought in their territory; next in order were the Arcadian allies of Argos, and after them, more towards the centre, stood a picked troop of a thousand Argives, trained and equipped at the public expense; then followed the main body of the Argive troops, with the rest of their allies, the Athenians occupying the extreme left. As to the numbers engaged, nothing certain is known.
