History of the Peloponnesian War

Next to these were placed the Brasideian soldiers lately come out of Thrace, and with them those that had been newly made free. After them in order the rest of the Lacedaemonians, band after band; and by them Arcadians, first the Heraeans, after these the Maenalians. In the right wing were the Tegeats, and a few Lacedaemonians in the point of the same wing. And upon the outside of either wing, the horsemen.

So stood the Lacedaemonians. Opposite to them, in the right wing, stood the Mantineans, because it was upon their own territory; and with them such Arcadians as were of their league. Then the thousand chosen Argives, which the city had for a long time caused to be trained for the wars at the public charge, and next to them the rest of the Argives. After these, the Cleonaeans and Orneates, their confederates. And lastly, the Athenians, with the horsemen (which were also theirs) had the left wing.
