History of the Peloponnesian War

For when they came to close quarters with the foe, the right wing of the Mantineans routed, it is true, the Sciritae and the Brasideans, and then the Mantineans and their allies and the thousand picked men of the Argives, rushing into the gap that had not been closed, played havoc with the Lacedaemonians; for they surrounded and put them to rout, and drove them in among the wagons, slaying some of the older men stationed there.

In this quarter, then, the Lacedaemonians were worsted; but in the rest of the army, and especially in the centre, where King Agis was, and about him the three hundred who were called knights,[*](Chosen from the flower of the Spartan youth and serving as a royal body-guard, on foot as well as on horseback.) they fell upon the older men of the Argives, the so-called five companies, and upon the Cleonaeans, the Orneates, and those of the Athenians that were arrayed with them, and routed them. Most of the enemy did not even wait to come to blows, but when the Lacedaemonians came on gave way at once, some of them being trodden underfoot in their effort to get out of the way before being hemmed in by the Lacedaemonians.

When the army of the Argives and their allies had given way in this quarter, their line was on the point of being broken in both directions; and at the same time the right wing of the Lacedaemonians and the Tegeates was beginning to encircle the Athenians with the outflanking part of their own line; and so danger beset them on both sides, for they were being surrounded in one quarter and had been already defeated in the other.
