History of the Peloponnesian War

Agis afraid of his left being surrounded, and thinking that the Mantineans outflanked it too far, ordered the Sciritae and Brasideans to move out from their place in the ranks and make the line even with the Mantineans, and told the Polemarchs Hipponoidas and Aristocles to fill up the gap thus formed, by throwing themselves into it with two companies taken from the right wing; thinking that his right would still be strong enough and to spare, and that the line fronting the Mantineans would gain in solidity.

However, as he gave these orders in the moment of the onset, and at short notice, it so happened that Aristocles and Hipponoidas would not move over, for which offence they were afterwards banished from Sparta, as having been guilty of cowardice; and the enemy meanwhile closed before the Sciritae (whom Agis on seeing that the two companies did not move over ordered to return to their place) had time to fill up the breach in question.

Now it was, however, that the Lacedaemonians, utterly worsted in respect of skill, showed themselves as superior in point of courage.

As soon as they came to close quarters with the enemy, the Mantinean right broke their Sciritae and Brasideans, and bursting in with their allies and the thousand picked Argives into the unclosed breach in their line cut up and surrounded the Lacedaemonians, and drove them in full rout to the wagons, slaying some of the older men on guard there.

But the Lacedaemonians, worsted in this part of the field, with the rest of their army, and especially the center, where the three hundred knights, as they are called, fought round King Agis, fell on the older men of the Argives and the five companies so named, and on the Cleonaeans, the Orneans, and the Athenians next them, and instantly routed them; the greater number not even waiting to strike a blow, but giving way the moment that they came on, some even being trodden under foot, in their fear of being overtaken by their assailants.

The army of the Argives and their allies having given way in this quarter was now completely cut in two, and the Lacedaemonian and Tegean right simultaneously closing round the Athenians with the troops that outflanked them, these last found themselves placed between two fires, being surrounded on one side and already defeated on the other. Indeed they would have suffered more severely than any other part of the army, but for the services of the cavalry which they had with them.
