History of the Peloponnesian War

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.

Agis also on perceiving the distress of his left opposed to the Mantineans and the thousand Argives, ordered all the army to advance to the support of the defeated wing;

and while this took place, as the enemy moved past and slanted away from them, the Athenians escaped at their leisure, and with them the beaten Argive division. Meanwhile the Mantineans and their allies and the picked body of the Argives ceased to press the enemy, and seeing their friends defeated and the Lacedaemonians in full advance upon them, took to flight.

Many of the Mantineans perished; but the bulk of the picked body of the Argives made good their escape. The flight and retreat, however, were neither hurried nor long; the Lacedaemonians fighting long and stubbornly until the rout of their enemy, but that once effected, pursuing for a short time and not far.
