History of the Peloponnesian War

At last, when many dead now lay piled one upon another in the stream, and part of the army had been destroyed at the river, and the few that escaped from thence cut off by the cavalry, Nicias surrendered himself to Gylippus, whom he trusted more than he did the Syracusans, and told him and the Lacedaemonians to do what they liked with him, but to stop the slaughter of the soldiers.

Gylippus, after this, immediately gave orders to make prisoners; upon which the rest were brought together alive, except a large number secreted by the soldiery, and a party was sent in pursuit of the three hundred who had got through the guard during the night, and who were now taken with the rest.

The number of the enemy collected as public property was not considerable; but that secreted was very large, and all Sicily was filled with them, no convention having been made in their case as for those taken with Demosthenes.

Besides this, a large portion were killed outright, the carnage being very great, and not exceeded by any in this Sicilian war. In the numerous other encounters upon the march, not a few also had fallen. Nevertheless many escaped, some at the moment, others served as slaves, and then ran away subsequently. These found refuge at Catana.
