History of the Peloponnesian War

Whereupon, after they had plied the Athenians and their confederates all day long from every side with shot and saw that with their wounds and other annoyance they were already tired, Gylippus and the Syracusians and their confederates first made proclamation that if any of the islanders would come over to them, they should be at liberty. And the men of some few cities went over.

And by and by after, they made agreement with all the rest that were with Demosthenes that they should deliver up their arms, and none of them be put to death, neither violently, nor by bonds, nor by want of the necessities of life.

And they all yielded, to the number of six thousand men; and the silver they had, they laid it all down, casting it into the hollow of targets, and filled with the same four targets. And these men they carried presently into the city. Nicias, and those that were with him, attained the same day to the river Erineus, which passing, he caused his army to sit down upon a certain ground more elevate than the rest.

Where the Syracusians the next day overtook and told him, that those with Demosthenes had yielded themselves, and willed him to do the like. But he, not believing it, took truce for a horseman to enquire the truth.

Upon return of the horseman and word that they had yielded, he sent a herald to Gylippus and the Syracusians, saying that he was content to compound on the part of the Athenians to repay whatsoever money the Syracusians had laid out, so that his army might be suffered to depart, and that till payment of the money were made, he would deliver them hostages, Athenians, every hostage rated as a talent.
