History of the Peloponnesian War

Now the Lacedaemonians (for it fell to their lot to be the first to restore what they held) immediately released the men who were prisoners in their country; and sending as ambassadors to the countries Thrace-ward, Ischagoras, Menas, and Philocharidas, commanded Clearidas to restore Amphipolis to the Athenians, and the rest of the states to accept the treaty, as it had been severally arranged for them.

They, however, would not, as they thought it not favourable to them; nor did Clearidas restore the city, wishing to oblige the Chalcidians, and declaring that he could not give it up in opposition to them.

He, however, went in haste to Lacedaemon with ambassadors from that place, to defend himself, if Ischagoras and his party should bring any charge against him for not obeying; and at the same time from a wish to know whether the arrangement might still be altered: but when he found the treaty secured, being sent back again himself by the Lacedaemonians, and ordered to deliver up the place, if possible, but if not, to bring out all the Peloponnesians that were in it, he set out with all speed.
