The Spartans began their compliance by forthwith releasing all the Athenian prisoners in their hands, and despatching Ischagoras with two other envoys to Amphipolis and the Thracian towns. These envoys were directed to proclaim the peace as well as to enforce its observance upon the Thracian towns, and especially to command Klearidas, the Spartan commander in Amphipolis, that he should surrender the town to the Athenians. But on arriving in Thrace, these envoys met with nothing but unanimous opposition: and so energetic were the remonstrances of the Chalkidians, both in Amphipolis and out of it, that even Klearidas refused obedience to his own government, pretending that he was not strong enough to surrender the place against the resistance of the Chalkidians. Thus completely baffled, the envoys returned to Sparta, whither Klearidas thought it prudent to accompany them, partly to explain his own conduct, partly in hopes of being able to procure some modification of the terms. But he found this impossible, and he was sent back to Amphipolis with peremptory orders to surrender the place to the Athenians, if it could possibly be done; if that should prove beyond his force, then to come away, and bring home every Peloponnesian soldier in the garrison. Perhaps the surrender was really impracticable to a force no greater than that which Klearidas commanded, since the reluctance of the population was doubtless obstinate. At any rate, he represented it to be impracticable: the troops accordingly came home, but the Athenians still remained excluded from Amphipolis, and all the stipulations of the peace respecting the Thracian towns remained unperformed. Nor was this all. The envoys from the recusant minority (Corinthians and others), after having gone home for instructions, had now come back to Sparta with increased repugnance and protest against the injustice of the peace, so that all the efforts of the Spartans to bring them to compliance were fruitless.[5] [5] Thucyd. v, 21, 22.
