History of the Peloponnesian War

In the mean time Brasidas, being afraid of the naval succour from Thasos, and hearing that Thucydides possessed the right of working the gold mines in those parts of Thrace, and by this means had influence amongst the chief persons on the mainland, made haste to get possession of the town beforehand, if possible; lest, if he came, the populace of Amphipolis, hoping that he would raise a confederate force from the sea and from Thrace, and so save them, should not then surrender to him.

Accordingly he was willing to come to moderate terms with them, and made this proclamation; that of the Amphipolitans and Athenians in the town whoever would might remain in possession of his property, sharing in a fair and equal government; and whoever would not, might depart and take out his property with him, within five days.
