History of the Peloponnesian War

Meanwhile, Brasidas, fearing the arrival of the ships from Thasos, and hearing that Thucydides possessed the right of working the gold-mines in that part of Thrace and in consequence had influence among the first men of the mainland, made haste to seize the city if possible before he should come; for he was afraid that, if Thucydides should arrive, the popular party in Amphipolis, in the expectation that he would collect an allied force from the islands and from Thrace and relieve them, would refuse to yield.

Accordingly, he offered moderate terms, making proclamation to this effect, that any citizen of Amphipolis or any resident Athenian, if he chose, might remain there, retaining possession of his own property and enjoying full equality; but that anyone who was not inclined to stay might go away within five days and take his property with him.
