The passage of Brasidas was a complete surprise to the people in the town; and the capture of many of those outside, and the flight of the rest within the wall, combined to produce great confusion among the citizens; especially as they did not trust one another. It is even said that if Brasidas, instead of stopping to pillage, had advanced straight against the town, he would probably have taken it. In fact, however, he established himself where he was and overran the country outside, and for the present remained inactive, vainly awaiting a demonstration on the part of his friends within. Meanwhile the party opposed to the traitors proved numerous enough to prevent the gates being immediately thrown open, and in concert with Eucles, the general, who had come from Athens to defend the place, sent to the other commander in Thrace, Thucydides, son of Olorus, the author of this history, who was at the isle of Thasos, a Parian colony, half a day's sail from Amphipolis, to tell him to come to their relief. On receipt of this message he at once set sail with seven ships which he had with him, in order, if possible, to reach Amphipolis in time to prevent its capitulation, or in any case to save Eion.
