History of the Peloponnesian War

The bulk of the inhabitants, upon hearing this, began to change their minds, especially as only a small number of the citizens were Athenians, the majority having come from different quarters, and many of the prisoners outside had relations within the walls. They found the proclamation a fair one in comparison of what their fear had suggested; the Athenians being glad to go out, as they thought they ran more risk than the rest, and further, did not expect any speedy relief, and the multitude generally being content at being left in possession of their civic rights, and at such an unexpected reprieve from danger.

The partisans of Brasidas now openly advocated this course, seeing that the feeling of the people had changed, and that they no longer gave ear to the Athenian general present; and thus the surrender was made and Brasidas was admitted by them on the terms of his proclamation.

In this way they gave up the city, and late in the same day Thucydides and his ships entered the harbour of Eion,

Brasidas having just got hold of Amphipolis, and having been within a night of taking Eion had the ships been less prompt in relieving it, in the morning it would have been his.
