History of the Peloponnesian War

Meanwhile Brasidas, afraid of succors arriving by sea from Thasos, and learning that Thucydides possessed the right of working the gold mines in that part of Thrace, and had thus great influence with the inhabitants of the continent, hastened to gain the town, if possible, before the people of Amphipolis should be encouraged by his arrival to hope that he could save them by getting together a force of allies from the sea and from Thrace, and so refuse to surrender.

He accordingly offered moderate terms, proclaiming that any of the Amphipolitans and Athenians who chose, might continue to enjoy their property with full rights of citizenship; while those who did not wish to stay had five days to depart, taking their property with them.

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.
