History of the Peloponnesian War

In the meantime, the Samians, coming suddenly forth with their fleet and falling upon the harbour of the Athenians which was unfortified, sunk the galleys that kept watch before it and overcame the rest in fight, insomuch that they became masters of the sea near their coast for about fourteen days together, importing and exporting what they pleased.

But Pericles returning shut them up again with his galleys. And after this there came to him from Athens a supply of forty sail, with Thucydides, Agnon, and Phormio; and twenty with Tlepolemus and Anticles; and from Chios and Lesbos thirty more.

And though the Samians fought against these a small battle at sea, yet unable to hold out any longer, in the ninth month of the siege they rendered the city upon composition: namely, to demolish their walls, to give hostages, to deliver up their navy, and to repay the money spent by the Athenians in the war at days appointed. And the Byzantines also yielded with condition to remain subject to them in the same manner as they had been before their revolt.
