History of the Peloponnesian War

The Athenians would not let any of them go, but themselves called for heralds from the mainland, and after questions had been carried backwards and forwards two or three times, the last man that passed over from the Lacedaemonians on the continent brought this message: ‘The Lacedaemonians bid you to decide for yourselves so long as you do nothing dishonourable;’ upon which after consulting together they surrendered themselves and their arms.

The Athenians, after guarding them that day and night, the next morning set up a trophy in the island, and got ready to sail, giving their prisoners in batches to be guarded by the captains of the galleys; and the Lacedaemonians sent a herald and took up their dead.
