History of the Peloponnesian War

To some few of those in the island they secretly send their friends and instruct them to say, as if forsooth it were for good will, that it was their best course with all speed to get away; and withal, to offer to provide them of a boat; for that the Athenian commanders intended verily to deliver them to the Corcyraean people.

When they were persuaded to do so and that a boat was treacherously prepared, as they rowed away they were taken; and the truce being now broken, were all given up into the hands of the Corcyraeans.
