And the Athenian generals contributed no small share to such a result—that the pretext seemed strictly true, and its contrivers took it in hand more securely—by showing that they would not wish the men to be conveyed to Athens by another party, (they themselves being bound for Sicily,) and so to confer the honour on those who took them there.

When the Corcyraeans had got possession of them, they shut them up in a large building, and afterwards taking them out by twenties, led them through two rows of heavy-armed soldiers posted on each side; the prisoners being bound together, and beaten and stabbed by the men ranged in the lines, wherever any of them happened to see a personal enemy; while men carrying whips went by their side, and hastened on the way those that were proceeding too slowly.

As many as sixty men they took out in this manner, and put to death without the knowledge of those in the building; (for they supposed that they were taking them to be removed to some other place); but when they were aware of it, through some one's having pointed it out to them, they called on the Athenians, and desired that they would themselves put them to death, if they wished.
