History of the Peloponnesian War

If any of the cities comprehended in the league made with the king shall invade the king's territories, the rest shall oppose them and defend the king to the utmost of their power. If any city of the king's, or under his dominion, shall invade the Lacedaemonians or their confederates, the king shall make opposition and defend them to the utmost of his power.

After this accord made, Theramenes delivered his galleys into the hands of Astyochus and, putting to sea in a light-horseman, is no more seen.
