History of the Peloponnesian War

And during the night, after they had desisted from battle, both parties rested but remained on the alert; and now that the people had got the upper hand the Corinthian ship slipped out to sea, and most of the mercenaries were secretly conveyed over to the mainland.

On the following day Nicostratus son of Diitrephes, general of the Athenians, came to their assistance from Naupactus with twelve ships and five hundred Messenian hoplites. He tried to negotiate a settlement between the factions, and succeeded in persuading them to come to a mutual agreement: that the twelve men who were chiefly to blame should be brought to trial (whereupon they fled at once) and that the rest should make peace with each other and dwell together, and enter into an offensive and defensive alliance with the Athenians.
