History of the Peloponnesian War

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.

When he had accomplished this, he was about to sail away; but the leaders of the people persuaded him to leave them five of his ships, that their opponents might be somewhat less inclined to disturbance, agreeing on their part to man and send with him an equal number of their own ships.

He agreed, and they began to tell off their personal enemies as crews for the ships. But these, fearing that they might be sent off to Athens, sat down as suppliants in the temple of the Dioscuri.
