Now these Locrians called Ozolae were confederates of the Athenians and were to meet them with their whole power in the heart of the country. For being confiners on the Aetolians and using the same manner of arming, it was thought it would be a matter of great utility in the war to have them in their army for that they knew their manner of fight and were acquainted with the country.

Having lain the night with his whole army in the temple of Jupiter Nemeius (wherein the poet Hesiodus is reported by them that dwell thereabout to have died, foretold by an oracle that he should die in Nemea), in the morning betimes he dislodged and marched into Aetolia.

The first day he took Potidania; the second day, Crocyleium; the third, Teichium. There he stayed and sent the booty he had gotten to Eupalium in Locris. For he purposed, when he had subdued the rest, to invade the Ophionians afterwards (if they submitted not) in his return to Naupactus.

But the Aetolians knew of this preparation when it was first resolved on. And afterwards, when the army was entered, they were united into a mighty army to make head, insomuch as that the farthest off of the Ophionians that reach out to the Melian Gulf, the Bomians and Callians, came in with their aids.
