The Aetolians (for they had now come to the rescue of Aegitium) charged the Athenians and their allies, running down from the hills in different directions, and plied them with darts; retreating when the Athenian force advanced against them, and pressing it close when it retired. And for a long time this was the character of the engagement—repeated pursuing and retreating—in both of which the Athenians had the worse.
