History of the Peloponnesian War

But Demosthenes was persuaded at the same time by the Messenians that it was a fine opportunity for him, with so large an army collected together, to attack the Aetolians, who were hostile to Naupactus, and by reducing whom he would easily win for Athens the rest of the continent in these parts.

For they represented to him that the nation of the Aetolians, though numerous and warlike, were yet not difficult to subdue before succours reached them, as they lived in unfortified villages, and those far apart, and used but light armour.

And they advised him to attack in the first place the Apodotians, next the Ophioneans, and after them the Eurytanians, which are the largest division of the nation, speaking, it is said, the most unintelligible language, and being cannibals; for if these were subdued, the rest would readily surrender.
