The Aetolian nation, although numerous and warlike, yet dwelt in unwalled villages scattered far apart, and had nothing but light armour, and might, according to the Messenians, be subdued without much difficulty before succours could arrive.

The plan which they recommended was to attack first the Apodotians, next the Ophionians, and after these the Eurytanians, who are the largest tribe in Aetolia, and speak, as is said, a language exceedingly difficult to understand, and eat their flesh raw.

These once subdued, the rest would easily come in.
To this plan Demosthenes consented, not only to please the Messenians, but also in the belief that by adding the Aetolians to his other continental allies he would be able, without aid from home, to march against the Boeotians by way of Ozolian Locris to Kytinium in Doris, keeping Parnassus on his right until he descended to the Phocians, whom he could force to join him if their ancient friendship for Athens did not, as he anticipated, at once decide them to do so.

Arrived in Phocis he was already upon the frontier of Boeotia.

He accordingly weighed from Leucas, against the wish of the Acarnanians, and with his whole armament sailed along the coast to Sollium, where he communicated to them his intention; and upon their refusing to agree to it on account of the non-investment of Leucas, himself with the rest of the forces, the Cephallenians, the Messenians, and Zacynthians, and three hundred Athenian marines from his own ships (the fifteen Corcyraean vessels having departed), started on his expedition against the Aetolians.
