History of the Peloponnesian War

The Acarnanians, finding that a large army had invaded them by land, and that the enemy would also be upon them with a fleet by sea, did not prepare to make any united resistance, but to defend their own separate possessions; while they sent to Phormio, and desired him to succour them; who, however, said that it was impossible for him to leave Naupactus unprotected, while a fleet was on the point of sailing out from Corinth.
