History of the Peloponnesian War

Such was the plot which was then under way. It was the purpose of Hippocrates, when the proper moment should arrive, to take troops from Athens and in person make an expedition into Boeotia; meanwhile he was sending Demosthenes in advance with a fleet of forty ships to Naupactus, in order that he should first collect in this region an army of Acarnanians and of other allies of Athens and then sail to Siphae, in expectation of its being betrayed; and a day was agreed upon between the two generals for doing these two things simultaneously.

Upon his arrival at Naupactus, Demosthenes found that Oeniadae had already been forced by all the rest of the Acarnanians to join the Athenian alliance; he himself then raised all the allied forces in that district, and after first making an expedition against Salynthius and the Agraeans[*](cf. 3.111.4; 3.114.2.) and securing these, proceeded with his other preparations so as to be present at Siphae when needed.
