History of the Peloponnesian War

At the close of the summer, the Athenians at Naupactus and the Acarnanians made an expedition, and took Anactorium, a city belonging to the Corinthians, which is situated at the mouth of the Ambracian Gulf, and was betrayed to them. And having turned out the Corinthians, Acarnanian settlers from all parts of the country themselves kept possession of the place. And so the summer ended.

The following winter Aristides son of Archippus, a commander of the Athenian ships which had been sent out to the allies to levy contributions, arrested at Eion on the Strymon Artaphernes, a Persian, on his way from the king to Lacedaemon.

On his being conveyed to Athens, they got his despatches translated out of the Assyrian character, and read them: the substance of which, as regarded the Lacedaemonians, (though many other things were mentioned in them,) was, that the king did not understand what they would have; for though many ambassadors had come to him, no one ever made the same statement as another; if then they would but speak plainly, they might send men to him in company with this Persian.
