History of the Peloponnesian War

And the Athenians being arrived in Sicily, whither they were at first bound, prosecuted the war there together with the rest of their confederates of those parts.

In the end of this summer, the Athenians that lay at Naupactus went forth with an army and took the city of Anactorium, belonging to the Corinthians and lying at the mouth of the Ambracian gulf, by treason. And when they had put forth the Corinthians, the Acarnanians held it with a colony sent thither from all parts of their own nation. And so this summer ended.

The next winter, Aristides, the son of Archippus, one of the commanders of a fleet which the Athenians had sent out to gather tribute from their confederates, apprehended Artaphernes, a Persian, in the town of Eion upon the river Strymon, going from the king to Lacedaemon.
