History of the Peloponnesian War

When, however, after assaulting Oenoe and trying in every way to take it they were not able to do so, the Athenians meanwhile making no overtures, then at length they set off from there, about eighty days after the events at Plataea, when it was midsummer[*](The reference is to the Attic summer, which included spring. The date was about the end of May, the average time for cutting grain in Attica.) and the corn was ripe, and invaded Attica, under the command of Arehidamus son of Zeuxidamus, king of the Lacedaemonians.

Making a halt they proceeded to ravage, first of all, the territory of Eleusis and the Thriasian plain, and they routed the Athenian cavalry near the streams called Rheiti; then they advanced, keeping Mount Aegaleos on their right through Cropia,[*](A deme between Aegaleos and Parnes.) until they came to Acharnae, the largest of the demes of Attica, as they are called. Halting in the town they made a camp, where they remained for a long time ravaging the country.
