History of the Peloponnesian War

But after, when they had assaulted Oenoe and tried all means but could not take it, and seeing the Athenians sent no herald to them, then at length arising from thence—about eighty days after that which happened to the Thebans that entered Plataea, the summer and corn being now at the highest—they fell into Attica, led by Archidamus the son of Zeuxidamus, king of the Lacedaemonians.

And when they had pitched their camp, they fell to wasting of the country, first about Eleusis and then in the plain of Thriasia, and put to flight a few Athenian horsemen at the brooks called Rheiti. After this, leaving the Aegaleon on the right hand, they passed through Cecropia till they came unto Acharnas, which is the greatest town in all Attica of those that are called Demoi, and pitching there, both fortified their camp and stayed a great while wasting the country thereabout.
