History of the Peloponnesian War

For in this time the Athenians retired into the city: whereas it was thought that the Peloponnesians, marching speedily, might but for this delay have taken them all without.

So passionate was the army of Archidamus for his stay before Oenoe. But expecting that the Athenians, whilst their territory was yet unhurt, would relent and not endure to see it wasted, for that cause (as it is reported) he held his hand.

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.
