History of the Peloponnesian War

For the Athenians during this time were carrying in their property, and the Peloponnesians thought that by advancing against them quickly they would have found every thing still out, but for his dilatoriness.

Such resentment did the army feel towards Archidamus during the siege. But he, it is said, was waiting in expectation that the Athenians would give in, while their land was still unravaged, and would shrink from enduring to see it wasted.

When, however, after assaulting Oenoe, and trying every method, they were unable to take the place, and the Athenians sent no herald to them, then indeed they set out from before it, and about eighty days after the events at Plataea, caused by the Thebans who had entered it, when the summer was at its height, and the corn ripe, they made their incursion into Attica; Archidamus son of Zeuxidamus, king of the Lacedaemonians, being their commander.
