History of the Peloponnesian War

For it was not, I think, because of their unlawfully inhabiting this spot, that such misfortunes befell the city; but it was owing to the war that the necessity of inhabiting it arose; which war though the god did not mention, he foreknew that [owing to it] the Pelasgium would hereafter be inhabited for no good.

Many, too, quartered themselves in the towers of the walls, and in whatever way each could: for the city did not hold them when they were come all together; but subsequently they occupied the long walls, partitioning them out amongst them, and the greater part of the Piraeus.

At the same time they also applied themselves to matters connected with the war; mustering their allies, and equipping an armament of a hundred ships for the Peloponnese.

The Athenians then were in this state of preparation.

As for the army of the Peloponnesians, on the other hand, the first town it came to in Attica was Oenoe, at which point they intended to make their inroad.
