History of the Peloponnesian War

So they weighed anchor, and were cruising round with this armament; while the Peloponnesians, after staying in Attica the time for which they had provisions, retired through Boeotia, (not by the same way they had made their inroad,) and passing by Oropus ravaged the Piraic territory, as it is called, which the Oropians inhabit as subjects of the Athenians. On arriving at the Peloponnese, they were disbanded, and returned to their several cities.

When they had retired, the Athenians set guards by land and by sea, as they intended to keep them through the whole war. And they resolved to take out and set apart a thousand talents from the money in the Acropolis, and not to spend them, but to carry on the war with their other resources; and if any one should move or put to the vote a proposition for applying that money to any other purpose, except in case of the enemy sailing against the city with a naval armament, and its being necessary to defend themselves, they declared it a capital offence.
