History of the Peloponnesian War

When the Plataeans had so spoken, Archidamus answered and said: "What you say is just, men of Plataea, if what you do is consistent with your words. For according as Pausanias bestowed that privilege upon you, so do you assert your own independence and help us to set free the others also who, having shared in the dangers of that time, swore the same oaths with you, and are now in subjection to the Athenians; for it is to recover their freedom and that of the rest that these great preparations for war have been made. Therein you should take part, if possible, and yourselves abide by the oaths; otherwise keep quiet, as we have already proposed, continuing to enjoy your own possessions; take part with neither side, receive both sides as friends but for hostile purposes neither.

And this will be satisfactory to us." Thus spoke Archidamus; and the Plataean envoys, on hearing him, went into the city, and after reporting to the people what had been said, answered him, that it was impossible for them to do what he proposed without the consent of the Athenians--for their children and wives were in Athens '-adding that they feared for the very existence of the state; for after the departure of the Lacedaemonians the Athenians would come and veto the plan, or else the Thebans, claiming that they were included in the stipulations about receiving both sides, would try again to seize their city.
