So they left Potidaea under a truce and went into Chalcidice or wherever each was able to go. The Athenians, however, blamed the generals for granting terms without consulting them—for they thought they could have become masters of the place on their own terms; and afterwards sent settlers of their own into Potidaea and colonized it. These things happened in the winter, and so ended the second[*](430 B.C.) year of this war of which Thucydides wrote the history.
In the ensuing summer the Peloponnesians and their allies did not invade Attica, but made an expedition against Plataea. Their leader was Archidamus son of Zeuxidamus, king of the Lacedaemonians, and when he had encamped his army he was about to ravage the land; but the Plataeans straightway sent envoys to him, who spoke as follows: "
Archidamus and Lacedaemonians, you are acting unjustly, and in a manner unworthy either of yourselves or of the fathers from whom you are sprung, when you invade the territory of the Plataeans. For Pausanias son of Cleombrotus, the Lacedaemonian, when he had freed Hellas from the Persians, together with such of the Hellenes as chose to share the danger of the battle that took place in our territory, offered sacrifice in the market-place of the Plataeans to Zeus Eleutherius, and calling together all the allies restored to the Plataeans their land and city to hold and inhabit in independence, and no one was ever to march against them unjustly or for their enslavement; but in that case the allies then present were to defend them with all their might.
These privileges your fathers granted to us on account of the valour and zeal we displayed amid those dangers, but you do the very contrary; for with the Thebans, our bitterest enemies, you are come to enslave us.
But calling to witness the gods in whose names we then swore and the gods of your fathers and of our country, we say to you, wrong not the land of Plataea nor violate your oaths, but suffer us to live independent, according as Pausanias granted that to us as our right."
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.
But he, endeavouring to reassure them with regard to these matters, said: "You need only consign the city and your houses to us, the Lacedaemonians, pointing out to us the boundaries of your land and telling us the number of your trees and whatever else can be numbered; then as for yourselves migrate to whatever place you please, remaining there while the war lasts; but as soon as the war is over we will give back to you whatever we have received; until then we will hold it all in trust, working the land and paying you whatever rent will satisfy you."
