Two full years had now elapsed since the actual commencement of war, by the attack of the Thebans on Platæa; yet the Peloponnesians had accomplished nothing of what they expected. They had not rescued Potidæa, nor had their twice-repeated invasion, although assisted by the unexpected disasters arising from the epidemic, as yet brought Athens to any sufficient humiliation,—though perhaps the envoys which she had sent during the foregoing summer with propositions for peace, contrary to the advice of Periklês, may have produced an impression that she could not hold out long. At the same time, the Peloponnesian allies had on their side suffered little damage, since the ravages inflicted by the Athenian fleet on their coast may have been nearly compensated by the booty which their invading troops gained in Attica. Probably by this time the public opinion in Greece had contracted an unhappy familiarity with the state of war, so that nothing but some decisive loss and humiliation on one side at least, if not on both, would suffice to terminate it. In this third spring, the Peloponnesians did not repeat their annual march into Attica,—deterred, partly, we may suppose, by fear of the epidemic yet raging there,—but still more by the strong desire of the Thebans to take their revenge on Platæa. To this ill-fated city, Archidamus marched forthwith, at the head of the confederate army. But no sooner had he entered and begun to lay waste the territory, than the Platæan heralds came forth to arrest his hand, and accosted him in the following terms: “Archidamus, and ye men of Lacedæmon, ye act wrong, and in a manner neither worthy of yourselves nor of your fathers, in thus invading the territory of Platæa. For the Lacedæmonian Pausanias, son of Kleombrotus, after he had liberated Greece from the Persians, in conjunction with those Greeks who stood forward to bear their share of the danger, offered sacrifice to Zeus Eleutherius, in the market-place of Platæa; and there, in presence of all the allies, assigned to the Platæans their own city and territory to hold in full autonomy, so that none should invade them wrongfully, or with a view to enslave them: should such invasion occur, the allies present pledged themselves to stand forward with all their force as protectors. While your fathers made to us this grant, in consideration of our valor and forwardness in that perilous emergency, ye are now doing the precise contrary: ye are come along with our worst enemies, the Thebans, to enslave us. And we on our side now adjure you, calling to witness the gods who sanctioned that oath, as well as your paternal and our local gods, not to violate the oath by doing wrong to the Platæan territory, but to let us live on in that autonomy which Pausanias guaranteed.”[323] [323] Thucyd. ii, 71, 72.
