The calamitous consequences of this defeat came upon Athens in thick and rapid succession. The united exiles, having carried their point in Bœotia, proceeded to expel the philo-Athenian government both from Phocis and Locris, and to carry the flame of revolt into Eubœa. To this important island Pericles himself proceeded forthwith, at the head of a powerful force; but before he had time to complete the reconquest, he was summoned home by news of a still more formidable character. The Megarians had revolted from Athens. By a conspiracy previously planned, a division of hoplites from Corinth, Sicyon, and Epidaurus, was already admitted as garrison into their city: the Athenian soldiers who kept watch over the Long Walls had been overpowered and slain, except a few who escaped into the fortified port of Nisæa. As if to make the Athenians at once sensible how seriously this disaster affected them, by throwing open the road over Geranea, Plistoanax, king of Sparta, was announced as already on his march for an invasion of Attica. He did in truth conduct an army, of mixed Lacedæmonians and Peloponnesian allies, into Attica, as far as the neighbourhood of Eleusis and the Thriasian plain. He was a very young man, so that a Spartan of mature years, Cleandridas, had been attached to him by the ephors as adjutant and counsellor. Pericles, it is said, persuaded both the one and the other, by means of large bribes, to evacuate Attica without advancing to Athens. We may fairly doubt whether they had force enough to adventure so far into the interior, and we shall hereafter observe the great precautions with which Archidamus thought it necessary to conduct his invasion, during the first year of the Peloponnesian War, though at the head of a more commanding force. Nevertheless, on their return, the Lacedæmonians, believing that they might have achieved it, found both of them guilty of corruption. Both were banished: Cleandridas never came back, and Plistoanax himself lived for a long time in sanctuary near the temple of Athene at Tegea, until at length he procured his restoration by tampering with the Pythian priestess, and by bringing her bought admonitions to act upon the authorities at Sparta.
So soon as the Lacedæmonians had retired from Attica, Pericles returned with his forces to Eubœa, and reconquered the island completely. With that caution which always distinguished him as a military man, so opposite to the fatal rashness of Tolmides, he took with him an overwhelming force of fifty triremes and five thousand hoplites. He admitted most of the Eubœan towns to surrender, altering the government of Chalcis by the expulsion of the wealthy oligarchy called the
