V. The flight of the Athenians to Salamis had not been a willing resort. That gallant people had remained in Attica so long as they could entertain any expectation of assistance from the Peloponnesus; nor was it until compelled by despair at the inertness of their allies, and the appearance of the Persians in Boeotia, that they had removed to Salamis.
The singular and isolated policy of Sparta, which had curbed and crippled, to an exclusive regard for Spartans, all the more generous and daring principles of action, was never, perhaps, so odiously displayed as in the present indifference to an ally that had so nobly preferred the Grecian liberties to its own security. The whole of the Peloponnesus viewed with apathy the occupation of Attica, and the Spartans were employed in completing the fortifications of the isthmus.
The Athenians despatched messengers to Sparta, as did also Megara and Plataea. These ambassadors assumed a high and reproachful tone of remonstrance.
They represented the conduct of the Athenians in rejecting the overtures of the barbarians—they upbraided the Spartans with perfidy for breaking the agreement to meet the enemy in Boeotia—they declared the resentment of the Athenians at the violation of this compact, demanded immediate supplies, and indicated the plains near Thria, a village in Attica, as a fitting field of battle.
The ephors heard the remonstrance, but from day to day delayed an answer. The Spartans, according to Herodotus, were engaged in celebrating the solemnities in honour of Hyacinthus and Apollo; and this ceremonial might have sufficed as a plausible cause for procrastination, according to all the usages and formalities of Spartan manners. But perhaps there might be another and a graver reason for the delayed determination of the ephors.
When the isthmian fortifications were completed, the superstition of the regent Cleombrotus, who had superintended their construction, was alarmed by an eclipse, and he led back to Sparta the detachment he had commanded in that quarter. He returned but to die; and his son Pausanias succeeded to the regency during the continued minority of Pleistarchus, the infant heir of Leonidas [97]. If the funeral solemnities on the death of a regent were similar to those bestowed upon a deceased king, we can account at once for the delay of the ephors, since the ten days which passed without reply to the ambassadors exactly correspond in number with the ten days dedicated to public mourning. [98] But whatever the cause of the Spartan delay —and the rigid closeness of that oligarchic government kept, in yet more important matters, its motives and its policy no less a secret to contemporaneous nations than to modern inquirers—the delay itself highly incensed the Athenian envoys: they even threatened to treat with Mardonius, and abandon Sparta to her fate, and at length fixed the day of their departure. The ephors roused themselves. Among the deputies from the various states, there was then in Sparta that Chileus of Tegea, who had been scarcely less serviceable than Themistocles in managing the affairs of Greece in the isthmian congress. This able and eminent Arcadian forcibly represented to the ephors the danger of forfeiting the Athenian alliance, and the insufficient resistance against the Persian that the fortifications of the isthmus would afford. The ephors heard, and immediately acted with the secrecy and the vigilance that belongs to oligarchies. That very night they privately despatched a body of five thousand Spartans and thirty-five thousand helots (seven to each Spartan), under the command of Pausanias.
The next morning the ephors calmly replied to the angry threats of the Athenians, by protesting that their troops were already on the march, and by this time in Oresteum, a town in Arcadia, about eighteen miles distant from Sparta. The astonished deputies [99] hastened to overtake the Spartan force, and the ephors, as if fully to atone for their past procrastination, gave them the escort and additional re-enforcement of five thousand heavy-armed Laconians or Perioeci.
VI. Mardonius soon learned from the Argives (who, not content with refusing to join the Greek legion, had held secret communications with the Persians) of the departure of the Spartan troops. Hitherto he had refrained from any outrage on the Athenian lands and city, in the hope that Athens might yet make peace with him. He now set fire to Athens, razed the principal part of what yet remained of the walls and temples [100], and deeming the soil of Attica ill adapted to his cavalry, and, from the narrowness of its outlets, disadvantageous in case of retreat, after a brief incursion into Megara he retired towards Thebes, and pitched his tents on the banks of the Asopus, extending from Erythrae to Plataea. Here his force was swelled by such of the Greeks as were friendly to his cause.
VII. Meanwhile the Spartans were joined at the isthmus by the rest of the Peloponnesian allies. Solemn sacrifices were ordained, and the auguries drawn from the victims being favourable, the Greek army proceeded onward; and, joined at Eleusis by the Athenians, marched to the foot of Cithaeron, and encamped opposite the Persians, with the river of the Asopus between the armies. Aristides commanded the Athenians, at the head of eight thousand foot; and while the armies were thus situated, a dangerous conspiracy was detected and defeated by that able general.
The disasters of the war—the devastation of lands, the burning of houses—had reduced the fortunes of many of the Athenian nobles. With their property diminished their influence. Poverty, and discontent, and jealousy of new families rising into repute [101], induced these men of fallen fortunes to conspire for the abolition of the popular government at Athens, and, failing that attempt, to betray the cause to the enemy.
