XIV. Meanwhile, Cleomenes, chafed at the failure of his attempt on the Athenian liberties, and conceiving, in the true spirit of injustice, that he had been rather the aggrieved than the aggressor, levied forces in different parts of the Peloponnesus, but without divulging the object he had in view . That object was twofold - vengeance upon Athens, and the restoration of Isagoras. At length he threw off the mask, and at the head of a considerable force seized upon the holy city of Eleusis. Simultaneously, and in concert with the Spartan, the Boeotians forcibly took possession of Oenoe and Hysix - two towns on the extremity of Attica while from Chalcis (the principal city of the Isle of Euboea which fronted the Attic coast) a formidable band ravaged the Athenian territories. Threatened by this threefold invasion, the measures of the Athenians were prompt and vigorous. They left for the present unavenged the incursions of the Boeotians and Chalcidians, and marched with all the force they could collect against Cleomenes at Eleusis. The two armies were prepared for battle, when a sudden revolution in the Spartan camp delivered the Athenians from the most powerful of their foes. The Corinthians, insnared by Cleomenes into measures, of the object of which they had first been ignorant, abruptly retired from the field. Immediately afterward a dissension broke out between Cleomenes and Demaratus, the other king of Sparta, who had hitherto supported his colleague in all his designs, and Demaratus hastily quitted Eleusis, and returned to Lacedaemon. At this disunion between the kings of Sparta, accompanied, as it was, by the secession of the Corinthians, the other confederates broke up the camp, returned home, and left Cleomenes with so scanty a force that he was compelled to forego his resentment and his vengeance, and retreat from the sacred city. The Athenians now turned their arms against the Chalcidians, who had retired to Euboea; but, encountering the Boeotians, who were on their march to assist their island ally, they engaged and defeated them with a considerable slaughter. Flushed by their victory, the Athenians rested not upon their arms - on the same day they crossed that narrow strait which divided them from Euboea, and obtained a second and equally signal victory over the Chalcidians. There they confirmed their conquest by the establishment of four thousand colonists  in the fertile meadows of Euboea, which had been dedicated by the islanders to the pasturage of their horses. The Athenians returned in triumph to their city. At the price of two minae each, their numerous prisoners were ransomed, and the captive chains suspended from the walls of the citadel. A tenth part of the general ransom was consecrated, and applied to the purchase of a brazen chariot, placed in the entrance of the citadel, with an inscription which dedicated it to the tutelary goddess of Athens.
"Not from the example of the Athenians only," proceeds the father of history, "but from universal experience, do we learn that an equal form of government is the best. While in subjection to tyrants the Athenians excelled in war none of their neighbours - delivered from the oppressor, they excelled them all; an evident proof that, controlled by one man they exerted themselves feebly, because exertion was for a master; regaining liberty, each man was made zealous, because his zeal was for himself, and his individual interest was the common weal."  Venerable praise and accurate distinction!
