With a force comparatively small, Myronides commenced his march, entered Boeotia sixty-two days only after the battle of Tanagra, and, engaging the Boeotians at Oenophyta, obtained a complete and splendid victory (B. C. 456). This battle, though Diodorus could find no details of the action, was reckoned by Athens among the most glorious she had ever achieved; preferred by the vain Greeks even to those of Marathon and Plataea, inasmuch as Greek was opposed to Greek, and not to the barbarians. Those who fell on the Athenian side were first honoured by public burial in the Ceramichus--"As men," says Plato, "who fought against Grecians for the liberties of Greece." Myronides followed up his victory by levelling the walls of Tanagra. All Boeotia, except Thebes herself, was brought into the Athenian alliance--as democracies in the different towns, replacing the oligarchical governments, gave the moral blow to the Spartan ascendency. Thus, in effect, the consequences of the battle almost deserved the eulogies bestowed upon the victory. Those consequences were to revolutionize nearly all the states in Boeotia; and, by calling up a democracy in each state, Athens at once changed enemies into allies. From Boeotia, Myronides marched to Phocis, and, pursuing the same policy, rooted out the oligarchies, and established popular governments. The Locrians of Opus gave a hundred of their wealthiest citizens as hostages. Returned to Athens, Myronides was received with public rejoicings [194], and thus closed a short but brilliant campaign, which had not only conquered enemies, but had established everywhere garrisons of friends.
