Meanwhile, the year before, the Thebans had been active and growingly successful. They turned against three near-by cities in Bœotia which were old victims of Thebes and had been granted independence under the Peace of Antalcidas. These towns were Platæa, Thespiæ, and Orchomenos. They hated Thebes from bitter memories of former oppressions and held out against her increasing presumption, although other Bœotian towns were brought into the league, and although they were themselves heavily assailed. It was 372 before Platæa was taken by surprise and all the inhabitants driven out of it. They took refuge in Athens, whose friendship for Platæa was of old times. Thebes also compelled Thespiæ to tear down her fortifications. These things only revived in Athens the ancient abhorrence of Thebes, but they fed the insolence of the Bœotians. It was probably in 375 B.C., that Pelopidas, at the head of his Sacred Band, unexpectedly fell in with two Spartan moras, each of them equal alone to his three hundred, and each under command of a polemarch. One of his men came flying to Pelopidas, exclaiming: “We have fallen into the midst of the enemy.” “Why not they into the midst of us?” answered Pelopidas. And at once he charged home. The first onset killed the two Spartan leaders. This threw the two moras into confusion, and Pelopidas, after cutting his way through, instead of retiring, turned and successfully routed each of the moras. So far as the number engaged is concerned, it was hardly more than a serious riot, but, as we have seen before, any blow at the prestige of the Spartan soldier made all Greeks shudder, and here was a new organisation or club from the unheroic city of Thebes destroying a Spartan force of twice its strength. This was a further blow to Spartan pride and new fuel for the increase of Theban self-confidence. In 374 an expedition against Phocis was checked by Spartan troops under Cleombrotus, but about this time the Athenians seem to have regained Oropus, which the Spartans had captured in 411. This year also Lacedæmonian pride was more deeply humbled before Corcyra.[a] Of this let Xenophon tell. CORCYRA [Sidenote: [375-372 B.C.]] The Lacedæmonians preparing again to send out a fleet, collected vessels to the number of sixty from Lacedæmon itself, from Corinth, Leucas, Ambracia, Elis, Zacynthus, Achaia, Epidaurus, Trœzen, Hermion, and the Halians. Appointing Mnasippus admiral, they instructed him to attend to affairs in that sea in general, and to make an attempt upon Corcyra. They sent also to Dionysius, representing that it was for his interest that Corcyra should not be in the power of the Athenians.
