Diodorus (xv, 68) states that the whole space across, from Kenchreæ on one sea to Lechæum on the other, was trenched and palisaded by the Athenians and Spartans. But this cannot be true, because the Long Walls were a sufficient defence between Corinth and Lechæum; and even between Corinth and Kenchreæ, it is not probable that any such continuous line of defence was drawn, though the assailable points were probably thus guarded. Xenophon does not mention either trench or palisade. [548] Xen. Hellen. vii, 1, 14-17; Diodor. xv, 68. Having joined his Peloponnesian allies, Arcadians, Eleians, and Argeians, he was more than a match for the Spartan and Athenian force, which appears now to have confined itself to Corinth, Lechæum, and Kenchreæ. He ravaged the territories of Epidaurus, Trœzen, and Phlius; and obtained possession of Sikyon as well as of Pellênê.[549] At Sikyon, a vote of the people being taken, it was resolved to desert Sparta, to form alliance with Thebes, and to admit a Theban harmost and garrison into the acropolis; Euphron, a citizen hitherto preponderant in the city by means of Sparta and devoted to her interest, now altered his politics and went along with the stronger tide.[550] We cannot doubt also that Epaminondas went into Arcadia to encourage and regulate the progress of his two great enterprises,—the foundation of Messênê and Megalopolis; nor does the silence of Xenophon on such a matter amount to any disproof. These new towns having been commenced less than a year before, cannot have been yet finished, and may probably have required the reappearance of his victorious army. The little town of Phlius,—situated south of Sikyon and west of Corinth,—which was one of the most faithful allies of Sparta, was also in great hazard of being captured by the Phliasian exiles. When the Arcadians and Eleians were marching through Nemea to join Epaminondas at Oneium, these exiles entreated them only to show themselves near Phlius; with the assurance that such demonstration would suffice to bring about the capture of the town. The exiles then stole by night to the foot of the town walls with scaling-ladders, and there lay hid, until, as day began to break, the scouts from the neighboring hill Trikaranum announced that the allied enemies were in sight. While the attention of the citizens within was thus engaged on the other side, the concealed exiles planted their ladders, overpowered the few unprepared guards, and got possession of the acropolis. Instead of contenting themselves with this position until the allied force came up, they strove also to capture the town; but in this they were defeated by the citizens, who, by desperate efforts of bravery, repulsed both the intruders within and the enemy without; thus preserving their town.[551] The fidelity of the Phliasians to Sparta entailed upon them severe hardships through the superiority of their enemies in the field, and through perpetual ravage of their
