Epaminondas, on the other hand, wishing to bring over the Achaeans to the side of the Thebans, in order that the Arcadians and the other allies might be more inclined to give heed to them, decided that he must march forth against Achaea. He therefore persuaded Peisias, the Argive, who held the position of general at Argos, to occupy Oneum1
in advance. And Peisias, after he had learned that the guard over Oneum was being maintained carelessly by Naucles, who commanded the mercenary troops of the Lacedaemonians, and by Timomachus, the Athenian, did indeed seize the hill above Cenchreae by night with2
two thousand hoplites, having provisions for seven days.
