He therefore persuaded Peisias, the Argive, who held the position of general at Argos, to occupy Oneum A mountain range, south-east of Corinth, over which the road from Northern Greece into Peloponnesus passed. 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 with367 B.C. two thousand hoplites, having provisions for seven days.

Within this number of days the Thebans arrived and crossed over Oneum, and all the allies thereupon marched against Achaea, under the leadership of Epaminondas.
