History of the Peloponnesian War

Being thus persuaded, the Lacedaemonians despatched immediately Cnemus, who was still high-admiral, and the heavy-armed on board a few vessels; while they sent round orders for the fleet to prepare as quickly as possible, and sail to Leucas.

Now the Corinthians were most hearty in the cause of the Ambraciots, who were a colony of theirs; and the squadrons from Corinth and Sicyon, and those parts were in preparation; while those from Leucas, Anactorium, and Ambracia had arrived before, and were waiting for them at Leucas.

In the mean time Cnemus and the one thousand heavy-armed with him had effected a passage unobserved by Phormio, who commanded the twenty Athenian ships that kept guard off Naupactus; and they immediately prepared for the expedition by land. There were with him, of the Greeks, the Ambraciots, Leucadians, Anactorians, and his own force of one thousand Peloponnesians;

of the barbarians, one thousand Chaonians, who were not under kingly government, but who were led by Photys and Nicanor, of the family to which the chieftainship was confined, with a yearly exercise of that power. With the Chaonians some Thesprotians also joined the expedition, being [like them] not under kingly government.
