History of the Peloponnesian War

Instead of meeting with the usual honors accorded to the parent city by every other colony at public assemblies, such as precedence at sacrifices, Corinth found herself treated with contempt by a power, which in point of wealth could stand comparison with any even of the richest communities in Hellas, which possessed great military strength, and which sometimes could not repress a pride in the high naval position of an island whose nautical renown dated from the days of its old inhabitants, the Phaeacians. This was one reason of the care that they lavished on their fleet, which became very efficient; indeed they began the war with a force of a hundred and twenty galleys.

All these grievances made Corinth eager to send the promised aid to Epidamnus. Advertisement was made for volunteer settlers, and a force of Ambraciots, Leucadians, and Corinthians was despatched.
