History of the Peloponnesian War

For these were neighbouring tribes and hostile to the city of Heracleia, since the fortress there was established as a menace to no other territory but theirs. Accordingly, as soon as the city was founded, they began to show opposition to it, harassing it as much as they could; and at this time they defeated the Heracleotes, Xenares son of Cnidis, a Lacedaemonian and their commander, being killed, as well as some of the Heracleotes. And the winter ended, and with it the twelfth year of this war.
