History of the Peloponnesian War

The same summer, the Aetolians, having sent their ambassadors, Tolophus, an Ophionian, Boryades, an Eurytanian, and Tisander, an Apodotian, to Corinth and Lacedaemon, persuaded them to send an army against Naupactus for that it harboured the Athenians against them.

And the Lacedaemonians, towards the end of autumn, sent them three thousand men of arms of their confederates of which five hundred were of Heracleia, the new-built city of Trachinia. The general of the army was Eurylochus, a Spartan, with whom Macarius and Menedaeus went also along, Spartans likewise.
