History of the Peloponnesian War

The same summer the Aetolians, who before the Athenian expedition had sent an embassy to Corinth and Lacedaemon, composed of Tolophus, an Ophionian, Boriades, an Eurytanian, and Tisander, an Apodotian, obtained that an army should be sent them against Naupactus, which had invited the Athenian invasion.

The Lacedaemonians accordingly sent off towards autumn three thousand heavy infantry of the allies, five hundred of whom were from Heraclea, the newly-founded city in Trachis, under the command of Eurylochus, a Spartan, accompanied by Macarius and Menedaius, also Spartans.
