History of the Peloponnesian War

About the same time the Athenians on the coast of Sicily sailed to Locris, and in a descent which they made from the ships defeated the Locrians who came against them, and took a fort upon the river Halex.

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.

The army having assembled at Delphi, Eurylochus sent a herald to the Ozolian Locrians; the road to Naupactus lying through their territory, and he having besides conceived the idea of detaching them from Athens.

His chief abettors in Locris were the Amphissians, who were alarmed at the hostility of the Phocians. These first gave hostages themselves, and induced the rest to do the same for fear of the invading army; first, their neighbors the Myonians, who held the most difficult of the passes, and after them the Ipnians, Messapians, Tritaeans, Chalaeans, Tolophonians, Hessians, and Oeanthians, all of whom joined in the expedition; the Olpaeans contenting themselves with giving hostages, without accompanying the invasion; and the Hyaeans refusing to do either, until the capture of Polis, one of their villages.
