About the same period the Athenians on the coast of Sicily sailed to Locris, and in a descent which they made on the country, defeated those of the Locrians who came against them, and took a guard-fort which stood on the river Halex.
The same summer the Aetolians, having before [the invasion of their country] sent as envoys to Corinth and Lacedaemon, Tolophus the Ophionean, Boriades the Eurytanian, and Tisander the Apodotian, persuaded them to send them an army to attack Naupactus, because it had brought the Athenians against them.
And the Lacedaemonians despatched about autumn three thousand heavy-armed of the allies; five hundred of whom were from Heraclea, their newly founded city in Trachis. Eurylochus, a Spartan, had the command of the force, accompanied by Macarius and Menedaeus, who were also Spartans;
When the army had assembled at Delphi, Eurylochus sent a herald to the Locri Ozole; for the route to Naupactus was through their territory, and moreover he wished to make them revolt from the Athenians.
Those amongst the Locrians who most forwarded his views were the Amphissians, who were alarmed in consequence of the enmity of the Phocians. These first gave hostages themselves, and persuaded the rest to do so, in their fear of the invading army; first the Myoneans, who were their neighbours, (for on this side Locris is most difficult to enter,) then the Ipneans, Messapians, Tritaens, Chalaeans, Tolophonians, Hessians, and Oeantheans. All these joined the expedition also. The Olpnaean gave hostages, but did not accompany them; while the Hyaeans refused to give hostages, till they took a village belonging to them, called Polis.
When every thing was prepared, and he had placed the hostages at Cytinium in Doris, he advanced with his army against Naupactus, through the territory of the Locrians; and on his march took Oeneon, one of their towns, and Eupalium; for they refused to surrender.
When they had reached the Naupactian territory, and the Aetolians also had now come to their aid, they ravaged the country, and took the [*]( We have no term exactly answering to the Greek προαστεῖον or, approach to the city; for, as Arnold observes on IV. 69. 5, it was not what we call a suburb, but rather an open space like the parks in London, partly planted with trees, and containing public walks, colonnades, temples, and the houses of some of the principal citizens. It was used as a ground for reviews of the army and for public games. At Rome the Campus Martius was exactly what the Greeks call προαστεῖον. ) suburb of the capital, which was unfortified. They also went against and took Molyenium, which, though a colony from Corinth, was subject to the Athenians.
Now Demosthenes, the Athenian, (for after what had happened in Aetolia, he was still in the neighbourhood of Naupactus) having previous notice of the armament, and being alarmed for the town, went and persuaded the Acarnanians (though with difficulty, on account of his retreat from Leucas) to go to the relief of Naupactus.
Accordingly they sent with him on board his ships a thousand heavy-armed, who threw themselves into the place and saved it. For the walls being extensive, and the garrison small, there was reason to fear that they might not hold out.
