About this time the Lacedaemonians founded their colony of Heraclea in Trachis, their object being the following: the Malians form in all three tribes, the Paralians, the Hiereans, and the Trachinians. The last of these having suffered severely in a war with their neighbours the Oetaeans, at first intended to give themselves up to Athens; but afterwards fearing not to find in her the security that they sought, sent to Lacedaemon, having chosen Tisamenus for their ambassador. In this embassy joined also the Dorians from the mother country of the Lacedaemonians, with the same request, as they themselves also suffered from the same enemy. After hearing them, the Lacedaemonians determined to send out the colony, wishing to assist the Trachinians and Dorians, and also because they thought that the proposed town would lie conveniently for the purposes of the war against the Athenians. A fleet might be got ready there against Euboea, with the advantage of a short passage to the island; and the town would also be useful as a station on the road to Thrace. In short, everything made the Lacedaemonians eager to found the place.
After first consulting the god at Delphi and receiving a favourable answer, they sent off the colonists, Spartans, and Perioeci, inviting also any of the rest of the Hellenes who might wish to accompany them, except Ionians, Achaeans, and certain other nationalities; three Lacedaemonians leading as founders of the colony, Leon, Alcidas, and Damagon. The settlement effected, they fortified anew the city, now called Heraclea, distant about four miles and a half from Thermopylae and two miles and a quarter from the sea, and commenced building docks, closing the side towards Thermopylae just by the pass itself, in order that they might be easily defended.
The foundation of this town, evidently meant to annoy Euboea (the passage across to Cenaeum in that island being a short one), at first caused some alarm at Athens, which the event however did nothing to justify, the town never giving them any trouble. The reason of this was as follows. The Thessalians, who were sovereign in those parts, and whose territory was menaced by its foundation, were afraid that it might prove a very powerful neighbour, and accordingly continually harassed and made war upon the new settlers, until they at last wore them out in spite of their originally considerable numbers, people flocking from all quarters to a place founded by the Lacedaemonians, and thus thought secure of prosperity. On the other hand the Lacedaemonians themselves, in the persons of their governors, did their full share towards ruining its prosperity and reducing its population, as they frightened away the greater part of the inhabitants by governing harshly and in some cases not fairly, and thus made it easier for their neighbours to prevail against them.
The same summer, about the same time that the Athenians were detained at Melos, their fellow citizens in the thirty ships cruising round Peloponnese, after cutting off some guards in an ambush at Ellomenus in Leucadia, subsequently went against Leucas itself with a large armament, having been reinforced by the whole levy of the Acarnanians except Oeniadae, and by the Zacynthians and Cephallenians and fifteen ships from Corcyra. While the Leucadians witnessed the devastation of their land, without and within the isthmus upon which the town of Leucas and the temple of Apollo stand, without making any movement on account of the overwhelming numbers of the enemy, the Acarnanians urged Demosthenes, the Athenian general, to build a wall so as to cut off the town from the continent, a measure which they were convinced would secure its capture and rid them once and for all of a most troublesome enemy.
Demosthenes however had in the meanwhile been persuaded by the Messenians that it was a fine opportunity for him, having so large an army assembled, to attack the Aetolians, who were not only the enemies of Naupactus, but whose reduction would further make it easy to gain the rest of that part of the continent for the Athenians.
The Aetolian nation, although numerous and warlike, yet dwelt in unwalled villages scattered far apart, and had nothing but light armour, and might, according to the Messenians, be subdued without much difficulty before succours could arrive. The plan which they recommended was to attack first the Apodotians, next the Ophionians, and after these the Eurytanians, who are the largest tribe in Aetolia, and speak, as is said, a language exceedingly difficult to understand, and eat their flesh raw. These once subdued, the rest would easily come in.
