History of the Peloponnesian War

Having pitched their camp for that day in the territory of Tanagra, they laid it waste, and passed the night there. The next day, after defeating in battle those of the Tanagraeans and the Thebans who had come out against them, and after taking some arms, and erecting a trophy, they returned, one party to the city, the other to their fleet.

And Nicias, with his sixty ships, coasted along and ravaged the maritime parts of Locris, and then returned home.

About this time the Lacedaemonians prepared to found their colony of Heraclea, in Trachiniae, with the following purpose.

The Melians form, in all, three tribes, the Paralians, Hiereans, and Trachinians. Of these, the Trachinians, having been reduced to great weakness by the Aetaeans, who border on them, intended at first to give themselves up to the Athenians; but afterwards, fearing that they could not be trusted by them, they sent to Lacedaemon, having chosen Tisamenus as their envoy.

They were joined in the embassy by the Dorians also, the mother-state of the Lacedaemonians, with the same petition; for they, too, were much injured by the Aetaeans.
