History of the Peloponnesian War

About the same time in the summer, Brasidas set out on his march for the Thracian places with seventeen hundred heavy infantry, and arriving at Heraclea in Trachis, from thence sent on a messenger to his friends at Pharsalus, to ask them to conduct himself and his army through the country. Accordingly there came to Melitia in Achaia Panaerus, Dorus, Hippolochidas, Torylaus, and Strophacus, the Chalcidian Proxenus, under whose escort he resumed his march,

being accompanied also by other Thessalians, among whom was Niconidas from Larissa, a friend of Perdiccas. It was never very easy to traverse Thessaly without an escort; and throughout all Hellas for an armed force to pass without leave through a neighbour's country, was a delicate step to take. Besides this the Thessalian people had always sympathized with the Athenians.

Indeed if instead of the customary close oligarchy there had been a constitutional government in Thessaly, he would never have been able to proceed; since even as it was, he was met on his march at the river Enipeus by certain of the opposite party who forbade his further progress, and complained of his making the attempt without the consent of the nation.
