History of the Peloponnesian War

Now it happened at that time that Ischagoras, the Lacedaemonian, was on the point of taking an army by land to join Brasidas, but Perdiccas, partly because Nicias urged him, since he had made terms with the Athenians, to give them some token of his sincerity, partly also because he himself no longer wished the Peloponnesians to enter his territory, now worked upon his friends in Thessaly, with the foremost of whom he was always on good terms, and effectually stopped the army and the expedition, to such a degree that they did not even try to obtain permission from the Thessalians.

Ischagoras, however, with Ameinias and Aristeus, came by themselves to Brasidas, having been commissioned by the Lacedaemonians to look into the situation. And they brought from Sparta, contrary to custom, some of their young men, intending to place them as governors over the cities instead of entrusting these to anybody that might chance to offer. Accordingly, they placed at Amphipolis Clearidas son of Cleonymus and at Torone Pasitelidas son of Hegesander.
