History of the Peloponnesian War

While Scione was invested, Perdiccas sent a herald to the Athenian generals, and concluded an arrangement with the Athenians, through his hatred of Brasidas in consequence of the retreat from Lyncus; having begun to negotiate for it from that very time.

And, as Isagoras the Lacedaemonian then happened to be on the point of taking an army by land to join Brasidas, Perdiccas, partly because Nicias advised him, since he had come to terms with the Athenians, to give them some clear proof of his being a firm friend; and partly because he himself wished the Lacedaemonians never again to go to his territories; won over to his views his friends in Thessaly, (for he was always intimate with the principal men,) and stopped the army and its equipments, so that they did not even try the mind of the Thessalians on the subject.

Isagoras, however, Ameinias, and Aristeus, themselves came to Brasidas, being commissioned by the Lacedaemonians to inspect the state of affairs; and took from Sparta, in opposition to the spirit of their laws, some of their young men, with a view to appointing them to the command in the cities, instead of intrusting it to any that might happen to be there at present. Accordingly, he appointed Clearidas son of Cleonymus to the command in Amphipolis, and Pasitelidas son of Hegesander in Torone.
