History of the Peloponnesian War

For it happened also at this time that Ischagoras, a Lacedaemonian, was leading an army of foot unto Brasidas. And Perdiccas, partly because Nicias advised him, seeing the peace was made, to give some clear token that he would be firm, and partly because he himself desired not that the Peloponnesians should come any more into his territories, wrought with his hosts in Thessaly, having in that kind ever used the prime men, and so stopped the army and munition as they would not so much as try the Thessalians [whether they would let them pass or not].
