History of the Peloponnesian War

And when they had thus preferred about two thousand, which also with crowns on their heads went in procession about the temples as to receive their liberty, they not long after made them away; and no man knew how they perished. And now at this time, with all their hearts, they sent away seven hundred men of arms more of the same men along with Brasidas.

The rest of the army were mercenaries, hired by Brasidas out of Peloponnesus. [But] Brasidas himself the Lacedaemonians sent out, chiefly because it was his own desire;

notwithstanding the Chalcideans also longed to have him, as one esteemed also in Sparta every way an active man. And when he was out, he did the Lacedaemonians very great service.
