History of the Peloponnesian War

The result was that the Athenians, suddenly and unexpectedly attacked on both sides, fell into confusion; and their left towards Eion, which had already got on some distance, at once broke and fled. Just as it was in full retreat and Brasidas was passing on to attack the right, he received a wound; but his fall was not perceived by the Athenians, as he was taken up by those near him and carried off the field.

The Athenian right made a better stand, and though Cleon, who from the first had no thought of fighting, at once fled and was overtaken and slain by a Myrcinian targeteer, his infantry forming in close order upon the hill twice or thrice repulsed the attacks of Clearidas, and did not finally give way until they were surrounded and routed by the missiles of the Myrcinian and Chalcidian horse and the targeteers.
