History of the Peloponnesian War

At the same moment Clearidas, as he had been ordered, went out at the Thracian gate and bore down with his troops.

And so it came to pass that owing to the unexpected and sudden nature of the attack from both sides at once the Athenians were thrown into confusion; and the left wing, on the side toward Eion, which had already gone some distance in advance, was at once cut off, and fled.

(It was just when it began to retire that Brasidas, who was pressing forward against the right wing, was wounded, and the Athenians did not observe that he had fallen, but those who were near took him up and carried him from the field.) The right wing of the Athenians stood its ground better. Cleon, indeed, as he had not intended from the first to stand his ground, fled at once, and was overtaken and slain by a Myrcinian targeteer; but the hoplites, rallying at their first position on the hill, twice or thrice repulsed the attack of Clearidas, and did not give way till the Myrcinian and Chalcidian horse and the targeteers, who surrounded and hurled javelins at them, put them to flight.
