History of the Peloponnesian War

Now when these made a sally from Spartolus, the Athenians were drawn into a battle with them under the very walls of the city, and although the hoplites of the Chalcidians and some mercenaries with them were defeated by the Athenians and retreated into Spartolus, the cavalry of the Chalcidians and the light-armed troops defeated the Athenian cavalry and light-troops;

for the Athenians had a few targeteers from the land called Crousis,l and just after the battle was over another force of targeteers came from Olynthus to the help of the garrison.

And when the light-armed troops in Spartolus saw them, emboldened by these accessions and because they had not been worsted before, they again, assisted by the Chalcidian cavalry and those who had newly come to their support, attacked the Athenians, who now fell back upon the two companies which they had left with their baggage.

And whenever the Athenians advanced, they gave way, but when the Athenians retreated they kept close at their heels, hurling javelins at them. Then the Chalcidian cavalry, riding up, kept charging the Athenians wherever opportunity offered, and throwing them into utter panic routed them and pursued them to a great distance.
