History of the Peloponnesian War

Brasidas and Perdiccas meanwhile made an expedition together the second time into Lyncus, against Arrhibaeus; taking with them, the latter, the forces of the Macedonians under his dominion, and some heavy-armed troops of the Greeks living amongst them; the former, in addition to those of the Peloponnesians whom he had still left, the Chalcidians, Acanthians, and of the rest according to their respective strength. In all, the heavy-armed Greeks amounted to about three thousand; all the cavalry of the Macedonians with the Chalcidians went with them, amounting to nearly a thousand, and a large multitude of the barbarians besides. Having:

invaded the country of Arrhibaeus, and finding the Lyncestians encamped in the field against them, they also took up a position opposite to them.

The infantry occupying a hill on each side, and the space between being a plain, the horse of both armies, in the first place, galloped down into it, and engaged in a cavalry action. Then the Lyncestian heavy-armed having advanced first from their hill with their cavalry, and being ready for action, Brasidas and Perdiccas also, in their turn, led their forces against them, and engaged in battle, and routed the Lyncestians, and killed many of them; but the rest took refuge on the heights, and there remained quiet.

After thin, having erected a trophy, they waited two or three days, in expectation of the Illyrians, who were to join Perdiccas as mercenaries. Then Perdiccas wished to advance against the villages of Arrhibaeus, and not to sit still; but Brasidas was anxious for Mende, lest if the Athenians should sail against it before his return, it should meet with some disaster; and; as the Illyrians, moreover, had not joined them, he was not eager to advance, but rather to retreat.
