History of the Peloponnesian War

When Brasidas had made his exhortation, he led away his army. And the barbarians, seeing it, pressed after them with great cries and tumult, as supposing he fled.

But seeing that those who were appointed to run out upon them [did so, and] met them which way soever they came on, and that Brasidas himself, with his chosen band, sustained them where they charged close and endured the first brunt beyond their expectation, and seeing also that afterwards continually when they charged, the other received them and fought, and when they ceased the other retired, then at length the greatest part of the barbarians forbore the Grecians that with Brasidas were in the open field, and leaving a part to follow them with shot, the rest ran with all speed after the Macedonians which were fled, of whom as many as they overtook they slew; and withal prepossessed the passage, which is a narrow one between two hills, giving entrance into the country of Arrhibaeus, knowing that there was no other passage by which Brasidas could get away. And when he was come to the very strait, they were going about him to have cut him off.
