History of the Peloponnesian War

Demosthenes then, disposing his army by two hundred and more in a company, and in some less, [at certain distances], seized on all the higher grounds to the end that the enemies, compassed about on every side, might the less know what to do or against what part to set themselves in battle and be subject to the shot of the multitude from every part; and when they should make head against those that fronted them, be charged behind;

and when they should turn to those that were opposed to their flanks, be charged at once both behind and before. And which way soever they marched, the light-armed and such as were meanliest provided of arms followed them at the back with arrows, darts, stones, and slings, who have courage enough afar off, and could not be charged, but would overcome flying, and also press the enemies when they should retire. With this design Demosthenes both intended his landing at first and afterwards ordered his forces accordingly in the action.
