Aratus (22.4-22.5)

These, rising up from ambush as it were, fell upon him, slew the first whom they attacked, put the rest, together with Archelaüs, to panic flight, and pursued them until they were scattered and dispersed about the city.

The three hundred at once ordered him to lead the way; and as they took to the ascent their cries signalled their coming and encouraged their friends; the light of the full moon also made their arms appear more numerous to the enemy than they really were, owing to the length of their line of march, and the echoes of the night gave the impression that the shouts proceeded from many times the number of men there really were.
