Tactics of the Opposing Generals. Darius and his army remained drawn up during the night in the same order as that in which they had first arrayed themselves; because they had not surrounded themselves with a completely entrenched camp, and, moreover, they were afraid that the enemy would attack them in the night. The success of the Persians, on this occasion, was impeded especially by this long standing on watch with their arms, and by the fear which usually springs up before great dangers; which, however, was not then suddenly aroused by a momentary panic, but had been experienced for a long time, and had thoroughly cowed their spirits.402 The army of Darius was drawn up in the following manner: for, according to the statement of Aristobulus, the written scheme of arrangement drawn 161up by Darius was afterwards captured.
