C. Julius Caesar, Gallic War

When Caesar was convinced of the truth of this account from the concurring testimony of several persons, and perceived that the plans which were proposed were full of prudence, and very unlike the rash resolves of a barbarous people, he considered it incumbent on him to use every exertion, in order that the enemy might despise his small force and come to an action. For he had three veteran legions of distinguished valor, the seventh, eighth and ninth. The eleventh consisted of chosen youth of great hopes, who had served eight campaigns, but who, compared with the others, had not yet acquired any great reputation for experience and valor. Calling therefore a council, and laying before it the intelligence which he had received, he encouraged his soldiers. In order if possible to entice the enemy to an engagement by the appearance of only three legions, he ranged his army in the following manner, that the seventh, eighth, and ninth legions should march before all the baggage; that then the eleventh should bring up the rear of the whole train of baggage (which however was but small, as is usual on such expeditions), so that the enemy could not get a sight of a greater number than they themselves were willing to encounter. By this disposition he formed his army almost into a square, and brought them within sight of the enemy sooner than was anticipated.
