This battle being ended, and the nation and name of the Nervii being almost reduced to annihilation, their old men, who together with the boys and women we have stated to have been collected together in the fenny places and marshes, on this battle having been reported to them, since they were convinced that nothing was an obstacle to the conquerors, and nothing safe to the conquered, sent ambassadors to Caesar by the consent of all who remained, and surrendered themselves to him; and in recounting the calamity of their state said that their senators were reduced from 600 to three; that from 60,000 men they [were reduced] to scarcely 500 who could bear arms, whom Caesar, that he might appear to use compassion toward the wretched and the suppliant, most carefully spared, and ordered them to enjoy their own territories and towns, and commanded their neighbors that they should restrain themselves and their dependents from offering injury or outrage [to them].... IV THE BATTLE OF PHARSALIA AND THE DEATH OF POMPEY[46] (48 B.C.) Pompey, because he was encamped on a hill, drew up his army at the very foot of it, ever in expectation, as may be conjectured, that Caesar would expose himself to this disadvantageous situation. Caesar, seeing no likelihood of being able to bring Pompey to an action, judged it the most expedient method of conducting the war to decamp from that post, and to be always in motion; with this hope, that by shifting his camp and removing from place to place, he might be more conveniently supplied with corn, and also that by being in motion he might get some opportunity of forcing them to battle, and might by constant marches harass Pompey's army, which was not accustomed to fatigue.[47] These matters being settled, when the signal for marching was given, and the tents struck, it was observed that shortly before, contrary to his daily practise, Pompey's army had advanced farther than usual from his entrenchments, so that it appeared possible to come to an action on equal ground. Then Caesar addrest himself to his soldiers, when they were at the gates of the camp, ready to march out. "We must defer," says he, "our march at present, and set our thoughts on battle, which has been our constant wish; let us then meet the foe with resolute souls. We shall not hereafter easily find such an opportunity." He immediately marched out at the head of his troops.
