which was advantageous to one who had to contend against many with a small force, he fortified his camp, and kept his men altogether from fighting; and he made them increase the height of the ramparts and build up the gates as if they were afraid, his manoeuvre being to make the enemy despise him, till at last when they made their assault in scattered bodies, urged by self-confidence, sallying out he put them to flight and killed many of them.

XXV.[502] The frequent defections of the Gauls in those parts were thus quieted, and also by Caesar during the winter moving about in all directions and carefully watching disturbances.  For there had come to him from Italy three legions to replace those that had perished, Pompeius having lent him two of those which were under his command, and one legion having been newly raised in Gaul upon the Padus.  But in the course of time there showed themselves, what had long in secret been planted and spread abroad by the most powerful men among the most warlike tribes, the elements of the greatest and the most dangerous of all the wars in Gaul, strengthened by a numerous body of young men armed and collected from all quarters, and by great stores brought together, and fortified cities, and countries difficult of access.  And at that time, during the winter, frozen rivers and forests buried in snow, and plains overflowed by winter torrents, and in some parts paths that could not be discovered for the depth of the snow, and in other parts the great uncertainty of a march through marshes and streams diverted from their course, seemed to place the proceedings of the insurgents altogether beyond any attempt on the part of Caesar.  Accordingly many tribes had revolted, but the leaders of the revolt were the Arvenni and the Carnuntini; Vergentorix was elected to the supreme direction of the war, he whose father the Gauls had put to death on the ground of aiming at a tyranny.
