XIX.--There was a hill of a gentle ascent from the bottom; a dangerous and impassable marsh, not more than fifty feet broad, begirt it on almost every side. The Gauls, having broken down the bridges, posted themselves on this hill, in confidence of their position, and being drawn up in tribes according to their respective states, held all the fords and passages of that marsh with trusty guards, thus determined that if the Romans should attempt to force the marsh, they would overpower them from the higher ground while sticking in it, so that whoever saw the nearness of the position, would imagine that the two armies were prepared to fight on almost equal terms; but whoever should view accurately the disadvantage of position, would discover that they were showing off an empty affectation of courage. Caesar clearly points out to his soldiers, who were indignant that the enemy could bear the sight of them at the distance of so short a space, and were earnestly demanding the signal for action, "with how great loss and the death of how many gallant men the victory would necessarily be purchased: and when he saw them so determined to decline no danger for his renown, that he ought to be considered guilty of the utmost injustice if he did not hold their life dearer than his own personal safety."

Being accused in such a manner, he made the following reply to these charges:--"That his moving his camp had been caused by want of forage, and had been done even by their advice; that his approaching near the Romans had been a measure dictated by the favourable nature of the ground, which would defend him by its natural strength; that the service of the cavalry could not have been requisite in marshy ground, and was useful in that place to which they had gone; that he, on his departure, had given the supreme command to no one intentionally, lest he should be induced by the eagerness of the multitude to hazard an engagement, to which he perceived that all were inclined, owing to their want of energy, because they were unable to endure fatigue any longer. That, if the Romans in the meantime came up by chance, they [the Gauls] should feel grateful to fortune; if invited by the information of some one they should feel grateful to him, because
