Ariovistus answered that he had not interfered with the Romans; and the Romans had no right to interfere with him. Conquerors treated their subjects as they pleased. The Aedui had begun the quarrel with him. They had been defeated, and were now his vassals. If Caesar chose to come between him and his subjects, he would have an opportunity of seeing how Germans could fight who had not for fourteen years slept under a roof. It was reported that a large body of Suevi were coming over the Rhine to swell Ariovistus's force, and that Ariovistus was on the point of advancing to seize Besançon. Besançon was a position naturally strong, being surrounded on three sides by the Doubs. It was full of military stores, and was otherwise important for the control of the Sequani. Caesar advanced swiftly and took possession of the place, and announced that he meant to go and look for Ariovistus. The army so far had gained brilliant successes, but the men were not yet fully acquainted with the nature of their commander. They had never yet looked Germans in the face, and imagination magnifies the unknown. Roman merchants and the Gauls of the neighborhood brought stories of the gigantic size and strength of these northern warriors. The glare of their eyes was reported to be so fierce that it could not be borne. They were wild, wonderful, and dreadful. Young officers, patricians and knights, who had followed Caesar for a little mild experience, began to dislike the notion of these new enemies. Some applied for leave of absence; others, though ashamed to ask to be allowed to leave the army, cowered in their tents with sinking hearts, made their wills, and composed last messages for their friends. The centurions caught the alarm from their superiors, and the legionaries from the centurions. To conceal their fear of the Germans, the men discovered that, if they advanced farther, it would be through regions where provisions could not follow them, and that they would be starved in the forests. At length, Caesar was informed that if he gave the order to march, the army would refuse to move.
