Cæsar, as he had announced, started early on the morrow of the day on which he had thus addressed his officers, and, determined on conducting his army through an open country, he turned the mountainous and difficult region just described, thus making a circuit of more than fifty miles (seventy-five kilomètres),[218] which is represented by a semi-circumference, the diameter of which would be the line drawn from Besançon to Arcey. It follows the present road from Besançon to Vesoul as far as Pennesières, and continues by Vallerois-le-Bois and Villersexel to Arcey. He could perform this distance in four days; then he resumed, on leaving Arcey, the direct road from Besançon to the Rhine by Belfort and Cernay.
On the seventh day of a march uninterrupted since leaving Besançon, he learnt by his scouts that the troops of Ariovistus were at a distance of not more than twenty-four miles (36 kilomètres).
Supposing 20 kilomètres for the day’s march, the Roman army would have travelled over 140 kilomètres in seven days, and would have arrived on the Thur, near Cernay. (By the road indicated, the distance from Besançon to the Thur is about 140 kilomètres.) At this moment, Ariovistus would have been encamped at 36 kilomètres from the Romans, to the north, near Colmar.
Informed of the arrival of Cæsar, Ariovistus sent him word “that he consented to an interview, now that the Roman general had come near, and that there was no longer any danger for him in going to him.” Cæsar did not reject this overture, supposing that Ariovistus had returned to more reasonable sentiments.
The interview was fixed for the fifth day following.[219] In the interval, while there was a frequent exchange of messages, Ariovistus, who feared some ambuscade, stipulated, as an express condition, that Cæsar should bring with him no foot soldiers, but that, on both sides, they should confine themselves to an escort of cavalry. The latter, unwilling to furnish any pretext for a rupture, consented; but, not daring to entrust his personal safety to the Gaulish cavalry, he mounted on their horses men of the 10th legion, which gave rise to this jocular saying of one of the soldiers: “Cæsar goes beyond his promise; he was to make us prætorians, and he makes us knights.”[220]
Interview between Cæsar and Ariovistus.
VI. Between the two armies extended a vast plain, that which is crossed by the Ill and the Thur. A tolerably large knoll rose in it at a nearly equal distance from either camp.[221] This was the place of meeting of the two chieftains. Cæsar posted his mounted legion at 200 paces from the knoll, and the cavalry of Ariovistus stood at the same distance. The latter demanded that the interview should take place on horseback, and that each of the two chiefs should be accompanied only by ten horsemen. When they met, Cæsar reminded Ariovistus of his favours, of those of the Senate, of the interest which the Republic felt in the Ædui, of that constant policy of the Roman people which, far from suffering the abasement of its allies, sought incessantly their elevation. He repeated his first conditions.
Ariovistus, instead of accepting them, put forward his own claims: “He had only crossed the Rhine at the prayer of the Gauls; the lands which he was accused of having seized, had been ceded to him; he had subsequently been attacked, and had scattered his enemies; if he has sought the friendship of the Roman people, it is in the hope of benefiting by it; if it becomes prejudicial to him, he renounces it; if he has carried so many Germans into Gaul, it is for his personal safety; the part he occupies belongs to him, as that occupied by the Romans belongs to them; his rights of conquest are older than those of the Roman army, which had never passed the limits of the province. Cæsar is only in Gaul to ruin it. If he does not withdraw from it, he will regard him as an enemy, and he is certain that by his death he shall gain the gratitude of a great number of the first and most illustrious personages in Rome. They have informed him by their messengers that, at this price, he would gain their good-will and friendship. But if he be left in free possession of Gaul, he will assist in all the wars that Cæsar may undertake.”
Cæsar insisted on the arguments he had already advanced: “It was not one of the principles of the Republic to abandon its allies; he did not consider that Gaul belonged to Ariovistus any more than to the Roman people. When formerly Q. Fabius Maximus vanquished the Arverni and the Ruteni, Rome pardoned them, and neither reduced them to provinces nor imposed tribute upon them. If, then, priority of conquest be invoked, the claims of the Romans to the empire of Gaul are the most just; and if it be thought preferable to refer to the Senate, Gaul ought to be free, since, after victory, the Senate had willed that she should preserve her own laws.”
