In the summer of 102 the Teutones crossed the Rhone and proceeded down the left bank to meet the army of Marius, which was encamped in a strong position at the junction of the Isère and the Rhone and was well provisioned. Here he was barring both the highroads which at that time led to Italy, the route over the Little St. Bernard, and the route along the coast. The barbarians encamped in countless numbers on the wide plain in front of Marius’ camp and challenged him to battle. He, however, following the plan of remaining strictly on the defensive, stayed quietly in camp and let them spend their strength in daily attempts to storm the Roman fortifications. In vain; their impetuosity was wrecked by the arts of war as practised by the Romans and by the prudence of Marius. At last they drew off in the direction of the south, in order to march into Italy by the road along the coast. They were six days marching past the Roman camp in enormous crowds with numberless heavily-laden carts. The Romans from their walls jeered at them as they passed, asking if they had no commands for their wives. When the procession had gone by, Marius followed with his force, and camped always close beside them, but behind strong entrenchments and in favourable positions, so that he was protected against night surprises and could not be forced into an engagement against his will. In this way they travelled until they came to Aquæ Sextiæ (now Aix in Provence); from here it was only a little way to the Alps, and Marius was compelled to consider the question of a decisive battle. He pitched his camp at a place where there was no spring of water, and when his soldiers grumbled and asked him where they could get it, he pointed downwards to the river Canus (now the Arc) which flowed near the enemy’s camp. They demanded that he should at once lead them against the enemy, whilst they had still blood to spend. He answered coolly: “First we must fortify the camp.”
Whilst the soldiers were fortifying the camp Marius sent his camp-followers to the river to fetch water. For their defence they carried hatchets and axes, swords and lances. Soon a scuffle arose on the banks with the roving bands of the Ambrones who, separated from the Teutones, covered the rear of the whole army on the march. As new combatants constantly hurried to the assistance of both sides, the Ambrones at last played their full strength, thirty thousand men, and Marius was no longer able to restrain his men. In crossing the river, the Ambrones fell into disorder and the Romans, in a rush down from the heights attacked them in the rear with such force, that having suffered great loss, they fled back to their camp and barricade of wagons. Here the fight was renewed after a strange fashion, for the wives of the Ambrones, armed with swords and hatchets, rushed with wild cries to meet them as they fled, forcing them back towards the enemy, and those who saw that all was lost, fell into a frenzy and threw themselves into the midst of the combat, letting themselves be cut and hacked to pieces.
The Romans felt encouraged by this victory, but dared not give themselves over to the joy of triumph, for by far the greater number of the enemy had not yet been engaged. The great plain was still covered with myriads of Teutones, who filled the air all night with threatening cries and occupied themselves all the following day preparing for a further encounter. It was not till three days later that the fight recommenced. By break of day, Marius and his men had ranged themselves on the hill in front of the camp in order for battle. As soon as the barbarians saw them they attacked the hill with fury. The Romans waited quietly till they came within range, then threw their lances and seized their swords. There was a long and obstinate fight lasting till midday; then the Germans, weakened by their own impetuosity and the heat of the southern sun, began to give way: as they reached the plain and were in the act of reorganising their front ranks which had fallen into disarray three thousand men under Claudius Marcellus fell on them from an ambush in the rear. That decided the issue; startled at the double attack the barbarians broke up their lines and fled in wild confusion.
