Rome was not unprepared for this invasion; to meet it, Marius had been recalled from his command in Africa, and invested with the consular power. When the division of the Ambrones and the Teutones reached the Maritime Alps, they found that general encamped in a position which lay directly in their line of march. Assaulted for three successive days, the Romans maintained themselves in their intrenchments: at last the Gauls, giving up the attempt to force them, passed on and soon reached Aquae Sextiae, whither they were followed by Marius. Marius encamped on a hill opposite the quarter of the Ambrones; between them flowed a river. The sutlers of the Roman army having descended to obtain water, encountered, in the bed of the torrent, some Gauls. A skirmish began; the Ambrones flocked in great numbers to support their comrades; soon they assembled their whole force and advanced upon the Romans. In crossing the stream they were vigorously opposed by the auxiliaries. Marius, seeing the favourable opportunity, led down his legions to the attack. Unable to withstand the shock, the Ambrones were driven back with great loss; the river ran red with their blood; the plain was covered with fugitives; and their routed forces halted not till they reached the neighbouring quarter of the Teutones. In their camp the Romans experienced more resistance from the women, who, rather than fall into the hands of their enemies, flung themselves on the hostile ranks, or perished by their own hands. Marius drew off his troops before night, and retreated to his former position on the hill. The next night he sent round 3000 men to occupy a wood in the rear of the position of the Teutones. The following morning he drew out his legions in battle array upon the slope of the hill, and sent forward his cavalry to skirmish with the enemy, and induce them to engage with him. They fell into the snare: pursuing his cavalry, they advanced to the river's edge, and there, in an evil hour, crossed it and attacked the Roman army. The contest which ensued was long and desperate; the Gauls had the advantage in numbers, the Romans in discipline and position. But while victory still hung in the balance, the 3000 Romans, issuing forth from their ambuscade, fell upon the rear of the Teutones: this produced irremediable confusion in the ranks of the Gauls. The Romans redoubled the energy of their attack, and the victory was no longer doubtful. Many perished in the field, more in the pursuit; the remainder were cut off in detail by the peasants, who assailed them on all sides.
