Invasion of Italy.
In the year B.C., 105 the Cimbrians, under their king Boiorix, advanced to the invasion of Italy. They were opposed on the right bank of the Rhone by the proconsul Cæpio, and on the left by the consul Gnæus Mallius Maximus, and the consular Marcus Aurelius Scaurus. The first attack fell on the latter general, who was taken prisoner and his corps routed. Maximus then ordered his colleague to bring his army across the Rhone, where the Roman force stood confronting the whole Cimbrian army, but Cæpio refused. The mutual jealousy of these generals, and refusal to co-operate, led to one of the most disastrous defeats which the Romans ever suffered. No less than eighty thousand soldiers, and half as many more camp followers, perished. The battle of Aransio (Orange) filled Rome with alarm and fear, and had the Cimbrians immediately advanced through the passes of the Alps to Italy, overwhelming disasters might have ensued.
Marius called to command.
In this crisis, Marius was called to the supreme command, hated as he was by the aristocracy, which still ruled, and in defiance of the law which prohibited the holding of the consulship more than once. He was accompanied by a still greater man, Lucius Sulla, destined to acquire great distinction. Marius maintained a strictly defensive attitude within the Roman territories, training and disciplining his troops for the contest which was yet to come with the most formidable antagonists the Romans had ever encountered, and who were destined in after times to subvert the empire.
Battle of Aquæ Sextiæ.
The Cimbri formed a confederation with the Helvetii and the Teutons, and after an unsuccessful attempt to sweep away the Belgæ, who resisted them, concluded to invade Italy, through Roman Gaul and the Western passes of the Alps. They crossed the Rhone without difficulty, and resumed the struggle with the Romans. Marius awaited them in a well-chosen camp, well fortified and provisioned, at the confluence of the Rhone and the Isère, by which he intercepted the passage of the barbarians, either over the Little St. Barnard—the route Hannibal had taken—or along the coast. The barbarians attacked the camp, but were repulsed. They then resolved to pass the camp, leaving an enemy in the rear, and march to Italy. Marius, for six days, permitted them to defile with their immense baggage, and when their march was over, followed in the steps of the enemy, who took the coast road. At Aquæ Sextiæ the contending parties came into collision, and the barbarians were signally defeated; the whole horde was scattered, killed, or taken prisoners. It would seem that these barbarians were Teutons or Germans; but on the south side of the Alps, the Cimbri and Helvetii crossed the Alps by the Brenner Pass, and descended upon the plains of Italy. The passes had been left unguarded, and the Roman army, under Catulus, on the banks of the Adige, suffered a defeat, and retreated to the right bank of the Po. The whole plain between the Po and the Alps was in the hands [pg 505] of the barbarians, who did not press forward, as they should have done, but retired into winter quarters, where they became demoralized by the warm baths and abundant stores of that fertile and lovely region. Thus the Romans gained time, and the victorious Marius, relinquishing all attempts at the conquest of Gaul, conducted his army to the banks of the Po, and formed a junction with Catulus.
Battle of Vercillæ.
The two armies met at Vercillæ, not far from the place where Hannibal had fought his first battle on the Italian soil. The day of the battle was fixed beforehand by the barbaric general and Marius, on the 30th of June, B.C. 101. A complete victory was gained by the Romans, and the Cimbri were annihilated. The victory of the rough plebeian farmer was not merely over the barbarians, but over the aristocracy. He became, in consequence, the leading man in Rome. He had fought his way from the ranks to the consulship, and had distinguished himself in all the campaigns in which he fought. In Spain, he had arisen to the grade of an officer. In the Numantine war he attracted, at twenty-three, the notice of Scipio. On his return to Rome, with his honorable scars and military éclat, he married a lady of the great patrician house of the Julii. At forty, he obtained the prætorship; at forty-eight, he was made consul, and terminated the African war, and his victories over the Cimbri and Teutons enabled him to secure his re-election five consecutive years, which was unexampled in the history of the republic. As consul he administered justice impartially, organized the military system, and maintained in the army the strictest discipline. He had but little culture; his voice was harsh, and his look wild. But he was simple, economical, and incorruptible. He stood aloof from society and from political parties, exposed to the sarcasms of the aristocrats into whose ranks he had entered.
Reforms of Marius.
He made great military reforms, changing the burgess levy into a system of enlistments, and allowing every free-born citizen to enlist. He abolished the aristocratic classification, reduced the infantry of the line [pg 506] to a level, and raised the number of the legion from four thousand two hundred to six thousand, to which he gave a new standard—the silver eagle, which proclaims the advent of emperors. The army was changed from a militia to a band of mercenaries.
