7-06. The Teutonic Invasions of Italy and Gaul
Now at last they prepared a march upon Italy. In the spring of 102 the main mass of the united hordes began to move southwards. Only one section, of about 6000 men — the nucleus of the later tribe of the Aduatuci — remained behind in Belgica to guard the spoils. Doubtless with a view to the difficulties of the passage of the Alps, especially in the matter of supply, the invading host was before long divided into three columns. The plan was that the Teutones and Ambrones should make their way into the plain of the Po from the western side, crossing the Maritime Alps, while the Cimbri and the Tigurini should make a wide flanking movement and enter from the north, the former by way of the Tridentine, the latter by way of the Noric Alps. But the attempt was planned on too vast a scale, and was wrecked by the military skill of Marius. The Ambrones and Teutones were annihilated in the double battle near Aquae Sextiae (summer 102), while the fate of the Cimbri overtook them in the following year. They had already reached the soil of Italy, into which they had forced their way after a victorious encounter with Quintus Lutatius Catulus on the Adige,when (30 July 101), on the plains of Vercellae, the so-called Campi Raudii, they were utterly routed by the united forces of Marius and Catulus. The Tigurini, who were to form the third invading force, received the news of the defeat of the Cimbri when they were still on the Noric Alps, and immediately turned round and retired to their own country. Thus the great invasion of the northern barbarians was defeated, and Western Europe could once more breathe freely.
We saw above that about B.C. 100, doubtless in connexion with the appearance of the Cimbri and Teutones in South Germany, the line of the Main was crossed by the Germanic peoples, and the settlement of the territory between that and the Danube began. Less than a generation later there was another attempt to extend the Germanic sphere of influence westward over Gaul. About the year B.C. 71, on the invitation of the powerful tribe of the Sequani, Ariovistus chief of the Suebi crossed the Rhine with 15,000 warriors to serve as mercenaries to the Sequani against their neighbours the Aedui. But after the victory was won, the strangers did not return to their own land but remained on the western side of the Rhine and established themselves in the territory of their employers, taking possession of about a third of it, presumably at its northern extremity. Strengthened by large accessions from the home-land this Germanic settlement on Gaulish territory — it consisted of the Vangiones, Nemetes and Tribocci, and finally extended over the whole of the left side of the Rhine valley, eastward of the Vosges — soon became a menace to all the surrounding tribes. A united attempt, in which the Aedui took a leading part, to expel the intruders by force of arms ended after months of indecisive fighting in a crushing defeat of the Gauls (at Admagetobrgia), apparently in the year B.C. 61. Gaul lay defenceless at the feet of the victors, and they did not fail to make the most of their success. The Aedui and all their adherents were forced to give hostages and to pay a yearly tribute. None dared to oppose the conquerors, who already regarded the whole of Gaul as their prey. They pursued their work deliberately and systematically, constantly bringing in new swarms of their compatriots, chiefly Suebi and Marcomanni, and assigning them lands in the territories which they had subjugated. Settlers came even from Jutland, Endusi and Harudes 24,000 strong, and on their arrival the Sequani were forced to give up another third of their territory to the new-comers. Thus the power of Ariovistus became very formidable. The establishment of a great Germanic Empire over the whole of Gaul seemed not far distant.
At other points also the Teutons were preparing to cross the Rhine. It seemed as if the example set by Ariovistus would lead to a general invasion of Gaul, flood the whole country with Germans, and overwhelm the Gaulish race. The movement began on the upper Rhine, on the Helvetic border. The Helveti had been obliged, as we have already seen, to retire further and further before the pressure of the Germans, until finally all the country north of the Lake of Constance was lost to them, and the Rhine became their northern frontier. Even here they were not allowed to rest. A short time after the appearance of Ariovistus the Teutons had again endeavoured to enlarge their border towards the south, and there ensued a long struggle upon the Rhine frontier. It was only by their utmost efforts that the Helveti were able to beat off the attacks of their opponents. Weary of the constant struggle, they at last resolved (B.C. 61) to leave their territory. This, as we have seen, they did three years later, when some smaller tribes, among them the Germanic Tulingi (p. 189 sup.), threw in their lot with them. The Jura region, the entrance to southern Gaul, thus lay open to the Teutons. In the same year there appeared on the middle Rhine, probably in the Taunus region, a powerful Suebian army under the leadership of two brothers named Nasua (perhaps Masua) and Cimberius, and threatened to invade from this point the territory of the Treveri on the opposite bank. Finally, there was great restlessness also on the lower Rhine, among the tribes inhabiting the right bank, especially among the Usipetes and Tencteri, in consequence especially of the repeated aggressions of the warlike Suebi.

This reminded me of a recent visit to Augusta Raurica, just east of Basel on the Rhine.
It’s very connected to the later history of these conflicts, iirc, and is a fascinating experience in its own right. I highly recommend it if you’re interested in Roman history and you get the opportunity.
