In 105 BC, the allies defeated another Roman army near Arausio, and went on to harry Spain, Gaul, Noricum, and northern Italy. They split up in two groups in 103 BC, with the Teutones and Ambrones marching on a western route through the Provincia and the Cimbri and Tigurini crossing the eastern Alps (probably by the Brenner Pass). While the Teutones and Ambrones were slaughtered in 102 BC by Gaius Marius, the Cimbri and the Tigurini wintered in the Padan plain. The following year, Marius virtually destroyed the Cimbri in the battle of Vercellae. The Tigurini, who had planned on following the Cimbri, turned back over the Alps with their booty and joined those of the Helvetians who had not participated in the raids.
