Y.R. 641 A numerous band of the Teutones bent on plunder invaded the territory of Noricum. The Roman consul, Papirius Carbo, fearing lest they should make an incursion into Italy, occupied the Alps at a place where the pass is narrowest. As they made no attempt in this direction he attacked them, complaining that they had invaded the people of Noricum, who were foreign friends of the Romans. It was the practice of the Romans to make foreign friends of any people for whom they wanted to intervene on the score of friendship, without being obliged to defend them as allies. As Carbo was approaching, the Teutones sent word to him that they had not known anything about this relationship between Rome and Noricum, and that for the future they would keep hands off. He praised the ambassadors, and gave them guides for their homeward journey, but privately charged the guides to take them by a longer route. He himself then marched by B.C.113 a shorter one and fell unexpectedly upon the Teutones, though they were still desisting of Livy (lxiii.) assigns this victory to the Cimbri.
