From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
A complete victory was gained with slight loss, and the Cimbri were annihilated. Those might be deemed fortunate who met death in the battle, as most did, including the brave king Boiorix; more fortunate at least than those who afterwards in despair laid hands on themselves, or were obliged to seek in the slave-market of Rome the master who might retaliate on the individual Northman for the audacity of having coveted the beauteous south before it was time.
The Tigorini, who had remained behind in the passes of the Alps with the view of subsequently following the Cimbri, ran off on the news of the defeat to their native land. The human avalanche, which for thirteen years had alarmed the nations from the Danube to the Ebro, from the Seine to the Po, rested beneath the sod or toiled under the yoke of slavery; the forlorn hope of the German migrations had performed its duty; the homeless people of the Cimbri and their comrades were no more.
