Not much later, the battle in the Teutoburg Forest put an end to Roman ambition to conquer Germania. Commander Lucius Nonius Asprenas used the First legion Germanica and the Fifth legion Alaudae to occupy the fortresses of Germania Inferior and prevent a Germanic raid on Belgica After the disaster, V Alaudae was stationed at Xanten, together with XXI Rapax, keeping an eye on the nearby tribe of the Cugerni and guarding the confluence of the Rhine and Lippe. Both units took part in the Germanic campaigns of Germanicus in the first years of the reign of Tiberius. In 43 AD, the twenty-first was replaced by XV Primigenia. At the same time, Xanten was rebuilt. We know that the Fifteenth occupied the eastern half of the base, and the Fifth the western.
