 According to Cassius Dio, Germanicus was a popular quaestor because he acted as an advocate as much in capital jurisdiction cases before Augustus as he did before lesser judges in standard "quaestiones" (trials).He successfully defended, for example, a quastor accused of murder in AD 10 in which the prosecutor, fearing the jurors would find in favor of the defense out of deference for Germanicus, demanded a trial before Augustus.In AD 9, three Roman legions commanded by Varus were destroyed by a coalition of German tribes led by Arminius in the Battle of the Teutoburg Forest.
