Roman armies under Germanicus pursued several more campaigns against the Germanic tribes of the Marcomanni, Hermunduri, Chatti, Cherusci, Bructeri, and Marsi. Overcoming several mutinies in the armies along the Rhine, Germanicus defeated the Germanic tribes of Arminius in a series of battles culminating in the Battle of the Weser River.
