Secured from internal threats, Rome achieved great territorial gains in both the East and the West. In the West, following humiliating defeats at the hands of the Sugambri, Tencteri and Usipetes tribes in 16 BC, Roman armies pushed north and east out of Gaul to subdue much of Germania. The Pannonian revolt in 6 AD forced the Romans to cancel their plan to cement their conquest of Germania. Despite the loss of a large army almost to the man of Varus' famous defeat at the hands of the Germanic leader Arminius in the Battle of the Teutoburg Forest in 9 AD, Rome recovered and continued its expansion up to and beyond the borders of the known world. 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.
