Augustus sought to secure the northern borders of the Roman Empire against persistent Germanic incursions from east of Gaul. He dispatched Drusus to pacify the Rhine region. In spring 11 BC, Drusus crossed the Rhine, defeated the Usipetes, bridged the Lippe, and marched through Sugambri and Cherusci territory to the Weser River before beginning his return march.
During the return march to the Rhine, the Roman army was lured into an ambush at Arbalo, where the Cherusci attacked through a narrow pass using surprise and advantageous terrain. The Germans initially held the upper hand until they pulled back, allowing the Romans to break through one of the blocked exits and escape the encirclement.
After the battle, Drusus constructed a fortified camp at the site of the engagement. The Romans ultimately secured their northern territories by the end of the campaign. Drusus died two years later after falling from his horse, ending his role in the ongoing effort to extend Roman control beyond the Rhine.
