Battle of the Isère River
The Battle of the Isère River (8 August 121 BC) took place near the modern day French town of Valence at the confluence of the Isère and Rhône rivers. A first confrontation had been won by Gnaeus Domitius Ahenobarbus at the Battle of Vindalium, further south in the Rhône Valley, before Ahenobarbus and Quintus Fabius Maximus Allobrogicus joined their forces, defeating a confederation of Allobroges, Arverni and some Salluvii warriors at the Isère River.

Roman consular legions were dispatched into Gaul repeatedly over a time period stretching from 125 to 121 BC to assist allies who repeatedly had come under attack from various Gallic tribes, most prominently the Salluvii, Allobroges, and Arverni. Each year during this time, a newly elected consul was dispatched by the Senate to Cisalpine Gaul in an effort to finally end the threat posed by these tribes towards the Roman allies in the region, and ultimately, to establish direct Roman control of the area.
