 A negotiation between the Romans and Gannascus was arranged under the auspices of the 'Greater Chauci', which the Romans used as an opportunity to assassinate their opponent.The Chauci were outraged by the act of bad faith, so the emperor Claudius forbade further attacks on the Germans in an effort to ease tensions, and the Romans withdrew to the Rhine.In AD 69 the Batavi and other tribes rose against Roman rule in the Revolt of the Batavi, becoming a general uprising by all the Germans in the region.
