In 54 BC, under encouragement from the Treveri king Indutiomarus, the Eburone king Ambiorix attacked and defeated a Roman force who had been stationed with him. He then went directly to the Atuatuci and then the Nervii, to encourage them to join in an uprising against Rome. The Menapii, Senones and Carnuti also joined in this uprising and prepared for war, but Caesar and his forces killed Indutomarius, then succeeded in repressing the rebellion and to punish his allies, ordering his men to lay waste to the region which adjoins the Aduatuci.
