Although Caesar had freed him from paying tribute to the Aduztuci, he joined Catuvolcus (winter, 54 BC) in rising against the Roman forces under Q. Titurius Sabinus and I. Aurunculeius Cotta, and almost annihilated them. An attack on Quintus Cicero (brother of the orator), then quartered with a legion in the territory of the Nervii, failed owing to the timely appearance of Caesar. Ambiroix is said to have found safety across the Rhine.
