The result was that neither the Treviri nor the Lingones nor the 70 other rebel tribes behaved as if aware of the serious risks they were undertaking. Even the leaders did not act in concert. Civilis wandered over the wilds of the Belgic country, trying to catch or expel Claudius Labeo. Classicus ordinarily took his ease, apparently enjoying the fruits of empire. Even Tutor seemed in no hurry to garrison the Upper Rhine and block the Alpine passes. In the meantime, the Twenty-first legion made its way down from Vindonissa, while Sextilius Felix[423] advanced through Raetia with some auxiliary cohorts. These were joined by the 'Picked Horse',[424] a force that had been raised by Vitellius and then deserted to Vespasian. This was commanded by Civilis' nephew, Julius Briganticus,[425] for uncle and nephew hated each other with all the aggravated bitterness of near relatives. Tutor swelled his force of Treviri with fresh levies from the Vangiones, Triboci, and Caeracates,[426] and a stiffening of Roman veterans, both horse and foot, who had either been bribed or intimidated. These first cut up an auxiliary cohort sent forward by Sextilius Felix, but on the advance of the Roman army with its generals they loyally deserted to their old flag, and were followed by the Triboci, Vangiones, and Caeracates. Tutor, followed by his Treviri, avoided Mainz and fell back on Bingium,[427] relying on his position there, as he had broken down the bridge over the river Nava. However, Sextilius' cohorts followed him up; some traitor showed them a ford; Tutor was routed. This disaster was a crushing blow to the Treviri. The rank and file dropped their weapons and took to the fields, while some of their chieftains, hoping it might be thought that they had been the first to lay down arms, took refuge among tribes who had never repudiated the Roman alliance. The legions which had been moved, as we saw above,[428] from Novaesium and Bonn to Trier, now administered to themselves the oath of allegiance to Vespasian. This happened in Valentinus' absence. When he arrived in furious excitement, ready to spread universal ruin and confusion, the legions withdrew into the friendly territory of the Mediomatrici.[429] Valentinus and Tutor then led the Treviri forcibly back into the field, but first they killed the two Roman officers, Herennius and Numisius.[430] By diminishing the hope of pardon they tried to cement their bond of crime.
