Thus strengthened by his alliance with the Colonia Agrippinensis, Civilis resolved to attach to himself the neighbouring States, or to make war on them if they offered any opposition. He occupied the territory of the Sunici, and formed the youth of the country into regular cohorts. To hinder his further advance, Claudius Labeo encountered him with a hastily assembled force of Betasii, Tungri, and Nervii, relying on the strength of his position, as he had occupied a bridge over the river Mosa. They fought in a narrow defile without any decided result, till the Germans swam across and attacked Labeo's rear. At the same moment, Civilis, acting either on some bold impulse or by a preconcerted plan, rushed into the Tungrian column, exclaiming in a loud voice, "We have not taken up arms in order that the Batavi and Treveri may rule over the nations. Far from us be such arrogance! Accept our alliance. I am ready to join your ranks, whether you would prefer me to be your general or your comrade." The multitude was moved by the appeal, and were beginning to sheathe their swords, when Campanus and Juvenalis, two of the Tungrian chieftains, surrendered the whole tribe to Civilis. Labeo made his escape before he could be intercepted. The Betasii and Nervii, also capitulating, were incorporated by Civilis into his army. He now commanded vast resources, as the States were either completely cowed, or else were naturally inclined in his favour.
