Corbulo had the intention of chastising the Chauci also; at his instigation Gannascus was put out of the way--against a deserter he held himself entitled to take this course--and he was on the point of crossing the Ems and advancing into the country of the Chauci, when not only did he receive counter-orders from Rome, but the Roman government wholly and completely altered its attitude on the lower Rhine. The emperor Claudius directed the governor to remove all Roman garrisons from the right bank. We may well conceive that the imperial general with bitter words commended the good fortune of the free commanders of Rome in former days; in this step certainly there was a conclusive admission of defeat, which had been but partially owned after the battle of Varus. Probably this restriction of the Roman occupation of Germany, which was not occasioned by any pressure of immediate necessity, was called forth by the resolve just then adopted to occupy Britain, and finds its justification in the fact that the troops were not sufficient for accomplishing both objects at once. That the order was executed, and matters remained afterwards in that position, is proved by the absence of Roman military inscriptions on the whole right bank of the lower Rhine.[67] Only isolated points for crossing and sally-ports, such as, in particular, Deutz opposite Cologne, formed exceptions from this general rule. The military road keeps here to the left bank and strictly to the course of the Rhine, while the traffic-route running behind it, cutting off the windings, pursues the straight line of communication. Here on the right bank of the Rhine there is no evidence of Roman military roads, either through the discovery of milestones or otherwise. [Sidenote: Its subsequent position.]
