Correlative to these military arrangements on the left bank of the Rhine were those adopted on the right. In the first place the Romans took possession of the right bank itself. This step affected above all the Sugambri, in whose case certainly retaliation for the captured eagle and the crucified centurions contributed to it. The envoys sent to declare their submission, the most eminent men of the nation, were, at variance with the law of nations, treated as prisoners of war, and perished miserably in the Italian fortresses. Of the mass of the people, 40,000 were removed from their homes and settled in the north of Gaul, where they subsequently, perhaps, meet us under the name of the Cugerni. Only a small and harmless remnant of the powerful tribe was allowed to remain in their old abodes. Suebian bands were also transferred to Gaul, other tribes were pushed farther into the interior, such as the Marsi and doubtless also the Chatti; on the middle Rhine the native population of the right bank was everywhere dislodged or at any rate weakened. Along this bank of the Rhine, moreover, fortified posts, fifty in number, were instituted. In front of Mogontiacum the territory taken from the Chatti, thenceforth the canton of the Mattiaci near the modern Wiesbaden, was brought within the Roman lines, and the height of Taunus strongly fortified.[12] But above all the line of the Lippe was taken possession of from Vetera; of the two military roads furnished at intervals of a day's march with forts, on the two banks of the river, the one on the right bank at least is as certainly the work of Drusus as the fortress of Aliso in the district of the sources of the Lippe, probably the present village of Elsen, not far from Paderborn,[13] is attested to have been so. Moreover, there was the already mentioned canal from the mouth of the Rhine to the Zuider See, and a dyke drawn by Lucius Domitius Ahenobarbus through the marshy flat country between the Ems and the lower Rhine--the so-called "long bridges." Besides, there were detached Roman posts scattered through the whole region; such are subsequently mentioned among the Frisians and the Chauci, and in this sense it may be correct that the Roman garrisons reached as far as the Weser and the Elbe. Lastly, the army encamped in winter, no doubt, on the Rhine; but in summer, even though no expeditions properly so called were undertaken, uniformly in the conquered country, as a rule near Aliso.
