Successful as Drusus' forces were, none the less so were those of Tiberius. There, however, is less record of his battles, and the actual ground on which they were fought forms still matter for conjecture. And equally uncertain is the exact spot where the two victorious generals ultimately met. It is, however, thought by several reliable authorities to have been somewhere in the valley of the Inn, and probably not far distant from the present site of Innsbruck. This view is made the more probable from the circumstance that a Roman post was established at Wilten (now a suburb of Innsbruck) then known as Veldidena. Here probably both armies rested after a campaign of great fatigue and severity owing to the nature of the ground over which it was fought and the stubborn resistance offered by the inhabitants. Soon Veldidena, from a halting-place of armies, became a town with houses of considerable size, temples, baths, and surrounding _vallæ_, or earthen fortifications formed to defend the inhabitants from sudden attack. Although precautions of the nature we have indicated were taken wherever a Roman post or station was placed, there is no historical data to show that the Breones and other adjacent tribes who were thus brought under the Roman sway did not very speedily accommodate themselves to the new condition of things and become good and peaceful citizens of Rome. It appears probable, however, that the Rhæti did not adapt themselves to the altered conditions as speedily as did their northern neighbours, the inhabitants of Noricum, with whom certain Roman habits and customs (including the system of municipal government) already obtained. From the evidence adduced by several diligent historians and from that of one comparatively modern writer[3] in particular it is almost certain that after the sanguinary and decisive battle on the banks of the Eisack Tiberius set his face once again westward to resume his governorship of Gaul, leaving his brother, Drusus, to continue the subjection of Tyrol, and ultimately to found the important settlement of Augusta Vindelicorum, now known as Augsburg. Here the Roman general not only threw up a fortified camp, but also built a forum to encourage commerce; and soon the settlement became the most important Roman station to the north of the Central Alps.
