It might have been thought that the goal was reached. But one thing was still wanting to the establishment of the iron ring which was to surround the Great Germany; it was the establishment of a connection between the middle Danube and the upper Elbe--the occupation of the old home of the Boii, which with its mountain-cincture planted itself like a gigantic fortress between Noricum and Germany. The king Maroboduus, of noble Marcomanian lineage, but in his youth by prolonged residence in Rome introduced to its firmer military and political organisation, had after his return home--perhaps during the first campaign of Drusus and the transmigration, thereby brought about, of the Marcomani from the Main to the upper Elbe--not merely raised himself to be prince of his people, but had also moulded his rule not after the loose fashion of the Germanic kings, but, one might say, after the model of the Augustan. Besides his own people, he ruled over the powerful tribe of the Lugii (in what is now Silesia), and the body of his clients must have extended over the whole region of the Elbe, as the Langobardi and the Semnones are described as subject to him. Hitherto he had observed entire neutrality in presence of the other Germans as of the Romans. He gave perhaps to the fugitive enemies of the Romans an asylum in his country, but he did not actively mingle in the strife, not even when the Hermunduri had settlements assigned to them by the Roman governor on Marcomanian territory (p. 31), and when the left bank of the Elbe became subject to the Romans. He did not submit to them, but he bore all these occurrences without interrupting, on that account, his friendly relations with the Romans. By this certainly not magnanimous and scarce even so much as prudent policy, he had gained this much, that he was the last to be attacked; after the completely successful Germanic campaigns in the years 4 and 5 his turn came. From two sides--from Germany and Noricum--the Roman armies advanced against the Bohemian mountain-circle; Gaius Sentius Saturninus, advanced up the Main, clearing the dense forests from Spessart to the Fichtelgebirge with axe and fire; while Tiberius in person, starting from Carnuntum, where the Illyrian legions had encamped during the winter of the years 5-6, advanced against the Marcomani. The two armies, amounting together to twelve legions, were even in number so superior as almost to double that of their opponents, whose fighting force was estimated at 70,000 infantry and 4000 horsemen. The cautious strategy of the general seemed on this occasion also to have quite ensured success, when a sudden incident interrupted the farther advance of the Romans.
