time later that the Dalmatian legions and those on the Save obtained commanders-in-chief of their own. [Sidenote: First Pannonian war of Tiberius.] As the expeditions against the Pannonians and the Germans were, as it were, a repetition of the Raetian campaign on a more extended scale, so the leaders, who were put at their head with the title of imperial legates, were the same--once more the two princes of the imperial house, Tiberius, who, in the place of Agrippa, took up the command in Illyricum, and Drusus, who went to the Rhine, both now no longer inexperienced youths, but men in the prime of their years, and well fitted to take in hand severe work. Immediate pretexts for the waging of war in the region of the Danube were not wanting. Marauders from Pannonia, and even from the peaceful Noricum, carried pillage in the year 738 {16.} as far as Istria. Two years thereafter the Illyrian provincials took up arms against their masters, and, although they returned to obedience without offering opposition when Agrippa took over the command in the autumn of 741 {13.}, yet immediately after his death the disturbances are alleged to have begun afresh. We cannot say how far these Roman accounts correspond to the truth; certainly the pushing forward of the Roman frontier, required by the general political situation, formed the real motive and aim of the war. As to the three campaigns of Tiberius in Pannonia from 742 to 744 {12 to 10.} we are very imperfectly informed. Their result was stated by the government as the establishment of the Danube as the boundary for the province of Illyricum. That this river was thenceforth looked upon in its whole course as the boundary of Roman territory, is doubtless correct; but a subjugation in the proper sense, or even an occupation, of the whole of this wide domain by no means took place at that time. The chief resistance to Tiberius was offered by the tribes already at an earlier date declared Roman, especially by the Dalmatians; among those first effectively subdued at that time, the most noted was that of the Pannonian Breuci on the lower Save. The Roman armies, during these campaigns, probably did not cross the Drave, and did not in any case transfer their standing camp to the Danube. The region between the Save and Drave was at all events occupied, and the headquarters of the Illyrian northern army were transferred from Siscia on the Save to Poetovio (Pettau) on the middle Drave, while in the Norican region recently occupied the Roman garrisons reached as far as the Danube at Carnuntum (Petronell, near Vienna), at that time the last Norican town towards the east. The wide and vast region between the Drave and the Danube, which now forms western Hungary, was to all appearance at that time not even militarily occupied. This was in keeping with the whole plan of the offensive operations that were begun; the object sought was to be in touch with the Gallic army, and for the new imperial frontier in the north-east
