He was given the tribunician power for a second term of three years, the duty of subjugating Germany was assigned him, and the envoys of the Parthians, after presenting their instructions to Augustus in Rome, were bidden to appear also before him in his province. But when the revolt of [llyricum was reported, he was transferred to the charge of a new war, the most serious of all foreign wars since those with Carthage, which he carried on for three years with fifteen legions and a corresponding force of auxiliaries, amid great difficulties of every kind and the utmost scarcity of supplies. But though he was often recalled, he none the less kept on, for fear that the enemy, who were close at hand and very strong, might assume the offensive if the Romans gave ground. He reaped an ample reward for his perseverance, for he completely subdued and reduced to submission the whole of lyricum, which is bounded by Italy and the kingdom of Noricum, by Thrace and Macedonia, by the Danube, and by the Adriatic sea.
