On the day after the Romans had reached the Weser, Germanicus led his army across that river, and a partial encounter took place, in which Arminius was successful. But on the succeeding day a general action was fought, in which Arminius was severely wounded, and the German infantry routed with heavy loss. The horsemen of the two armies encountered without either party gaining the advantage. But the Roman army remained master of the ground, and claimed a complete victory. Germanicus erected a trophy in the field, with a vaunting inscription, that the nations between the Rhine and the Elbe had been thoroughly conquered by his army. But that army speedily made a final retreat to the left bank of the Rhine; nor was the effect of their campaign more durable than their trophy. The sarcasm with which Tacitus speaks of certain other triumphs of Roman generals over Germans, may apply to the pageant which Germanicus celebrated on his return to Rome from his command of the Roman army of the Rhine. The Germans were "TRIUMPHATI POTIUS QUAM VICTI." After the Romans had abandoned their attempts on Germany, we find Arminius engaged in hostilities with Maroboduus, the king of the Suevi and Marcomanni who was endeavouring to bring the other German tribes into a state of dependency on him. Arminius was at the head of the Germans who took up arms against this home invader of their liberties. After some minor engagements, a pitched battle was fought between the two confederacies, A.D. 16, in which the loss on each side was equal; but Maroboduus confessed the ascendency of his antagonist by avoiding a renewal of the engagement, and by imploring the intervention of the Romans in his defence. The younger Drusus then commanded the Roman legions in the province of Illyricum, and by his mediation a peace was concluded between Arminius and Maroboduus, by the terms of which it is evident that the latter must have renounced his ambitious schemes against the freedom of the other German tribes.
