His son, Germanicus, born B.C. 14, was sent, in A.D. 12, to command the forces on the Rhine. After quelling serious mutinies among his legions he crossed the Rhine and attacked and routed some of the German tribes who had been actively aggressive against the Romans. During the following year he defeated other tribes, and after his return across the Rhine he was persuaded by Segestes to aid him against his son-in-law Arminius (the Latin name for Herman), by whom Segestes was besieged and who, according to Tacitus, became in the end the deliverer of Germany from the power of the Romans. But before he was able to render this service to the German peoples he had many hardships to endure, and at the hands of Germanicus he met with severe reverses. Arminius had defeated Varus, who, by reason of that disgrace, killed himself (A.D. 10), and the despatch of Germanicus to command the German legions was ordered in the first instance to revenge the overthrow of his predecessor. Although it required several campaigns, the work of Germanicus was so effectual that he withdrew in the end, at the command of Tiberius, with advantage on his side, and, returning to Rome, enjoyed a triumph (A.D. 17). His name is preserved in history, alike for his military talents and services, for his attainments in literary pursuits, and his nobleness of mind. In the consulship of Drusus Cæsar and Caius Norbanus a triumph was decreed to Germanicus; the war continuing. He was preparing with all diligence to prosecute it in the summer, but anticipated it by a sudden irruption early in the spring into the territories of the Cattians: for he had conceived a hope that the enemy was divided into opposite parties under Arminius and Segestes, both remarkable for perfidy or fidelity toward us: Arminius was the incendiary of Germany, but Segestes had given repeated warning of an intended revolt at other times and during the banquet immediately preceding the insurrection, and advised Varus "to secure him and Arminius and all the other chiefs; that the multitude, bereft of their leaders, would not dare to attempt anything; and Varus would have an opportunity to separate the guilty from the innocent." But fate decreed it, and he was slain by Arminius. Segestes, though drawn into the war by the universal agreement of the nation in it, yet continued to disapprove of it; his detestation being augmented by motives of a domestic nature, for Arminius had carried away the daughter of Segestes, already betrothed to another: the son-in-law hated, the fathers-in-law were at enmity; and those relations which are bonds of affection between friends fomented the animosities of enemies.
