“ But by the Germans the Roman People have been bereft of five armies, all commanded by Consuls; by the Germans, the commanders of these armies, Carbo, and Cassius, and Scaurus Aurelius, and Servilius Caepio, as also Marcus Manlius, were all routed or taken: by the Germans even the Emperor Augustus was bereft of Varus and three legions. Nor without difficulty and loss of men were they defeated by Caius Marius in Italy, or by the deified Julius in Gaul, or by Drusus or Tiberius or Germanicus in their native territories. ”
