Meanwhile a report had spread that an army was cut off, and a body of Germans on full march to invade Gaul; so that, under the terror of this news, there were those whose cowardice would have emboldened them to demolish the bridge upon the Rhine, had not Agrippina forbidden the infamous attempt. This high-minded woman took upon herself all the duties of a general, and distributed to the soldiers, gratuitously, medicines and clothes, according as anyone was in want or wounded. Caius Plinius, the writer of the German wars, relates that she stood at the head of the bridge as the legions returned, and bestowed on them thanks and praises; a behavior which sunk deep into the heart of Tiberius, for these attentions he thought were not disinterested; nor was it against foreigners she sought to win the army; for nothing was now left the generals to do, when a woman paid her visits of inspection to the companies, attended the standards, and presumed to distribute largesses; as if before she had shown but small tokens of ambitious designs in carrying her child (the son of the general) in a soldier's uniform about the camp and desiring that he be styled Cæsar Caligula. Already Agrippina was in greater credit with the army than the lieutenants-general, or even the generals--a woman had suppressed a sedition which the authority of the Emperor was not able to restrain. These jealousies were inflamed and ministered to by Sejanus, who was well acquainted with the temper of Tiberius, and supplied him with materials for hatred, prospectively, that he might treasure them up in his heart and draw them out augmented in bitterness.
