The very extent and general diffusion of these misdeeds rendered a corresponding chastisement impossible. It deserves to be acknowledged that the new ruler, who happily had remained in person aloof from all these occurrences, in a genuine statesmanly fashion allowed the past to be past, and exerted himself only to prevent the repetition of similar scenes. That the prominent culprits, whether from the ranks of the troops or from the insurgents, were brought to account for their crimes, was a matter of course; we may measure the punishment by the fact that when five years afterwards one of the Gallic insurgent leaders was discovered in a lurking-place, in which his wife had up to that time kept him concealed, Vespasian gave him as well as her over to the executioner. But the renegade legions were allowed to share in the fighting against the Germans, and to atone for their guilt to some extent in the hot conflicts at Treves and at Vetera. It is true, nevertheless, that the four legions of the lower Rhenish army were all dismissed, as was one of the two upper Rhenish legions that took part--one would gladly believe that the 22d was spared in honourable remembrance of its brave legate. Probably a considerable number of the Batavian cohorts met with the same fate, and not less, apparently, the cavalry regiment of the Treveri, and perhaps several other specially prominent troops. Still less than against the rebellious soldiers could proceedings be taken with the full severity of the law against the insurgent Celtic and German cantons; that the Roman legions demanded the razing of the Treverian colony of Augustus--this time for the sake not of booty but of vengeance--is at least as intelligible as the destruction, desired by the Germans, of the town of the Ubii; but as Civilis protected the one so Vespasian protected the other. Even the Germans on the left of the Rhine had, on the whole, their previous position left to them. But probably--we are here without certain tradition--there was introduced in the levy and the employment of the _auxilia_ an essential change, which diminished the danger involved in the auxiliary system. The Batavi retained freedom from taxation and a still privileged position as regards service; a part of them, not altogether inconsiderable, had withal championed in arms the cause of the Romans. But the Batavian troops were considerably diminished, and, while hitherto--as it would appear of right--officers had been placed over them from their own nobility, and the same had been at least frequently done as respects the other Germanic and Celtic troops, the officers of the _alae_ and _cohortes_ were afterwards taken predominantly from the class from which Vespasian himself was descended--from the good urban middle class of Italy and of the provincial towns organised after the Italian fashion. Officers of the position of the Cheruscan Arminius, of the Batavian Civilis, of the Treverian Classicus do not henceforth recur.
