vast armies, and drove the Germans beyond the river Elbe; removing two other tribes who submitted, the Ubii and Sicambri, into Gaul, and settling them in the country bordering on the Rhine. Other nations also, which broke into revolt, he reduced to submission. But he never made war upon any nation without just and necessary cause; and was so far from being ambitious either to extend the empire, or advance his own military glory, that he obliged the chiefs of some barbarous tribes to swear in the temple of Mars the Avenger 140, that they would faithfully observe their engagements, and not violate the peace which they had implored.

Even those who engaged most frequently and with the greatest perfidy in their rebellion, he never punished more severely than by selling their captives, on the terms (85) of their not serving in any neighbouring country, nor being released from their slavery before the expiration of thirty years. By the character which he thus acquired, for virtue and moderation, he induced even the Indians and Scythians, nations before known to the Romans by report only, to solicit his friendship, and that of the Roman people, by ambassadors.
