Julius Caesar Germanicus, grandson of Emperor Augustus, was called “Germanicus” not because he liked the Germanic peoples; rather, he was engaged in a ruthless, scorched earth campaign against them. Nevertheless, he managed to accomplish very little; mainly to show that the Roman Empire, despite all its might, could not possibly conquer Germania.
In this case, the concept of “steamrolling” can perhaps be intended in an almost literal sense. Tacitus makes it clear for us in his “Annals” that the Romans were going into Germania with in mind something much different than “bringing civilization” to those primitive peoples. No, no such silly idea; the Romans were there to teach those Barbarians a lesson. For this, they were burning villages, slaughtering everyone, or taking as slaves, as Tacitus says, even “the helpless from age or sex.” Germanicus’ name, evidently, didn’t imply that he loved Germanic people. Again, using a modern term, we could say that the Romans were practicing a scorched earth campaign, if not an outright war of extermination.
