The Teutoburg Forest myth is noteworthy in 19th century Germanic interpretations as to why the march of the Roman Empire was halted, but in reality Roman punitive campaigns into Germania continued even after that disaster, and they were intended less for conquest or expansion than they were to force barbarian tribes into some kind of political structure that would be compliant with Roman diplomatic efforts. The most famous of those incursions, led by the Roman emperor Maximinus Thrax, resulted in a Roman victory in 235 CE at the Battle at the Harzhorn Hill, which is located in the modern German state of Lower Saxony, east of the Weser river, between the towns of Kalefeld and Bad Gandersheim. After the Marcomannic Wars, the Romans even managed to occupy the provinces of Marcomannia and Sarmatia, corresponding to modern Czech Republic, Slovakia and Bavaria/Austria/Hungary north of Danube. Final plans to annex those territories were discarded by Commodus deeming the occupation of the region too expensive for the imperial treasury.
