This battle reverberated through the centuries as this author points out:

"In the nineteenth century, the battle became a powerful national symbol. In 1806, the French army of Napoleon Bonaparte decisively beat the armies of the German states. The humiliation was too big for the Germans, who started to look to the battle in the Teutoburg Forest as their finest hour. As Napoleon spoke a romanic language and presented himself as a Roman emperor, it was easy for the Germans to remind each other that they had once before defeated the welschen Erbfeind - an untranslatable expression that refers to the Latin speaking archenemies of Germany. The Teutoburg Forest became the symbol of the eternal opposition between the overcivilised and decadent Latin and the creative and vital Germanic people, between old France and new Germany."
