Detmold is a city in the Teutoburg Forest region of Western Germany. Teutoburg Forest is the name of a low mountain range that begins right on the southwestern borders of the city. It was presumed by 19th century historians to be identic with the saltus Teutoburgiensis of Roman annals, site of a decisive battle between Roman troops commanded by general Publius Quinctilius Varus and a confederation of Teutonic tribes under the leadership of the Cheruscian lord Arminius (whose name was later Germanised to "Hermann") in 9 AD. "Hermann the Cheruscian" was idealised as a German national hero during the 19th-century spirit of romantic nationalism. Archaeological digs since 1988 have identified the actual site of the battle, Kalkriese hill, near Osnabrück and Minden.

In September 9 CE, the Romans suffered one of the greatest defeats in their history in the Teutoburg Forest. Three legions (the Seventeenth, Eighteenth, and Nineteenth) were destroyed; general Publius Quintilius Varus was forced to commit suicide. The site of one of the fights of this battle has been discovered at Kalkriese, north of modern Osnabrück.
