Excerpts from Books and Wikipedia
"Arminius's mounted warriors harassed the slow-moving column until the Roman force was so weakened it was overrun. There were few survivors and Varus took his own life." The Rhine continued to divide the Roman and barbarian worlds; [1001 Days] "The expansion of the empire by the first Augustus had come to an abrupt end in 9 CE when, in the course of stabilising Roman conquests in Germany, the Roman commander Publius Quinctilius Varus lost most of three legions at the Battle of the Teutoburg Forest, just north of the modern town of Osnabrück. It was a defeat that ranked in Roman imagination with the disaster at Cannae . . . Clear signs of his intentions have been discovered over the past twenty years in the excavations of a half-finished Roman town, at Waldgirmes, 60 miles east of the river; its central Forum was already constructed, complete with a gilded statue of the emperor on horseback. It was never finished because after the disaster Augustus gave up plans for more conquests, withdrew westwards and at his death left instructions that the empire should not be extended . . ."
