Taking control of the province of Germania in 6 AD, Publius Quinctilius Varus quickly proved an unpopular administrator with the allied and neutral Germanic tribes. In September 9 AD, he began moving his army from the Weser River to its winter camps along the Rhine. Among the allied troops in his army was the Germanic leader Arminius. Angry over Varus' treatment of his people, Arminius secretly formed an alliance of Germanic tribes to strike at the Romans. Fabricating reports of uprisings, he directed Varus to move through the Teutoburg Forest to put them down. Leaving the army, Arminius joined the Germanic forces and began a series of attacks against Varus' men once the Romans had entered the forest. In a series of battles among the trees, the Germanic troops overwhelmed and ultimately destroyed three Roman legions. With his forces facing annihilation, Varus committed suicide. Though the Romans would later avenge the defeat, the battle effectively halted Roman expansion at the Rhine.
