Battle of Dafei River

The Battle of Dafei River was fought in mid-670 between the forces of the Chinese Tang Dynasty and the Tibetan Empire, for control over the Tarim Basin (the "Western Regions" in Chinese parlance). The Chinese general, Xue Rengui, commanded a huge army of allegedly 100,000 men. He left his slower-moving baggage train and 20,000 soldiers under Guo Daifeng behind and advanced with the rest to Kokonur Lake. The Tibetans attacked and captured the Chinese baggage train, and proceeded to destroy Xue's own army at the Dafei River 大非川. In the aftermath of the battle, Chinese control over the Tarim basin collapsed.
