郭子仪
The Tibetans attacked again in 765, when the Tiele jiedushi Pugu Huai'en sent false messages to Trisong Detsen, the emperor of Tibet, stating that Guo Ziyi had died. The Tibetan emperor was eager to avenge his earlier defeats, and dispatched a large force to attack Tang China again. Various Uyghur chieftains, also believing that Guo was dead, joined force with the Tibetans. The Tibetan force was recorded as more than 30,000 (including a few thousand Uyghurs), almost the entire Tibetan military at the time. However Pugu died on 27 September, and his army defected to the Tang.
