裴度
In winter 815, assassins killed the chancellor Wu Yuanheng, who had been in charge of the campaign against Wu Yuanji; on the same morning, assassins tried to kill Pei as well, injuring Pei's head and causing Pei to fall into a ditch, but Pei's head was protected by a thick hat, allowing him to survive the attack. There was suggestions by some officials that Pei should be removed from office to appease Wu Yuanji's allies Wang Chengzong the military governor of Chengde Circuit (成德, headquartered in modern Shijiazhuang, Hebei) and Li Shidao the military governor of Pinglu Circuit (平盧, headquartered in modern Tai'an, Shandong). Emperor Xianzong rejected such talk, stating, "If I remove Pei Du from office, it will fulfill the desires of the treacherous, and the imperial government will no longer have any authority. My having Pei Du is sufficient to destroy the two bandits." He made Pei "Zhongshu Shilang" (), the deputy head of the legislative bureau, as well as "de facto" chancellor with the title "Tong Zhongshu Menxia Pingzhangshi" (). Subsequently, when Pei pointed out that then-overall commander of the campaign against Wu Yuanji, Yan Shou (), was incompetent, Emperor Xianzong made Han Hong the military governor of Xuanwu Circuit (宣武, headquartered in modern Kaifeng, Henan) overall commander instead.
