the turmoil provided Emperor Xian with an excuse to ask Li Jue and Guo Si to let him go back to Luoyang, under the provisions that Li Jue could have Chang'an while Guo Si and other generals could follow the emperor to the dilapidated Luoyang. Jia Xu brought the two an imperial edict, and requested a truce between Li Jue and Guo Si, and the duo temporarily ceased fire upon Jia Xu's persuasion. Downfall After Jia Xu and Zhang Ji pleaded Li Jue and Guo Si to stop fighting, Guo Si started to move eastward with the emperor. However, on the journey to Luoyang, there were internal disputes, providing general Yang Feng with an opportunity to rescue the emperor. Aided by Dong Cheng and Xu Huang, Yang Feng defeated Guo Si and seized Emperor Xian. Guo Si returned to Li Jue and convinced the latter to make a last-ditch effort to recapture the emperor. When they caught up with the imperial train, Li Jue and Guo Si were defeated by Yang Feng, who had gained support from the White Wave Bandits. However, Yang Feng and the imperial retinue were running out of food, to the point that some court officials had to dig tree roots out from the earth as food. Thus, Emperor Xian sent emissaries to the various warlords, still nominal vassals of his, asking for help; however only a few of them replied with actual assistance. Zhang Yang, one of the warlords who received the edict, quickly sent his staff to support the emperor with supplies, and the forces of Li Jue and Guo Si were defeated in a decisive battle. Guo Si retreated to Mei County thereafter, and was later murdered by one of his commanders, who brought his remaining troops to Li Jue in Chang'an. In the April of 198, the warlord who now controlled the emperor, Cao Cao, sent envoys to incite the western warlords to attack Chang'an, Li Jue's home base. One of Li Jue's subordinates, Duan Wei (段煨), mutinied and killed Li Jue along with his family in the summer of 198. Duan Wei sent Li Jue's head to Xu city (as a sign of his submission to Cao Cao).
