was then issued him cancelling that summon. Instead, he set up his base at Zheqi (赭圻, in modern Wuhu, Anhui) and monitored the situation at Jiankang remotely. In 365, Murong Ke attacked Luoyang, and initially, Huan and Sima Yu were planning a counterattack to relieve Luoyang, but the plan was cancelled after Emperor Ai died in spring 365. Soon, Luoyang fell. Late in 365, the Jin general Sima Xun, the governor of Liang Province (梁州, modern southern Shaanxi), who had participated in many campaigns, rebelled, and Huan commissioned one of his generals, Zhu Xu, to attack Sima. Sima was soon captured and killed. After Murong Ke died in 367, Huan began to plan to attack Former Yan, whose regime was now largely in the hands of Murong Wei's granduncle Murong Ping the Prince of Shangyong, regarded as incompetent and corrupt, and Murong Wei's mother Empress Dowager Kezuhun. In 369, he launched the campaign, in conjunction with Chi Chao's father Chi Yin (郗愔), his brother Huan Chong, and Yuan Zhen, although he soon seized Chi Yin's troops and put them under his own command. Despite Chi Chao's advice that he head directly for Former Yan's capital Yecheng, Huan proceeded slowly, defeating Former Yan's troops repeatedly but taking three months to reach the Yellow River, stoppinging Fangtou (枋頭, in modern Hebi, Henan) -- and again hesitated there at crossing the Yellow River and attacking Yecheng, not far away. Murong Wei and Empress Dowager Kezuhun were panicking and planning to flee back to the old capital Helong (和龍, in modern Jinzhou, Liaoning), but Murong Wei's uncle Murong Chui the Prince of Wu offered to make one last attempt to resist Huan. Murong Chui and his brother Murong De engaged Huan, dealing him minor losses. Meanwhile, the Jin army's food supply was running out (as a supply plan that Huan put Yuan in charge of was failing in light of the failure to build a canal quickly). Huan began to withdraw, and Murong Chui and Murong De set up a trap for Huan's army, nearly annihilating it. Soon, Former Qin forces, from which Former Yan had sought assistance from, also arrived, and Huan was dealt another major defeat. Huan, humiliated at the greatest defeat in his career, deflected blame by accusing Yuan of being unable to supply food and ordered that Yuan be demoted to commoner status. Yuan, instead of submitting, occupied Shouchun (壽春,
