At this time, Emperor Yang was sieging Liaodong (遼東, in modern Liaoyang, Liaoning), and had nearly captured it from Goguryeo forces when news of Yang Xuangan's rebellion arrived. Yang Xuangan's associate Husi Zheng (斛斯政) surrendered to Goguryeo, and Emperor Yang retreated at night. Also around the same time, Wei Wensheng (衛文昇), the official Emperor Yang left in charge of Chang'an, came to Luoyang's aid with his troops, and Lai also arrived. Further, the forward forces returning from the Goguryeo front, under the command of Yuwen Shu and Qutu Tong, soon arrived as well, and while Yang Xuangan attempted to prevent them from crossing the Yellow River, attacks from Fan prevented Yang Xuangan from being able to cut Qutu and Yuwen off at the Yellow River, allowing them to cross. Yang Xuangan was soon losing battles, and under the suggestion of Li Zixiong (李子雄) and Li Mi, he decided to falsely declare that Yuan Hongsi (元弘嗣), the general in command at Honghua (弘化, in modern Qingyang, Gansu), was joining his cause, and that he was going to meet with Yuan.
