In summer 551, Hou was again aiding Ren, taking Xiao Daqi with him as hostage. Initially, with Hou backing him, Ren took the important city of Jiangxia (江夏, in modern Wuhan, Hubei), and Hou next approached Xiao Yi's headquarters at Jiangling (江陵, in modern Jingzhou, Hubei). However, Hou's forces then became bogged down while trying to siege Baling (巴陵, in modern Yueyang, Hunan), with Xiao Yi's general Wang Sengbian successfully defending Baling. Soon, Hou's food supplies ran out, and his forces collapsed. Ren was captured, and two other key generals, Song Zixian () and Ding He () were killed. Hou fled back to Jiankang.
