Xiao Yi sent Wang further east to put pressure on Hou, who by that point had retreated back to Jiankang. By fall 551, Wang had, in conjunction with another key general, Chen Baxian, who had advanced north from Guang Province (廣州, modern Guangdong), captured Jiang Province. Hou, believing that his days might be numbered, first deposed and killed Emperor Jianwen and replaced him with Xiao Dong the Prince of Yuzhang, the grandson of Emperor Wu's first crown prince Xiao Tong (who was also Xiao Yu's and Xiao Cha's father), and then forced Xiao Dong to yield the throne to him, establishing a state of Han. Upon the spread of news of Emperor Jianwen's death, Xiao Yi's generals requested that he take imperial title, but he refused.
