Xiao Yi's older brother Xiao Guan () the Prince of Shaoling, at that time holding his troops at Jiangxia (江夏, in modern Wuhan, Hubei), considered trying to save Xiao Yu, but felt that he did not have enough strength to do so, and therefore sent letters to Xiao Yi, trying to persuade him to give up the siege on Changsha. Xiao Yi refused, and continued the siege. Soon, Changsha fell, and Wang executed Xiao Yu. It was only after this point that Xiao Yi acknowledged Emperor Wu's death. While he implicitly recognized Emperor Jianwen as the rightful emperor, he refused to recognize Emperor Jianwen's era name "Dabao" () and continued to use Emperor Wu's era name "Taiqing" (), and, citing the fact that Hou Jing was actually in control, did not recognize Emperor Jianwen's edicts. When Xiao Yi's younger brother Xiao Ji the Prince of Wuling, who was then controlling the modern Sichuan and Chongqing region, sent an army commanded by his heir apparent Xiao Yuanzhao () toward Jing Province, claiming to be willing to accept Xiao Yi's command in attacking Hou, Xiao Yi commissioned Xiao Yuanzhao as the governor of Xin Province (信州, modern eastern Chongqing) and ordered him to halt at Xin Province's capital Baidicheng and not to proceed any further.
