When Liu Bei heard of Liu Cong's surrender, he led his followers (both troops and civilians) on an exodus southward to Xiakou, engaging Cao Cao's forces in a brief skirmish at the Battle of Changban along the way. While in Xiakou, Liu Bei sent Zhuge Liang to follow Lu Su to Jiangdong to discuss the formation of an alliance between him and Sun Quan.
