Sizhong to prepare for such an operation. (It is unclear, however, whether such an operation was actually ever launched.) In spring 843, Li Sizhong went to Chang'an to again pay homage to Emperor Wuzong. Believing that the Tang border generals were suspicious of him, he requested that he, his brothers, as well as his ally, the noble Ai Hongshun (愛弘順), all be transferred to Chang'an. Emperor Wuzong agreed. Subsequently, the Guiyi Army was disbanded, with the Huigu soldiers being dispersed to various circuits. That was the last reference to Li Sizhong in Chinese historical records, and the date of his death is unknown. Notes and references New Book of Tang, vol. 217, part 2. Zizhi Tongjian, vols, 246, 247.
