In 102 CE Ban Chao was retired as Protector General of the Western Regions due to age and ill health, and returned to the capital Luoyang at the age of 70, but the following month died there in the 9th month of the 14th Yongyuan year (30 Sept. to 28 Oct. 102). See: "Hou Hanshu", chap 77 (sometimes given as chap. 107). Following his death, the power of the Xiongnu in the Western Territories increased again, and subsequent Chinese emperors did not reach so far to the west again until the Tang Dynasty.
