班超
After Dou sent 2,000 cavalry to attack the Northern Xiongnu base at Hami, he was followed by the initiative of the general Ban Chao (d. 102 CE), who earlier installed a new king of Kashgar as a Han ally. When this king turned against him and enlisted the aid of Sogdiana in 84 CE, Ban Chao arranged an alliance with the Kushan Empire (of modern North India, Pakistan, Afghanistan, and Tajikistan), which put political pressure on Sogdiana to back down; Ban later assassinated King Zhong of Kashgar. Since Kushan provided aid to Ban Chao in quelling Turpan and sent tribute and hostages to Han, its ruler Vima Kadphises (r. c. 90 – c. 100 CE) requested a Chinese princess bride; when this was rejected in 90 CE, Kushan marched 70,000 troops to Wakhan against Ban Chao. Ban used scorched earth tactics against Kushan, forcing them to request food supplies from Kucha. When Kushan messengers were intercepted by Ban, Kushan was forced to withdraw. In 91 CE, Ban was appointed as Protector General of the Western Regions, an office he filled until 101 CE.
