Battle of Ikh Bayan and the Yanran inscription

In 89 a Han army under Dou Xian, with Southern Xiongnu allies, routed the Northern Xiongnu at Mount Jiluo (the battle is also known as the Battle of Ikh Bayan), and on Mount Yanran in the Gobi he had a victory text by the historian Ban Gu carved in the rock. The campaigns of 89–91 ended the Northern Xiongnu state in Mongolia.

Weakened by famine and by a Xianbei attack in which their chanyu Youliu was killed (87), the Northern Xiongnu were attacked in 89 at the request of the Southern chanyu. Dou Xian, brother of the regent Empress Dowager Dou, led three columns — Han troops with Southern Xiongnu, Wuhuan and Qiang allies — out of the frontier forts. According to the Book of the Later Han, 13,000 Northern Xiongnu were killed and 200,000 people of 81 tribes surrendered. Dou Xian marched on to Mount Yanran and had a text composed by Ban Gu, a member of his staff, carved on a cliff; “to carve a stone on Yanran” became a Chinese byword for a great victory.

In 90–91 further attacks by the Han and the Southern Xiongnu drove the Northern chanyu from the Altai to the northwest, and his state in Mongolia came to an end. A northern chanyu still sent envoys to the Han in 104–105, and Northern Xiongnu remnants fought for the Western Regions until the 150s, while most of those who stayed on the steppe were absorbed by the Xianbei, the new masters of Mongolia.

The cliff with the inscription was noticed on 27 June 2001, and in 2016–2017 Mongolian and Chinese scholars identified on it the text preserved in the Book of the Later Han; it lies in the Delgerkhangai Mountains of Dundgovi Province, and about 220 of its 260 characters are legible. Where Mount Jiluo lay is not established (some reference works call the battle the Battle of Ikh Bayan); in English it is also called the Battle of the Altai Mountains, a name also given to Geng Kui’s victory of 91.
