The Battle of Baideng (白登之戰) was a military conflict between Han China and the Xiongnu in 200 BC. In an alternate account, Grousset says that the Xiongnu invaded Chinese Shanxi and besieged Taiyuan. Gaozu broke the siege and chased the Xiongnu north, but was blockaded by them on the Baideng plateau near Datong in far northern Shanxi.
