Huan Yi

Huan Yi was a general of the state of Qin in the late Warring States period (5th century – 221 BCE). Background General Pang Nuan of Zhao occupied several towns of the state of Yan in 236 BCE, whereupon Yan asked the state of Qin for help. Huan Yi, Yang Duanhe, and Wang Jian commanded the relief campaign against Zhao and took its towns Ye (today's Linzhang, Hebei) and Anyang (Hebei), as well as Eyu (Heshun, Shanxi), and Liaoyang (Zuoquan, Shanxi). In 236 BC, the Qin generals Huan Yi and Wang Jian seize nine cities in the Yecheng region. In 234 BC, Huan Yi attacked Pingyang (Linfen, Shanxi) and Wucheng (Cixian, Hebei), killed general Hu Zhe and massacred 100,000 troops of Zhao. He then left Shangdang, passed the Taihang Ridge and invaded Zhao by taking Chili and Yi'an (Gaocheng, Hebei). Zhao thereupon laid the supreme command in the hands of Li Mu, who defeated Huan Yi in the battle of Fei (Jinxian, Hebei).
