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). No record of Huan Yi is found in the Shiji after his defeat at Feixia. However in the Zhan Guo Ce (a different historical source) it's mentioned that Huan Yi later died attacking Handan, the capital of Zhao, which was defended by
Li Mu in one of the last Qin-Zhao battles. == Identification with Fan Yuqi ==
