Gao Shun
In 198, Lü Bu made peace with Yuan Shu again, and sent his general Gao Shun to attack Liu Bei at Xiaopei. Cao Cao sent Xiahou Dun with an army to reinforce Liu Bei, but they were still defeated by Gao Shun. Xiaopei fell to Lü Bu's forces in October 198 and Liu Bei escaped, but his wives were captured.
