曹无伤 / Cao Wushang
曹无伤 / Cao Wushang enters the wiki through Qinji 129-1 as 刘邦’s left sima during early anti-Qin fighting. After Liu Bang attacks Xue County and the Sishui commandery governor Zhuang retreats, Cao Wushang captures and kills him.
The host flags Cao Wushang’s later narrative importance by noting that he is the same figure who nearly gets Liu Bang killed at the 鸿门宴. This page keeps that as a forward link: in this source, his concrete action is still a successful battlefield capture on Liu Bang’s side.
