司马卬 / Sima Ang

司马卬 / Sima Ang enters the wiki through Qinji 136 as a Zhao-side commander attempting to move south across the Yellow River toward 关中. The episode treats his movement as a competitive threat to 刘邦’s westward mission.

Liu Bang responds by attacking around Pingyin and cutting the crossing route. In the source’s interpretation, the point is not only operational security but credit control under 怀王之约: if another commander enters Guanzhong first, Liu Bang’s promised reward route is endangered.

Sima Ang therefore marks the competitive side of anti-Qin coalition warfare. Even while multiple forces oppose Qin, their routes and prizes can conflict, keeping 反秦阵营诸侯化分裂 active inside the shared campaign.
