司马梗 / Sima Geng

司马梗 / Sima Geng enters the wiki through 《资治通鉴·周纪》95丨长平之战后秦国为什么没有灭了赵国（1） as one of the 秦国 commanders used after the 长平之战. In the episode’s 《资治通鉴》 account, 白起 orders 王龁 toward 武安 and 皮牢, while Sima Geng leads another route toward 太原 and 上党郡.

His role is source-scoped and operational. The episode uses him to show that Qin’s post-Changping pressure was not merely a threat against 邯郸 in the abstract; it was a set of converging movements intended to strip 赵国 of surrounding positions before the capital became the likely next target.
