司马错 / Sima Cuo
司马错 / Sima Cuo appears in 《资治通鉴·周纪》52丨 陈庄叛秦 端起碗吃饭放下碗骂娘 as the Qin strategist whose advice helps 秦惠文王 choose the 蜀国 campaign. The episode says 巴国 and Shu are fighting and both seek Qin’s help, creating an opening despite hard roads.
The source uses Sima Cuo as the decision hinge before 秦国 acquires 巴蜀. His advice leads to a campaign that gives Qin a major southwestern base, but it also creates the later governance problem in which 陈庄 can rebel from inside conquered Shu.
《资治通鉴·周纪》66丨中国历史上哪些帝王是被活活饿死的（1） adds a later military-office notice. In 295 BCE, Sima Cuo appears as Qin’s guowei attacking 魏国 at a place rendered as Xiangcheng or Xiangcheng-like in the source summary. The page therefore now records him as more than the earlier Ba-Shu strategist: he remains part of Qin’s continuing eastern military pressure.
《资治通鉴·周纪》77丨廉颇与蔺相如 史上最著名的一对“好基友” returns Sima Cuo to the southwest route. In the episode’s 280 BCE frame, 秦昭襄王 sends him with Longxi forces through 巴蜀 toward Chu’s Qianzhong region, an itinerary the host treats as unusually difficult because of distance, mountains, rivers, and plateau terrain. The source uses him to show that Qin’s power includes cross-regional logistics, not only famous commanders such as 白起.
