《资治通鉴·汉纪》1123丨他不上战场，如何立下显赫战功？

Summary

This 芮淇讲透资治通鉴 episode follows the aftermath of the 渭南之战. 曹操 accepts 杨秋’s surrender, leaves 夏侯渊 and 张既 to consolidate the west, and benefits from 杜畿’s stable 河东郡, whose grain supply and reported post-campaign surplus make rear-area governance part of battlefield capacity.

The second half turns to 法正, who remains underused by 刘璋 until his friend 张松 recommends him as envoy to 刘备. The source says Fa Zheng returns convinced of Liu Bei’s quality and joins Zhang Song in planning to bring Liu Bei into 益州, extending the earlier alliance pivot from diplomatic recommendation toward an internal transfer-of-power project.

Key Claims

• The episode presents Cao Cao’s victory as an interaction among political legitimacy, battlefield judgment, coalition division, and a logistics base rather than as front-line tactics alone.
• After Yang Qiu surrenders at Anding, Cao Cao restores his title and uses him to pacify his own followers, making local incorporation part of postwar consolidation.
• Zhang Ji’s conciliatory administration in the capital region is said to recall displaced people and rebuild settlements, while Xiahou Yuan remains at Chang’an for military control.
• Hedong does not join the wider western uprising, and Du Ji continues supplying Cao Cao’s army during the confrontation with Ma Chao.
• The reported surplus of more than two hundred thousand hu after Ma Chao’s defeat is used to argue that stable administration, production, storage, and transport can earn military merit without personal battlefield service.
• The episode gives Du Ji a biographical frame—early hardship, a filial reputation, legal-administrative ability, recommendation by 荀彧, later high office under 曹丕, and death during a river-vessel trial—but these details require direct textual corroboration.
• Fa Zheng is portrayed as a talented but underused official from Fufeng whose strategic judgment later drew comparison with 程昱 and 郭嘉.
• Zhang Song recommends Fa Zheng as Liu Zhang’s envoy; after meeting Liu Bei, Fa Zheng and Zhang Song begin planning to receive Liu Bei into Yizhou as its future ruler.

Key Quotes

“一曰道，二曰天，三曰地，四曰将，五曰法。” - the episode’s Art of War frame for treating warfare as a system rather than a battlefield event only.

“不上战场，也可以凭保障战争全局而建立显赫功勋。” - the supplied summary’s statement of Du Ji’s rear-area contribution.

Connections

• 渭南之战, 曹操, 马超, and 韩遂 - campaign aftermath and the episode’s system-level explanation of victory.
• 杜畿, 河东郡, and 分布式地方韧性 - local stability, production, storage, and military supply as rear-area war capacity.
• 杨秋, 夏侯渊, 张既, 安定郡, and 关中 - surrender incorporation and western consolidation after the campaign.
• 法正, 张松, 刘璋, 刘备, and 益州 - underused talent, envoy selection, and the emerging plan to transfer Yizhou’s allegiance.
• 谋士政权架构 and 毒士灰度谋略 - later frames for Fa Zheng’s tactical ability and morally ambiguous exercise of power.

Contradictions

• No settled contradiction is adopted. The Du Ji section extends the earlier Hedong defense-and-settlement sequence into the 211 CE Guanzhong campaign, while the Fa Zheng section supplies an earlier career and alignment layer for an adviser previously represented mainly by later tactical skill and revenge politics.
• Naming caution: the source says Du Ji died during a trial voyage on “陶河,” but the place or vessel wording is not normalized here without direct textual confirmation.
• Source-scope caution: Cao Cao’s deliberate rule mastery, the exact Yang Qiu and Zhang Ji settlement details, the reported grain surplus, Du Ji’s childhood and office chronology, Fa Zheng’s family pedigree and private motives, his initial feigned refusal, and Liu Bei’s personal charisma remain bounded to this popular-history summary unless corroborated.
