《资治通鉴·汉纪》1023丨揭秘曹操与张绣的兵法博弈

Summary

This 芮淇讲透资治通鉴 episode backfills the post-Wancheng, pre-Guandu pursuit branch before Hanji 1024 and before Zhang Xiu’s later renewed submission in Hanji 1035. 袁绍’s capital-relocation idea and 田丰’s rejected advice to strike 许都 push 曹操 into withdrawing from the 穰城 front, while 张绣 and 刘表 try to block his retreat at 安重. The episode’s durable synthesis is 归师勿遏式追击风险: a retreating force can become more dangerous when route pressure, morale, commander presence, and ambush preparation align.

Key Claims

• Yuan Shao dislikes imperial edicts that do not favor him and proposes moving the emperor’s capital away from Xudu toward a place rendered in the transcript as “眷城”; Cao Cao reads the proposal as a bid to bring the emperor closer to Yuan Shao’s sphere and refuses.
• Tian Feng urges Yuan Shao to attack Xudu and receive Emperor Xian so Yuan can command the realm through the court, but Yuan Shao does not adopt the advice.
• A Yuan-side soldier defects to Cao Cao’s camp and reports Tian Feng’s advice, leading Cao Cao to withdraw quickly from the Rangcheng front toward Xudu.
• In May, Zhang Xiu pursues Cao Cao, Liu Biao sends forces to support Zhang Xiu, and the two sides use difficult terrain at Anzhong to block Cao Cao’s return route.
• Cao Cao opens a risky narrow path by night, makes it look as if he is escaping, draws Zhang Xiu and Liu Biao’s combined force out in pursuit, and defeats them with infantry and cavalry ambushes from front and rear.
• Cao Cao explains the victory by saying the enemy tried to press him into desperation; the host connects this to 《孙子兵法》 principles about returning armies and death-ground resolve.
• Jia Xu first warns Zhang Xiu not to pursue Cao Cao, then after Zhang Xiu’s defeat advises an immediate second pursuit; he explains the two judgments by tracking Cao Cao’s rear emergency, personal rear-guard command, later light-cavalry departure, and weaker replacement rear guard.

Key Quotes

“归师勿遏” - Sunzi principle used to explain why blocking a returning army can provoke desperate fighting.

“置之死地而后生” - death-ground principle used to frame Cao Cao’s Anzhong counterstroke.

Connections

• 曹操, 张绣, 刘表, 贾诩, 安重, and 穰城 - core withdrawal, pursuit, terrain blockade, ambush, and second-pursuit sequence.
• 袁绍, 田丰, 许都, and 汉献帝 - court-relocation and missed attack-the-capital branch before Cao Cao’s withdrawal.
• 归师勿遏式追击风险, 死地战术前提, 诱敌离位, 战场信息控制, and 行势情战略评估 - conceptual frames for pursuit risk, forced resolve, false escape, and condition-sensitive command judgment.
• Hanji 1012, Hanji 1013, and Hanji 1035 - nearby Wancheng, aftermath, and later Zhang Xiu submission sequence.

Contradictions

• No settled contradiction found.
• This source qualifies a simple revenge or weakness reading of the post-Wancheng branch: Zhang Xiu and Liu Biao can create real tactical danger for Cao Cao, but Cao Cao can also turn blocked retreat into a trap; Jia Xu’s pursuit advice is condition-sensitive rather than a blanket rule against or for pursuit.
• Source-scope caution: the transcript’s place wording “眷城” and “壤县” is preserved as source-scoped. The wiki links the clear Nanyang/Rang branch to existing 穰城 but does not create a separate page from the uncertain capital-relocation spelling.
