《资治通鉴·周纪》51丨 楚怀王：秦小儿看舅舅如何灭了你！

Summary

This 芮淇讲透资治通鉴 episode continues the 张仪 deception of 楚怀王 from Zhouji 50. It explains why Chu Huaiwang accepted the six-hundred-li 商於 promise, then follows his angry attack on 秦国 through 丹阳之战, the loss of 汉中, the renewed drive through 武关 and Shangyu, and defeat near 蓝田之战. The episode’s governing lesson is 因怒兴师: a ruler who turns humiliation into war can lose both strategy and recovery room.

Key Claims

• The episode answers the previous episode’s question: Chu Huaiwang was experienced, powerful, and not old, but the scale of Zhang Yi’s promised six hundred li made the offer hard to resist.
• Chu Huaiwang also misread Qin’s credibility because 秦惠文王 was a great-power ruler and Zhang Yi was Qin’s chief minister; he forgot the precedent of 商鞅 deceiving 公子卬 / 公子昂.
• 陈枕’s warning had little effect because Zhang Yi had already influenced the 楚国 court through gifts to ministers and favored palace figures.
• The source says Zhang Yi also joined in slandering 屈原, pushing a committed anti-Qin voice out of court and making Chen Zhen more isolated.
• In 312 BCE, Chu Huaiwang responds to the six-li reversal by sending Chu troops north from Danyang toward Wuguan instead of containing the loss.
• Qin defeats Chu at 丹阳之战, kills eighty thousand Chu armored soldiers, captures commander 屈匄 and many high-ranking nobles, and takes 汉中.
• Chu Huaiwang then mobilizes the whole country again; the episode argues that he should have focused on recovering newly lost Hanzhong, but instead remained fixated on the promised Shangyu land.
• Qin retreats through Wuguan and Shangyu, lures Chu deep toward Xianyang, and counterattacks near 蓝田之战 after Chu has become isolated and supply-stretched.
• 韩国 and 魏国 exploit the moment by threatening the Chu capital region and moving toward Chu’s rear, forcing Chu Huaiwang to panic, withdraw, and cede cities for peace.
• The episode uses 《孙子兵法》 to frame the result: rulers should not raise armies from anger, and generals should not fight from resentment.

Key Quotes

“君不可以怒而兴师” - the episode’s Sunzi frame for Chu Huaiwang’s decision.

“亡国不可以复存，死者不可以复生” - the irreversible-cost warning used to close the episode’s evaluation.

Connections

• 楚怀王, 陈枕, 屈原, 楚国, and 君臣反馈失灵 - the target court where warning voices lose weight before and after the deception.
• 张仪, 秦惠文王, 秦国, 商於, 未验地先断交陷阱, 连横, and 纵横家外交 - the Qin-side trap and alliance-separation background.
• 丹阳之战, 屈匄, 汉中, 武关, and 蓝田之战 - battlefield and geography branch created by the sequel.
• 因怒兴师, 《孙子兵法》, 秦国东进压力, and 急行军作战风险 - governance and military concepts that make the campaign readable.
• 韩国, 魏国, and 燕国 - states in the closing frame: Han and Wei exploit Chu’s exposure, while Yan prince Ji Ping is left as the next-episode hook.

Contradictions

• No direct contradiction found in existing wiki claims.
• This source extends Zhouji 50 rather than replacing it: the prior page ends at Chu’s angry attack, while this page records the military consequences in 312 BCE.
• The source strengthens 君臣反馈失灵 by adding a court-capture layer: Chen Zhen is not merely ignored once, but isolated after Zhang Yi’s prior influence over Chu elites and the removal of Qu Yuan.
