《资治通鉴·汉纪》1117丨周瑜妙计软禁刘备，孙权为何不采纳？

Summary

This 芮淇讲透资治通鉴 episode reconstructs a post-赤壁之战 choice inside the Sun-Liu coalition. 周瑜 and 吕范 reportedly urge 孙权 to detain 刘备, separate him from 关羽 and 张飞, and prevent an ambitious guest from turning borrowed territory into independent power; Sun Quan declines because 曹操 remains the more immediate threat and the Liu group is still needed in the anti-Cao front.

The episode then supplies the strategic prequel to Hanji 1118. Zhou Yu proposes a westward campaign through 益州 and 张鲁’s Hanzhong, a connection with 马超, and a later return toward Xiangyang against Cao Cao. Illness ends the plan, and Zhou Yu recommends 鲁肃 before dying, completing the antecedent to Lu Su’s command succession and Sun Quan’s later support for Liu Bei’s Jingzhou foothold.

Key Claims

• After Liu Qi’s death and the absorption of his followers, Liu Bei travels from Gong’an to Jingkou and asks Sun Quan for broader control in Jingzhou because his existing territory cannot contain the enlarged force.
• Zhou Yu judges that Liu Bei will not remain subordinate while Guan Yu and Zhang Fei stay under his direct influence, so he proposes comfortable detention in Wu Commandery and organizational separation of the three leaders.
• Lu Fan also advises detention, but Sun Quan rejects the proposal because Cao Cao remains the larger near-term threat and breaking with Liu Bei could trigger resistance from Guan Yu, Zhang Fei, and 诸葛亮.
• The source therefore presents Sun Quan’s choice as threat sequencing rather than blindness: accepting a future autonomous-rival risk preserves a coalition needed against the more urgent northern power.
• Liu Bei later says Zhuge Liang had warned him not to make the trip, marking the Jingkou visit as a consciously accepted personal and organizational risk.
• Zhou Yu’s westward plan links an attack into Yizhou, pressure on Zhang Lu, cooperation with Ma Chao, and a return toward Xiangyang into one multi-theater program against Cao Cao.
• When illness stops the expedition, Zhou Yu warns that both Cao Cao and Liu Bei remain dangerous and recommends Lu Su as loyal and careful enough to succeed him.
• The episode closes by presenting Zhou Yu as a commander with strategic reach, interpersonal restraint toward 程普, and cultivated musical judgment, while the claim that another twenty years would have changed history remains counterfactual.

Key Quotes

“蛟龙得云雨，终非池中物也。” - the episode’s image for the danger of giving Liu Bei territory while leaving his command group intact.

“鲁肃忠烈，临事不苟，可以代瑜。” - the episode’s rendering of Zhou Yu’s succession recommendation.

Connections

• 周瑜, 孙权, and 刘备 - proposed detention, rejected containment, and the dangerous-allied-guest problem.
• 关羽, 张飞, and 诸葛亮 - organizational capacity that makes detaining Liu Bei costly rather than decisive.
• 曹操 and 战略基地转移式联盟巩固 - the common enemy that makes continued partner empowerment preferable to immediate internal suppression.
• 益州, 张鲁, and 马超 - western components in Zhou Yu’s unfinished multi-theater strategy.
• 鲁肃 and Hanji 1118 - deathbed recommendation and the later command-succession outcome.
• 程普 - older commander whose eventual respect is used to illustrate Zhou Yu’s interpersonal restraint.

Contradictions

• No settled contradiction is recorded. Hanji 1117 supplies the containment proposal, threat hierarchy, westward-plan detail, and deathbed recommendation that Hanji 1118 treats mainly through their later consequences.
• Strategic qualification: the source’s shorthand around “借荆州,” jurisdiction, and Liu Bei’s request compresses a complicated postwar territorial settlement; it should not be read as an uncontested bilateral loan of one clearly bounded province.
• Motive qualification: Sun Quan’s rejection of detention is preserved as the episode’s explanation. It does not prove that fear of Cao Cao was the only consideration or that Guan Yu, Zhang Fei, and Zhuge Liang would necessarily have responded in the predicted way.
• Source-scope caution: the exact letters and dialogue, route distance and travel time, Cao Cao’s political pressure, Zhang Lu background, medical sequence, death location, family arrangements, Cheng Pu anecdote, musical story, and counterfactual twenty-year claim require comparison with underlying historical texts.
