《资治通鉴·汉纪》1024丨勇冠三军吕布，为何始终一事无成？

Summary

This 芮淇讲透资治通鉴 episode supplies the immediate pre-Hanji 1025 decision field: 吕布 cooperates again with 袁术, sends 高顺 and 张辽 against 刘备, faces 曹操’s advance toward 下邳, and abandons 陈宫’s inner-outer attrition plan after household warning. The episode uses desire and focus as the interpretive lens, arguing that force and ambition become destructive when not governed by self-command. Its durable contribution is that Lü Bu’s failure is not lack of military assets, but inability to convert advisers, allies, subordinates, and timing into stable initiative.

Key Claims

• Desire is presented as double-edged: it can motivate action, but without rational self-command it becomes greed, confusion, and scattered attention.
• The episode links focus with subtraction, using the Daoist line “少则得，多则惑” to argue that disciplined desire gives a person direction while too many aims produce disorder.
• In 198 CE, Lü Bu again connects with Yuan Shu and sends Gao Shun and Zhang Liao to attack Liu Bei at 小沛.
• Cao Cao sends 夏侯惇 to relieve Liu Bei, but Xiahou Dun is defeated; Gao Shun captures Pei and Liu Bei’s wife and children.
• 荀攸 urges Cao Cao to attack Lü Bu before Lü Bu’s courage and Yuan Shu’s support can form a larger Huai-Si threat.
• Taishan-associated leaders 张霸, 孙观, 吴敦, 尹礼, and 昌豨 attach themselves to Lü Bu, increasing the urgency of Cao Cao’s move.
• Chen Gong advises Lü Bu to strike Cao Cao while Cao’s army is still arriving and tired; Lü Bu refuses, saying he will wait and use the 泗水 against Cao Cao.
• After Cao Cao reaches Xiapi, 陈登 leads the vanguard, Lü Bu loses repeated fights, withdraws into the city, and becomes fearful enough to consider surrender after Cao sends a letter.
• Chen Gong then proposes that Lü Bu lead infantry and cavalry outside the city while Chen Gong and Gao Shun defend inside, forcing Cao Cao either to expose his rear or exhaust supplies within a month.
• Lü Bu initially accepts the plan, but his wife warns that Chen Gong and Gao Shun do not cooperate well and that Chen Gong once left Cao Cao despite Cao’s good treatment; Lü Bu abandons the plan.
• Lü Bu secretly sends 许汜 and 王楷 to ask Yuan Shu for rescue; Yuan Shu first complains about the unfinished marriage alliance, then prepares troops after they argue that Lü Bu’s fall will endanger Yuan Shu.
• The episode closes before the final Xiapi outcome, making this source a pre-collapse analysis rather than the execution-and-aftermath account supplied by Hanji 1025 and Hanji 1026.

Key Quotes

“少则得，多则惑” - Daoist line used to connect focused attention with governed desire.

“且听明天分解” - closing marker that the episode stops before the final Xiapi resolution.

Connections

• Hanji 1025 and Hanji 1026 - continuation of the Xiapi siege, internal defection, surrender, and execution aftermath.
• 吕布, 曹操, 刘备, 袁术, 陈宫, 高顺, 张辽, 夏侯惇, 荀攸, 陈登, 下邳, 小沛, and 泗水 - central actors and places in the campaign setup.
• 张霸, 孙观, 吴敦, 尹礼, and 昌豨 - Taishan-linked force field that makes Lü Bu’s camp a wider regional threat.
• 许汜 and 王楷 - envoys used to reopen Yuan Shu’s rescue channel.
• 轻于去就, 饥附饱扬, 战争成本与速决纪律, 长期成事纪律, 吕布集团派系平衡, 君臣反馈失灵, 行势情战略评估, and 可信武力展示威慑 - conceptual frames for unstable affiliation, supply-timing discipline, self-command, command trust, and prior successful force display.

Contradictions

• No settled contradiction found. The source qualifies single-cause readings of Lü Bu’s fall by moving the failure earlier than the alcohol-ban and water-siege triggers: his initiative is already weakened by rejected advice, abandoned plans, unstable trust, and dependence on Yuan Shu’s rescue.
• Source-scope caution: the episode’s philosophical frame reads Lü Bu through desire, focus, humility, and mental order; those are interpretive judgments, not independent proof of inner motive.
