《资治通鉴·汉纪》970丨袁绍暗杀吕布，为何会失败？

Summary

This 芮淇讲透资治通鉴 episode backfills the northern late-Han branch before Hanji 971 and the later Yanzhou-Lü Bu sequence. It follows 袁绍 through the 魏郡 soldier revolt, the 黑山军 attack on 邺城, 陶生’s protection of Yuan Shao’s family, and Yuan Shao’s retaliatory campaigns against 余毒 and 张燕.

The core episode explains why the 袁绍刺吕布未遂 fails. Yuan Shao and 吕布 temporarily cooperate against Zhang Yan, but the relationship collapses over Lü Bu’s violent retinue and mutual insecurity; Yuan Shao then wraps a killing plan in appointment and escort language, while Lü Bu survives by detecting the escort threat, leaving sound in the tent, and escaping through a prepared passage before going again to 张杨.

Key Claims

• 袁绍 is at Boluojin when 魏郡 soldiers revolt and connect with 余毒’s 黑山军 forces.
• The rebels attack 邺城, kill the Wei commandery administrator, and frighten Yuan Shao’s followers because many families are inside the city.
• 陶生, a Black Mountain-linked commander and former Neihuang minor official, shuts the western gate, protects Yuan Shao’s household and state officials’ families, and escorts them to Chiqiu.
• Yuan Shao rewards Tao Sheng as Jianyi zhonglangjiang after the family rescue, then shifts toward revenge against the Black Mountain forces.
• Yuan Shao attacks 余毒 at Luchang Mountain around Zhaoge, breaks his force after five days, kills Yu Du and many followers, and continues north against multiple mountain leaders.
• Yuan Shao then fights 张燕 in the Changshan field, where Zhang Yan has tens of thousands of strong troops and thousands of horses, with Xiongnu and Wuhuan elements also in the field.
• 吕布 joins Yuan Shao against Zhang Yan, and the joint campaign lasts more than ten days before both sides withdraw exhausted.
• The alliance quickly destabilizes because Yuan Shao dislikes the violent conduct of Lü Bu’s soldiers, while Lü Bu reads Yuan Shao’s hostility and no longer wants to stay under him.
• Yuan Shao uses an imperial-style appointment and armed escort to create an assassination opening against Lü Bu, making the episode a late-Han case of 礼遇包装式清除 and 刺杀接近凭证.
• Lü Bu detects that the escort is suspicious, has people keep zither music sounding in his tent, and leaves through a pre-dug passage before the armed men destroy the bed and tent.
• Yuan Shao’s response after learning Lü Bu is alive is defensive fear: he closes the city gates against possible retaliation.
• Lü Bu survives the failed attempt and again attaches himself to 张杨, setting up the later route through Zhang Miao and Yanzhou.
• The closing preview introduces 曹嵩 leaving Langya toward 兖州 under the reception of 应劭, directly bridging to 曹嵩遇害 in Hanji 971.

Key Quotes

“是该回去了.” - Lü Bu’s banquet reply after Yuan Shao hints at Luoyang peonies.

“谁敢杀掉曹操父亲全家?” - the closing hook for the next Cao Song episode.

Connections

• Hanji 971 - direct sequel on 曹嵩遇害 after this episode’s closing preview.
• 袁绍, 吕布, 张燕, 黑山军, 余毒, and 陶生 - main northern military and alliance field.
• 魏郡, 邺城, 张杨, 公孙瓒, Xiongnu, and Wuhuan - place, patron, rival, and frontier-force context.
• 袁绍刺吕布未遂, 礼遇包装式清除, 刺杀接近凭证, 临危欺敌求生, 利益结构式联盟脆弱性, and 私交信任的政治脆弱性 - interpretive frames for the failed assassination and collapsed alliance.

Contradictions

• No settled contradiction found. The episode backfills the reason Lü Bu leaves Yuan Shao before Hanji 974’s Zhang Miao oath-and-Yanzhou entry branch.
• Source-scope caution: the zither, Guangling San, tunnel, and weapon-slashing details are preserved as this episode’s narrative account of the failed assassination, not generalized proof of Lü Bu’s long-term strategic reliability.
