《资治通鉴·周纪》20丨庞涓死此树下

Summary

This 芮淇讲透资治通鉴 episode completes the 马陵之战 arc from setup to outcome. 孙膑 uses 减灶诱敌 to make 庞涓 believe the 齐国 army is deserting, luring him into a light-force rapid pursuit. At Maling, Pang Juan triggers a prepared night ambush and kills himself; Qi then breaks the 魏国 army and captures 太子申, turning the battle into a major marker of Wei decline and a prelude to 田忌’s court danger.

Key Claims

• 孙膑 orders Qi’s invading army to leave ten wan stoves on the first day, five wan on the second, and two wan on the third, creating the appearance that Qi soldiers are fleeing.
• The episode explains the military logic of the stove count: cooking infrastructure can become a rough proxy for troop numbers, so abandoned stoves can mislead a pursuing commander.
• The immediate threat to Qi is 庞涓’s returning force, not 太子申’s force from 大梁, so Sun Bin designs the deception specifically for Pang Juan.
• Pang Juan should remember Sun Bin’s ability from 桂陵之战, but his desire to erase humiliation and win credit makes him treat the decreasing stoves as proof of Qi weakness.
• Pang Juan shifts from asking how to defeat Qi to asking how to catch Qi before it “runs away,” turning ambition into forced-march risk.
• He repeats the risky Guiling pattern by leaving the slow main force behind and pursuing with a smaller mobile force at doubled pace.
• Sun Bin chooses Maling, writes “庞涓死此树下” on a stripped tree, places crossbowmen along the road, and orders them to shoot when they see firelight.
• The episode says 《孙膑兵法》 gives the ambush a more concrete field-engineering layer, with chariots serving as walls and caltrops as a moat.
• Pang Juan reaches Maling at night, lights a torch to read the tree inscription, falls into the volley, recognizes the trap, and kills himself.
• Qi follows the disruption by attacking, breaking Wei’s army, and capturing 太子申.
• The host treats the story as partly dramatized but still narratively and strategically important.
• The episode locates the traditional battlefield near today’s Beimaling area of Dazhangjia Town, Shen County, Liaocheng, Shandong, while keeping that location claim source-scoped.
• After the defeat, Wei’s army and state power are described as badly damaged, while Tian Ji’s victorious return threatens 成侯邹忌’s relative standing in Qi.

Key Quotes

“庞涓死此树下” - the inscription Sun Bin has written at the ambush site.

“倍日并行逐之” - the phrase used for Pang Juan’s urgent doubled-pace pursuit.

Contradictions

• No direct contradiction found with existing wiki pages. The source completes the 马陵之战 page that Zhouji 18 previewed and Zhouji 19 developed as campaign setup.
• The source itself flags that the “庞涓死此树下” scene has some dramatized quality, so the wiki records the episode’s narrative without treating every dramatic detail as independently settled.
• The current-location claim near Shen County and Liaocheng is kept source-scoped; this ingest does not create separate location pages from a single brief note.
• The transcript uses “斧” for the cooking implement in the stove explanation; the wiki keeps the tactical point and does not create a separate equipment node from that likely transcription issue.
