《资治通鉴·周纪》16丨孙膑庞涓恩怨纠葛 桂陵之战

Summary

This 芮淇讲透资治通鉴 episode covers the 353 BCE cluster under 周显王: 齐国 rescues 赵国 from 魏国, 韩国 attacks the eastern Zhou polity, and 楚国 appoints 昭奚恤 as chancellor. Its central contribution is the 孙膑 branch: betrayal by 庞涓, rescue into Qi, 田忌赛马 as resource reallocation, and 围魏救赵 at 桂陵之战.

Key Claims

  • In 353 BCE, the source presents three notices: Qi saves Zhao and introduces the Sun Bin-Pang Juan story, Han attacks the eastern Zhou government, and Chu appoints Zhao Xixu as chancellor.
  • 孙膑 and 庞涓 are described as fellow students under 鬼谷子, but Pang Juan later tricks Sun Bin into coming to 魏国 and has him punished by mutilation and facial tattooing.
  • The episode uses Sun Bin’s survival to frame hope and resilience, arguing that suffering does not automatically destroy strategic agency.
  • A Qi envoy secretly brings Sun Bin to Qi, where 田忌 treats him as a guest.
  • 田忌赛马 shows Sun Bin’s preference for reallocating uneven resources: accept one losing matchup to create two winning ones.
  • 齐威王 asks Sun Bin how to break a stalemate between equally strong armies; Sun Bin answers with a 诱敌离位 pattern that uses a small exposed force to draw the enemy out before a prepared side attack.
  • The 1972 Yinqueshan find of 《孙膑兵法》 is used to support the distinction between Sun Bin, Sunzi, and their associated military texts.
  • When Qi decides to aid Zhao, Qi Wei Wang first wants Sun Bin as commander, but Sun Bin says his punishment and disability make it hard to establish immediate army prestige; Tian Ji is therefore commander and Sun Bin serves as military adviser.
  • Sun Bin rejects a direct march to Zhao and proposes attacking 大梁, the place Wei must rescue, while Wei’s forces are away besieging 邯郸.
  • The source presents the resulting 桂陵之战 as the practical demonstration of 围魏救赵: move pressure to the enemy’s vital point, force its army to change direction, and then ambush it.
  • The Han attack on Eastern Zhou shows how far 周王室 authority and territory have declined, with the old royal domain split into eastern and western Zhou polities.
  • The Chu chancellor notice lets the host explain why 司马光 often pays attention to chief ministers: Song literati politics could imagine important state work as something shared by emperor and scholar-officials rather than monopolized by the ruler.
  • 江乙 uses parables against Zhao Xixu, showing how apparently sound political language can become political weaponization.

Key Quotes

“批亢捣虚、形格势禁” - the source’s compact phrase for striking where the enemy must respond.

“围魏救赵” - the strategic label the episode unpacks through Qi’s attack on Daliang.
