This chapter uses water as a metaphor for warfare: evade enemy strength and strike weaknesses. Armies adjust tactics like water shifting course. War has no fixed formation; commanders who flexibly adapt to foes’ shifting situations earn the title of master strategist.
This passage introduces four ways to probe enemy intelligence: analyzing schemes, provoking movements, feigning deployments and small skirmishes. The supreme stratagem is invisible troop formations, hiding all plans and flexibly adapting tactics to endless shifting battlefield conditions.
Sun Tzu states hiding your battlefield forces foes to spread defenses thin everywhere. Troops weaken when passively guarding all fronts. Wu Zixu’s rotating border raids on Chu perfectly embody this logic, exhausting Chu’s scattered army and paving Wu’s final victory.
This article explains Sun Tzu’s tactic of feigning humility to inflate enemy arrogance. Modu Chanyu yielded treasures and his wife to lull Donghu, then crushed them. It also parallels Lu Xun’s flattering ploy that tricked arrogant Guan Yu into losing Jingzhou.
This article analyzes the Battle of Xiangfan through Sun Tzu’s strategies. Sima Yi urged Cao Cao to ally with Wu, luring Sun Quan with territory to attack Guan Yu’s rear. Arrogant Guan Yu ignored hidden threats, lost Jingzhou, embodying the cost of ignoring diplomatic and deceptive warfare principles.
Based on The Art of War, this article analyzes Guan Yu’s ruinous arrogance. Wu’s Lü Meng and Lu Xun used feigned weakness and flattering words to relax his vigilance. Guan Yu moved rear troops north, lost Jingzhou, and his defeat crippled Shu Han’s unification ambitions.
