Delay fording swollen rivers; avoid precipitous, confined, tangled, or boggy terrain and instead lure the enemy into it or place it behind him.

By Sun Tzu, from L'Art de la guerre

Key Arguments

  • Waiting for subsiding waters prevents disaster during crossings.
  • Hazardous terrain degrades formations; avoiding it preserves cohesion.
  • Manipulating enemy movement into bad ground creates positional advantage and endangers his rear.
