Summary
This practical chapter covers army movement through different terrain types and the art of reading signals. Sun Tzu provides specific guidance for mountains, rivers, marshes, and open ground—each requiring different approaches. More importantly, the chapter catalogs behavioral signals that reveal enemy intentions. Dust patterns indicate troop movements. Birds rising suddenly show hidden forces. Humble words accompanied by increased preparations signal impending attack. Many small signs, properly read, reveal what the enemy is planning. The chapter emphasizes that discipline is a partnership: 'If soldiers are punished before they have grown attached to you, they will not prove submissive.' Effective leadership balances authority with relationship.
