Definition
“Lessons of War” (Part Two) comprises strategic studies by Liu Ji and the recovered “Lost Art of War” by Sun Bin II. It synthesizes tactical methodologies, emphasizing the role of calculation, espionage, elite units, and the psychological dimensions of conflict. The chapter transitions from general leadership traits (Part One) to specific battlefield and strategic applications.
Why It Matters
This chapter emphasizes that warfare is a holistic system where calculation and psychology are as important as brute force; it teaches that the highest form of mastery is not the destruction of the enemy, but the “reduction of opposition” through superior preparation and adaptation.
Core Concepts
Foundations of Strategy (Liu Ji)
- Calculation First: Warfare must begin with assessment: relative leadership sagacity, enemy strength, terrain, and provisions.
- Conflict Avoidance: “Good warriors lessen opponents.” The goal is not destruction but minimizing opposition, often by using opponents to oppose opponents.
- Preparedness: Never forget danger during times of security; never forget chaos during times of order.
- Adaptation: Victory is attained through the genius of changing and adapting according to the opponent’s movements.
Tactical Methodologies (Sun Bin II)
- The Elite Vanguard: Essential for breaking enemy lines, capturing commanders, and seizing the initiative.
- The Power of Trust: Trustworthiness is the basis for soldiers’ willingness to die. Clear, fair rewards and punishments are necessary, but they are not the most crucial factor; the leader’s internal sincerity and care for troops are paramount.
- The Use of Deception:
- Misdirection: Using fake formations, false supply lines, or feigned incompetence to induce enemy complacency or to split their forces.
- The “Bird’s Bill”: Closing in on a scattered force from multiple sides.
- Terrain & Formation: Use terrain advantages (high ground, waterways) and formations (Awl, Goose, Round) to suit specific combat conditions.
- The “Way” of Warfare: The highest mastery is winning without combat. If combat is necessary, ensure preparations, timing, and terrain are aligned.
