Summary of The Art of War: The Oldest Military Treatise in the World

Overview:

The Art of War is a comprehensive treatise on military strategy and tactics written by Sun Tzu, a Chinese general and strategist, in ancient China. The text emphasizes the importance of planning, deception, and understanding the enemy. Sun Tzu outlines five key factors that govern warfare: the Moral Law, Heaven, Earth, the Commander, and Method and Discipline. He stresses the importance of speed, minimizing losses, and utilizing the terrain to one’s advantage. The text also addresses the use of spies and fire as a weapon.

Throughout the Art of War, Sun Tzu explores various scenarios and tactics using metaphors and historical examples to illustrate his points. He emphasizes that victory is achieved through careful planning, adaptability, and the ability to exploit the enemy’s weaknesses. Sun Tzu also stresses the importance of maintaining a strong morale within the army, while understanding and manipulating the enemy’s mindset.

Facts:

  • Sun Tzu, the author of the Art of War, was a native of the Ch’i State in ancient China. This is a definitive fact from the text. While there is debate about the extent of his actual military career, the text itself acknowledges his origin.
  • The Art of War was composed for King Ho Lu of the Wu State. This is explicitly stated in the text and confirmed by early commentators like Ts’ao Ts’ao.
  • The Art of War emphasizes the importance of deception in warfare. Sun Tzu says that “All warfare is based on deception” and provides various methods of employing deception to gain an advantage.
  • The Art of War advises against prolonged warfare. Sun Tzu argues that “There is no instance of a country having benefited from prolonged warfare.” He emphasizes the importance of speed and efficiency in military campaigns.
  • The Art of War stresses the crucial role of terrain in warfare. Sun Tzu outlines nine varieties of ground, each with its own set of tactical considerations.
  • The Art of War acknowledges the importance of maintaining a strong morale within an army. Sun Tzu advises treating soldiers with humanity but keeping them under strict control, emphasizing that a cohesive and motivated army is essential for success.
  • The Art of War highlights the crucial role of spies in warfare. Sun Tzu outlines five classes of spies and discusses various methods for utilizing them to gather information about the enemy.

Statistics:

  • An army of 100,000 men would cost 1,000 ounces of silver per day to maintain. This figure is given by Sun Tzu as an example of the substantial costs associated with warfare.
  • One cartload of the enemy’s provisions is equivalent to twenty of one’s own. This statistic illustrates Sun Tzu’s advice on foraging on the enemy’s supplies.
  • Three-tenths of the people’s income would be dissipated due to war. Sun Tzu details the economic burden of warfare on the people, highlighting the importance of swift operations to minimize these losses.
  • A successful siege can take up to six months to complete. This statistic highlights the importance of avoiding prolonged sieges, as they are costly in terms of resources and manpower.
  • A victorious army opposed to a routed one is as a pound’s weight placed in the scale against a single grain. This analogy emphasizes the significant advantage that a disciplined and victorious army possesses over a defeated force.
  • A general in difficult country should not encamp. Sun Tzu’s advice is based on the need to avoid vulnerable positions and ensure the safety of the army’s movements.
  • An army without its baggage-train, provisions, or bases of supply is lost. This statistic highlights the importance of maintaining a robust supply line for any successful military campaign.
  • A successful night march can cover double the usual distance. This statistic highlights the importance of speed and stealth in surprise attacks.
  • A day’s march is typically 30 li. This statistic provides context for the distances mentioned in Sun Tzu’s discussions on maneuvers and forced marches.
  • An army can be defeated if they have to prepare against possible attacks on multiple fronts. This statistic emphasizes the importance of keeping the enemy guessing about one’s plans and forcing them to spread their forces thin.
  • To successfully conquer a large state, it is necessary to prevent the concentration of its forces. This highlights the importance of dividing the enemy’s forces and limiting their ability to cooperate.
  • The ideal army is one where the courage and spirit of all ranks are equal. This highlights the importance of unity, discipline, and a strong morale within an army.
