Five Essential Rules of Successful Strategy

The key to success in any battle is to fight only when you are certain of winning, and to wait for the right opportunity. A great general avoids battles that he may lose, and always ensures that his army is prepared for any encounter. There are five essential rules for achieving victory: know when to fight and when not to, be ready to face superior or inferior forces, maintain discipline and fighting spirit in your ranks, strike so that you are prepared and your enemy is not, and command your troops without interference. A skilled strategist avoids fighting on the enemy’s terms and instead looks for opportunities to attack where the enemy is weak. It is important not to let anger cloud your judgment, and to avoid falling into your enemy’s traps. By securing yourself against defeat and waiting for the right moment, victory is achievable.

The Fatal Calamities of War

War is a brutal endeavor where victory or defeat can be determined by the actions of sovereigns and generals. A sovereign’s commands can impede an army, damaging their confidence and leading to defeat. Similarly, a general’s faults can also prove dangerous and result in the downfall of an army. Six potential calamities are identified, such as attacking a force ten times the size of one’s own, weak soldiers being worn down by officers, or a weak and indecisive general leading to a disorganized army. In warfare, success is only possible when the sovereign and generals avoid causing their own defeat.

Winning the War without Fighting

The book highlights the importance of quick and decisive victories in war and offers strategies to conserve resources through foraging and espionage. It advises against besieging walled cities and emphasizes the benefits of capturing the enemy’s army whole and intact. The author suggests that a skillful general will subdue enemies without fighting, and this tactic constitutes the ultimate triumph. The book stresses the value of engaging spies who can provide critical information for strategizing. The cost of maintaining spies is meager compared to the prolonged war they help avoid. The book suggests that single battles can end wars, and the use of stratagems around secrets provided by spies can turn the tide of the war. The book advocates for the conservation of resources through stratagems, foraging, and espionage instead of destroy-and-occupy tactics that exhaust the resources of any state and make it vulnerable.

The Art of Deception

The crux of ‘The Art of War’ is deception. To outwit the enemy, you must present weakness as strength and confusion as order, encouraging your adversary to become careless. The key is to keep your enemy guessing and control the initiative. Do not attack everything at once; rather, select poorly defended points, forcing your enemy to reveal their weaknesses. A clever combatant imposes their will on the enemy and attacks where they’re least prepared. To thwart your adversary in addition to deceiving them, force them to spread their forces thin by attacking on several fronts. Overall, to win the war, the key is to play with the enemy as a cat toy with a mouse.
