So, what exactly is _The Art of War_ all about, according to these passages? Well, right from the start, we're told that war is a really big deal – "A grave affair of state". It's literally "a place Of life and death, A road To survival and extinction," and it absolutely _must_ be thought about very, very carefully. It's not something to rush into without serious consideration. ### The Bedrock: Understanding the Fundamentals To even begin pondering this massive undertaking, Sun Tzu lays out Five Fundamentals that you need to deliberate upon, compare, and assess. Think of these as the essential building blocks for any successful plan. 1. **The Way:** This is all about unity. It's what makes everyone, from the highest ruler down to the common soldier, share the same goal and be willing to live or die together, without wavering. This deep alignment is absolutely crucial. _Have you ever seen a team truly united behind a purpose? What happens when that unity is missing?_ 2. **Heaven:** This refers to the natural elements and cycles – things like Yin and Yang, cold and hot, and the changing seasons. It's about understanding and working with the weather and celestial timing. 3. **Earth:** This covers the physical landscape. We're talking height and depth, distance and closeness, ease and danger, whether the ground is open or confined, and even its potential for life or death. Knowing your terrain is key to survival and maneuvering. 4. **Command:** This is about the qualities needed in a leader. A good commander needs wisdom, integrity, compassion, courage, and severity. It's a blend of intelligence, moral fiber, care for others, bravery, and the ability to be firm when necessary. _Which of these qualities do you think is most important in a leader, and why?_ 5. **Discipline:** This is the practical side of running an army. It involves organization, a clear chain of command, and careful control of spending. An undisciplined force is a chaotic one. Every commander needs to know these five things. Grasping them means victory, and failing to grasp them means loss. Beyond just knowing them, you have to ask the tough questions: Which ruler truly embodies the Way? Which general has the necessary ability? Which side is favored by Heaven and Earth? Whose discipline is more effective? Which army is stronger? Whose troops are better trained? And where are rewards and punishments clearest? By figuring these out, you can pretty much predict who will win and who will lose. ### The Art of Deception: Not What You See One of the most captivating ideas presented is that "The Way of War is A Way of Deception". This isn't about being sneaky just for the sake of it; it's a fundamental strategy. It means constantly presenting a false picture to your enemy. When you're able, make it look like you're not. When you're deploying troops, appear inactive. If you're close by, make yourself seem far away, and if you're far, make yourself seem near. The source gives us a whole list of ways to apply this deception: - Lure the enemy with bait. - Strike when they are in chaos. - If they are well-supplied ("full"), be prepared for them. - If they are strong, avoid them. - If they are angry, try to disconcert them. - If they are weak, provoke their pride. - If they are relaxed, constantly bother ("harry") them. - If their men are harmonious, find ways to split them up. - Always attack where the enemy is unprepared. - Always appear where you are least expected. This mastery of appearing where you aren't expected and attacking where the enemy isn't prepared is the key to victory in warfare. It's so vital that it can't be figured out or revealed beforehand. ### The Price of War: Why Speed Matters War is incredibly expensive and draining, not just on the battlefield but back home too. The source paints a vivid picture of the costs: maintaining a large army with chariots, wagons, and soldiers requires immense daily expenditure. Transporting provisions over long distances is a huge drain on public money and makes common people poor. When an army is nearby, prices shoot up, making life incredibly hard for ordinary folks who then feel the pressure of taxes and levies. Troops get worn out on campaigns, and families at home become destitute. The common people can lose a massive seven-tenths of their wealth, and a huge chunk of the public treasury goes just to replacing damaged equipment. Because war is such a burden, victory needs to be swift. If it drags on, men get tired, morale drops, sieges exhaust everyone, and long campaigns empty the treasury. When a nation is in this exhausted state, other potential enemies ("feudal lords") are likely to attack, and even the wisest leaders can't fix that. The source bluntly states that while haste in war can be foolish, it has _never_ seen delay that was wise. No nation has ever benefited from a protracted war. Without really understanding the harm war causes, you can't figure out the best way to conduct it for profit (meaning, minimal loss and maximum gain). This is why a skillful warrior doesn't keep drafting the same troops or constantly transport supplies from home. Instead, they bring initial equipment but then live off the enemy. Foraging enemy provisions is seen as twenty times more valuable than bringing your own, and the same goes for fodder. Getting men to fight intensely isn't just about wrath towards the enemy; it's also driven by the desire for rewards, like captured chariots and booty. Treating prisoners kindly and caring for them is also mentioned as a way to enhance your own strength after victory. The core message here is clear: prize victory, not long campaigns. A wise general holds the nation's fate in their hands, making decisions that lead to peace or peril. _This emphasis on speed and cost-effectiveness is perhaps surprising to some. How does this ancient view compare to modern warfare and its economic impact?_ ### Winning Without Fighting: The Ultimate Skill Sun Tzu makes a truly profound statement: the highest excellence isn't winning every battle, but defeating the enemy without _ever_ fighting. This leads to a hierarchy of attack methods, from highest to lowest: 1. Attack the enemy's strategy itself. This means undermining their plans before they can even put them into action. 2. Attack their alliances. Isolate them diplomatically and prevent others from joining their cause. 3. Attack their army. Engage their forces directly. 4. Attack cities. This is considered the lowest form of warfare. Siege warfare, attacking cities, is seen as a last resort. It's incredibly time-consuming and costly. It takes months just to get ready with siege weapons and ramps. A general who can't control their anger might impatiently send troops to attack like ants, resulting in massive, pointless casualties without even taking the city. Siege warfare is labeled a calamity. The truly skillful strategist is the one who defeats the enemy _without_ battle, captures cities _without_ sieging them, and overthrows states _without_ long wars. Their goal is to achieve total victory ("supremacy under heaven") with their forces and weapons still fresh and sharp, resulting in complete gain. This is called the method of strategic attack. When considering direct engagement, the source provides guidelines based on numerical superiority: - If your force is ten times larger than the enemy's, surround them. - If five times larger, attack them. - If twice as large, split your force into two to engage. - If forces are equally matched, fight it out. - If fewer in number, lie low. - If weaker, escape. - A small force foolishly fighting a larger one will be captured. ### The General's Role and Pitfalls The general is seen as the foundation, or "prop," of the nation. A solid general makes a strong nation; a flawed one makes it weak. However, the ruler can cause big problems for the army. Ordering troops to move or retreat at the wrong times is like "hobbling the army". Ignorant interference in military decisions confuses everyone. Meddling ignorantly in appointing officers also causes confusion. When the army is confused and perplexed, other powers ("feudal princes") will see an opportunity to cause trouble, leading to chaos and giving away victory. For victory, there are Five Essentials, some of which echo earlier points: 1. Know when it's right to fight and when it's not. 2. Understand how to effectively use both large and small numbers of troops. 3. Have officers and men who share a single will. Unity again! 4. Be prepared for the unexpected. 5. Have a capable general who isn't restricted by their ruler. These five essentials point the way to victory. ### Knowing Yourself, Knowing Your Enemy Here's one of the most famous lines: "Know the enemy, Know yourself, And victory Is never in doubt, Not in a hundred battles". It's that crucial. If you only know yourself but not the enemy, you'll win some battles but lose others. If you know neither yourself nor the enemy, you're guaranteed to lose every single battle. The skillful warrior's first priority is always ensuring their _own_ invulnerability. Then, they wait for the enemy to become vulnerable. Your own safety ("invulnerability") is something _you_ control, but the enemy's weakness ("vulnerability") is something you _cannot_ directly cause. Thus, you can know _how_ to be victorious, but you can't always _make_ victory happen just by wishing it. Being invulnerable is about defence. Being vulnerable opens you up to attack. Defence comes from a lack of opportunity for the enemy; attack exploits an abundance of opportunity. A skilled defender is hard to spot, like hiding deep underground. A skilled attacker strikes from unexpected places, like moving from high above. This allows them to protect themselves and achieve victory without needless loss. The text cautions against seeing ordinary victories as true skill. Winning easily, being acclaimed for skill, lifting autumn fur, seeing the sun and moon, or hearing thunder aren't true measures of exceptional ability in warfare. The truly skillful warrior of old won "Easy victories". Their victories weren't extraordinary; they were _flawless_ because they were _inevitable_. They defeated an enemy who was already set up for defeat. The skillful warrior stands on ground where they are invulnerable and never misses a chance when the enemy is vulnerable. The victorious army ensures victory first, then seeks battle. The defeated army rushes into battle hoping for victory later. A skillful strategist cultivates "The Way" (unity, morality) and preserves "the law" (discipline, rules). This is how they master victory and defeat. There's a step-by-step process for assessment leading to victory, which again starts with the ground: 1. Earth determines Measurement. (Understanding the physical terrain.) 2. Measurement determines Estimation. (Estimating the size and resources of forces based on the terrain.) 3. Estimation determines Calculation. (Calculating strengths, distances, provisions, etc.) 4. Calculation determines Comparison. (Comparing your forces and situation to the enemy's.) 5. Comparison determines Victory. (The side with the advantage based on comparison wins.) A victorious army is depicted as overwhelming, like a heavy weight against a grain or pent-up water crashing down a gorge. This all comes down to "Forms and Dispositions". _How might these steps apply beyond military strategy, say, in business or even personal planning?_ ### Energy and Deception: The Dynamics of War Managing a large army is fundamentally the same as managing a small one; it's about how you divide them. Fighting with many or few is also similar; it's about marshalling them effectively using signals like gongs and flags. Signals are literally the "Ears and eyes Of the army". They keep a large force focused so individuals don't act alone. The interplay of indirect and direct tactics is crucial. An army can defend itself effectively by using a combination of both. Understanding weakness and strength allows an army to strike with overwhelming force, like a millstone on an egg. In battle, you engage directly, but victory is secured indirectly. The warrior skilled in indirect warfare is endlessly adaptable, like Heaven and Earth, rivers and seas, or the cycles of nature. Just as five musical notes, five colours, or five flavours can combine in countless ways, the two dynamics of indirect and direct warfare can create inexhaustible variations. They constantly give rise to each other in a never-ending cycle. This leads to the concept of "Potential Energy." A rushing torrent carrying boulders has devastating momentum. A swooping falcon breaking its prey's back shows precise timing. The skillful warrior's energy is devastating, and their timing is taut. Their energy is like a drawn crossbow, and their timing is like releasing the trigger. Even in the seeming chaos of battle, there is underlying order and no chance of defeat if these principles are applied. Disorder is founded on order, fear on courage, weakness on strength. A key tactic is to make the enemy reveal their form. You provide a visible target or offer bait, and they are sure to respond. You cause them to move, then meet them with your full force. The skillful warrior exploits this potential energy; they don't put the burden on individual soldiers to create the force. They deploy their men well but rely on the overall momentum and positioning ("potential energy"). This is like rolling round boulders down a mountainside – the energy comes from the slope and the shape, not from pushing each individual stone. ### The Empty and the Full: Timing and Positioning Being first on the battlefield allows you to wait for the enemy while you are fresh. Arriving last means you rush into the fight already exhausted. The skillful warrior is active ("stirs") but remains undisturbed ("is not stirred"). They control whether the enemy comes to them or is prevented from coming. They exhaust a fresh enemy, starve a well-fed one, and unsettle a settled one. A crucial tactic is to appear where the enemy _must_ rush to defend, and to rush yourself to places where they least expect you. You can march long distances without tiring by going where the enemy isn't. You ensure victory by attacking places the enemy hasn't defended. You ensure your own defence by defending places the enemy isn't attacking. The skillful warrior attacks in a way that prevents the enemy from defending, and defends in a way that prevents the enemy from attacking. This mastery is incredibly subtle, described as being "Without form!" and "Without sound!". Such a warrior controls the enemy's fate. They advance irresistibly into the enemy's "emptiness" (where they are weak or absent). They retreat so swiftly and elusively that they cannot be caught. If you want to engage, you can make the enemy come to you by threatening something they are "obliged To rescue". If you _don't_ want to fight, you can simply hold your ground in a way that makes engagement impossible for the enemy, perhaps by distracting them elsewhere. The key is to be formless yourself while making the enemy's form visible. If you are concentrated in one place while the enemy is divided into many trying to guess your move, you can attack their few points with your many, making them weak. If you don't reveal your intended point of attack, the enemy has to reinforce everywhere, thus weakening every single point. Weakness comes from preparing everywhere; strength comes from forcing the enemy to prepare everywhere. Knowing the time and place of battle allows you to engage confidently even after a long march, but ignorance of these details leads to chaos and inability for different parts of your army to support each other. To master the empty and the full, you must scrutinize the enemy, know the flaws in their plans, and discover the reasons behind their actions. You must make their form visible to understand their strengths and weaknesses, their grounds of "death and life". The highest skill in arranging your forces is to be without form yourself. This formlessness protects you from even the cleverest spies or strategists. While others might see the victorious formations, they don't understand _how_ those forms were created. Victories are unique, adapting to the infinite circumstances of the enemy. Military dispositions are like water, avoiding the high and rushing to the low. War avoids the strong and attacks the weak. Water shapes its flow based on the land; the warrior shapes victory from the enemy's changing state. Just as nature is constantly changing (elements, seasons, moon), war has no constant strategy or form. Supreme skill is deriving victory from these ever-changing circumstances. ### Navigating the Battlefield: The Fray and Terrain Once the general has assembled the army and camped opposite the enemy, the real challenge, "The true difficulty," is "The fray itself". This difficulty involves making the difficult seem easy ("the crooked Straight") and turning bad situations into advantages ("making An advantage Of misfortune"). Taking a longer, roundabout path but luring the enemy and arriving first is an example of mastering the crooked and the straight. Engaging in the fray can bring gain or danger. Rushing your entire force for gain might still fail. Abandoning your camp for gain risks losing your equipment. Forced marches are incredibly taxing; marching 30 miles at double speed for gain could cost you all your commanders, with only one in ten soldiers arriving. Marching 15 miles might lose the vanguard commander and leave only half your men. Even marching 10 miles means losing a third of your force. An army is lost without its equipment, provisions, or base stores. Furthermore, you cannot form alliances without knowing the plans of other rulers. You cannot march effectively without knowing the terrain – hills, woods, cliffs, marshes. And you absolutely need local guides to exploit the land effectively. Ignorance of any of these points is a major failing for the army of a great leader. War, as mentioned before, is founded on deception. Movement is driven by advantage. The elements of change in war are division and unity. The source uses powerful imagery for how an army should be: rushing like wind, stately as a forest, ravaging like fire, still as a mountain, inscrutable as night, swift as thunder or lightning. When occupying new territory, plunder the countryside and divide the spoils, extend your control, and distribute the profits. Always weigh the situation carefully before acting. Mastering the strategy of the crooked and the straight leads to victory. The source also talks about managing the spirit and discipline of troops. Gongs and drums in night fighting, and banners and flags in daylight, transform the senses of the troops, focusing the army. An entire force or its general can lose their spirit or presence of mind. A soldier's spirit is strongest in the morning and weakens by evening. The skillful warrior avoids attacking when the enemy's spirit is keen and targets them when it's dull or homesick. This is mastery of spirit. Meeting chaos with discipline and tumult with calm is mastery of mind. Countering distance with closeness, exhaustion with ease, and hunger with plenty is mastery of strength. Not attacking well-formed or well-ordered enemy forces is mastery of change. The text provides several axioms, simple rules for engagement: - Do not advance uphill. - Do not attack an enemy with their back to a hill. - Do not pursue an enemy feigning flight. - Do not attack keen troops. - Do not take the bait when offered. - Do not thwart a returning army (they might be desperate). - Leave an escape route for a besieged army. - Do not press an enemy who is cornered ("at bay"). These are fundamental principles of the art of war. _Why do you think leaving an escape route or not pressing a cornered enemy is wise? What might happen if you don't follow these axioms?_ ### Adapting to Circumstances: The Nine Changes The general receives orders, assembles the army, and then must navigate various situations. The concept of the "Nine Changes" focuses on adapting plans based on the specific circumstances and terrain. For example: - On difficult-to-move-through terrain ("intractable ground"), don't encamp. - On ground where multiple routes meet ("crossroad terrain"), ally with others. - On terrain where survival is hard ("dire terrain"), don't linger. - On ground reached via narrow passes ("enclosed terrain"), make careful strategic plans. - On ground where the only option is desperate fighting ("death terrain"), fight. Furthermore, there are specific actions or situations to avoid: - Roads you shouldn't take. - Armies you shouldn't attack. - Towns you shouldn't besiege. - Terrains you shouldn't contest. - Ruler's orders you shouldn't obey. Yes, the source states a general should defy an order that is guaranteed to lead to defeat. A general who understands the gains of these Nine Changes truly understands warfare. One who knows the terrain but not the Nine Changes won't get the full benefit of that knowledge. A warrior ignorant of the Nine Changes, even if they know the "Five Gains," won't be able to maximize the effectiveness of their men. A wise leader always considers both gain and harm in their planning. By tempering their focus on immediate gain, they can achieve their larger goals. By tempering their fear or focus on potential harm, they can escape calamity. You can also influence others, like feudal lords, by causing them harm, keeping them busy, or enticing them with thoughts of gain. The skillful warrior relies on their own preparedness, not on the enemy _not_ coming. They rely on their own impregnability, not on the enemy _not_ attacking. The source also warns of the Five Pitfalls that can ruin a general: 1. **Recklessness:** Leads to destruction. 2. **Cowardice:** Leads to capture. 3. **A hot temper:** Prone to provocation. 4. **A delicacy of honour:** Tends towards shame. 5. **A concern for his men (excessive):** Can lead to trouble (presumably by making soft choices). These five are the "Bane of war," and if an army is defeated and its general killed, it's likely due to one of these flaws. They require very careful consideration. _Are these pitfalls still relevant for leaders today, outside of a military context?_ ### Mastering the Ground: Positions and Defeats Understanding terrain is vital for positioning your army against the enemy. Different types of terrain require different approaches: - **Mountains:** Cross mountains by staying near valleys. Camp high and face open ground. Fight downhill, not uphill. - **Rivers:** Cross rivers, then keep your distance. Don't attack the enemy midstream if they are crossing towards you; wait until they are halfway or more across. If you _do_ want to fight near a river, don't be right next to it. Occupy high ground facing the open. Don't move against the river's current. - **Salt Marshes:** Cross them quickly; don't linger. If you must fight in a marsh, stay near water plants with trees behind you. - **Level Ground:** Occupy easy terrain. Keep high ground to your right and rear, facing danger ("death") while keeping safety ("life") behind you. Mastering these positions based on the terrain is ancient wisdom, credited to the Yellow Emperor using them to defeat others. Armies prefer high ground and sunny sides ("Yang"), avoiding low and shady areas ("Yin"). Occupy solid ground to keep your troops healthy and ensure victory. On mounds, hills, banks, or dikes, take the high, sunny side with high ground to your right and rear, using the land's features to your advantage. If rivers are swollen, wait for the water to go down before crossing. Avoid naturally dangerous places like deep gorges, wells, prisons (likely natural traps), nets, traps, or cracks in the ground ("Heaven's Torrents, Heaven's Wells," etc.). Keep away from them yourself and ideally let the enemy get near them. Be extremely cautious in ravines, swamps, marshes, forests, or thick undergrowth – these are prime spots for ambush and spies. The source also lists six ways a general's fault, not natural disaster, leads to defeat: 1. **Flight:** Occurs when equally matched forces face an enemy ten times larger. (This sounds like a mismatch, but the text blames the general, perhaps for not assessing the situation or positioning correctly?) 2. **Impotence:** When troops are strong but officers are weak. 3. **Decay:** When officers are strong but troops are weak. 4. **Collapse:** When superior officers are angry and insubordinate, charging into battle without the general's approval or judgment. 5. **Chaos:** When the general is weak, lacks severity, gives unclear orders, lacks fixed rules, and troops are sloppy. 6. **Rout:** When the general misjudges the enemy, sends a weaker force against a stronger one, or fails to pick a good vanguard. These six are the "Way of Defeat" and must be studied carefully. The form of the terrain is an army's ally, and assessing the enemy and the difficulty, danger, and distance of the terrain are part of the "Way Of the Superior General". Knowing and practicing these ensures victory; not knowing ensures defeat. The general who advances or retreats based on the likelihood of victory, even against the ruler's direct order, and whose sole aim is to protect the people and serve the lord, is called "A Jewel of the Realm". Such a general treats their troops like children or loved ones, inspiring immense loyalty. However, a general who is too generous or affectionate but lacks command and order will have useless, spoiled troops. You only have "Half of victory" if you know your troops can attack but don't know if the enemy is vulnerable. The same goes if you know the enemy is vulnerable but your troops can't attack, or if you know both but the terrain isn't suitable. The wise warrior isn't confused when they move or at a loss when they act. This brings us back to the core principle: knowing the enemy, knowing yourself gives victory in any battle. Add to that knowing Heaven and Earth, and your victory is complete. ### The Nine Kinds of Ground: Actions for Every Situation The source further categorizes terrain into Nine Kinds of Ground, each requiring a specific approach: 1. **Scattering ground:** Home territory where troops are easily dispersed. Action: Do not fight. Unit the will of your men. 2. **Light ground:** Entering enemy territory but not deeply. Action: Do not halt. Keep them connected. 3. **Strategic ground:** Offers advantage to either side. Action: Do not attack (defensively?). Bring up your rear (secure your position). 4. **Open ground:** Both sides can move freely. Action: Do not block (don't get caught static). See to your defences. 5. **Crossroad ground:** Borders multiple states, taking it gives mastery of the empire. Action: Form alliances. Strengthen your alliances. 6. **Heavy ground:** Deep in enemy territory with fortified towns in the rear. Action: Plunder (to feed your men). Ensure continuity of supplies. 7. **Intractable ground:** Difficult terrain like mountains, forests, marshes. Action: Keep marching (don't get bogged down). Keep on the move. 8. **Enclosed ground:** Reached via narrow gorges, hard to retreat from. Action: Devise stratagems. Block the passes (to control access). 9. **Death ground:** Survival requires desperate struggle; without it, you perish. Action: Fight. Demonstrate the desperateness of the situation (to inspire courage). The skillful warrior of old used these principles to prevent the enemy from coordinating their forces. They made their move only when there was gain and halted when there was none. When facing a numerous and well-organized enemy, the advice is to seize something they cherish, and they will do your will. Speed is the essence of war. Exploit the enemy's lack of preparedness, attack unexpectedly, and take unusual routes. Deep penetration into enemy territory brings cohesion to your own troops, making the enemy less likely to prevail. Plundering fertile land feeds your men. Cherish and nurture your troops, concentrate their energy, and use unpredictable maneuvers. Putting men where there is no escape, "Death ground," forces them to fight rather than flee. Troops facing death will give their all; they know no fear, stand firm, persist, and fight when hope is lost. They become alert, act, are devoted, and loyal even without strict discipline or orders. Forbidding omens and casting out doubts makes them willing to fight to the death. Troops on the way to battle might weep, but when thrown into a desperate situation, they fight with incredible courage. The army should be like the shuairan snake, which strikes with head and tail no matter where it's hit. Or like enemies from Wu and Yue who help each other in a storm when sharing a boat. It's not enough just to secure positions; there must be a single, unified courage throughout the army. This is the key to managing an army, enabling both strong and weak soldiers to serve effectively based on the terrain and situation. The skillful warrior directs their army as if it were one person, giving them no choice but to obey. The general's role is to be calm ("still") and mysterious ("inscrutable"), upright and fair ("impartial"). They must keep their _own_ troops unaware of full plans ("in ignorance") to deceive the enemy. Constantly changing plans and shifting camp keeps the enemy in the dark. Leading men into battle is like climbing a height and kicking away the ladder – removing the option of retreat. It's about plunging them deep into enemy territory and "releasing the trigger". Burning boats or breaking pots are examples of showing there's no turning back. It's like a shepherd driving sheep – no one knows the final destination. Assembling troops and throwing them into danger is part of the commander's business. To master these concepts, you must study the variations of the Nine Kinds of Ground, the advantages of flexible maneuvers, and the principles of human nature. Shallow penetration brings scattering, while deep penetration brings cohesion. When surrounded, a soldier resists; when all seems lost, they struggle; when in danger, they obey. This innate nature is exploited on death ground. A great king's army doesn't allow the enemy to concentrate, overawes them, undermines their alliances, pursues secret plans, captures cities, and destroys states. Such a leader can distribute rewards and publish orders flexibly, not bound by strict rules or precedents. They treat the army as one unit, focusing them on the task without over-explaining, showing the advantage but not necessarily the danger upfront. Putting them in peril makes them survive; plunging them into death ground makes them live. Danger can lead to victory. Success comes from scrutinizing enemy intentions and using them. You can even kill the enemy general from hundreds of miles away by focusing on them. This is success through cunning. On the day of attack, secure your position (close passes), cut off communication (destroy tallies, break off with envoys), and be firm in your decision. If the enemy exposes a weakness, rush in. Seize something valuable to them and secretly set up a decisive encounter. Discard rigid rules and adapt to the enemy. Start cautiously, like a maiden, but when the enemy opens the door, attack with lightning speed, like a hare. They won't be able to withstand you. _How does this blend of seeming passivity and sudden ferocity work? What does it exploit in the enemy?_ ### Special Tactics: Fire and Spies The source mentions Attack by Fire as a specific tactic, listing five ways to use it: 1. Burn men. 2. Burn supplies. 3. Burn equipment. 4. Burn warehouses. 5. Burn lines of communication. Attacking by fire requires having the necessary materials ready. There's a right season (hot, dry weather) and specific days (linked to constellations associated with rising wind) for starting fires. When attacking with fire, you must adapt: if fire breaks out inside the enemy camp, respond from outside. If the enemy stays calm despite the fire, wait; let the fire get strong before following up, and only if possible. If you can start a fire from outside, don't wait for one inside; start it when the time is right. Always be upwind, never attack from downwind, as day winds last longer than night winds. Knowing these "Five Changes of Fire" is important, and vigilance is key. Fire is a mighty assistant to attack. Water can also help, but it can only isolate, not take away the enemy's power. ### The Power of Knowledge: Espionage Finally, one of the most emphasized points is the importance and cost-effectiveness of Espionage. Raising a massive army and marching them hundreds of miles is incredibly expensive, drains the nation, exhausts troops, disrupts civilian life, and keeps countless families from their work. Two armies can confront each other for years, waiting for one decisive battle. Given these massive costs, it's considered incredibly short-sighted ("callous") and incompetent ("No commander of men") to refuse to spend a relatively small amount of money (a hundred taels of silver) to get crucial information about the enemy. Prior information, gained through intelligence, is what allows wise rulers and worthy generals to move effectively, conquer, and achieve success far beyond others. This information doesn't come from spirits, analogy, or calculations; it comes _only_ from people who know the enemy's situation. There are Five Sorts of Spies: 1. **Local:** Come from the enemy's fellow countrymen. 2. **Internal:** Come from the enemy's officials. 3. **Double:** Are the enemy's own spies whom you've turned. 4. **Dead:** Spies given false information to feed to the enemy, leading to their eventual capture or death. 5. **Live:** Spies who return with information. When all five types are working together, it's a secret and powerful system ("The Mysterious Skein, The Lord’s Treasure") that no one can figure out. Spies should be the closest and most trusted individuals to the commander, highly rewarded and treated with confidence. To use spies effectively requires wisdom, humanity, justice, subtlety, and ingenuity to verify their reports. Spies have countless uses. Prematurely revealing secret intelligence is a capital offense for both the spy and the recipient. To attack an army, city, or even an individual, you need detailed information beforehand, like the names and roles of the enemy general and their key staff. Your spies must find this out. Enemy spies trying to get information on you must be found, bribed, won over, and treated well so they can be used as "Double agents". The double agent is the key; they help you discover local and internal spies, learn how to feed misinformation to the enemy, and know when and how to use live spies. Because of their critical role, double agents must be treated generously. Historically, the rise of powerful dynasties was linked to using individuals who had served the previous rulers as intelligence assets. Only enlightened rulers and worthy generals understand how to use high-level intelligence for spying and thus achieve great success. Spies are called a "key element" in warfare, as an army's every move depends on them. _Considering the emphasis on double agents, what ethical questions does this raise? How might this ancient approach to intelligence compare to modern espionage?_ ### In Conclusion and Further Exploration This briefing touches on many core ideas presented in the sources: the careful consideration required for war, the fundamental factors determining success, the pervasive use of deception, the harsh realities of cost and time, the strategic prioritization of attacking plans and alliances over armies and cities, the importance of knowing yourself and your enemy, the dynamic use of forces and timing, the critical role of terrain and adaptation, the leadership qualities needed (and avoided) in a general, and the absolute necessity of intelligence gathering. Sun Tzu's teachings, as seen here, aren't just about fighting; they're about avoiding fighting when possible, understanding the dynamics of power, being adaptable, and gathering crucial information. It's a holistic view that encompasses planning, logistics, leadership, psychology, and intelligence. To explore further, you might ponder: - How can the Five Fundamentals (The Way, Heaven, Earth, Command, Discipline) be applied to non-military situations like business or project management? - What are modern examples of "attacking the enemy's strategy" or "attacking their alliances" in international relations or competition? - The source talks about achieving "flawless" victories by defeating an _already defeated_ enemy.
