Name: The Art of War
Author: Sun Tzu

General Overview
- Central Thesis
  - War is a vital art: a road to safety or ruin, never neglected, always calculated.
  - Victory without battle: supreme excellence breaks enemy resistance without fighting.
  - Know enemy and self: foreknowledge through comparison and spies guarantees success.
  - Adaptation: be formless as water, adjusting to enemy and terrain in infinite variation.
  - General's burden: discipline, humanity, and command freedom make him the state's bulwark.
- Laying Foundations (I–IV)
  - Five factors: Moral Law, Heaven, Earth, Commander, and Method govern strategic deliberation.
  - Deception as essence: feign ability and distance; entice, irritate, and strike unprepared.
  - Speed over protraction: no state benefits from prolonged war; forage on the enemy.
  - Supreme excellence: capture states and armies intact; sieges are the worst strategy.
  - Invincibility first: make yourself undefeatable, then await the enemy's vulnerability.
  - Five calculations: measurement, estimation, calculation, balancing, and victory forecast the outcome.
- Energy and Maneuver (V–VI)
  - Chêng and ch’i: direct force fixes; indirect force wins; combinations are inexhaustible.
  - Momentum and timing: onset like a torrent, decision like a falcon striking the instant.
  - Seize the initiative: arrive first, impose your will, march where undefended.
  - Concentrate, divide: keep forces united; make the enemy prepare everywhere and be weak everywhere.
  - Be like water: avoid strength, strike weakness; no constant shape or repeated tactics.
- Tactical Variation and Terrain (VII–X)
  - Maneuvering difficulty: winding routes, forced marches, and supply lines decide arrival and survival.
  - Command unity: gongs, drums, banners focus a host; brave or coward cannot act alone.
  - Advantages of variation: refuse some roads, armies, towns, commands; blend gain and danger.
  - Terrain reading: camp by mountains, rivers, marshes, plains; read birds, dust, and troop behavior.
  - Six calamities: flight, insubordination, collapse, ruin, disorganization, rout stem from poor command.
  - Know the ground: victory is complete when enemy, self, Heaven, and Earth are known.
- The Nine Situations (XI)
  - Nine grounds: from dispersive home soil to desperate ground; each demands its own response.
  - Desperate ground: no escape makes soldiers fight hardest; deadly peril produces safety.
  - Rapidity as essence: exploit unreadiness, unexpected routes, and unguarded spots.
  - Unity as organism: move the army like a single man; even enemies cooperate in a storm.
  - Deception and secrecy: mystify troops, kick away the ladder, commit beyond recall.
  - Maiden's guile, hare's burst: appear timid, wait for the opening, then strike with explosive speed.
- Fire and Spies (XII–XIII)
  - Five fire attacks: burn camps, stores, trains, arsenals; act only with advantage and restraint.
  - No pique: anger changes, but a destroyed kingdom never returns; leaders cultivate resources.
  - Foreknowledge only from men: spies, not spirits or analogies, reveal the enemy.
  - Five spy classes: local, inward, converted, doomed, surviving; converted spies are the pivot.
  - Generous management: spies share confidence, liberal rewards, and the leader's subtlety.
Deep Dive
- Introduction
  - Introduction · I
    - The Biographical Record
      - Ssu-ma Ch'ien's account: Sun Tzu, a native of Ch'i, served King Ho Lu of Wu.
      - The concubine test: 180 women drilled; he beheaded the king's favorites to enforce discipline.
      - Command doctrine: unclear orders blame the general; clear orders disobeyed blame the officers.
      - Proven in war: Sun Tzu defeated Ch'u, entered Ying, and awed Ch'i and Chin.
    - The Case for Skepticism
      - Tso Chuan silence: the greatest contemporary record never mentions Sun Wu as general or author.
      - Yeh Shui-hsin's attack: lesser figures are recorded, so omitting so brilliant a general is incredible.
      - Anachronism argument: professional generals did not exist before the Warring States period.
      - Forgery hypothesis: the book may be a later private scholar's work, not applied by Wu.
      - Concubine story dismissed: the experiment on palace women is "utterly preposterous and incredible."
    - Evidence for the Work's Antiquity
      - Widespread quotation: Wu Ch'i and Huai-nan Tzu plagiarize it, placing it before the 5th century B.C.
      - Archaic vocabulary: obsolete word meanings confirm an early textual date.
      - Internal markers: references to old land-tenure, armored chariots, and Wu as a living state.
      - Skeptic's concession: even Yeh dates the style to the early fifth century.
    - Textual History
      - Ts'ao Ts'ao's preface: Sun Tzu's work is the profoundest on war; his age missed its essential purport.
      - The 82 chapters: Han Shu lists an expanded corpus, but Ssu-ma Ch'ien knew only the 13.
      - Accretion theory: apocryphal writings collected under Sun Tzu's name; later bibliographies prove it.
      - Authentic core: the 13 chapters existed in Ssu-ma Ch'ien's time essentially as we have them now.
  - Introduction · II
    - Authorship and Historical Dating
      - Yeh Shui-hsin's theory: untenable; text reflects a practical soldier's observation and experience.
      - Two internal references: to Wu-Yueh enmity, not Ch'u, pointing to late dates.
      - Ch'u absent: Sun Tzu's 13 chapters never mention Ch'u, Wu's great enemy before 506 B.C.
      - Composition window: likely 505-496 B.C. if written for Ho Lu; could be later if not.
      - Author's status: not eminent; Tso Chuan's silence outweighs Shih Chi's account.
    - Historical Legend and Reconstruction
      - Legend's origin: book's celebrity may have created mythical biography for its author.
      - Capture of Ying: greatest feat of Ho Lu's reign, later credited to Sun Wu by popular identification.
      - Conjectured life: entered Wu service about Ho Lu's accession, subordinate officer, present at Ying.
      - Yueh's attack: convinced him the upstart kingdom was the future great enemy.
      - Irony: China's most illustrious man of peace contemporary with its greatest war writer.
    - Textual Transmission
      - Early text: Ssu-ma Ch'ien's 13 chapters essentially same as extant.
      - Ts'ao Kung: first commentator, no ground to suppose he tampered with text.
      - Standard edition: Chi T'ien-pao's Sung collection became sole field; lost then rediscovered.
      - Sun Hsing-yen's recension: compared older T'ung Tien and T'ai P'ing Yü Lan versions to restore text.
      - Result: "standard text" is closest approximation to Sun Tzu's original work.
    - The Eleven Commentators
      - Ts'ao Ts'ao (Ts'ao Kung): austere, compressed notes; characteristic of the stern commander.
      - Meng Shih and Chia Lin: meager and scanty; dates uncertain, least valuable.
      - Li Ch'uan and Tu Yu: Li's notes short and pointed; Tu Yu's from T'ung Tien, repeats predecessors.
      - Tu Mu: copious notes with historical parallels; summary of gist: benevolence plus artifice.
      - Ch'en Hao and Mei Yao-ch'en: Ch'en attacks Tu Mu; Mei's commentary praised by Ou-yang Hsiu.
  - Introduction · III
    - The Commentators
      - Sun Wu's style: terse diction, deep meaning, strict logical sequence, obscured by later critics.
      - Mei Yao-ch'en: best commentator; brushed aside old prejudices and restored the true meaning.
      - Wang Hsi: original but untrustworthy; his readings compare poorly with Ts'ao Kung's.
      - Ho Yen-hsi: supplies helpful additions and copious extracts from dynastic histories.
      - Chang Yu: lucid master of exposition, expanding Ts'ao Kung's cryptic sentences.
      - Sung florescence: military commentary boomed after frontier defeats in 1038–42.
    - Appreciations
      - Great generals: Han Hsin, Feng I, Lu Meng and Yo Fei all studied Sun Tzu with enthusiasm.
      - Literary praise: Su Hsun and Cheng Hou ranked Sun Tzu above the revered classics.
      - Cheng Hou's verdict: terse yet elegant, simple yet profound, perspicuous and practical.
      - Chu Hsi's caveat: this high praise risks encouraging unrelenting warfare and militarism.
    - Apologies for War
      - China's paradox: endless clash of arms, yet mainstream sentiment from Lao Tzu downward was pacifist.
      - Ssu-ma Ch'ien: weapons are the Sage's means to punish cruelty, calm turmoil, and rescue the imperiled.
      - Tu Mu: war is punishment, a function of government, no different in kind from flogging.
      - Civil-military split: scholars' shame about war made them lose sight of fundamental principles.
      - Confucius armed: though saying "I never studied armies," he used force at Chia-ku and conquered.
    - Answering Objections
      - Study completed by practice: Chao Kua's defeat condemns half-learning, not military theory.
      - Guile is lawful: war's treacherous nature demands stratagem; even Confucius broke an extorted oath.
      - Sun Hsing-yen: Confucius's "I am unversed" means only that he did not specialize in war.
      - Leaders must learn war: one who commands armies needs Sun Tzu's art; victory belongs to practiced generals.
- Chapters I–IV
  - Chapters I–IV · I
    - I. Laying Plans
      - War's gravity: vital to the state; a road to safety or ruin; never to be neglected.
      - Five factors: Moral Law, Heaven, Earth, Commander, and Method and discipline govern all strategic deliberation.
      - Moral Law and Commander: people united with the ruler; commander embodies wisdom, sincerity, benevolence, courage, strictness.
      - Seven comparisons: moral law, ability, terrain, discipline, strength, training, and consistent rewards forecast victory or defeat.
      - Deception as essence: feign inability or distance; entice, irritate, divide; strike where unprepared.
      - Calculations: many temple deliberations beforehand lead to victory; few or none lead to defeat.
    - II. Waging War
      - Cost of war: an army of 100,000 costs a thousand ounces of silver daily; protraction exhausts the state.
      - Perils of delay: weapons dull, ardor dampens, strength drains, and rivals seize the advantage.
      - Speed over cleverness: no country has benefited from prolonged war; victory demands rapid conclusion.
      - Forage on the enemy: one cartload of enemy provisions equals twenty of one's own in saved transport.
      - Rewards and integration: reward first captors, replace enemy flags, treat prisoners kindly, and use the conquered to augment strength.
      - General's burden: the leader of armies is arbiter of the people's fate, peace, or peril.
  - Chapters I–IV · II
    - The Supreme Victory
      - Take whole, not shattered: capture the enemy's state and forces intact; destruction is inferior.
      - Supreme excellence: break the enemy's resistance without fighting; conquest by stratagem, not bloodshed.
      - Victory without loss: dispute mastery of the Empire with forces intact; triumph complete.
    - Hierarchy of Strategies
      - Best: balk the enemy's plans with active counter-attack, not passive defense.
      - Next: prevent the junction of enemy forces, isolating them from allies.
      - Lesser: attack the enemy's army in the field.
      - Worst: besiege walled cities; costly and slow.
    - The Folly of Sieges
      - Avoid sieges: mantlets, movable shelters, and mounds take months to prepare.
      - Impatient assault: enraged general sends men like ants; one-third slain, town untaken.
      - Skillful capture: subdue troops without fighting, capture cities without siege, overthrow kingdoms without lengthy operations.
    - Force Ratios and Engagement
      - Ten to one: surround the enemy.
      - Five to one: attack directly.
      - Two to one: divide forces to strike front and rear.
      - Equal or slightly inferior: offer battle if able; otherwise avoid, or flee if utterly unequal.
      - Small force in stubborn fight: will be captured by the larger force in the end.
    - The General and the State
      - General is bulwark: if complete, State strong; if defective, State weak.
      - Ruler's first error: commanding advance or retreat while ignorant the army cannot obey — hobbling it.
      - Ruler's second error: governing an army as a kingdom — causes restlessness.
      - Ruler's third error: employing officers without discrimination — shakes soldiers' confidence.
      - Anarchy flings victory away: restless and distrustful army invites trouble from other princes.
    - Five Essentials and Knowing Self and Enemy
      - Know when to fight: wins who attacks or defends at the right time.
      - Handle superior and inferior forces: adapt through locality and timing.
      - Unity of spirit: army animated by the same spirit throughout all ranks wins.
      - Preparedness: prepared self waits to take the enemy unprepared.
      - No sovereign interference: general with military capacity and free command wins.
      - Know enemy and self: know both, fear no hundred battles; know one, win and lose; know neither, succumb every battle.
  - Chapters I–IV · III
    - The Primacy of Invincibility
      - Invincibility first: good fighters make themselves undefeatable, then await the enemy's moment of vulnerability.
      - Defeat is self-made: securing against defeat lies in your own hands; the enemy supplies the opportunity for victory.
      - Knowing vs doing: you may know how to conquer without being able to do it.
      - No mistakes: victories come from making no blunders, conquering an enemy already defeated.
    - Defense and Offense
      - Defensive tactics: security against defeat; chosen when strength is insufficient.
      - Offensive tactics: ability to defeat the enemy; chosen when strength is superabundant.
      - Skilled defense: hides in the earth's secret recesses so the enemy cannot locate him.
      - Skilled attack: flashes from the heights like a thunderbolt, giving the enemy no time to prepare.
    - The Invisible Victory
      - True excellence: winning before the common herd sees victory, without public acclaim.
      - Winning with ease: the clever fighter excels in easy conquest, not in hard-fought battles.
      - No reputation: victories over unseen circumstances earn neither wisdom's fame nor courage's credit.
      - Bloodless triumph: the enemy submits before bloodshed, so the world never knows the deed.
    - Victory Before Battle
      - Battle after victory: the victorious strategist seeks battle only after victory has been won.
      - Defeat's path: the destined loser fights first, then looks for victory.
      - Moral law and method: the consummate leader cultivates moral law, method, and discipline to control success.
      - Position as preparation: all arrangements and precautions make defeat impossible and enable the right moment.
    - The Five Calculations
      - Five terms: Measurement, Estimation of quantity, Calculation, Balancing of chances, Victory.
      - Chain of dependence: Earth gives Measurement; Measurement gives Estimation; Estimation gives Calculation; Calculation gives Balancing; Balancing gives Victory.
      - Comparative weight: a victorious army outweighs a routed one like a pound against a grain.
      - Irresistible force: a conquering army's onrush is like pent-up waters bursting into a thousand-fathom chasm.
- Chapters V–VI
  - Chapters V–VI · I
    - Organization and Control
      - Dividing numbers: large forces are controlled like small ones by breaking into subordinate units.
      - Signs and signals: coordinating a host in battle is a matter of agreed communications.
      - Direct and indirect maneuvers keep the whole array unshaken against attack.
    - Direct and Indirect Maneuver
      - Chêng and ch’i: direct force fixes the enemy; indirect force wins victory.
      - Endless combinations: five notes, colors, and tastes yield infinite variations; two maneuvers likewise.
      - Mutual interchange: direct and indirect lead into each other like a circle, inexhaustible.
      - Surprise flips to direct: once the enemy perceives an indirect move, it becomes direct.
    - Energy and Timing
      - Onset like a torrent: momentum rolls stones along, crushing what stands before it.
      - Decision like a falcon: strike at the measured instant, with self-restraint and timing.
      - Crossbow and trigger: energy is stored in formation; decision releases it suddenly.
      - Terrible onset, prompt decision are the marks of the good fighter.
    - Concealment and Deception
      - Simulated disorder requires perfect discipline underneath.
      - Feigned fear requires real courage; feigned weakness requires real strength.
      - Deceptive appearances keep the enemy moving; sacrifice baits to lure him.
      - Lying in wait: tempting baits plus picked troops ambush the pursuing enemy.
    - Combined Momentum
      - Use combined energy, not excessive demands on individual soldiers.
      - Logs and stones: on level ground they rest; on a slope they roll; round shapes descend.
      - Momentum of round stone rolled from a mountain height gives victory with small forces.
  - Chapters V–VI · II
    - Seize the Initiative
      - First in the field: arrive fresh and await the enemy; force him to hasten and arrive exhausted.
      - Impose your will: fight on your own terms or not at all; lure or damage to control the enemy's movements.
      - Harass and provoke: disturb an enemy at ease, starve the well-supplied, and force the encamped to move.
      - March where undefended: move through unguarded country and appear at points where you are not expected.
    - Attack Weakness, Defense Impenetrable
      - Attack undefended places: success is certain when the enemy cannot defend; hold positions that cannot be attacked.
      - Subtlety and secrecy: by becoming invisible and inaudible, you hold the enemy's fate in your hands.
      - Irresistible advance and safe retreat: strike weak points; retire more rapidly than the enemy can pursue.
      - Force or avoid battle: attack a place the enemy must relieve to bring him to fight; baffle him to prevent engagement.
    - Concentrate While Dividing the Enemy
      - Keep forces united: visible enemy dispositions plus our own invisibility let us concentrate while the enemy disperses.
      - Whole against fractions: pit many against few by compelling the enemy to prepare at several points.
      - Reinforcement creates weakness: strengthening the van weakens the rear; spreading forces everywhere makes them weak everywhere.
      - Numerical strength is relative: weakness comes from preparing against attacks; strength comes from forcing the enemy to prepare against ours.
      - Fix time and place: concentration from afar wins; uncertainty leaves wings, van, and rear unable to support each other.
    - Discover the Enemy
      - Victory despite numbers: if the enemy ignores time and place, superior numbers will not save him.
      - Rouse and test: provoke the enemy to reveal activity or inactivity; force him to expose his vulnerable spots.
      - Compare strengths: know where the opposing army is superabundant and where it is deficient.
      - Victory is invisible: all see the tactics of conquest, but none see the strategy from which victory evolves.
    - Be Like Water
      - Avoid strength, strike weakness: as water flows downhill, war avoids the strong and attacks the weak.
      - No constant shape: adapt tactics to the foe as water adapts its course to the ground.
      - Never repeat tactics: let methods be regulated by infinite variety; the heaven-born captain modifies plans per opponent.
      - Nature's changes: elements, seasons, days, and moon illustrate that warfare has no constant conditions.
- Chapters VII–VIII
  - Chapters VII–VIII · I
    - The Difficulty of Maneuvering
      - Deviation: turn the devious into direct by enticing the enemy away, then reach the goal first.
      - Forced marches: 100 li loses all leaders, 50 li half the force, 30 li two-thirds arrive.
      - Supplies: an army without baggage-train, provisions, or bases of supply is lost.
      - Terrain and allies: know neighbors’ designs, the country’s features, and use local guides before marching.
    - Speed and Disposition
      - Momentum: be swift as wind, compact as forest, ravaging as fire, immovable as mountain.
      - Plans and strikes: keep plans dark as night, then fall like a thunderbolt.
      - Adaptability: concentrate or divide troops according to circumstances; dissimulate to succeed.
      - Spoils: divide plunder fairly and allot conquered territory to soldiers for self-sustaining campaigns.
    - Command and Control
      - Signals: gongs, drums, banners, and flags focus the ears and eyes of the host on one point.
      - Unity: a single body makes it impossible for the brave to advance alone or the cowardly to retreat alone.
      - Day and night: use fire and drums by night, flags and banners by day.
    - Psychology and Timing
      - Spirit and moods: attack when the enemy’s morning keenness has flagged and minds turn homeward.
      - Self-possession: await disorder calmly, stay near while the enemy toils, remain well-fed against famished foes.
      - Circumstances: refuse to intercept orderly banners or attack calm, confident arrays.
    - Rules of Engagement
      - Ground rules: never advance uphill or oppose a downhill enemy.
      - Ruses: do not pursue feigned flight, swallow bait, or block an army returning home.
      - Desperate foe: leave an outlet when surrounding; never press a cornered enemy too hard.
  - Chapters VII–VIII · II
    - The Need for Tactical Variation
      - Tactical variation: the general’s highest art, outranking mere knowledge of terrain or fixed advantages.
      - Ground dictates conduct: no camping in difficult country, ally where roads intersect, do not linger in isolated positions.
      - Extreme situations: use stratagem when hemmed in; fight when desperate.
      - Know what to refuse: some roads, armies, towns, positions, and even sovereign commands must be disobeyed.
      - Variation unlocks knowledge: without it, even topographical grasp and the Five Advantages fail in practice.
    - Blending Advantage and Disadvantage
      - Temper expectation of gain by weighing the enemy’s power to harm you.
      - Balanced counsel lets the essential part of your plan succeed.
      - In difficulty, seek advantage actively; it is the way to extricate yourself from misfortune.
      - Weaken hostile chiefs: damage their assets, keep them engaged, and lure them toward chosen points.
    - Readiness Over Assumption
      - Rely on readiness, not on the enemy’s absence: prepare to receive him and make your position unassailable.
    - Five Dangerous Faults of a General
      - Recklessness invites destruction.
      - Cowardice leads to capture.
      - Hasty temper can be provoked by insults.
      - Sensitivity to shame makes a leader vulnerable to slander.
      - Over-solicitude for men sacrifices military advantage to comfort and brings ruin.
- Chapters IX–X
  - Chapters IX–X · I
    - Camping by Terrain
      - Mountains: pass quickly, camp near valleys in high sunny spots; never fight uphill.
      - Rivers: after crossing, move far from the river; strike when half the enemy has crossed.
      - Marshes: cross them without delay; if forced to fight, keep water, grass, and trees to your rear.
      - Plains: choose accessible ground, high to the right and rear, so danger lies ahead.
      - Dangerous ground: abandon defiles, thickets, quagmires, and crevasses; lure the enemy into them instead.
    - Reading Natural Signs
      - Quiet enemy: close and still means reliance on a strong position.
      - Provocative enemy: keeping aloof and challenging means he wants you to advance.
      - Easy camp: an accessible encampment is a deliberate bait.
      - Wildlife: birds rising signal ambush; startled beasts signal imminent attack.
      - Dust columns: high dust means chariots, low wide dust means infantry, drifting dust means foraging or camping.
    - Reading Troop Behavior
      - Speech: humble words with preparations mean attack; violent words with advance mean retreat.
      - Water and food: thirsty soldiers drink before filling vessels; hungry soldiers lean on spears.
      - Camp signs: night clamor shows fear, shifting banners show sedition, angry officers show worn-out men.
      - Desperate resolve: feeding grain to horses, killing cattle, and abandoning cooking pots mean fight to the death.
      - Exhaustion: seeing an advantage and not taking it proves the soldiers are spent.
      - Envoys: compliments mean truce; peace terms without sworn oaths mean a plot.
    - Command and Discipline
      - Numbers: equal numbers suffice for defense; avoid frontal attack—concentrate, watch, and reinforce.
      - Contempt: the general who scorns his opponents invites capture.
      - Loyalty before punishment: punish before attachment creates useless troops; attachment without enforcement is equally useless.
      - Balanced command: humanity with iron discipline is the sure road to victory.
      - Habitual training: commands constantly enforced yield discipline; neglect yields bad discipline.
      - Mutual confidence: a general who trusts his men and insists on obedience wins mutual gain.
  - Chapters IX–X · II
    - Kinds of Ground
      - Accessible ground: seize raised sunny spots first and guard supply lines.
      - Entangling ground: attack only if enemy is unprepared; retreat becomes impossible after failure.
      - Temporizing ground: ignore bait, withdraw, then strike when part of the enemy commits.
      - Narrow passes: garrison them first; if enemy fully holds one, do not pursue.
      - Precipitous heights: occupy sunny heights first; if enemy holds them, retreat and entice.
      - Distant positions: with equal strength, provoking battle from afar works to your disadvantage.
    - Six Calamities
      - Flight: hurling one force against ten times its size.
      - Insubordination: soldiers too strong and officers too weak.
      - Collapse: officers too strong and soldiers too weak.
      - Ruin: angry subordinates fight on their own before the commander decides.
      - Disorganization: weak authority, unclear orders, and no fixed duties.
      - Rout: misjudging enemy strength and failing to place picked soldiers in front.
    - Command Principles
      - Terrain as ally: ground aids the general, but estimating the enemy and distances tests greatness.
      - Fight only for victory: fight despite the ruler’s order if victory is sure; refuse if not.
      - Jewel of the kingdom: advance without coveting fame, retreat without fearing disgrace.
      - Soldiers as sons: treat them like children and they will follow into danger and death.
      - Spoiled children: indulgence without authority and kindness without command make troops useless.
    - Conditions for Complete Victory
      - Know yourself and the enemy: knowing only one side brings victory halfway.
      - Know the ground: terrain may make even a sound attack impracticable.
      - Experienced general: once in motion, never bewildered; once camp is broken, never at a loss.
      - Complete knowledge: know enemy, self, Heaven, and Earth to make victory complete.
- XI. The Nine Situations
  - XI. The Nine Situations · I
    - The Nine Varieties of Ground
      - Dispersive and facile ground: home soil or shallow penetration; troops inclined to scatter or retreat
      - Contentious and open ground: positions worth seizing or free movement; advantage goes to the first holder
      - Intersecting highways and serious ground: key to three states or deep in hostile country; control or plunder matters
      - Difficult, hemmed-in, desperate ground: harsh terrain, narrow defiles, or no escape but fighting
    - Right Response to Each Ground
      - Dispersive, facile, contentious ground: fight not, halt not, attack not — avoid premature commitment
      - Open and intersecting-highway ground: do not block the enemy; join hands with allies
      - Serious and difficult ground: gather in plunder; keep steadily on the march
      - Hemmed-in and desperate ground: resort to stratagem; fight without delay when escape is impossible
    - Unbalancing the Enemy
      - Dislocate the enemy: wedge between front and rear, large and small units, officers and men
      - Keep the enemy's united forces in disorder
      - Advance only when advantage exists; otherwise stay still
      - Seize what the enemy holds dear to make him amenable
    - Rapidity Is the Essence of War
      - Rapidity is the essence of war: exploit unreadiness, unexpected routes, unguarded spots
      - Ssu-ma I's eight-day march: crushed a revolt before fortifications or reinforcements could form
      - Li Ching's flooded-river descent: sudden appearance, like thunder, made the rebel surrender
    - Principles for the Invading Force
      - Deep penetration builds solidarity: the further in, the more united troops become
      - Foray in fertile country to supply the army with food
      - Nurture troops, do not overtax them; conserve energy and devise unfathomable plans
      - Keep the army moving so the enemy never fixes your position
      - No-escape positions make soldiers prefer death to flight and achieve anything
  - XI. The Nine Situations · II
    - Desperate Straits and Morale
      - Desperate straits: soldiers lose fear, stand firm, and fight hardest when no refuge remains.
      - Self-command: without marshaling they stay alert; without orders they obey and can be trusted.
      - No omens: forbid divination and superstitious doubts; then no calamity is feared.
      - Wealth and life: soldiers part with both because they have no choice, not from distaste.
      - Tears before battle: grief marks resolve; at bay, troops fight with the courage of Chu and Kuei.
    - Unity as a Living Organism
      - Shuai-jan snake: head, tail, and middle all respond to attack as one living body.
      - Same boat: even enemies cooperate when caught in a storm; an army must do likewise.
      - No mechanical bonds: tethering horses and burying wheels cannot stop flight; unity of purpose can.
      - Level courage: set one standard of courage so all ranks share the same resolution.
      - Ground and strength: proper use of ground lets strong and weak both serve effectively.
      - One man: the skillful general moves his army as if leading a single person by the hand.
    - The General's Hidden Hand
      - Quiet and upright: secrecy preserves plans; justice maintains order.
      - Mystify your own men: use false reports and appearances to keep troops in ignorance.
      - Change constantly: alter plans, shift camps, take circuitous routes to bewilder the enemy.
      - Kick away the ladder: commit troops beyond recall, burn boats, and drive men like sheep.
      - Into danger: after mobilization, lose no time in striking at the enemy’s heart.
    - Responses for the Nine Grounds
      - Nine situations: adapt measures to all nine grounds; study expediency and human nature.
      - Depth and cohesion: penetrating deeply binds troops; short penetration disperses them.
      - Dispersive and facile: inspire unity; keep army parts closely connected.
      - Contentious and open: hurry up the rear; keep vigilant defenses.
      - Intersecting and serious: consolidate alliances; maintain continuous supplies.
      - Difficult and hemmed-in: push along the road; block retreat to force desperation.
  - XI. The Nine Situations · III
    - Desperate Ground and Soldier Psychology
      - Desperate ground: proclaim the hopelessness of survival; only then soldiers fight to the death.
      - Soldier's nature: surrounded, they resist; cornered, they fight hard; in danger, they obey.
      - Deadly peril: armies survive when escape is impossible; desperate straits produce safety.
      - Harm's way: a force fallen into danger is precisely the one capable of victory.
    - Strategic Independence and Pressure
      - Attacking the strong: prevent concentration of enemy forces; overawe opponents so allies cannot join.
      - Avoid alliances: do not foster other states; pursue secret designs with awe-inspiring prestige.
      - Secret statecraft: capture cities and overthrow kingdoms by independent cunning, not entangling coalitions.
      - Intelligence basics: know neighbors' designs, terrain features, and use local guides before moving.
      - Warlike prince: ignorance of four or five such principles disqualifies him from command.
    - Secrecy and Command Control
      - Rewards and orders: grant rewards unpredictably, issue orders unconstrained by prior arrangements; handle an army as one man.
      - Deed over design: confront soldiers with the act itself; never reveal the deeper plan.
      - News management: display bright prospects; tell troops nothing when the outlook is gloomy.
      - Seal the frontiers: block passes, destroy tallies, stop emissaries when taking command.
      - Stern in council: dominate the council-chamber to control the situation.
    - Adapting to the Enemy
      - Accommodate the enemy: fall in with his purpose to make him careless; then deliver your attack.
      - Flank and wait: hang persistently on the enemy's flank; in the long run kill his commander by sheer cunning.
      - Exploit openings: if the enemy leaves a door open, rush in immediately.
      - Seize what he prizes: forestall him by taking what he holds dear; cajole him into arriving when you choose.
      - Rule and adaptation: walk the path defined by rule, yet bend to the enemy until the decisive battle.
  - XI. The Nine Situations · IV
    - The Maiden’s Guile
      - Feigned passivity: Open by appearing timid and harmless to lower enemy vigilance.
      - Patience as tactic: Withhold true capability until the enemy exposes a vulnerable opening.
      - Deception precedes action: The enemy’s misreading of your posture creates the conditions for advantage.
      - Control of perception: How you appear matters more than what you intend, until the moment to strike.
    - The Hare’s Burst
      - Sudden transformation: Once the opening appears, abandon all pretense and act instantly.
      - Speed defeats response: Rapid movement denies the enemy time to organize opposition.
      - Commitment, not hesitation: After commitment, there is no room for timidity — only acceleration.
      - The hare’s meaning: Speed, not timidity; the image is for pursuit, not escape.
    - Strategic Rhythm
      - Phased tempo: Slow, quiet preparation; then explosive execution — a deliberate sequence.
      - Enemy’s dilemma: By the time intentions are clear, opposition is already impossible.
      - Economy of force: The opening is created by prior disguise, not by prolonged struggle.
      - One complete maneuver: All strategy compresses into two moments — wait, then strike.

  - Chapters XII–XIII · I
    - The Five Uses of Fire
      - Five fire attacks: burn soldiers in camp, stores, baggage trains, arsenals, or drop fire on the enemy.
      - Preparation: keep fire-raising materials ready and await dry weather and rising-wind days.
      - Wind rules: start fires to windward; never attack from the leeward side.
      - Fire vs. water: fire shows intelligence and destroys; water only intercepts and cannot strip an enemy.
    - Responding to Fire's Developments
      - Fire inside the camp: strike at once with an attack from outside.
      - Enemy remains calm: do not attack; bide your time.
      - Flames at height: follow up if practicable; otherwise hold your position.
      - External ignition: if you can burn from outside, do not wait for an outbreak within.
      - Watch the signs: calculate the stars and keep watch for the proper days.
    - Enterprise and Restraint
      - Cultivate enterprise: without it, battles and attacks end in waste and stagnation.
      - Advantage only: move not unless you see an advantage; fight not unless the position is critical.
      - No pique: no ruler should field troops to gratify his spleen; no general should fight from vexation.
      - Irreversibility: anger changes to gladness, but a destroyed kingdom and the dead never return.
      - Leadership: the enlightened ruler plans ahead; the good general cultivates his resources.
  - Chapters XII–XIII · II
    - War’s True Cost
      - Ignorance is costly: a war dragging on for years outweighs any sum spent on spies.
      - Grudging spy money: the height of inhumanity—unfit for leader, sovereign, or victory.
      - Foreknowledge decides: wise rulers and generals strike and conquer through knowing the enemy.
      - Only from men: foreknowledge cannot come from spirits, analogy, or calculation.
    - Five Classes of Spies
      - Local spies: inhabitants of the enemy’s district, won over by kind treatment.
      - Inward spies: enemy officials subverted through grievance, greed, or ambition.
      - Converted spies: enemy agents captured, bribed, and turned to one’s own service.
      - Doomed spies: own agents fed false plans, sent to deceive and be sacrificed.
      - Surviving spies: ordinary agents who bring back news from the enemy camp.
    - Managing the Spy Network
      - Intimate trust: spies share the general’s closest confidence, even his tent.
      - Liberal reward: no one is paid more; no business kept more secret.
      - Leader’s qualities: intuitive sagacity, benevolence, and subtlety are required.
      - Leak discipline: a spy who divulges plans too early dies with the recipient.
      - First targets: identify the enemy general’s aides, guards, and sentries through spies.
    - The Converted Spy as Pivot
      - Seek and convert: enemy spies must be tempted, housed, and won over.
      - Force multiplier: converted spies enable recruiting local and inward spies.
      - Deception channel: through them, doomed spies carry false tidings to the enemy.
      - Timing: surviving spies act on appointed occasions using their information.
      - Utmost liberality: the converted spy is essential, so treat him generously.
    - Historical Proof
      - I Chih: served the Hsia and enabled the rise of Yin.
      - Lu Ya: served the Yin and enabled the rise of Chou.
      - Divine manipulation: five spies working unseen is the sovereign’s most precious faculty.
      - Eyes and ears: an army without spies cannot move or see.
Core Conclusion and Practical Takeaways
- Core Strategic Principles
  - Supreme excellence: break the enemy's resistance without fighting; win by stratagem before bloodshed.
  - Know self and enemy: full knowledge yields lasting confidence; half knowledge gives half victory; none brings defeat.
  - Rapidity is war's essence: exploit unreadiness, take unexpected routes, and never let war drag on.
  - Adapt like water: avoid strength, strike weakness, and never repeat a winning tactic.
  - Invincibility first: make yourself undefeatable, then wait for the enemy's moment of vulnerability.
  - Seize the initiative: arrive first, impose your will, and march where the enemy is undefended.
- Daily Practices
  - Temple calculations: weigh the five factors and seven comparisons before committing to any plan.
  - Prepare readiness: rely on your own preparation, not on the enemy's absence or on chance.
  - Deceive deliberately: feign incapacity, entice, irritate, and divide to strike where the enemy is unprepared.
  - Invest in intelligence: spend freely on spies; true foreknowledge comes only from human sources.
  - Conserve and forage: use enemy provisions, reward first captors, and integrate surrendered strength.
  - Train constantly: commands enforced habitually yield discipline; neglected commands yield chaos.
- Leadership and Command
  - General as bulwark: a complete commander strengthens the state; a defective one invites ruin.
  - Balance humanity and iron discipline: treat soldiers as children, but never spoil them into uselessness.
  - Avoid the five faults: recklessness, cowardice, hot temper, sensitivity to shame, and over-solicitude for men.
  - Command without interference: a free hand wins; sovereign meddling hobbles the army and shakes confidence.
  - Unify the spirit: make the whole force respond like the shuai-jan snake, all parts acting as one body.
  - Lead without self-interest: advance without coveting fame, retreat without fearing disgrace.
- Mindset Shifts
  - Victory precedes battle: seek battle only after victory has been made certain by preparation.
  - Defeat is self-inflicted: security lies in your own hands; the enemy only supplies the opportunity.
  - Fight for advantage, not anger: never field troops to gratify a ruler's spleen or a general's vexation.
  - Momentum beats heroics: combine energy, timing, and terrain rather than demanding superhuman effort.
  - Constraint creates resolve: troops fight hardest when escape is impossible; desperate ground can yield safety.
  - Control perception: keep plans dark, mystify your own men, and reveal intent only at the strike.
- Practical Application
  - Negotiate from calculation: settle strategy before engagement, as temple deliberations decide victory.
  - Choose the battleground: avoid costly sieges; attack where the opponent must respond or is weakest.
  - Mine misfortune for advantage: in difficulty, actively seek the benefit hidden within the danger.
  - Know what to refuse: some roads, armies, towns, positions, and even sovereign commands must be disobeyed.
  - Prefer whole victories: capture states and forces intact; a destructive triumph is an inferior triumph.

- Tactical Variation and Terrain (VII–X)
  - Maneuvering difficulty: winding routes, forced marches, and supply lines decide arrival and survival.
  - Command unity: gongs, drums, banners focus a host; brave or coward cannot act alone.
  - Advantages of variation: refuse some roads, armies, towns, commands; blend gain and danger.
  - Terrain reading: camp by mountains, rivers, marshes, plains; read birds, dust, and troop behavior.
  - Six calamities: flight, insubordination, collapse, ruin, disorganization, rout stem from poor command.

Deep Dive
- Introduction
  - Introduction · I
    - The Biographical Record
      - Ssu-ma Ch'ien's account: Sun Tzu, a native of Ch'i, served King Ho Lu of Wu.
      - The concubine test: 180 women drilled; he beheaded the king's favorites to enforce discipline.
      - Command doctrine: unclear orders blame the general; clear orders disobeyed blame the officers.
      - Proven in war: Sun Tzu defeated Ch'u, entered Ying, and awed Ch'i and Chin.
    - The Case for Skepticism
      - Tso Chuan silence: the greatest contemporary record never mentions Sun Wu as general or author.
      - Yeh Shui-hsin's attack: lesser figures are recorded, so omitting so brilliant a general is incredible.
      - Anachronism argument: professional generals did not exist before the Warring States period.
      - Forgery hypothesis: the book may be a later private scholar's work, not applied by Wu.
      - Concubine story dismissed: the experiment on palace women is "utterly preposterous and incredible."
    - Evidence for the Work's Antiquity
      - Widespread quotation: Wu Ch'i and Huai-nan Tzu plagiarize it, placing it before the 5th century B.C.
      - Archaic vocabulary: obsolete word meanings confirm an early textual date.
      - Internal markers: references to old land-tenure, armored chariots, and Wu as a living state.
      - Skeptic's concession: even Yeh dates the style to the early fifth century.
    - Textual History
      - Ts'ao Ts'ao's preface: Sun Tzu's work is the profoundest on war; his age missed its essential purport.
      - The 82 chapters: Han Shu lists an expanded corpus, but Ssu-ma Ch'ien knew only the 13.
      - Accretion theory: apocryphal writings collected under Sun Tzu's name; later bibliographies prove it.
      - Authentic core: the 13 chapters existed in Ssu-ma Ch'ien's time essentially as we have them now.
  - Introduction · II
    - Authorship and Historical Dating
      - Yeh Shui-hsin's theory: untenable; text reflects a practical soldier's observation and experience.
      - Two internal references: to Wu-Yueh enmity, not Ch'u, pointing to late dates.
      - Ch'u absent: Sun Tzu's 13 chapters never mention Ch'u, Wu's great enemy before 506 B.C.
      - Composition window: likely 505-496 B.C. if written for Ho Lu; could be later if not.
      - Author's status: not eminent; Tso Chuan's silence outweighs Shih Chi's account.
    - Historical Legend and Reconstruction
      - Legend's origin: book's celebrity may have created mythical biography for its author.
      - Capture of Ying: greatest feat of Ho Lu's reign, later credited to Sun Wu by popular identification.
      - Conjectured life: entered Wu service about Ho Lu's accession, subordinate officer, present at Ying.
      - Yueh's attack: convinced him the upstart kingdom was the future great enemy.
      - Irony: China's most illustrious man of peace contemporary with its greatest war writer.
    - Textual Transmission
      - Early text: Ssu-ma Ch'ien's 13 chapters essentially same as extant.
      - Ts'ao Kung: first commentator, no ground to suppose he tampered with text.
      - Standard edition: Chi T'ien-pao's Sung collection became sole field; lost then rediscovered.
      - Sun Hsing-yen's recension: compared older T'ung Tien and T'ai P'ing Yü Lan versions to restore text.
      - Result: "standard text" is closest approximation to Sun Tzu's original work.
    - The Eleven Commentators
      - Ts'ao Ts'ao (Ts'ao Kung): austere, compressed notes; characteristic of the stern commander.
      - Meng Shih and Chia Lin: meager and scanty; dates uncertain, least valuable.
      - Li Ch'uan and Tu Yu: Li's notes short and pointed; Tu Yu's from T'ung Tien, repeats predecessors.
      - Tu Mu: copious notes with historical parallels; summary of gist: benevolence plus artifice.
      - Ch'en Hao and Mei Yao-ch'en: Ch'en attacks Tu Mu; Mei's commentary praised by Ou-yang Hsiu.
  - Introduction · III
    - The Commentators
      - Sun Wu's style: terse diction, deep meaning, strict logical sequence, obscured by later critics.
      - Mei Yao-ch'en: best commentator; brushed aside old prejudices and restored the true meaning.
      - Wang Hsi: original but untrustworthy; his readings compare poorly with Ts'ao Kung's.
      - Ho Yen-hsi: supplies helpful additions and copious extracts from dynastic histories.
      - Chang Yu: lucid master of exposition, expanding Ts'ao Kung's cryptic sentences.
      - Sung florescence: military commentary boomed after frontier defeats in 1038–42.
    - Appreciations
      - Great generals: Han Hsin, Feng I, Lu Meng and Yo Fei all studied Sun Tzu with enthusiasm.
      - Literary praise: Su Hsun and Cheng Hou ranked Sun Tzu above the revered classics.
      - Cheng Hou's verdict: terse yet elegant, simple yet profound, perspicuous and practical.
      - Chu Hsi's caveat: this high praise risks encouraging unrelenting warfare and militarism.
    - Apologies for War
      - China's paradox: endless clash of arms, yet mainstream sentiment from Lao Tzu downward was pacifist.
      - Ssu-ma Ch'ien: weapons are the Sage's means to punish cruelty, calm turmoil, and rescue the imperiled.
      - Tu Mu: war is punishment, a function of government, no different in kind from flogging.
      - Civil-military split: scholars' shame about war made them lose sight of fundamental principles.
      - Confucius armed: though saying "I never studied armies," he used force at Chia-ku and conquered.
    - Answering Objections
      - Study completed by practice: Chao Kua's defeat condemns half-learning, not military theory.
      - Guile is lawful: war's treacherous nature demands stratagem; even Confucius broke an extorted oath.
      - Sun Hsing-yen: Confucius's "I am unversed" means only that he did not specialize in war.
      - Leaders must learn war: one who commands armies needs Sun Tzu's art; victory belongs to practiced generals.
- Chapters I–IV
  - Chapters I–IV · I
    - I. Laying Plans
      - War's gravity: vital to the state; a road to safety or ruin; never to be neglected.
      - Five factors: Moral Law, Heaven, Earth, Commander, and Method and discipline govern all strategic deliberation.
      - Moral Law and Commander: people united with the ruler; commander embodies wisdom, sincerity, benevolence, courage, strictness.
      - Seven comparisons: moral law, ability, terrain, discipline, strength, training, and consistent rewards forecast victory or defeat.
      - Deception as essence: feign inability or distance; entice, irritate, divide; strike where unprepared.
      - Calculations: many temple deliberations beforehand lead to victory; few or none lead to defeat.
    - II. Waging War
      - Cost of war: an army of 100,000 costs a thousand ounces of silver daily; protraction exhausts the state.
      - Perils of delay: weapons dull, ardor dampens, strength drains, and rivals seize the advantage.
      - Speed over cleverness: no country has benefited from prolonged war; victory demands rapid conclusion.
      - Forage on the enemy: one cartload of enemy provisions equals twenty of one's own in saved transport.
      - Rewards and integration: reward first captors, replace enemy flags, treat prisoners kindly, and use the conquered to augment strength.
      - General's burden: the leader of armies is arbiter of the people's fate, peace, or peril.
  - Chapters I–IV · II
    - The Supreme Victory
      - Take whole, not shattered: capture the enemy's state and forces intact; destruction is inferior.
      - Supreme excellence: break the enemy's resistance without fighting; conquest by stratagem, not bloodshed.
      - Victory without loss: dispute mastery of the Empire with forces intact; triumph complete.
    - Hierarchy of Strategies
      - Best: balk the enemy's plans with active counter-attack, not passive defense.
      - Next: prevent the junction of enemy forces, isolating them from allies.
      - Lesser: attack the enemy's army in the field.
      - Worst: besiege walled cities; costly and slow.
    - The Folly of Sieges
      - Avoid sieges: mantlets, movable shelters, and mounds take months to prepare.
      - Impatient assault: enraged general sends men like ants; one-third slain, town untaken.
      - Skillful capture: subdue troops without fighting, capture cities without siege, overthrow kingdoms without lengthy operations.
    - Force Ratios and Engagement
      - Ten to one: surround the enemy.
      - Five to one: attack directly.
      - Two to one: divide forces to strike front and rear.
      - Equal or slightly inferior: offer battle if able; otherwise avoid, or flee if utterly unequal.
      - Small force in stubborn fight: will be captured by the larger force in the end.
    - The General and the State
      - General is bulwark: if complete, State strong; if defective, State weak.
      - Ruler's first error: commanding advance or retreat while ignorant the army cannot obey — hobbling it.
      - Ruler's second error: governing an army as a kingdom — causes restlessness.
      - Ruler's third error: employing officers without discrimination — shakes soldiers' confidence.
      - Anarchy flings victory away: restless and distrustful army invites trouble from other princes.
    - Five Essentials and Knowing Self and Enemy
      - Know when to fight: wins who attacks or defends at the right time.
      - Handle superior and inferior forces: adapt through locality and timing.
      - Unity of spirit: army animated by the same spirit throughout all ranks wins.
      - Preparedness: prepared self waits to take the enemy unprepared.
      - No sovereign interference: general with military capacity and free command wins.
      - Know enemy and self: know both, fear no hundred battles; know one, win and lose; know neither, succumb every battle.
  - Chapters I–IV · III
    - The Primacy of Invincibility
      - Invincibility first: good fighters make themselves undefeatable, then await the enemy's moment of vulnerability.
      - Defeat is self-made: securing against defeat lies in your own hands; the enemy supplies the opportunity for victory.
      - Knowing vs doing: you may know how to conquer without being able to do it.
      - No mistakes: victories come from making no blunders, conquering an enemy already defeated.
    - Defense and Offense
      - Defensive tactics: security against defeat; chosen when strength is insufficient.
      - Offensive tactics: ability to defeat the enemy; chosen when strength is superabundant.
      - Skilled defense: hides in the earth's secret recesses so the enemy cannot locate him.
      - Skilled attack: flashes from the heights like a thunderbolt, giving the enemy no time to prepare.
    - The Invisible Victory
      - True excellence: winning before the common herd sees victory, without public acclaim.
      - Winning with ease: the clever fighter excels in easy conquest, not in hard-fought battles.
      - No reputation: victories over unseen circumstances earn neither wisdom's fame nor courage's credit.
      - Bloodless triumph: the enemy submits before bloodshed, so the world never knows the deed.
    - Victory Before Battle
      - Battle after victory: the victorious strategist seeks battle only after victory has been won.
      - Defeat's path: the destined loser fights first, then looks for victory.
      - Moral law and method: the consummate leader cultivates moral law, method, and discipline to control success.
      - Position as preparation: all arrangements and precautions make defeat impossible and enable the right moment.
    - The Five Calculations
      - Five terms: Measurement, Estimation of quantity, Calculation, Balancing of chances, Victory.
      - Chain of dependence: Earth gives Measurement; Measurement gives Estimation; Estimation gives Calculation; Calculation gives Balancing; Balancing gives Victory.
      - Comparative weight: a victorious army outweighs a routed one like a pound against a grain.
      - Irresistible force: a conquering army's onrush is like pent-up waters bursting into a thousand-fathom chasm.
- Chapters V–VI
  - Chapters V–VI · I
    - Organization and Control
      - Dividing numbers: large forces are controlled like small ones by breaking into subordinate units.
      - Signs and signals: coordinating a host in battle is a matter of agreed communications.
      - Direct and indirect maneuvers keep the whole array unshaken against attack.
    - Direct and Indirect Maneuver
      - Chêng and ch’i: direct force fixes the enemy; indirect force wins victory.
      - Endless combinations: five notes, colors, and tastes yield infinite variations; two maneuvers likewise.
      - Mutual interchange: direct and indirect lead into each other like a circle, inexhaustible.
      - Surprise flips to direct: once the enemy perceives an indirect move, it becomes direct.
    - Energy and Timing
      - Onset like a torrent: momentum rolls stones along, crushing what stands before it.
      - Decision like a falcon: strike at the measured instant, with self-restraint and timing.
      - Crossbow and trigger: energy is stored in formation; decision releases it suddenly.
      - Terrible onset, prompt decision are the marks of the good fighter.
    - Concealment and Deception
      - Simulated disorder requires perfect discipline underneath.
      - Feigned fear requires real courage; feigned weakness requires real strength.
      - Deceptive appearances keep the enemy moving; sacrifice baits to lure him.
      - Lying in wait: tempting baits plus picked troops ambush the pursuing enemy.
    - Combined Momentum
      - Use combined energy, not excessive demands on individual soldiers.
      - Logs and stones: on level ground they rest; on a slope they roll; round shapes descend.
      - Momentum of round stone rolled from a mountain height gives victory with small forces.
  - Chapters V–VI · II
    - Seize the Initiative
      - First in the field: arrive fresh and await the enemy; force him to hasten and arrive exhausted.
      - Impose your will: fight on your own terms or not at all; lure or damage to control the enemy's movements.
      - Harass and provoke: disturb an enemy at ease, starve the well-supplied, and force the encamped to move.
      - March where undefended: move through unguarded country and appear at points where you are not expected.
    - Attack Weakness, Defense Impenetrable
      - Attack undefended places: success is certain when the enemy cannot defend; hold positions that cannot be attacked.
      - Subtlety and secrecy: by becoming invisible and inaudible, you hold the enemy's fate in your hands.
      - Irresistible advance and safe retreat: strike weak points; retire more rapidly than the enemy can pursue.
      - Force or avoid battle: attack a place the enemy must relieve to bring him to fight; baffle him to prevent engagement.
    - Concentrate While Dividing the Enemy
      - Keep forces united: visible enemy dispositions plus our own invisibility let us concentrate while the enemy disperses.
      - Whole against fractions: pit many against few by compelling the enemy to prepare at several points.
      - Reinforcement creates weakness: strengthening the van weakens the rear; spreading forces everywhere makes them weak everywhere.
      - Numerical strength is relative: weakness comes from preparing against attacks; strength comes from forcing the enemy to prepare against ours.
      - Fix time and place: concentration from afar wins; uncertainty leaves wings, van, and rear unable to support each other.
    - Discover the Enemy
      - Victory despite numbers: if the enemy ignores time and place, superior numbers will not save him.
      - Rouse and test: provoke the enemy to reveal activity or inactivity; force him to expose his vulnerable spots.
      - Compare strengths: know where the opposing army is superabundant and where it is deficient.
      - Victory is invisible: all see the tactics of conquest, but none see the strategy from which victory evolves.
    - Be Like Water
      - Avoid strength, strike weakness: as water flows downhill, war avoids the strong and attacks the weak.
      - No constant shape: adapt tactics to the foe as water adapts its course to the ground.
      - Never repeat tactics: let methods be regulated by infinite variety; the heaven-born captain modifies plans per opponent.
      - Nature's changes: elements, seasons, days, and moon illustrate that warfare has no constant conditions.
- Chapters VII–VIII
  - Chapters VII–VIII · I
    - The Difficulty of Maneuvering
      - Deviation: turn the devious into direct by enticing the enemy away, then reach the goal first.
      - Forced marches: 100 li loses all leaders, 50 li half the force, 30 li two-thirds arrive.
      - Supplies: an army without baggage-train, provisions, or bases of supply is lost.
      - Terrain and allies: know neighbors’ designs, the country’s features, and use local guides before marching.
    - Speed and Disposition
      - Momentum: be swift as wind, compact as forest, ravaging as fire, immovable as mountain.
      - Plans and strikes: keep plans dark as night, then fall like a thunderbolt.
      - Adaptability: concentrate or divide troops according to circumstances; dissimulate to succeed.
      - Spoils: divide plunder fairly and allot conquered territory to soldiers for self-sustaining campaigns.
    - Command and Control
      - Signals: gongs, drums, banners, and flags focus the ears and eyes of the host on one point.
      - Unity: a single body makes it impossible for the brave to advance alone or the cowardly to retreat alone.
      - Day and night: use fire and drums by night, flags and banners by day.
    - Psychology and Timing
      - Spirit and moods: attack when the enemy’s morning keenness has flagged and minds turn homeward.
      - Self-possession: await disorder calmly, stay near while the enemy toils, remain well-fed against famished foes.
      - Circumstances: refuse to intercept orderly banners or attack calm, confident arrays.
    - Rules of Engagement
      - Ground rules: never advance uphill or oppose a downhill enemy.
      - Ruses: do not pursue feigned flight, swallow bait, or block an army returning home.
      - Desperate foe: leave an outlet when surrounding; never press a cornered enemy too hard.
  - Chapters VII–VIII · II
    - The Need for Tactical Variation
      - Tactical variation: the general’s highest art, outranking mere knowledge of terrain or fixed advantages.
      - Ground dictates conduct: no camping in difficult country, ally where roads intersect, do not linger in isolated positions.
      - Extreme situations: use stratagem when hemmed in; fight when desperate.
      - Know what to refuse: some roads, armies, towns, positions, and even sovereign commands must be disobeyed.
      - Variation unlocks knowledge: without it, even topographical grasp and the Five Advantages fail in practice.
    - Blending Advantage and Disadvantage
      - Temper expectation of gain by weighing the enemy’s power to harm you.
      - Balanced counsel lets the essential part of your plan succeed.
      - In difficulty, seek advantage actively; it is the way to extricate yourself from misfortune.
      - Weaken hostile chiefs: damage their assets, keep them engaged, and lure them toward chosen points.
    - Readiness Over Assumption
      - Rely on readiness, not on the enemy’s absence: prepare to receive him and make your position unassailable.
    - Five Dangerous Faults of a General
      - Recklessness invites destruction.
      - Cowardice leads to capture.
      - Hasty temper can be provoked by insults.
      - Sensitivity to shame makes a leader vulnerable to slander.
      - Over-solicitude for men sacrifices military advantage to comfort and brings ruin.
- Chapters IX–X
  - Chapters IX–X · I
    - Camping by Terrain
      - Mountains: pass quickly, camp near valleys in high sunny spots; never fight uphill.
      - Rivers: after crossing, move far from the river; strike when half the enemy has crossed.
      - Marshes: cross them without delay; if forced to fight, keep water, grass, and trees to your rear.
      - Plains: choose accessible ground, high to the right and rear, so danger lies ahead.
      - Dangerous ground: abandon defiles, thickets, quagmires, and crevasses; lure the enemy into them instead.
    - Reading Natural Signs
      - Quiet enemy: close and still means reliance on a strong position.
      - Provocative enemy: keeping aloof and challenging means he wants you to advance.
      - Easy camp: an accessible encampment is a deliberate bait.
      - Wildlife: birds rising signal ambush; startled beasts signal imminent attack.
      - Dust columns: high dust means chariots, low wide dust means infantry, drifting dust means foraging or camping.
    - Reading Troop Behavior
      - Speech: humble words with preparations mean attack; violent words with advance mean retreat.
      - Water and food: thirsty soldiers drink before filling vessels; hungry soldiers lean on spears.
      - Camp signs: night clamor shows fear, shifting banners show sedition, angry officers show worn-out men.
      - Desperate resolve: feeding grain to horses, killing cattle, and abandoning cooking pots mean fight to the death.
      - Exhaustion: seeing an advantage and not taking it proves the soldiers are spent.
      - Envoys: compliments mean truce; peace terms without sworn oaths mean a plot.
    - Command and Discipline
      - Numbers: equal numbers suffice for defense; avoid frontal attack—concentrate, watch, and reinforce.
      - Contempt: the general who scorns his opponents invites capture.
      - Loyalty before punishment: punish before attachment creates useless troops; attachment without enforcement is equally useless.
      - Balanced command: humanity with iron discipline is the sure road to victory.
      - Habitual training: commands constantly enforced yield discipline; neglect yields bad discipline.
      - Mutual confidence: a general who trusts his men and insists on obedience wins mutual gain.
  - Chapters IX–X · II
    - Kinds of Ground
      - Accessible ground: seize raised sunny spots first and guard supply lines.
      - Entangling ground: attack only if enemy is unprepared; retreat becomes impossible after failure.
      - Temporizing ground: ignore bait, withdraw, then strike when part of the enemy commits.
      - Narrow passes: garrison them first; if enemy fully holds one, do not pursue.
      - Precipitous heights: occupy sunny heights first; if enemy holds them, retreat and entice.
      - Distant positions: with equal strength, provoking battle from afar works to your disadvantage.
    - Six Calamities
      - Flight: hurling one force against ten times its size.
      - Insubordination: soldiers too strong and officers too weak.
      - Collapse: officers too strong and soldiers too weak.
      - Ruin: angry subordinates fight on their own before the commander decides.
      - Disorganization: weak authority, unclear orders, and no fixed duties.
      - Rout: misjudging enemy strength and failing to place picked soldiers in front.
    - Command Principles
      - Terrain as ally: ground aids the general, but estimating the enemy and distances tests greatness.
      - Fight only for victory: fight despite the ruler’s order if victory is sure; refuse if not.
      - Jewel of the kingdom: advance without coveting fame, retreat without fearing disgrace.
      - Soldiers as sons: treat them like children and they will follow into danger and death.
      - Spoiled children: indulgence without authority and kindness without command make troops useless.
    - Conditions for Complete Victory
      - Know yourself and the enemy: knowing only one side brings victory halfway.
      - Know the ground: terrain may make even a sound attack impracticable.
      - Experienced general: once in motion, never bewildered; once camp is broken, never at a loss.
      - Complete knowledge: know enemy, self, Heaven, and Earth to make victory complete.
- XI. The Nine Situations
  - XI. The Nine Situations · I
    - The Nine Varieties of Ground
      - Dispersive and facile ground: home soil or shallow penetration; troops inclined to scatter or retreat
      - Contentious and open ground: positions worth seizing or free movement; advantage goes to the first holder
      - Intersecting highways and serious ground: key to three states or deep in hostile country; control or plunder matters
      - Difficult, hemmed-in, desperate ground: harsh terrain, narrow defiles, or no escape but fighting
    - Right Response to Each Ground
      - Dispersive, facile, contentious ground: fight not, halt not, attack not — avoid premature commitment
      - Open and intersecting-highway ground: do not block the enemy; join hands with allies
      - Serious and difficult ground: gather in plunder; keep steadily on the march
      - Hemmed-in and desperate ground: resort to stratagem; fight without delay when escape is impossible
    - Unbalancing the Enemy
      - Dislocate the enemy: wedge between front and rear, large and small units, officers and men
      - Keep the enemy's united forces in disorder
      - Advance only when advantage exists; otherwise stay still
      - Seize what the enemy holds dear to make him amenable
    - Rapidity Is the Essence of War
      - Rapidity is the essence of war: exploit unreadiness, unexpected routes, unguarded spots
      - Ssu-ma I's eight-day march: crushed a revolt before fortifications or reinforcements could form
      - Li Ching's flooded-river descent: sudden appearance, like thunder, made the rebel surrender
    - Principles for the Invading Force
      - Deep penetration builds solidarity: the further in, the more united troops become
      - Foray in fertile country to supply the army with food
      - Nurture troops, do not overtax them; conserve energy and devise unfathomable plans
      - Keep the army moving so the enemy never fixes your position
      - No-escape positions make soldiers prefer death to flight and achieve anything
  - XI. The Nine Situations · II
    - Desperate Straits and Morale
      - Desperate straits: soldiers lose fear, stand firm, and fight hardest when no refuge remains.
      - Self-command: without marshaling they stay alert; without orders they obey and can be trusted.
      - No omens: forbid divination and superstitious doubts; then no calamity is feared.
      - Wealth and life: soldiers part with both because they have no choice, not from distaste.
      - Tears before battle: grief marks resolve; at bay, troops fight with the courage of Chu and Kuei.
    - Unity as a Living Organism
      - Shuai-jan snake: head, tail, and middle all respond to attack as one living body.
      - Same boat: even enemies cooperate when caught in a storm; an army must do likewise.
      - No mechanical bonds: tethering horses and burying wheels cannot stop flight; unity of purpose can.
      - Level courage: set one standard of courage so all ranks share the same resolution.
      - Ground and strength: proper use of ground lets strong and weak both serve effectively.
      - One man: the skillful general moves his army as if leading a single person by the hand.
    - The General's Hidden Hand
      - Quiet and upright: secrecy preserves plans; justice maintains order.
      - Mystify your own men: use false reports and appearances to keep troops in ignorance.
      - Change constantly: alter plans, shift camps, take circuitous routes to bewilder the enemy.
      - Kick away the ladder: commit troops beyond recall, burn boats, and drive men like sheep.
      - Into danger: after mobilization, lose no time in striking at the enemy’s heart.
    - Responses for the Nine Grounds
      - Nine situations: adapt measures to all nine grounds; study expediency and human nature.
      - Depth and cohesion: penetrating deeply binds troops; short penetration disperses them.
      - Dispersive and facile: inspire unity; keep army parts closely connected.
      - Contentious and open: hurry up the rear; keep vigilant defenses.
      - Intersecting and serious: consolidate alliances; maintain continuous supplies.
      - Difficult and hemmed-in: push along the road; block retreat to force desperation.
  - XI. The Nine Situations · III
    - Desperate Ground and Soldier Psychology
      - Desperate ground: proclaim the hopelessness of survival; only then soldiers fight to the death.
      - Soldier's nature: surrounded, they resist; cornered, they fight hard; in danger, they obey.
      - Deadly peril: armies survive when escape is impossible; desperate straits produce safety.
      - Harm's way: a force fallen into danger is precisely the one capable of victory.
    - Strategic Independence and Pressure
      - Attacking the strong: prevent concentration of enemy forces; overawe opponents so allies cannot join.
      - Avoid alliances: do not foster other states; pursue secret designs with awe-inspiring prestige.
      - Secret statecraft: capture cities and overthrow kingdoms by independent cunning, not entangling coalitions.
      - Intelligence basics: know neighbors' designs, terrain features, and use local guides before moving.
      - Warlike prince: ignorance of four or five such principles disqualifies him from command.
    - Secrecy and Command Control
      - Rewards and orders: grant rewards unpredictably, issue orders unconstrained by prior arrangements; handle an army as one man.
      - Deed over design: confront soldiers with the act itself; never reveal the deeper plan.
      - News management: display bright prospects; tell troops nothing when the outlook is gloomy.
      - Seal the frontiers: block passes, destroy tallies, stop emissaries when taking command.
      - Stern in council: dominate the council-chamber to control the situation.
    - Adapting to the Enemy
      - Accommodate the enemy: fall in with his purpose to make him careless; then deliver your attack.
      - Flank and wait: hang persistently on the enemy's flank; in the long run kill his commander by sheer cunning.
      - Exploit openings: if the enemy leaves a door open, rush in immediately.
      - Seize what he prizes: forestall him by taking what he holds dear; cajole him into arriving when you choose.
      - Rule and adaptation: walk the path defined by rule, yet bend to the enemy until the decisive battle.
  - XI. The Nine Situations · IV
    - The Maiden’s Guile
      - Feigned passivity: Open by appearing timid and harmless to lower enemy vigilance.
      - Patience as tactic: Withhold true capability until the enemy exposes a vulnerable opening.
      - Deception precedes action: The enemy’s misreading of your posture creates the conditions for advantage.
      - Control of perception: How you appear matters more than what you intend, until the moment to strike.
    - The Hare’s Burst
      - Sudden transformation: Once the opening appears, abandon all pretense and act instantly.
      - Speed defeats response: Rapid movement denies the enemy time to organize opposition.
      - Commitment, not hesitation: After commitment, there is no room for timidity — only acceleration.
      - The hare’s meaning: Speed, not timidity; the image is for pursuit, not escape.
    - Strategic Rhythm
      - Phased tempo: Slow, quiet preparation; then explosive execution — a deliberate sequence.
      - Enemy’s dilemma: By the time intentions are clear, opposition is already impossible.
      - Economy of force: The opening is created by prior disguise, not by prolonged struggle.
      - One complete maneuver: All strategy compresses into two moments — wait, then strike.
- Chapters XII–XIII
  - Chapters XII–XIII · I
    - The Five Uses of Fire
      - Five fire attacks: burn soldiers in camp, stores, baggage trains, arsenals, or drop fire on the enemy.
      - Preparation: keep fire-raising materials ready and await dry weather and rising-wind days.
      - Wind rules: start fires to windward; never attack from the leeward side.
      - Fire vs. water: fire shows intelligence and destroys; water only intercepts and cannot strip an enemy.
    - Responding to Fire's Developments
      - Fire inside the camp: strike at once with an attack from outside.
      - Enemy remains calm: do not attack; bide your time.
      - Flames at height: follow up if practicable; otherwise hold your position.
      - External ignition: if you can burn from outside, do not wait for an outbreak within.
      - Watch the signs: calculate the stars and keep watch for the proper days.
    - Enterprise and Restraint
      - Cultivate enterprise: without it, battles and attacks end in waste and stagnation.
      - Advantage only: move not unless you see an advantage; fight not unless the position is critical.
      - No pique: no ruler should field troops to gratify his spleen; no general should fight from vexation.
      - Irreversibility: anger changes to gladness, but a destroyed kingdom and the dead never return.
      - Leadership: the enlightened ruler plans ahead; the good general cultivates his resources.
  - Chapters XII–XIII · II
    - War’s True Cost
      - Ignorance is costly: a war dragging on for years outweighs any sum spent on spies.
      - Grudging spy money: the height of inhumanity—unfit for leader, sovereign, or victory.
      - Foreknowledge decides: wise rulers and generals strike and conquer through knowing the enemy.
      - Only from men: foreknowledge cannot come from spirits, analogy, or calculation.
    - Five Classes of Spies
      - Local spies: inhabitants of the enemy’s district, won over by kind treatment.
      - Inward spies: enemy officials subverted through grievance, greed, or ambition.
      - Converted spies: enemy agents captured, bribed, and turned to one’s own service.
      - Doomed spies: own agents fed false plans, sent to deceive and be sacrificed.
      - Surviving spies: ordinary agents who bring back news from the enemy camp.
    - Managing the Spy Network
      - Intimate trust: spies share the general’s closest confidence, even his tent.
      - Liberal reward: no one is paid more; no business kept more secret.
      - Leader’s qualities: intuitive sagacity, benevolence, and subtlety are required.
      - Leak discipline: a spy who divulges plans too early dies with the recipient.
      - First targets: identify the enemy general’s aides, guards, and sentries through spies.
    - The Converted Spy as Pivot
      - Seek and convert: enemy spies must be tempted, housed, and won over.
      - Force multiplier: converted spies enable recruiting local and inward spies.
      - Deception channel: through them, doomed spies carry false tidings to the enemy.
      - Timing: surviving spies act on appointed occasions using their information.
      - Utmost liberality: the converted spy is essential, so treat him generously.
    - Historical Proof
      - I Chih: served the Hsia and enabled the rise of Yin.
      - Lu Ya: served the Yin and enabled the rise of Chou.
      - Divine manipulation: five spies working unseen is the sovereign’s most precious faculty.
      - Eyes and ears: an army without spies cannot move or see.
Core Conclusion and Practical Takeaways
- Core Strategic Principles
  - Supreme excellence: break the enemy's resistance without fighting; win by stratagem before bloodshed.
  - Know self and enemy: full knowledge yields lasting confidence; half knowledge gives half victory; none brings defeat.
  - Rapidity is war's essence: exploit unreadiness, take unexpected routes, and never let war drag on.
  - Adapt like water: avoid strength, strike weakness, and never repeat a winning tactic.
  - Invincibility first: make yourself undefeatable, then wait for the enemy's moment of vulnerability.
  - Seize the initiative: arrive first, impose your will, and march where the enemy is undefended.
- Daily Practices
  - Temple calculations: weigh the five factors and seven comparisons before committing to any plan.
  - Prepare readiness: rely on your own preparation, not on the enemy's absence or on chance.
  - Deceive deliberately: feign incapacity, entice, irritate, and divide to strike where the enemy is unprepared.
  - Invest in intelligence: spend freely on spies; true foreknowledge comes only from human sources.
  - Conserve and forage: use enemy provisions, reward first captors, and integrate surrendered strength.
  - Train constantly: commands enforced habitually yield discipline; neglected commands yield chaos.
- Leadership and Command
  - General as bulwark: a complete commander strengthens the state; a defective one invites ruin.
  - Balance humanity and iron discipline: treat soldiers as children, but never spoil them into uselessness.
  - Avoid the five faults: recklessness, cowardice, hot temper, sensitivity to shame, and over-solicitude for men.
  - Command without interference: a free hand wins; sovereign meddling hobbles the army and shakes confidence.
  - Unify the spirit: make the whole force respond like the shuai-jan snake, all parts acting as one body.
  - Lead without self-interest: advance without coveting fame, retreat without fearing disgrace.
- Mindset Shifts
  - Victory precedes battle: seek battle only after victory has been made certain by preparation.
  - Defeat is self-inflicted: security lies in your own hands; the enemy only supplies the opportunity.
  - Fight for advantage, not anger: never field troops to gratify a ruler's spleen or a general's vexation.
  - Momentum beats heroics: combine energy, timing, and terrain rather than demanding superhuman effort.
  - Constraint creates resolve: troops fight hardest when escape is impossible; desperate ground can yield safety.
  - Control perception: keep plans dark, mystify your own men, and reveal intent only at the strike.
- Practical Application
  - Negotiate from calculation: settle strategy before engagement, as temple deliberations decide victory.
  - Choose the battleground: avoid costly sieges; attack where the opponent must respond or is weakest.
  - Mine misfortune for advantage: in difficulty, actively seek the benefit hidden within the danger.
  - Know what to refuse: some roads, armies, towns, positions, and even sovereign commands must be disobeyed.
  - Prefer whole victories: capture states and forces intact; a destructive triumph is an inferior triumph.
