　Chapter 3 :

　　Offensive Strategy Generally, in war the best policy is to take a state intact; to ruin it is inferior to this. To capture the enemy's entire army is better than to destroy it; to take intact a regiment, a company, or a squad is better than to destroy them. For to win one hundred victories in one hundred battles is not the acme of skill. To subdue the enemy without fighting is the supreme excellence. Thus, what is of supreme importance in war is to attack the enemy's strategy. Next best is to disrupt his alliances by diplomacy. The next best is to attack his army. And the worst policy is to attack cities.Attack cities only when there is no alternative because to prepare big shields and wagons and make ready the necessary arms and equipment require at least three months, and to pile up earthen ramps against the walls requires an additional three months. The general, unable to control his impatience, will order his troops to swarm up the wall like ants, with the result that one-third of them will be killed without taking the city. Such is the calamity of attacking cities. Thus, those skilled in war subdue the enemy's army without battle. They capture the enemy's cities without assaulting them and overthrow his state without protracted operations. Their aim is to take all under heaven intact by strategic considerations. Thus, their troops are not worn out and their gains will be complete. This is the art of offensive strategy. Consequently, the art of using troops is this: When ten to the enemy's one, surround him. When five times his strength, attack him. If double his strength, divide him. If equally matched, you may engage him with some good plan. If weaker numerically, be capable of withdrawing. And if in all respects unequal, be capable of eluding him, for a small force is but booty for one more powerful if it fights recklessly. Now, the general is the assistant to the sovereign of the state. If this assistance is all-embracing, the state will surely be strong; if defective, the state will certainly be weak. Now, there are three ways in which a sovereign can bring misfortune upon his army: When ignorant that the army should not advance, to order anadvance; or when ignorant that it should not retire, to order a retirement. This is described as "hobbling the army." When ignorant of military affairs, to interfere in their administration. This causes the officers to be perplexed. When ignorant of command problems, to interfere with the direction of the fighting. This engenders doubts in the minds of the officers. If the army is confused and suspicious, neighboring rulers will take advantage of this and cause trouble. This is what is meant by: "A confused army leads to another's victory." Thus, there are five points in which victory may be predicted: He who knows when he can fight and when he cannot will be victorious. He who understands how to fight in accordance with the strength of antagonistic forces will be victorious. 　 He whose ranks are united in purpose will be victorious. He who is well prepared and lies in wait for an enemy who is not well prepared will be victorious. He whose generals are able and not interfered with by the sovereign will be victorious. It is in these five matters that the way to victory is known. Therefore, I say: Know your enemy and know yourself; in a hundred battles, you will never be defeated. When you are ignorant of the enemy but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and of yourself, you are sure to be defeated in every battle.

　　Chapter 4 :

　　Dispositions The skillful warriors in ancient times first made themselves invincible and then awaited the enemy's moment of vulnerability. Invincibility depends on oneself, but the enemy' vulnerability on himself. It follows that those skilled in war can make themselves invincible but cannot cause an enemy to be certainly vulnerable. Therefore, it can be said that, one may know how to win, but cannot necessarily do so. Defend yourself when you cannot defeat the enemy, and attack the enemy when you can. One defends when his strangth is inadequate; he attacks when it is abundant. Those who are skilled in defense hide themselves as under the nine-fold earth; those in attack flash forth as from above the ninefold heavens. Thus, they are capable both of protecting themselves and of gaining a complete victory. To foresee a victory which the ordinary man can foresee is not the acme of excellence. Neither is it if you triumph in battle and are universally acclaimed "expert," for to lift an autumn down requires no great strength, to distinguish between the sun and moon is no test of vision, to hear the thunderclap is no indication of acute hearing. In ancient times, those called skilled in war conquered an enemy easily conquered. And, therefore, the victories won by a master of war gain him neither reputation for wisdom nor merit for courage. For he wins his victories without erring. Without erring he establishes the certainty of his victory; he conquers an enemy already defeated. Therefore, the skillful commander takes up a position in which he cannot be defeated and misses no opportunity to overcome him enemy. Thus, a victorious army always seeks battle after his plans indicate that victory is possible under them, whereas an army destined to defeat fights in the hope of winning but without any planning. Those skilled in war cultivate their policies and strictly adhere to the laws and regulations. Thus, it is in their power to control success. Now, the elements of the art of war are first, the measurement of space; second, the estimation of quantities; third, calculations; fourth, comparisons; and fifth, chances of victory. Measurements of space are derived from the ground. Quantities, comparisons from figures, and victory from comparisons. Thus, a victorious army is as one yi balanced against a grain, and a defeated army is as a grain balanced against one yi. It is because of disposition that a victorious general is able to make his soldiers fight with the effect of pent-up waters which, suddenly released, plunge into a bottomless abyss.

　　Chapter 5 :

　　Posture of Army Generally, management of a large force is the same as management of a few men. It is a matter of organization. And to direct a large force is the same as to direct a few men. This is a matter of formations and signals. That the army is certain to sustain the enemy's attack without suffering defeat is due to operations of the extraordinary and the normal forces. Troops thrown against the enemy as a grindstone against eggs is an example of a solid acting upon a void. Generally, in battle, use the normal force to engage and use the extraordinary forces to win. Now, the resources of those skilled in the use of extraordinary forces are as infinite as the heavens and earth, as inexhaustible as the flow of the great rivers, for they end and recommence - cyclical, as are the movements of the sun and moon. They die away and are reborn - recurrent, as are the passing seasons. The musical notes are the passing seasons. The musical notes are only five in number, but their combinations are so infinite that one cannot visualize them all. The flavors are only five in number, but their blends are so various that one cannot taste them all. In battle, there are only the normal and extraordinary forces, but their combinations are limitless; none can comprehend them all. For these two forces are mutually reproductive. It is like moving in an endless circle. Who can exhaust the possibility of their combination? When torrential water tosses boulders, it is because of its momentum; when the strike of a hawk breaks the body of its prey, it is because of timing. Thus, the momentum of one skilled in war is overwhelming, and his attack precisely timed. His potential is that of a fully drawn crossbow; his timing, that of the release of the trigger. In tumult and uproar, the battle seems chaotic, but there must be no disorder in one's own troops. The battlefield may seem in confusion and chaos, but one's array must be in good order. That will be proof against defeat. Apparent confusion is a product of good order; apparent cowardice, of courage; apparent weakness, of strength. Order of disorder depends on organization and direction; courage or cowardice on circumstances; strength or weakness on tactical dispositions. Thus, one who is skilled at making the enemy move does so by creating a situation, according to which the enemy will act. He entices the enemy with something he is certain to want. He keeps the enemy on the move by holding out bait and then attacks him with picked troops. Therefore, a skilled commander seeks victory from the situation and does not demand it of his subordinates. He selects suitable men and exploits the situation. He who utilizes the situation uses his men in fighting as one rolls logs or stones. Now, the nature of logs and stones is that on stable ground they are static; on a slope, they move. If square, they stop; if round, they roll. Thus, the energy of troops skillfully commanded in battle may be compared to the momentum of round boulders which roll down from a mountain thousands of feet in height.

　Chapter 6 :

　　Void and Actuality Generally, he who occupies the field of battle first and awaits his enemy is at ease, and he who comes later to the scene and rushes into the fight is weary. And, therefore, those skilled in war bring the enemy to the field of battle and are not brought there by him. One able to make the enemy come of his own accord does so by offering him some advantage. And one able to stop him from coming does so by preventing him. Thus, when the enemy is at ease, be able to tire him, when well fed, to starve him, when at rest to make him move. Appear at places which he is unable to rescue; move swiftly in a direction where you are least expected. That you may march a thousand li without tiring yourself is because you travel where there is no enemy. To be certain to take what you attack is to attack a place the enemy does not or cannot protect. To be certain to hold what you defend is to defend a place the enemy dares not or is not able to attack. Therefore, against those skilled in attack, the enemy does not know where to defend, and against the experts in defense, the enemy does not know where to attack. How subtle and insubstantial, that the expert leaves no trace. How divinely mysterious, that he is inaudible. Thus, he is master of his enemy's fate. His offensive will be irresistible if he makes for his enemy's weak positions; he cannot be overtaken when he withdraws if he moves swiftly. When I wish o give battle, my enemy, even though protected by high walls and deep moats, cannot help but engage me, for I attack a position he must relieve. When I wish to avoid battle, I may defend myself simply be drawing a line on the ground; the enemy will be unable to attack me because I divert him from going where he wishes. If I am able to determine the enemy's dispositions while, at the same time, I conceal my own, then I can concentrate my forces and his must be divided. And if I concentrate while he divides, I can use my entire strength to attack a fraction of his. Therefore, I will be numerically superior. Then, if I am able to use many to strike few at the selected point, those I deal with will fall into hopeless straits. The enemy must not know where I intend to give battle. For if he does not know where I intend to give battle, he must prepare in a great many places. And when he prepares in a great many places, those I have to fight in will be few. For if he prepares to the front, his rear will be weak, and if to the rear, his front will be fragile. If he strengthens his left, his right will be vulnerable, and if his right, there will be few troops on his left. And when he sends troops everywhere, he will be weak everywhere. Numerical weakness comes from having to guard against possible attacks; numerical strength from forcing the enemy to make these preparations against us. If one knows where and when a battle will be fought, his troops can march a thousand li and meet on the field. But if one knows neither the battleground nor the day of battle, the left will be unable to aid the right and the right will be unable to aid the left, and the van will be unable to support the rear and the rear, the van. How much more is this so when separated by several tens of li or, indeed, be even a few! Although I estimate the troops of Yue as many, of what benefit is this superiority with respect to the outcome of war? Thus, I say that victory can be achieved. For even if the enemy is numerically stronger, I can prevent him from engaging. Therefore, analyze the enemy's plans so that you will know his shortcomings as strong points. Agitate him in order to ascertain the pattern of his movement. Lure him out to reveal his dispositions and ascertain his position. Launch a probing attack in order to learn where his strength is abundant and where deficient. The ultimate in disposing one's troops is to conceal them without ascertainable shape. Then the most penetrating spies cannot pry nor can the wise lay plans against you. It is according to the situations that plans are laid for victory, but the multitude does not comprehend ts. Although everyone can see the outward aspects, none understands how the victory is achieved. Therefore, when a victory is won, one's tactics are not repeated. One should always respond to circumstances in an infinite variety of ways. Now, an army may be likened to water, for just as flowing water avoids the heights and hastens to the lowlands, so an army should avoid strength and strike weakness. And as water shapes its flow in accordance with the ground, so an army manages its victory in accordance with the situation of the enemy. And as water has no constant form, there are in warfare no constant conditions. Thus, one able to win the victory by modifying his tactics in accordance with the enemy situation may be said to be divine. Of the five elements [water, fire, metal, wood, and earth], none is always predominant; of the four seasons, none lasts forever; of the days, some are long and some short, and the moon waxes and wanes. That is also the law of employing troops.

　　Chapter 7 :

　　Manuevering Normally, in war, the general receives his commands from the sovereign. During the process from assembling his troops and mobilizing the people to blending the army into a harmonious entity and encamping it, nothing is more difficult than the art of maneuvering for advantageous positions. What is difficult about it is to make the devious route the most direct routeand divert the enemy by enticing him with a bait. So doing, you may set out after he does and arrive at the battlefield before him. One able to do this shows the knowledge of the artifice of diversion. Therefore, both advantage and danger are inherent in maneuvering for an advantageous position. One who sets the entire army in moriton with impediments to pursue an advantageous position will not attain it. If he abandons the camp and all the impediments to contend for advantage, the stores will be lost. Thus, if one orders his men to make forced marches without armor, stopping neithe day nor night, covering double the usual distance at a stretch, and doing a hundred li to wrest an advantage, it is probable that the commanders will be captured. The stronger men will arrive first and the feeble ones will struggle along behind; so, if this method is used, only one-tenth of the army will reach its destination. In a forced march of fifty li, the commander of the van will probably fall, but half the army will arrive. Ina forced march of thirty li, just two-thirds will arrive. It follows that an army which lacks heavy equipment, fodder, food, and stores will be lost. One who is not acquainted with the designs of his neighbors should not enter into aliances with them. Those who do not know the conditions of mountains and forests, hazardous defiles, marshes and swamps, cannot conduct the march of an army. Those who do not use local guides are unable to obtain the advantages of the ground. Now, war is based on deception. Move when it is advantageous and create changes in the situation by dispersal and concentration of forces,. When campainging, be swift as the wind; in leisurely marching, majestic as the forest; in raiding and plundering, be fierce as fire; in standing, firm as the mountains. When hiding, be as unfathomable as things behind the clouds; when moving, fall like a thunderbolt. When you plunder the countryside, divide your forces. When you conquer territory, defend strategic points. Weigh the situation before you move. He who knows the artifice of diversion will be victorious. Such is the art of manuevering.

孙子兵法中英文对照 《孫子兵法》計篇第一

孫子曰：兵者，國之大事，死生之地，存亡之道，不可不察也。

故經之以五，校之以計，而索其情：一曰道，二曰天，三曰地，四曰將，五曰法。道者，令民于上同意者也，可與之死，可與之生，民不詭也。天者，陰陽、寒暑、時制也。地者，高下、遠近、險易、廣狹、死生也。將者，智、信、仁、勇、嚴也。法者，曲制、官道、主用也。凡此五者，將莫不聞，知之者勝，不知之者不勝。故校之以計，而索其情。曰：主孰有道？將孰有能？天地孰得？法令孰行？兵眾孰強？士卒孰練？賞罰孰明？吾以此知勝負矣。

將聽吾計，用之必勝，留之﹔將不聽吾計，用之必敗，去之。

計利以聽，乃為之勢，以佐其外。勢者，因利而制權也。

兵者，詭道也。故能而示之不能，用而示之不用，近而示之遠，遠而示之近。利而誘之，亂而取之，實而備之，強而避之，怒而撓之，卑而驕之，佚而勞之，親而離之，攻其不備，出其不意。此兵家之勝，不可先傳也。

夫未戰而廟算勝者，得算多也﹔未戰而廟算不勝者，得算少也。多算勝，少算不勝，而況無算乎！吾以此觀之，勝負見矣。

I. LAYING PLANS

1. Sun Tzu said: The art of war is of vital importance to the State.

2. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected.

3. The art of war, then, is governed by five constant factors, to be taken into account in one's deliberations, when seeking to determine the conditions obtaining in the field.

4. These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Commander; (5) Method and discipline.

5,6. The Moral Law causes the people to be in complete accord with their ruler, so that they will follow him regardless of their lives, undismayed by any danger.

7. Heaven signifies night and day, cold and heat, times and seasons.

8. Earth comprises distances, great and small; danger and security; open ground and narrow passes; the chances of life and death.

9. The Commander stands for the virtues of wisdom, sincerity, benevolence, courage and strictness.

10. By method and discipline are to be understood the marshaling of the army in its proper subdivisions,    the graduations of rank among the officers, the maintenance of roads by which supplies may reach the army, and the control of military expenditure.

11. These five heads should be familiar to every general: he who knows them will be victorious; he who knows them not will fail.

12. Therefore, in your deliberations, when seeking to determine the military conditions, let them be made the basis of a comparison, in this wise:

13. (1) Which of the two sovereigns is imbued with the Moral law? (2) Which of the two generals has most ability? (3) With whom lie the advantages derived from Heaven and Earth? (4) On which side is discipline most rigorously enforced? (5) Which army is stronger? (6) On which side are officers and men more highly trained? (7) In which army is there the greater constancy both in reward and punishment?

14. By means of these seven considerations I can forecast victory or defeat.

15. The general that hearkens to my counsel and acts upon it will conquer: let such a one be retained in command! The general that hearkens not to my counsel nor acts upon it will suffer defeat: let such a one be dismissed!

16. While heading the profit of my counsel, avail yourself also of any helpful circumstances over and beyond the ordinary rules.

17. According as circumstances are favorable, one should modify one's plans.

18. All warfare is based on deception.

19. Hence, when able to attack, we must seem unable; when using our forces, we must seem inactive; when we are near, we must make the enemy believe we are far away; when far away, we must make him believe we are near.

20. Hold out baits to entice the enemy. Feign disorder, and crush him.

21. If he is secure at all points, be prepared for him. If he is in superior strength, evade him.

22. If your opponent is of choleric temper, seek to irritate him. Pretend to be weak, that he may grow arrogant.

23. If he is taking his ease, give him no rest. If his forces are united, separate them.

24. Attack him where he is unprepared, appear where you are not expected.

25. These military devices, leading to victory, must not be divulged beforehand.

26. Now the general who wins a battle makes many calculations in his temple ere the battle is fought.
The general who loses a battle makes but few calculations beforehand. Thus do many calculations lead to victory and few calculations to defeat: how much more no calculation at all! It is by attention to this point that I can foresee who is likely to win or lose.


02《孫子兵法》作戰篇第二　　　　　　　　　　　　　　　　

孫子曰：凡用兵之法，馳車千駟，革車千乘，帶甲十萬，千里饋糧，則內外之費，賓客之用，膠漆之材，車甲之奉，日費千金，然後十萬之師舉矣。其用戰也貴勝，久則鈍兵挫銳，攻城則力屈，久暴師則國用不足。夫鈍兵挫銳，屈力殫貨，則諸侯乘其弊而起，雖有智者，不能善其後矣。故兵聞拙速，未睹巧之久也。夫兵久而國利者，未之有也。故不盡知用兵之害者，則不能盡知用兵之利也。

善用兵者，役不再籍，糧不三載﹔取用于國，因糧于敵，故軍食可足也。

國之貧于師者遠輸，遠輸則百姓貧。近師者貴賣，貴賣則百姓竭，財竭則急於丘役。力屈、財殫，中原內虛于家。百姓之費，十去其七﹔公家之費：破軍罷馬，甲冑矢弩，戟盾蔽櫓，丘牛大車，十去其六。

故智將務食于敵。食敵一鐘，當吾二十鐘﹔箕杆一石，當吾二十石。

故殺敵者，怒也﹔取敵之利者，貨也。故車戰，得車十乘已上，賞其先得者，而更其旌旗，車雜而乘之，卒善而養之，是謂勝敵而益強。

故兵貴勝，不貴久。

故知兵之將，民之司命，國家安危之主也。

II. WAGING WAR
1. Sun Tzu said: In the operations of war, where there are in the field a thousand swift chariots, as many heavy chariots, and a hundred thousand mail-clad soldiers, with provisions enough to carry them a thousand li, the expenditure at home and at the front, including entertainment of guests, small items such as glue and paint, and sums spent on chariots and armor, will reach the total of a thousand ounces of silver per day. Such is the cost of raising an army of 100,000 men.

2. When you engage in actual fighting, if victory is long in coming, then men's weapons will grow dull and their ardor will be damped. If you lay siege to a town, you will exhaust your strength.

3. Again, if the campaign is protracted, the resources of the State will not be equal to the strain.

4. Now, when your weapons are dulled, your ardor damped, your strength exhausted and your treasure spent, other chieftains will spring up to take advantage of your extremity. Then no man, however wise, will be able to avert the consequences that must ensue.

5. Thus, though we have heard of stupid haste in war, cleverness has never been seen associated with long delays.

6. There is no instance of a country having benefited from prolonged warfare.

7. It is only one who is thoroughly acquainted with the evils of war that can thoroughly understand the profitable way of carrying it on.

8. The skillful soldier does not raise a second levy, neither are his supply-wagons loaded more than twice.

9. Bring war material with you from home, but forage on the enemy. Thus the army will have food enough for its needs.

10. Poverty of the State exchequer causes an army to be maintained by contributions from a distance. Contributing to maintain an army at a distance causes the people to be impoverished.

11. On the other hand, the proximity of an army causes prices to go up; and high prices cause the people's substance to be drained away.

12. When their substance is drained away, the peasantry will be afflicted by heavy exactions.

13,14. With this loss of substance and exhaustion of strength, the homes of the people will be stripped bare, and three-tenths of their income will be dissipated; while government expenses for broken chariots, worn-out horses, breast-plates and helmets, bows and arrows, spears and shields, protective mantles, draught-oxen and heavy wagons, will amount to four-tenths of its total revenue.

15. Hence a wise general makes a point of foraging on the enemy. One cartload of the enemy's provisions is equivalent to twenty of one's own, and likewise a single picul of his provender is equivalent to twenty from one's own store.

16. Now in order to kill the enemy, our men must be roused to anger; that there may be advantage from defeating the enemy, they must have their rewards.

17. Therefore in chariot fighting, when ten or more chariots have been taken, those should be rewarded who took the first. Our own flags should be substituted for those of the enemy, and the chariots mingled and used in conjunction with ours. The captured soldiers should be kindly treated and kept.

18. This is called, using the conquered foe to augment one's own strength.

19. In war, then, let your great object be victory, not lengthy campaigns.

20. Thus it may be known that the leader of armies is the arbiter of the people's fate, the man on whom it depends whether the nation shall be in peace or in peril.
?

03《孫子兵法》謀攻篇第三　　　　　　　　　　　　　　　　

孫子曰：凡用兵之法，全國為上，破國次之﹔全軍為上，破軍次之﹔全旅為上，破旅次之﹔全卒為上，破卒次之﹔全伍為上，破伍次之。是故百戰百勝，非善之善也﹔不戰而屈人之兵，善之善者也。

故上兵伐謀，其次伐交，其次伐兵，其下攻城。攻城之法為不得已。修櫓轒轀、具器械、三月而後成，距闉，又三月而後已。將不勝其忿，而蟻附之，殺士三分之一，而城不拔者，此攻之災也。故善用兵者，屈人之兵而非戰也。拔人之城而非攻也，破人之國而非久也，必以全爭于天下，故兵不頓，而利可全，此謀攻之法也。

故用兵之法，十則圍之，五則攻之，倍則分之，敵則能戰之，少則能逃之，不若則能避之。故小敵之堅，大敵之擒也。

夫將者，國之輔也。輔周則國必強，輔隙則國必弱。

故君之所以患于軍者三：不知軍之不可以進而謂之進，不知軍之不可以退而謂之退，是為縻軍﹔不知三軍之事，而同三軍之政者，則軍士惑矣﹔不知三軍之權，而同三軍之任，則軍士疑矣。三軍既惑且疑，則諸侯之難至矣，是謂亂軍引勝。

故知勝有五：知可以戰與不可以戰者勝，識眾寡之用者勝，上下同欲者勝，以虞待不虞者勝，將能而君不御者勝。此五者，知勝之道也。

故曰：知己知彼，百戰不貽﹔不知彼而知己，一勝一負﹔不知彼不知己，每戰必貽。

III. ATTACK BY STRATAGEM

1. Sun Tzu said: In the practical art of war, the best thing of all is to take the enemy's country whole and intact; to shatter and destroy it is not so good. So, too, it is better to recapture an army entire than to destroy it, to capture a regiment, a detachment or a company entire than to destroy them.

2. Hence to fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.

3. Thus the highest form of generalship is to balk the enemy's plans; the next best is to prevent the junction of the enemy's forces; the next in order is to attack the enemy's army in the field; and the worst policy of all is to besiege walled cities.

4. The rule is, not to besiege walled cities if it can possibly be avoided. The preparation of mantlets, movable shelters, and various implements of war, will take up three whole months; and the piling up of mounds over against the walls will take three months more.

5. The general, unable to control his irritation, will launch his men to the assault like swarming ants, with the result that one-third of his men are slain, while the town still remains untaken. Such are the disastrous effects of a siege.

6. Therefore the skillful leader subdues the enemy's troops without any fighting; he captures their cities without laying siege to them; he overthrows their kingdom without lengthy operations in the field.

7. With his forces intact he will dispute the mastery of the Empire, and thus, without losing a man, his triumph will be complete. This is the method of attacking by stratagem.

8. It is the rule in war, if our forces are ten to the enemy's one, to surround him; if five to one, to attack him; if twice as numerous, to divide our army into two.

9. If equally matched, we can offer battle; if slightly inferior in numbers, we can avoid the enemy; if quite unequal in every way, we can flee from him.

10. Hence, though an obstinate fight may be made by a small force, in the end it must be captured by the larger force.

11. Now the general is the bulwark of the State; if the bulwark is complete at all points; the State will be strong; if the bulwark is defective, the State will be weak.

12. There are three ways in which a ruler can bring misfortune upon his army:

13. (1) By commanding the army to advance or to retreat, being ignorant of the fact that it cannot obey. This is called hobbling the army.

14. (2) By attempting to govern an army in the same way as he administers a kingdom, being ignorant of the conditions which obtain in an army. This causes restlessness in the soldier's minds.

15. (3) By employing the officers of his army without discrimination, through ignorance of the military principle of adaptation to circumstances. This shakes the confidence of the soldiers.

16. But when the army is restless and distrustful, trouble is sure to come from the other feudal princes. This is simply bringing anarchy into the army, and flinging victory away.

17. Thus we may know that there are five essentials for victory: (1) He will win who knows when to fight and when not to fight. (2) He will win who knows how to handle both superior and inferior forces. (3) He will win whose army is animated by the same spirit throughout all its ranks. (4) He will win who, prepared himself, waits to take the enemy unprepared. (5) He will win who has military capacity and is not interfered with by the sovereign.

18. Hence the saying: If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle.
?
04《孫子兵法》形篇第四　　　　　　　　　　　　　　　　　　

孫子曰：昔之善戰者，先為不可勝，以侍敵之可勝。不可勝在己，可勝在敵。故善戰者，能為不可勝，不能使敵之必可勝。故曰：勝可知，而不可為。不可勝者，守也﹔可勝者，攻也。守則不足，攻則有餘。善守者，藏于九地之下﹔善攻者，動于九天之上。故能自保而全勝也。

見勝不過眾人之所知，非善之善者也﹔戰勝而天下曰善，非善之善者也。故舉秋毫不為多力，見日月不為明目，聞雷霆不為聰耳。古之所謂善戰者，勝于易勝者也。故善戰之勝也，無智名，無勇功。故其戰勝不忒。不忒者，其所措必勝，勝已敗者也。故善戰者，立于不敗之地，而不失敵之敗也。是故勝兵先勝而後求戰，敗兵先戰而後求勝。善用兵者，修道而保法，故能為勝敗之政。

兵法：一曰度，二曰量，三曰數，四曰稱，五曰勝。地生度，度生量，量生數，數生稱，稱生勝。

故勝兵若以鎰稱銖，敗兵若以銖稱鎰。

勝者之戰民也，若決積水于千仞之谿者，形也。

IV. TACTICAL DISPOSITIONS

1. Sun Tzu said: The good fighters of old first put themselves beyond the possibility of defeat, and then waited for an opportunity of defeating the enemy.

2. To secure ourselves against defeat lies in our own hands, but the opportunity of defeating the enemy is provided by the enemy himself.

3. Thus the good fighter is able to secure himself against defeat, but cannot make certain of defeating the enemy.

4. Hence the saying: One may know how to conquer without being able to do it.

5. Security against defeat implies defensive tactics; ability to defeat the enemy means taking the offensive.

6. Standing on the defensive indicates insufficient strength; attacking, a superabundance of strength.

7. The general who is skilled in defense hides in the most secret recesses of the earth; he who is skilled in attack flashes forth from the topmost heights of heaven. Thus on the one hand we have ability to protect ourselves; on the other, a victory that is complete.

8. To see victory only when it is within the ken of the common herd is not the acme of excellence.

9. Neither is it the acme of excellence if you fight and conquer and the whole Empire says, "Well done!"

10. To lift an autumn hair is no sign of great strength; to see the sun and moon is no sign of sharp sight; to hear the noise of thunder is no sign of a quick ear.

11. What the ancients called a clever fighter is one who not only wins, but excels in winning with ease.

12. Hence his victories bring him neither reputation for wisdom nor credit for courage.

13. He wins his battles by making no mistakes. Making no mistakes is what establishes the certainty of victory, for it means conquering an enemy that is already defeated.

14. Hence the skillful fighter puts himself into a position which makes defeat impossible, and does not miss the moment for defeating the enemy.

15. Thus it is that in war the victorious strategist only seeks battle after the victory has been won, whereas he who is destined to defeat first fights and afterwards looks for victory.

16. The consummate leader cultivates the moral law, and strictly adheres to method and discipline; thus it is in his power to control success.

17. In respect of military method, we have, firstly, Measurement; secondly, Estimation of quantity; thirdly, Calculation; fourthly, Balancing of chances; fifthly, Victory.

18. Measurement owes its existence to Earth; Estimation of quantity to Measurement; Calculation to Estimation of quantity; Balancing of chances to Calculation; and Victory to Balancing of chances.

19. A victorious army opposed to a routed one, is as a pound's weight placed in the scale against a single grain.

20. The onrush of a conquering force is like the bursting of pent-up waters into a chasm a thousand fathoms deep.

孙子兵法中英文对照  《孫子兵法》勢篇第五　　　　　　　　　　　　　　　　　　

孫子曰：凡治眾如治寡，分數是也﹔鬥眾如鬥寡，形名是也﹔三軍之眾，可使必受敵而無敗，奇正是也﹔兵之所加，如以碫投卵者，虛實是也。

凡戰者，以正合，以奇勝。故善出奇者，無窮如天地，不竭如江河。終而復始，日月是也。死而復生，四時是也。聲不過五，五聲之變，不可勝聽也。色不過五，五色之變，不可勝觀也。味不過五，五味之變，不可勝嘗也。戰勢不過奇正，奇正之變，不可勝窮之也。奇正相生，如環之無端，孰能窮之？

激水之疾，至于漂石者，勢也﹔鷙鳥之疾，至于毀折者，節也。是故善戰者，其勢險，其節短。勢如張弩，節如發機。

紛紛紜紜，鬥亂而不可亂也。渾渾沌沌，形圓而不可敗也。

亂生于治，怯生于勇，弱生于強。治亂，數也﹔勇怯，勢也﹔強弱，形也。

故善動敵者，形之，敵必從之﹔予之，敵必取之。以利動之，以卒動之。

故善戰者，求之于勢，不責于人，故能擇人而任勢。任勢者，其戰人也，如轉木石。木石之性，安則靜，危則動，方則止，圓則行。故善戰人之勢，如轉圓石于千仞之山者，勢也。

V. ENERGY

1. Sun Tzu said: The control of a large force is the same principle as the control of a few men: it is merely a question of dividing up their numbers.

2. Fighting with a large army under your command is nowise different from fighting with a small one: it is merely a question of instituting signs and signals.

3. To ensure that your whole host may withstand the brunt of the enemy's attack and remain unshaken this is affected by maneuvers direct and indirect.

4. That the impact of your army may be like a grindstone dashed against an egg. This is effected by the science of weak points and strong.

5. In all fighting, the direct method may be used for joining battle, but indirect methods will be needed in order to secure victory.

6. Indirect tactics, efficiently applied, are inexhaustible as Heaven and Earth, unending as the flow of rivers and streams; like the sun and moon, they end but to begin anew; like the four seasons, they pass away to return once more.

7. There are not more than five musical notes, yet the combinations of these five give rise to more melodies than can ever be heard.

8. There are not more than five primary colors (blue, yellow, red, white, and black), yet in combination they produce more hues than can ever been seen.

9. There are not more than five cardinal tastes (sour, acrid, salt, sweet, bitter), yet combinations of them yield more flavors than can ever be tasted.

10. In battle, there are not more than two methods of attack, the direct and the indirect; yet these two in combination give rise to an endless series of maneuvers.

11. The direct and the indirect lead on to each other in turn. It is like moving in a circle. You never come to an end. Who can exhaust the possibilities of their combination?

12. The onset of troops is like the rush of a torrent which will even roll stones along in its course.

13. The quality of decision is like the well-timed swoop of a falcon which enables it to strike and destroy its victim.

14. Therefore the good fighter will be terrible in his onset, and prompt in his decision.

15. Energy may be likened to the bending of a crossbow; decision, to the releasing of a trigger.

16. Amid the turmoil and tumult of battle, there may be seeming disorder and yet no real disorder at all; amid confusion and chaos, your array may be without head or tail, yet it will be proof against defeat.

17. Simulated disorder postulates perfect discipline, simulated fear postulates courage; simulated weakness postulates strength.

18. Hiding order beneath the cloak of disorder is simply a question of subdivision; concealing courage under a show of timidity presupposes a fund of latent energy; masking strength with weakness is to be effected by tactical dispositions.

19. Thus one who is skillful at keeping the enemy on the move maintains deceitful appearances, according to which the enemy will act. He sacrifices something that the enemy may snatch at it.

20. By holding out baits, he keeps him on the march; then with a body of picked men he lies in wait for him.

21. The clever combatant looks to the effect of combined energy, and does not require too much from individuals. Hence his ability to pick out the right men and utilize combined energy.

22. When he utilizes combined energy, his fighting men become as it were like unto rolling logs or stones. For it is the nature of a log or stone to remain motionless on level ground, and to move when on a slope; if four-cornered, to come to a standstill, but if round-shaped, to go rolling down.

23. Thus the energy developed by good fighting men is as the momentum of a round stone rolled down a mountain thousands of feet in height. So much on the subject of energy.

06《孫子兵法》虛實篇第六　　　　　　　　　　　　　　　　

孫子曰：凡先處戰地而待敵者佚，後處戰地而趨戰者勞。故善戰者，致人而不致于人。

能使敵自至者，利之也﹔能使敵不得至者，害之也。故敵佚能勞之，飽能飢之，安能動之。

出其所不趨，趨其所不意。行千里而不勞者，行于無人之地也。攻而必取者，攻其所不守也。守而必固者，守其所不攻也。

故善攻者，敵不知其所守。善守者，敵不知其所攻。

微乎微乎，至于無形，神乎神乎，至于無聲，故能為敵之司命。

進而不可御者，沖其虛也﹔退而不可追者，速而不可及也。故我欲戰，敵雖高壘深溝，不得不與我戰者，攻其所必救也﹔我不欲戰，雖畫地而守之，敵不得與我戰者，乖其所之也。

故形人而我無形，則我專而敵分﹔我專為一，敵分為十，是以十攻其一也，則我眾而敵寡﹔能以眾擊寡者，則吾之所與戰者，約矣。吾所與戰之地不可知，不可知，則敵所備者多，敵所備者多，則吾之所戰者，寡矣。

故備前則後寡，備後則前寡，故備左則右寡，備右則左寡，無所不備，則無所不寡。寡者備人者也，眾者使人備己者也。

故知戰之地，知戰之日，則可千里而會戰。不知戰之地，不知戰之日，則左不能救右，右不能救左，前不能救後，後不能救前，而況遠者數十里，近者數里乎？

以吾度之，越人之兵雖多，亦奚益于勝敗哉？！

故曰：勝可為也。敵雖眾，可使無鬥。

故策之而知得失之計，作之而知動靜之理，形之而知死生之地，角之而知有餘不足之處。

故形兵之極，至于無形﹔無形，則深間不能窺，智者不能謀。

因形而錯勝于眾，眾不能知﹔人皆知我所以勝之形，而莫知吾所以制勝之形。故其戰勝不復，而應形于無窮。

夫兵形象水，水之形避高而趨下，兵之形，避實而擊虛，水因地而制流，兵應敵而制勝。故兵無常勢，水無常形，能因敵變化而取勝者，謂之神。

故五行無常勝，四時無常位，日有短長，月有死生。


VI. WEAK POINTS AND STRONG

1. Sun Tzu said: Whoever is first in the field and awaits the coming of the enemy, will be fresh for the fight; whoever is second in the field and has to hasten to battle will arrive exhausted.

2. Therefore the clever combatant imposes his will on the enemy, but does not allow the enemy's will to be imposed on him.

3. By holding out advantages to him, he can cause the enemy to approach of his own accord; or, by inflicting damage, he can make it impossible for the enemy to draw near.

4. If the enemy is taking his ease, he can harass him; if well supplied with food, he can starve him out; if quietly encamped, he can force him to move.

5. Appear at points which the enemy must hasten to defend; march swiftly to places where you are not expected.

6. An army may march great distances without distress, if it marches through country where the enemy is not.

7. You can be sure of succeeding in your attacks if you only attack places which are undefended. You can ensure the safety of your defense if you only hold positions that cannot be attacked.

8. Hence that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.

9. O divine art of subtlety and secrecy! Through you we learn to be invisible, through you inaudible; and hence we can hold the enemy's fate in our hands.

10. You may advance and be absolutely irresistible, if you make for the enemy's weak points; you may retire and be safe from pursuit if your movements are more rapid than those of the enemy.

11. If we wish to fight, the enemy can be forced to an engagement even though he be sheltered behind a high rampart and a deep ditch. All we need do is attack some other place that he will be obliged to relieve.

12. If we do not wish to fight, we can prevent the enemy from engaging us even though the lines of our encampment be merely traced out on the ground. All we need do is to throw something odd and unaccountable in his way.

13. By discovering the enemy's dispositions and remaining invisible ourselves, we can keep our forces concentrated, while the enemy's must be divided.

14. We can form a single united body, while the enemy must split up into fractions. Hence there will be a whole pitted against separate parts of a whole, which means that we shall be many to the enemy's few.

15. And if we are able thus to attack an inferior force with a superior one, our opponents will be in dire straits.

16. The spot where we intend to fight must not be made known; for then the enemy will have to prepare against a possible attack at several different points; and his forces being thus distributed in many directions, the numbers we shall have to face at any given point will be proportionately few.

17. For should the enemy strengthen his van, he will weaken his rear; should he strengthen his rear, he will weaken his van; should he strengthen his left, he will weaken his right; should he strengthen his right, he will weaken his left. If he sends reinforcements everywhere, he will everywhere be weak.

18. Numerical weakness comes from having to prepare against possible attacks; numerical strength, from compelling our adversary to make these preparations against us.

19. Knowing the place and the time of the coming battle, we may concentrate from the greatest distances in order to fight.

20. But if neither time nor place be known, then the left wing will be impotent to succor the right, the right equally impotent to succor the left, the van unable to relieve the rear, or the rear to support the van. How much more so if the furthest portions of the army are anything under a hundred LI apart, and even the nearest are separated by several LI!

21. Though according to my estimate the soldiers of Yueh exceed our own in number, that shall advantage them nothing in the matter of victory. I say then that victory can be achieved.

22. Though the enemy be stronger in numbers, we may prevent him from fighting. Scheme so as to discover his plans and the likelihood of their success.

23. Rouse him, and learn the principle of his activity or inactivity. Force him to reveal himself, so as to find out his vulnerable spots.

24. Carefully compare the opposing army with your own, so that you may know where strength is superabundant and where it is deficient.

25. In making tactical dispositions, the highest pitch you can attain is to conceal them; conceal your dispositions, and you will be safe from the prying of the subtlest spies, from the machinations of the wisest brains.

26. How victory may be produced for them out of the enemy's own tactics--that is what the multitude cannot comprehend.

27. All men can see the tactics whereby I conquer, but what none can see is the strategy out of which victory is evolved.

28. Do not repeat the tactics which have gained you one victory, but let your methods be regulated by the infinite variety of circumstances.

29. Military tactics are like unto water; for water in its natural course runs away from high places and hastens downwards.

30. So in war, the way is to avoid what is strong and to strike at what is weak.

31. Water shapes its course according to the nature of the ground over which it flows; the soldier works out his victory in relation to the foe whom he is facing.

32. Therefore, just as water retains no constant shape, so in warfare there are no constant conditions.

33. He who can modify his tactics in relation to his opponent and thereby succeed in winning, may be called a heaven-born captain.

34. The five elements (water, fire, wood, metal, earth) are not always equally predominant; the four seasons make way for each other in turn. There are short days and long; the moon has its periods of waning and waxing.

07《孫子兵法》軍爭篇第七　　　　　　　　　　　　　　　　

孫子曰：凡用兵之法，將受命于君，合軍聚眾，交和而舍，莫難于軍爭。軍爭之難者，以迂為直，以患為利。故迂其途，而誘之以利，後人發，先人至，此知迂直之計者也。

故軍爭為利，軍爭為危。舉軍而爭利，則不及﹔委軍而爭利，則輜重捐。是故卷甲而趨，日夜不處，倍道兼行，百里而爭利，則擒三將軍，勁者先，疲者後，其法十一而至﹔五十里而爭利，則蹶上將軍，其法半至﹔三十里而爭利，則三分之二至。是故軍無輜重則亡，無糧食則亡，無委積則亡。

故不知諸侯之謀者，不能豫交﹔不知山林、險阻、沮澤之形者，不能行軍﹔不用鄉導者，不能得地利。

故兵以詐立，以利動，以分和為變者也。

故其疾如風，其徐如林，侵掠如火，不動如山，難知如陰，動如雷震。

掠鄉分眾，廓地分守，懸權而動。

先知迂直之計者勝，此軍爭之法也。

軍政曰：「言不相聞，故為金鼓；視而不見，故為旌旗。」夫金鼓旌旗者，所以一人之耳目也；人既專一， 則勇者不得獨進，怯者不得獨退，此用眾之法也。故夜戰多火鼓，晝戰多旌旗，所以變人之耳目也。

故三軍可奪氣，將軍可奪心。是故朝氣銳，晝氣惰，暮氣歸。故善用兵者，避其銳氣，擊其惰歸，此治氣者也。以治待亂，以靜待嘩，此治心者也。以近待遠，以佚待勞，以飽待飢，此治力者也。無邀正正之旗，無擊堂堂之陣，此治變者也。

故用兵之法，高陵勿向，背丘勿逆，佯北勿從，銳卒勿攻，餌兵勿食，歸師勿遏，圍師遺闕，窮寇勿迫，此用兵之法也。

VII. MANEUVERING

1. Sun Tzu said: In war, the general receives his commands from the sovereign.

2. Having collected an army and concentrated his forces, he must blend and harmonize the different elements thereof before pitching his camp.

3. After that, comes tactical maneuvering, than which there is nothing more difficult. The difficulty of tactical maneuvering consists in turning the devious into the direct, and misfortune into gain.

4. Thus, to take a long and circuitous route, after enticing the enemy out of the way, and though starting after him, to contrive to reach the goal before him, shows knowledge of the artifice of DEVIATION.

5. Maneuvering with an army is advantageous; with an undisciplined multitude, most dangerous.

6. If you set a fully equipped army in march in order to snatch an advantage, the chances are that you will be too late. On the other hand, to detach a flying column for the purpose involves the sacrifice of its baggage and stores.

7. Thus, if you order your men to roll up their buff-coats, and make forced marches without halting day or night, covering double the usual distance at a stretch, doing a hundred LI in order to wrest an vantage, the leaders of all your three divisions will fall into the hands of the enemy.

8. The stronger men will be in front, the jaded ones will fall behind, and on this plan only one-tenth of your army will reach its destination.

9. If you march fifty LI in order to outmaneuver the enemy, you will lose the leader of your first division, and only half your force will reach the goal.

10. If you march thirty LI with the same object, two-thirds of your army will arrive.

11. We may take it then that an army without its baggage-train is lost; without provisions it is lost; without bases of supply it is lost.

12. We cannot enter into alliances until we are acquainted with the designs of our neighbors.

13. We are not fit to lead an army on the march unless we are familiar with the face of the country—its mountains and forests, its pitfalls and precipices, its marshes and swamps.

14. We shall be unable to turn natural advantage to account unless we make use of local guides.

15. In war, practice dissimulation, and you will succeed.

16. Whether to concentrate or to divide your troops, it must be decided by circumstances.

17. Let your rapidity be that of the wind, your compactness that of the forest.

18. In raiding and plundering be like fire, is immovability like a mountain.

19. Let your plans be dark and impenetrable as night, and when you move, fall like a thunderbolt.

20. When you plunder a countryside, let the spoil be divided amongst your men; when you capture new territory, cut it up into allotments for the benefit of the soldiery.

21. Ponder and deliberate before you make a move.

22. He will conquer who has learnt the artifice of deviation. Such is the art of maneuvering.

23. The Book of Army Management says: On the field of battle, the spoken word does not carry far enough: hence the institution of gongs and drums. Nor can ordinary objects be seen clearly enough: hence the institution of banners and flags.

24. Gongs and drums, banners and flags, are means whereby the ears and eyes of the host may be focused on one particular point.

25. The host thus forming a single united body, is it impossible either for the brave to advance alone, or for the cowardly to retreat alone. This is the art of handling large masses of men.

26. In night-fighting, then, make much use of signal-fires and drums, and in fighting by day, of flags and banners, as a means of influencing the ears and eyes of your army.

27. A whole army may be robbed of its spirit; a commander-in-chief may be robbed of his presence of mind.

28. Now a soldier's spirit is keenest in the morning; by noonday it has begun to flag; and in the evening, his mind is bent only on returning to camp.

29. A clever general, therefore, avoids an army when its spirit is keen, but attacks it when it is sluggish and inclined to return. This is the art of studying moods.

30. Disciplined and calm, to await the appearance of disorder and hubbub amongst the enemy: this is the art of retaining self-possession.

31. To be near the goal while the enemy is still far from it, to wait at ease while the enemy is toiling and struggling, to be well-fed while the enemy is famished:--this is the art of husbanding one's strength.

32. To refrain from intercepting an enemy whose banners are in perfect order, to refrain from attacking an army drawn up in calm and confident array: this is the art of studying circumstances.

33. It is a military axiom not to advance uphill against the enemy, nor to oppose him when he comes downhill.

34. Do not pursue an enemy who simulates flight; do not attack soldiers whose temper is keen.

35. Do not swallow bait offered by the enemy. Do not interfere with an army that is returning home.

36. When you surround an army, leave an outlet free. Do not press a desperate foe too hard.

37. Such is the art of warfare.




08《孫子兵法》九變篇第八　　　　　　　　　　　　　　　　

孫子曰：凡用兵之法，將受命于君，合軍聚眾，圮地無舍，衢地交和，絕地勿留，圍地則謀，死地則戰。

途有所不由，軍有所不擊，城有所不攻，地有所不爭，君命有所不受。

故將通于九變之利者，知用兵矣﹔將不通于九變之利，雖知地形，不能得地之利矣﹔治兵不知九變之朮，雖知地利，不能得人之用矣。

是故智者之慮，必雜于利害。雜于利，而務可信也﹔雜于害，而患可解也。

是故屈諸侯者以害，役諸侯者以業，趨諸侯者以利。

故用兵之法，無恃其不來，恃吾有以待也﹔無恃其不攻，恃吾有所不可攻也。

故將有五危：必死，可殺也﹔必生，可虜也﹔忿速，可侮也﹔廉潔，可辱也﹔愛民，可煩也。凡此五者，將之過也，用兵之災也。覆軍殺將，必以五危，不可不察也。

VIII. VARIATION IN TACTICS

1. Sun Tzu said: In war, the general receives his commands from the sovereign, collects his army and concentrates his forces

2. When in difficult country, do not encamp. In country where high roads intersect, join hands with your allies. Do not linger in dangerously isolated positions. In hemmed-in situations, you must resort to stratagem. In desperate position, you must fight.

3. There are roads which must not be followed, armies which must be not attacked, towns which must be besieged, positions which must not be contested, and commands of the sovereign which must not be obeyed.

4. The general who thoroughly understands the advantages that accompany variation of tactics knows how to handle his troops.

5. The general who does not understand these may be well acquainted with the configuration of the country, yet he will not be able to turn his knowledge to practical account.

6. So, the student of war who is unversed in the art of war of varying his plans, even though he be acquainted with the Five Advantages, will fail to make the best use of his men.

7. Hence in the wise leader's plans, considerations of advantage and of disadvantage will be blended together.

8. If our expectation of advantage be tempered in this way, we may succeed in accomplishing the essential part of our schemes.

9. If, on the other hand, in the midst of difficulties we are always ready to seize an advantage, we may extricate ourselves from misfortune.

10. Reduce the hostile chiefs by inflicting damage on them; and make trouble for them, and keep them constantly engaged; hold out specious allurements, and make them rush to any given point.

11. The art of war teaches us to rely not on the likelihood of the enemy's not coming, but on our own readiness to receive him; not on the chance of his not attacking, but rather on the fact that we have made our position unassailable.

12. There are five dangerous faults which may affect a general:
    (1) Recklessness, which leads to destruction;
    (2) Cowardice, which leads to capture;
    (3) A hasty temper, which can be provoked by insults;
    (4) A delicacy of honor which is sensitive to shame;
    (5) Over-solicitude for his men, which exposes him to worry and trouble.

13. These are the five besetting sins of a general, ruinous to the conduct of war.

14. When an army is overthrown and its leader slain, the cause will surely be found among these five dangerous faults. Let them be a subject of meditation.
