Chang Yu is the only one to point out the seeming discrepancy, which he thus goes on to explain: "In the chapter on Tactical Dispositions it is said, 'One may KNOW how to conquer without being able to DO it,' whereas here we have the statement that 'victory' can be achieved.' The explanation is, that in the former chapter, where the offensive and defensive are under discussion, it is said that if the enemy is fully prepared, one cannot make certain of beating him. But the present passage refers particularly to the soldiers of Yueh who, according to Sun Tzu's calculations, will be kept in ignorance of the time and place of the impending struggle. That is why he says here 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.
[An alternative reading offered by Chia Lin is: "Know beforehand all plans conducive to our success and to the enemy's failure."23. Rouse him, and learn the principle of his activity or inactivity.
[Chang Yu tells us that by noting the joy or anger shown by the enemy on being thus disturbed, we shall be able to conclude whether his policy is to lie low or the reverse. He instances the action of Cho-ku Liang, who sent the scornful present of a woman's head-dress to Ssu-ma I, in order to goad him out of his Fabian tactics.]
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.
[Cf. IV. ss. 6.]
25. In ****** tactical dispositions, the highest pitch you can attain is to conceal them;[The piquancy of the paradox evaporates in translation.
Concealment is perhaps not so much actual invisibility (see supra ss. 9) as "showing no sign" of what you mean to do, of the plans that are formed in your brain.]
conceal your dispositions, and you will be safe from the prying of the subtlest spies, from the machinations of the wisest brains.
[Tu Mu explains: "Though the enemy may have clever and capable officers, they will not be able to lay any plans against us."]
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.
[I.e., everybody can see superficially how a battle is won;what they cannot see is the long series of plans and combinations which has preceded the battle.]
28. Do not repeat the tactics which have gained you one victory, but let your methods be regulated by the infinite variety of circumstances.
[As Wang Hsi sagely remarks: "There is but one root-principle underlying victory, but the tactics which lead up to it are infinite in number." With this compare Col. Henderson: "The rules of strategy are few and ******. They may be learned in a week. They may be taught by familiar illustrations or a dozen diagrams. But such knowledge will no more teach a man to lead an army like Napoleon than a knowledge of grammar will teach him to write like Gibbon."]
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.
[Like water, taking the line of least resistance.]
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;[That is, as Wang Hsi says:"they predominate alternately."]
the four seasons make way for each other in turn.
[Literally, "have no invariable seat."]
There are short days and long; the moon has its periods of waning and waxing.
[Cf. V. ss. 6. The purport of the passage is simply to illustrate the want of fixity in war by the changes constantly taking place in Nature. The comparison is not very happy, however, because the regularity of the phenomena which Sun Tzu mentions is by no means paralleled in war.]

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.
["Chang Yu says: "the establishment of harmony and confidence between the higher and lower ranks before venturing into the field;" and he quotes a saying of Wu Tzu (chap. 1 ad init.): "Without harmony in the State, no military expedition can be undertaken; without harmony in the army, no battle array can be formed." In an historical romance Sun Tzu is represented as saying to Wu Yuan: "As a general rule, those who are waging war should get rid of all the domestic troubles before proceeding to attack the external foe."]
3. After that, comes tactical maneuvering, than which there is nothing more difficult.
