course with reference to the enemy.]
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.
[Tu Mu says: "If the enemy is the invading party, we can
cut his line of communications and occupy the roads by which he
will have to return; if we are the invaders, we may direct our
attack against the sovereign himself." It is clear that Sun Tzu,
unlike certain generals in the late Boer war, was no believer in
frontal attacks.]
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.
[This extremely concise expression is intelligibly
paraphrased by Chia Lin: "even though we have constructed
neither wall nor ditch." Li Ch`uan says: "we puzzle him by
strange and unusual dispositions;" and Tu Mu finally clinches the
meaning by three illustrative anecdotes--one of Chu-ko Liang, who
when occupying Yang-p`ing and about to be attacked by Ssu-ma I,
suddenly struck his colors, stopped the beating of the drums, and
flung open the city gates, showing only a few men engaged in
sweeping and sprinkling the ground. This unexpected proceeding
had the intended effect; for Ssu-ma I, suspecting an ambush,
actually drew off his army and retreated. What Sun Tzu is
advocating here, therefore, is nothing more nor less than the
timely use of "bluff."]
13. By discovering the enemy's dispositions and remaining
invisible ourselves, we can keep our forces concentrated, while
the enemy's must be divided.
[The conclusion is perhaps not very obvious, but Chang Yu
(after Mei Yao-ch`en) rightly explains it thus: "If the enemy's
dispositions are visible, we can make for him in one body;
whereas, our own dispositions being kept secret, the enemy will
be obliged to divide his forces in order to guard against attack
from every quarter."]
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;
[Sheridan once explained the reason of General Grant's
victories by saying that "while his opponents were kept fully
employed wondering what he was going to do, HE was thinking most
of what he was going to do himself."]
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.
[In Frederick the Great's INSTRUCTIONS TO HIS GENERALS we
read: "A defensive war is apt to betray us into too frequent
detachment. Those generals who have had but little experience
attempt to protect every point, while those who are better
acquainted with their profession, having only the capital object
in view, guard against a decisive blow, and acquiesce in small
misfortunes to avoid greater."]
18. Numerical weakness comes from having to prepare against
possible attacks; numerical strength, from compelling our
adversary to make these preparations against us.
[The highest generalship, in Col. Henderson's words, is "to
compel the enemy to disperse his army, and then to concentrate
superior force against each fraction in turn."]
19. Knowing the place and the time of the coming battle, we
may concentrate from the greatest distances in order to fight.
[What Sun Tzu evidently has in mind is that nice calculation
of distances and that masterly employment of strategy which
enable a general to divide his army for the purpose of a long and
rapid march, and afterwards to effect a junction at precisely the
right spot and the right hour in order to confront the enemy in
overwhelming strength. Among many such successful junctions
which military history records, one of the most dramatic and
decisive was the appearance of Blucher just at the critical
moment on the field of Waterloo.]
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!
[The Chinese of this last sentence is a little lacking in
precision, but the mental picture we are required to draw is
probably that of an army advancing towards a given rendezvous in
separate columns, each of which has orders to be there on a fixed
date. If the general allows the various detachments to proceed
at haphazard, without precise instructions as to the time and
place of meeting, the enemy will be able to annihilate the army
in detail. Chang Yu's note may be worth quoting here: "If we do
not know the place where our opponents mean to concentrate or the
day on which they will join battle, our unity will be forfeited
through our preparations for defense, and the positions we hold
will be insecure. Suddenly happening upon a powerful foe, we
shall be brought to battle in a flurried condition, and no mutual
support will be possible between wings, vanguard or rear,
especially if there is any great distance between the foremost
and hindmost divisions of the army."]
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.
[Alas for these brave words! The long feud between the two
states ended in 473 B.C. with the total defeat of Wu by Kou Chien
and its incorporation in Yueh. This was doubtless long after Sun
Tzu's death. With his present assertion compare IV. ss. 4.
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 making 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 simple. 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.]

ed., vol. II, p. 490.

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.
[I have departed slightly from the traditional
interpretation of Ts`ao Kung, who says: "From the time of
receiving the sovereign's instructions until our encampment over
against the enemy, the tactics to be pursued are most difficult."
It seems to me that the tactics or maneuvers can hardly be said
to begin until the army has sallied forth and encamped, and
Ch`ien Hao's note gives color to this view: "For levying,
concentrating, harmonizing and entrenching an army, there are
plenty of old rules which will serve. The real difficulty comes
when we engage in tactical operations." Tu Yu also observes that
"the great difficulty is to be beforehand with the enemy in
seizing favorable position."]
The difficulty of tactical maneuvering consists in turning the
devious into the direct, and misfortune into gain.
[This sentence contains one of those highly condensed and
somewhat enigmatical expressions of which Sun Tzu is so fond.
This is how it is explained by Ts`ao Kung: "Make it appear that
you are a long way off, then cover the distance rapidly and
arrive on the scene before your opponent." Tu Mu says:
