provisions are too scanty; or the defenders are variance amongst
themselves。〃'
You can ensure the safety of your defense if you only hold
positions that cannot be attacked。
'I。e。; where there are none of the weak points mentioned
above。 There is rather a nice point involved in the
interpretation of this later clause。 Tu Mu; Ch‘en Hao; and Mei
Yao…ch‘en assume the meaning to be: 〃In order to make your
defense quite safe; you must defend EVEN those places that are
not likely to be attacked;〃 and Tu Mu adds: 〃How much more;
then; those that will be attacked。〃 Taken thus; however; the
clause balances less well with the precedingalways a
consideration in the highly antithetical style which is natural
to the Chinese。 Chang Yu; therefore; seems to come nearer the
mark in saying: 〃He who is skilled in attack flashes forth from
the topmost heights of heaven 'see IV。 ss。 7'; making it
impossible for the enemy to guard against him。 This being so;
the places that I shall attack are precisely those that the enemy
cannot defend。。。。 He who is skilled in defense hides in the most
secret recesses of the earth; making it impossible for the enemy
to estimate his whereabouts。 This being so; the places that I
shall hold are precisely those that the enemy cannot attack。〃'
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。
'An aphorism which puts the whole art of war in a nutshell。'
9。 O divine art of subtlety and secrecy! Through you we
learn to be invisible; through you inaudible;
'Literally; 〃without form or sound;〃 but it is said of
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 anecdotesone 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 prepa
