Chapter VII. MANEUVERING
- Sun Tzu said: In war, the general receives his commands from the
sovereign.
- 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."]
- 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 t hat 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 o n the scene before your opponent." Tu
Mu says: "Hoodwink the enemy, so that he may be remiss and leisurely while you
are dashing along with utmost speed." Ho Shih gives a slightly different turn:
"Although you may have difficult ground to traverse and natural obstacles to
encounter this is a drawback which can be turned into actual advantage by
celerity of movement." Signal examples of this saying are afforded by the two
famous passages across the Alps--that of Hannibal, which laid Italy at his
mercy, and that of Napoleon two thousand years later, which resulted in the
great victory of Marengo.]
- 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.
[Tu Mu cites the famous march of Chao She in 270 B.C. to relieve the town
of O-yu, which was closely invested by a Ch`in army. The King of Chao first
consulted Lien P`o on the advisability of attempting a relief, but the latter
thought the distance too great, and the intervening country too rugged and
difficult. His Majesty then turned to Chao She, who fully admitted the
hazardous nature of the march, but finally said: "We shall be like two rats
fighting in a whole--and the pluckier one will win!" S o he left the capital
with his army, but had only gone a distance of 30 LI when he stopped and began
throwing up entrenchments. For 28 days he continued strengthening his
fortifications, and took care that spies should carry the intelligence to the
enemy. The Ch`in general was overjoyed, and attributed his adversary's
tardiness to the fact that the beleaguered city was in the Han State, and thus
not actually part of Chao territory. But the spies had no sooner departed than
Chao She began a forced march lasting for two days and one night, and arrive
on the scene of action with such astonishing rapidity that he was able to
occupy a commanding position on the "North hill" before the enemy had got wind
of his movements. A crushing defeat followed for the Ch`in forces, who were
obliged to raise the siege of O-yu in all haste and retreat across the
border.]
- Maneuvering with an army is advantageous; with an undisciplined multitude,
most dangerous.
[I adopt the reading of the T`UNG TIEN, Cheng Yu-hsien and the T`U SHU,
since they appear to apply the exact nuance required in order to make sense.
The commentators using the standard text take this line to mean that maneuvers
may be profitable, or they may be dangerous: it all depends on the ability of
the general.]
- 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.
[Some of the Chinese text is unintelligible to the Chinese commentators,
who paraphrase the sentence. I submit my own rendering without much
enthusiasm, being convinced that there is some deep-seated corruption in the
text. On the whole, it is clear t hat Sun Tzu does not approve of a lengthy
march being undertaken without supplies. Cf. infra, ss. 11.]
- 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,
[The ordinary day's march, according to Tu Mu, was 30 LI; but on one
occasion, when pursuing Liu Pei, Ts`ao Ts`ao is said to have covered the
incredible distance of 300 _li_ within twenty-four hours.]
doing a hundred LI in order to wrest an advantage, the leaders of all your
three divisions will fall into the hands of the enemy.
- 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.
[The moral is, as Ts`ao Kung and others point out: Don't march a hundred LI
to gain a tactical advantage, either with or without impedimenta. Maneuvers of
this description should be confined to short distances. Stonewall Jackson
said: "The hardships of forced marches are often more painful than the dangers
of battle." He did not often call upon his troops for extraordinary exertions.
It was only when he intended a surprise, or when a rapid retreat was
imperative, that he sacrificed everything for speed. [1] ]
- 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.
[Literally, "the leader of the first division will be TORN AWAY."]
- If you march thirty LI with the same object, two-thirds of your army will
arrive.
[In the T`UNG TIEN is added: "From this we may know the difficulty of
maneuvering."]
- 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.
[I think Sun Tzu meant "stores accumulated in depots." But Tu Yu says
"fodder and the like," Chang Yu says "Goods in general," and Wang Hsi says
"fuel, salt, foodstuffs, etc."]
- We cannot enter into alliances until we are acquainted with the designs of
our neighbors.
- 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.
- We shall be unable to turn natural advantage to account unless we make use
of local guides. [ss. 12-14 are repeated in chap. XI. ss. 52.]
- In war, practice dissimulation, and you will succeed.
[In the tactics of Turenne, deception of the enemy, especially as to the
numerical strength of his troops, took a very prominent position. [2] ]
- Whether to concentrate or to divide your troops, must be decided by
circumstances.
- Let your rapidity be that of the wind,
[The simile is doubly appropriate, because the wind is not only swift but,
as Mei Yao-ch`en points out, "invisible and leaves no tracks."] your
compactness that of the forest.
[Meng Shih comes nearer to the mark in his note: "When slowly marching,
order and ranks must be preserved"--so as to guard against surprise attacks.
But natural forest do not grow in rows, whereas they do generally possess the
quality of density or compactness.]
- In raiding and plundering be like fire, [Cf. SHIH CHING, IV. 3. iv. 6:
"Fierce as a blazing fire which no man can check."] is immovability like a
mountain.
[That is, when holding a position from which the enemy is trying to
dislodge you, or perhaps, as Tu Yu says, when he is trying to entice you into
a trap.]
- Let your plans be dark and impenetrable as night, and when you move, fall
like a thunderbolt.
[Tu Yu quotes a saying of T`ai Kung which has passed into a proverb: "You
cannot shut your ears to the thunder or your eyes to the lighting--so rapid
are they." Likewise, an attack should be made so quickly that it cannot be
parried.]
- When you plunder a countryside, let the spoil be divided amongst your men;
[Sun Tzu wishes to lessen the abuses of indiscriminate plundering by
insisting that all booty shall be thrown into a common stock, which may
afterwards be fairly divided amongst all.]
when you capture new territory, cut it up into allotments for the benefit
of the soldiery.
[Ch`en Hao says "quarter your soldiers on the land, and let them sow and
plant it." It is by acting on this principle, and harvesting the lands they
invaded, that the Chinese have succeeded in carrying out some of their most
memorable and triumphant expeditions, such as that of Pan Ch`ao who penetrated
to the Caspian, and in more recent years, those of Fu-k`ang-an and Tso
Tsung-t`ang.]
- Ponder and deliberate before you make a move.
[Chang Yu quotes Wei Liao Tzu as saying that we must not break camp until
we have gained the resisting power of the enemy and the cleverness of the
opposing general. Cf. the "seven comparisons" in I. ss. 13.]
- He will conquer who has learnt the artifice of deviation. [See supra, SS.
3, 4.]
Such is the art of maneuvering.
[With these words, the chapter would naturally come to an end. But there
now follows a long appendix in the shape of an extract from an earlier book on
War, now lost, but apparently extant at the time when Sun Tzu wrote. The style
of this fragment is not noticeable different from that of Sun Tzu himself,
but no commentator raises a doubt as to its genuineness.]
- The Book of Army Management says:
[It is perhaps significant that none of the earlier commentators give us
any information about this work. Mei Yao-Ch`en calls it "an ancient military
classic," and Wang Hsi, "an old book on war." Considering the enormous amount
of fighting that had g one on for centuries before Sun Tzu's time between the
various kingdoms and principalities of China, it is not in itself improbable
that a collection of military maxims should have been made and written down at
some earlier period.]
On the field of battle, [Implied, though not actually in the Chinese.] 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.
- Gongs and drums, banners and flags, are means whereby the ears and eyes of
the host may be focused on one particular point.
[Chang Yu says: "If sight and hearing converge simultaneously on the same
object, the evolutions of as many as a million soldiers will be like those of
a single man."!]
- 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.
[Chuang Yu quotes a saying: "Equally guilty are those who advance against
orders and those who retreat against orders." Tu Mu tells a story in this
connection of Wu Ch`i, when he was fighting against the Ch`in State. Before
the battle had begun, one of his soldiers, a man of matchless daring, sallied
forth by himself, captured two heads from the enemy, and returned to camp. Wu
Ch`i had the man instantly executed, whereupon an officer ventured to
remonstrate, saying: "This man was a good soldier, and ought not to have been
beheaded." Wu Ch`i replied: "I fully believe he was a good soldier, but I had
him beheaded because he acted without orders."]
This is the art of handling large masses of men.
- 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.
[Ch`en Hao alludes to Li Kuang-pi's night ride to Ho-yang at the head of
500 mounted men; they made such an imposing display with torches, that though
the rebel leader Shih Ssu-ming had a large army, he did not dare to dispute
their passage.]
- A whole army may be robbed of its spirit;
["In war," says Chang Yu, "if a spirit of anger can be made to pervade all
ranks of an army at one and the same time, its onset will be irresistible. Now
the spirit of the enemy's soldiers will be keenest when they have newly
arrived on the scene, and it is therefore our cue not to fight at once, but to
wait until their ardor and enthusiasm have worn off, and then strike. It is in
this way that they may be robbed of their keen spirit." Li Ch`uan and others
tell an anecdote (to be found in the TSO C HUAN, year 10, ss. 1) of Ts`ao
Kuei, a protege of Duke Chuang of Lu. The latter State was attacked by Ch`i,
and the duke was about to join battle at Ch`ang-cho, after the first roll of
the enemy's drums, when Ts`ao said: "Not just yet."]
[Only after their drums had beaten for the third time, did he give the word
for attack. Then they fought, and the men of Ch`i were utterly defeated.
Questioned afterwards by the Duke as to the meaning of his delay, Ts`ao Kuei
replied: "In battle, a courageous spirit is everything. Now the first roll of
the drum tends to create this spirit, but with the second it is already on the
wane, and after the third it is gone altogether. I attacked when their spirit
was gone and ours was at its height. Hence our victory." Wu Tzu (chap. 4)
puts "spirit" first among the "four important influences" in war, and
continues: "The value of a whole army--a mighty host of a million men--is
dependent on one man alone: such is the influence of spirit!"]
a commander-in-chief may be robbed of his presence of mind.
[Chang Yu says: "Presence of mind is the general's most important asset. It
is the quality which enables him to discipline disorder and to inspire courage
into the panic-stricken." The great general Li Ching (A.D. 571-649) has a
saying: "Attacking does not merely consist in assaulting walled cities or
striking at an army in battle array; it must include the art of assailing the
enemy's mental equilibrium."]
- Now a soldier's spirit is keenest in the morning;
[Always provided, I suppose, that he has had breakfast. At the battle of
the Trebia, the Romans were foolishly allowed to fight fasting, whereas
Hannibal's men had breakfasted at their leisure. See Livy, XXI, liv. 8, lv. 1
and 8.]
by noonday it has begun to flag; and in the evening, his mind is bent only
on returning to camp.
- 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.
- Disciplined and calm, to await the appearance of disorder and hubbub
amongst the enemy:--this is the art of retaining self-possession.
- 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.
- 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.
- It is a military axiom not to advance uphill against the enemy, nor to
oppose him when he comes downhill.
- Do not pursue an enemy who simulates flight; do not attack soldiers whose
temper is keen.
- Do not swallow bait offered by the enemy.
[Li Ch`uan and Tu Mu, with extraordinary inability to see a metaphor, take
these words quite literally of food and drink that have been poisoned by the
enemy. Ch`en Hao and Chang Yu carefully point out that the saying has a wider
application.]
Do not interfere with an army that is returning home.
[The commentators explain this rather singular piece of advice by saying
that a man whose heart is set on returning home will fight to the death
against any attempt to bar his way, and is therefore too dangerous an opponent
to be tackled. Chang Yu quote s the words of Han Hsin: "Invincible is the
soldier who hath his desire and returneth homewards." A marvelous tale is told
of Ts`ao Ts`ao's courage and resource in ch. 1 of the SAN KUO CHI: In 198
A.D., he was besieging Chang Hsiu in Jang, when Liu Pi ao sent reinforcements
with a view to cutting off Ts`ao's retreat. The latter was obliged to draw
off his troops, only to find himself hemmed in between two enemies, who were
guarding each outlet of a narrow pass in which he had engaged himself. In this desperate plight Ts`ao waited until nightfall, when he bored a tunnel into
the mountain side and laid an ambush in it. As soon as the whole army had
passed by, the hidden troops fell on his rear, while Ts`ao himself turned and
met his pursuers in front, so that they were thrown into confusion and
annihilated. Ts`ao Ts`ao said afterwards: "The brigands tried to check my army
in its retreat and brought me to battle in a desperate position: hence I knew
how to overcome them."]
- When you surround an army, leave an outlet free.
[This does not mean that the enemy is to be allowed to escape. The object,
as Tu Mu puts it, is "to make him believe that there is a road to safety, and
thus prevent his fighting with the courage of despair." Tu Mu adds pleasantly:
"After that, you ma y crush him."]
Do not press a desperate foe too hard.
[Ch`en Hao quotes the saying: "Birds and beasts when brought to bay will
use their claws and teeth." Chang Yu says: "If your adversary has burned his
boats and destroyed his cooking-pots, and is ready to stake all on the issue
of a battle, he must not be pushed to extremities." Ho Shih illustrates the
meaning by a story taken from the life of Yen-ch`ing. That general, together
with his colleague Tu Chung-wei was surrounded by a vastly superior army of
Khitans in the year 945 A.D. The country was bare and desert-like, and the
little Chinese force was soon in dire straits for want of water. The wells
they bored ran dry, and the men were reduced to squeezing lumps of mud and
sucking out the moisture. Their ranks thinned rapidly, until at last Fu Yen
-ch`ing exclaimed: "We are desperate men. Far better to die for our country
than to go with fettered hands into captivity!" A strong gale happened to be
blowing from the northeast and darkening the air with dense clouds of sandy
dust. To Chung-wei was for waiting until this had abated before deciding on a
final attack; but luckily another officer, Li Shou-cheng by name, was quicker
to see an opportunity, and said: "They are many and we are few, but in the
midst of this sandstorm our numbers will not be discernible; victory will go
to the strenuous fighter, and the wind will be our best ally." Accordingly, Fu
Yen-ch`ing made a sudden and wholly unexpected onslaught with his cavalry,
routed the barbarians and succeeded in breaking through to safety.]
- Such is the art of warfare.
