Sun Tzu
INTRODUCTION
IWritten in the fifth century B.C., Suntzu and Wutzu still
remain the most celebrated works on war in the literature of China.
While the chariot has gone, and weapons have changed, these ancient
masters have held their own, since they deal chiefly with the
fundamental principles of war, with the influence of politics and
human nature on military operations; and they show in a most
striking way how unchanging these principles are.When these books were written, China was a conglomerate of
principalities in continual ferment. Personal ambition and
intrigue, and not the wishes of the people, were the main factors
in these wars. Patriotism, or a popular cause, could not,
therefore, be relied on to maintain themoralof the levies. Instead of these,
what may be called the force of despair is pointed out as the most
powerful agent in giving cohesion and energy to an army. The
general is urged to take a vigorous offensive; and to act at a
distance from his base, where defeat means disaster, and where
desertion is minimised owing to the distance from home. He should,
in fact, burn his boats before an action, or, in Chinese phrase,
act as one who removes the ladder from under those mounted upon the
roof.On the other hand, every care must be taken not to render the
enemy desperate; and, as an instance of this, Sun observes that an
opponent should on no account be completely surrounded. A loop-hole
of escape weakens the resolution of the general and the energy of
his troops.It is interesting to notice thatmoral, or the spirit of the troops, is
thus considered a determining factor in war. The Chinese are
perhaps unusually affected by climatic conditions. As is well
known, the umbrella was part of a soldier’s equipment; and for the
same reasons, the sunny side of high ground is recommended as most
suitable for defence, tactical considerations
permitting.The large number of bannermen in the Chinese army was out of
all proportion to the service of standards in providing rallying
points. The chief use of banners was to maintain the spirit of the
troops. A forest of banners, held erect, gave a feeling of
liveliness and security to the ranks, in the same way as a military
band, and when Sun remarks that the march of an army should be calm
like the forest, he is using a simile that is not
inappropriate.Probably owing to the fact that the profession of arms has
never been highly regarded in China, we find that the ruler of the
state did not usually take the field, but employed a professional
to command the army—one of the masters of war who wandered from
state to state at that time with the secrets of victory to impart
to the highest bidder. The question of political interference with
the general in the field naturally arises under these conditions.
The two sages point out, that to unite the nation under firm and
just government is the business of the ruler and necessary to
victory; but that the general is the best judge of the questions
that arise on a distant field, and that all interference with him
causes delay and disaster.War meaning ravage, it was essential that the operations
should be conducted in the enemy’s territory. Once there, however,
a vigorous offensive is no longer advised. “At first behave with
the discretion of a maiden” is the counsel of Sun. The enemy must
be induced to take the initiative, and when he is worn out by
marching, or makes a false move, “then,” says the master, “dart in
like a rabbit.”Unlike the tactics of the Japanese, in whom the spirit of
attack burns so strongly, those of Suntzu and Wutzu are essentially
of the offensive-defensive order—manœuvre before fighting, and
non-committal until the enemy has shown his hand. The business of
the general is to avoid encounter in battle until the enemy is no
longer capable of offering a successful resistance.The masters do not make, however, the mistake of advocating a
passive defensive. Suntzu lays down that the division of the forces
which this strategy involves, is to be everywhere weak, rendering
the army liable to be taken in detail by the concentrated forces of
the enemy. It is rather the defence which avoids battle by mobility
and manœuvre, induces the enemy by stratagem to divide his forces,
or act in conformity with our wishes, and then falls upon
him.With regard to the tactics of the battlefield, the pitched
battle, or, in other words, the frontal attack, is considered
unworthy of the skilful general. The plan of attack should consist,
broadly speaking, in the division of the army into two forces. The
enemy is “attracted and engaged by one force, and defeated with the
other;” and here we have the containing or secondary attack, and
the main or reserve force which decides the battle of to-day—a most
striking instance of the continuity of military
principles.Considerable space is devoted to the influence of ground on
war. The passage of defiles and rivers is still conducted in the
same way. The many large rivers of China naturally affected
military operations; and, among other axioms, it is laid down that
the passage of a river should not be disputed, as the enemy will
probably give up the attempt, and make the passage untouched at
some other point, but that he should be attacked when half his
force is across the stream. Again, an army should not encamp on a
river below the enemy, as it is thereby liable to be inundated, or
to have its water poisoned; or the enemy may come down stream and
make a sudden attack.While both writers were professional soldiers, they show a
fine disinterestedness by repeatedly pointing out that even
successful war brings evil in its train. Wu remarks that “few are
those who have gained power on earth by many victories,” and he is
insistent that war should not be undertaken until a careful
comparison of the two sides shows that victory is certain; and he
adds, “The army which conquers makes certain of victory and then
attacks, while the army that is defeated fights in the hope of
success.”Hence the importance they assign to intelligence of the
enemy, and to the spy; and as the sages dealt with war between
members of the same race, the work of spies was greatly
facilitated. The spy was treated with great honour by his
countrymen, and the fact that many of the national heroes of China
were spies, shows that the part that they played was not forgotten.
They frequently toiled for years, and rose to high rank in the
enemy’s service; and thus, by wrong counsel and by spreading
mistrust in his ranks, they became a two-edged sword in the hands
of the general. “Wonderful, indeed, is their power,” exclaims Sun;
but he also reminds us that their management is the most difficult
and delicate duty of the general.IISun and Wu are perhaps held in even greater reverence in
Japan than in China, where war is looked upon as a troublesome
phase in national life, and victory in battle is not considered the
greatest achievement of a state. Far otherwise is it in Japan; and
successive generations of her soldiers have been brought up on Sun
and Wu. Like other arts, mystery was formerly supposed to surround
the art of war, a belief that was encouraged by the strategist; and
for a considerable time, the few copies of this book, that were
brought over from China to Japan, were jealously guarded by their
possessors. Later, as they became known, an army of Japanese
commentators arose—for Chinese literature is thought compressed, to
be unfolded in the mind of the reader.To-day Sun and Wu have given way to the scientific works of
European writers, but their sayings have become proverbs, and their
influence undoubtedly helped the Japanese to victory in the late
war. Belief in the importance of a knowledge of the enemy and his
resources, of preparation and training, had grown out of a long
study of these ancient masters; and since it was the vital
importance of a successful issue to the Japanese which, after all,
fired their resolution and carried them through, they proved the
sage’s words that it is the energy, born of despair, that wins the
victory.IIILittle is known of the life of either master. They were in no
sense patriots but professional strategists, continually changing
their employer. Chinese history tells a famous story about Sun. A
certain ruler asked Sun to give a practical demonstration of his
principles in the neighbourhood of the palace, and entrusted him
with the women of the court for this purpose. During the
operations, the leader of one of the sides did not obey the
master’s instructions, and her execution was ordered. She happened
to be the king’s favourite wife, but Sun pointed out that the
king’s wish that her life should be spared was a case of political
interference with the general in the field; and the sentence was
carried out.Wu is represented as a person of low moral character. On two
separate occasions, for fear of giving rise to suspicion, he killed
one of his wives who belonged to a state with which his employer at
the time was at war; and, graver still in the eyes of the Chinese
historian, he was not present at the death-bed of his
mother.E. F. C.NOTE.The translator is indebted to Major J. C. Somerville for his
