Chapter XII. THE ATTACK BY FIRE

[Rather more than half the chapter (§§ 1-13) is devoted to the subject

of fire, after which the author branches off into other topics.]

1. Sun Tzŭ said: There are five ways of attacking with fire. The first

is to burn soldiers in their camp;

[So Tu Mu. Li Ch’uan says: "Set fire to the camp, and kill the

soldiers" (when they try to escape from the flames). Pan Ch’ao, sent on

a diplomatic mission to the King of Shan-shan [see XI. § 51, note],

found himself placed in extreme peril by the unexpected arrival of an

envoy from the Hsiung-nu [the mortal enemies of the Chinese]. In

consultation with his officers, he exclaimed: "Never venture, never

win! [1] The only course open to us now is to make an assault by fire

on the barbarians under cover of night, when they will not be able to

discern our numbers. Profiting by their panic, we shall exterminate

them completely; this will cool the King’s courage and cover us with

glory, besides ensuring the success of our mission.’ The officers all

replied that it would be necessary to discuss the matter first with the

Intendant. Pan Ch’ao then fell into a passion: ‘It is today,’ he cried,

‘that our fortunes must be decided! The Intendant is only a humdrum

civilian, who on hearing of our project will certainly be afraid, and

everything will be brought to light. An inglorious death is no worthy

fate for valiant warriors.’ All then agreed to do as he wished.

Accordingly, as soon as night came on, he and his little band quickly

made their way to the barbarian camp. A strong gale was blowing at the

time. Pan Ch’ao ordered ten of the party to take drums and hide behind

the enemy’s barracks, it being arranged that when they saw flames shoot

up, they should begin drumming and yelling with all their might. The

rest of his men, armed with bows and crossbows, he posted in ambuscade

at the gate of the camp. He then set fire to the place from the

windward side, whereupon a deafening noise of drums and shouting arose

on the front and rear of the Hsiung-nu, who rushed out pell-mell in

frantic disorder. Pan Ch’ao slew three of them with his own hand, while

his companions cut off the heads of the envoy and thirty of his suite.

The remainder, more than a hundred in all, perished in the flames. On

the following day, Pan Ch’ao, divining his thoughts, said with uplifted

hand: ‘Although you did not go with us last night, I should not think,

Sir, of taking sole credit for our exploit.’ This satisfied Kuo Hsun,

and Pan Ch’ao, having sent for Kuang, King of Shan-shan, showed him the

head of the barbarian envoy. The whole kingdom was seized with fear and

trembling, which Pan Ch’ao took steps to allay by issuing a public

proclamation. Then, taking the king’s sons as hostage, he returned to

make his report to Tou Ku." _Hou Han Shu_, ch. 47, ff. 1, 2.] ]

the second is to burn stores;

[Tu Mu says: "Provisions, fuel and fodder." In order to subdue the

rebellious population of Kiangnan, Kao Keng recommended Wen Ti of the

Sui dynasty to make periodical raids and burn their stores of grain, a

policy which in the long run proved entirely successful.]

the third is to burn baggage-trains;

[An example given is the destruction of Yuan Shao’s wagons and

impedimenta by Ts’ao Ts’ao in 200 A.D.]

the fourth is to burn arsenals and magazines;

[Tu Mu says that the things contained in "arsenals" and "magazines" are

the same. He specifies weapons and other implements, bullion and

clothing. Cf. VII. § 11.]

the fifth is to hurl dropping fire amongst the enemy.

[Tu Yu says in the _T’ung Tien:_ "To drop fire into the enemy’s camp.

The method by which this may be done is to set the tips of arrows

alight by dipping them into a brazier, and then shoot them from

powerful crossbows into the enemy’s lines."]

2. In order to carry out an attack, we must have means available.

[T’sao Kung thinks that "traitors in the enemy’s camp" are referred to.

But Ch’en Hao is more likely to be right in saying: "We must have

favourable circumstances in general, not merely traitors to help us."

Chia Lin says: "We must avail ourselves of wind and dry weather."]

the material for raising fire should always be kept in readiness.

[Tu Mu suggests as material for making fire: "dry vegetable matter,

reeds, brushwood, straw, grease, oil, etc." Here we have the material

cause. Chang Yu says: "vessels for hoarding fire, stuff for lighting

fires."]

3. There is a proper season for making attacks with fire, and special

days for starting a conflagration.

4. The proper season is when the weather is very dry; the special days

are those when the moon is in the constellations of the Sieve, the

Wall, the Wing or the Cross-bar;

[These are, respectively, the 7th, 14th, 27th, and 28th of the

Twenty-eight Stellar Mansions, corresponding roughly to Sagittarius,

Pegasus, Crater and Corvus.]

for these four are all days of rising wind.

5. In attacking with fire, one should be prepared to meet five possible

developments:

6. (1) When fire breaks out inside the enemy’s camp, respond at once

with an attack from without.

7. (2) If there is an outbreak of fire, but the enemy’s soldiers remain

quiet, bide your time and do not attack.

[The prime object of attacking with fire is to throw the enemy into

confusion. If this effect is not produced, it means that the enemy is

ready to receive us. Hence the necessity for caution.]

8. (3) When the force of the flames has reached its height, follow it

up with an attack, if that is practicable; if not, stay where you are.

[Ts’ao Kung says: "If you see a possible way, advance; but if you find

the difficulties too great, retire."]

9. (4) If it is possible to make an assault with fire from without, do

not wait for it to break out within, but deliver your attack at a

favourable moment.

[Tu Mu says that the previous paragraphs had reference to the fire

breaking out (either accidentally, we may suppose, or by the agency of

incendiaries) inside the enemy’s camp. "But," he continues, "if the

enemy is settled in a waste place littered with quantities of grass, or

if he has pitched his camp in a position which can be burnt out, we

must carry our fire against him at any seasonable opportunity, and not

await on in hopes of an outbreak occurring within, for fear our

opponents should themselves burn up the surrounding vegetation, and

thus render our own attempts fruitless." The famous Li Ling once

baffled the leader of the Hsiung-nu in this way. The latter, taking

advantage of a favourable wind, tried to set fire to the Chinese

general’s camp, but found that every scrap of combustible vegetation in

the neighbourhood had already been burnt down. On the other hand,

Po-ts’ai, a general of the Yellow Turban rebels, was badly defeated in

184 A.D. through his neglect of this simple precaution. "At the head of

a large army he was besieging Ch’ang-she, which was held by Huang-fu

Sung. The garrison was very small, and a general feeling of nervousness

pervaded the ranks; so Huang-fu Sung called his officers together and

said: "In war, there are various indirect methods of attack, and

numbers do not count for everything. [The commentator here quotes Sun

Tzŭ, V. §§ 5, 6 and 10.] Now the rebels have pitched their camp in the

midst of thick grass which will easily burn when the wind blows. If we

set fire to it at night, they will be thrown into a panic, and we can

make a sortie and attack them on all sides at once, thus emulating the

achievement of T’ien Tan.’ [See p. 90.] That same evening, a strong

breeze sprang up; so Huang-fu Sung instructed his soldiers to bind

reeds together into torches and mount guard on the city walls, after

which he sent out a band of daring men, who stealthily made their way

through the lines and started the fire with loud shouts and yells.

Simultaneously, a glare of light shot up from the city walls, and

Huang-fu Sung, sounding his drums, led a rapid charge, which threw the

rebels into confusion and put them to headlong flight." [_Hou Han Shu_,

ch. 71.]

10. (5) When you start a fire, be to windward of it. Do not attack from

the leeward.

[Chang Yu, following Tu Yu, says: "When you make a fire, the enemy will

retreat away from it; if you oppose his retreat and attack him then, he

will fight desperately, which will not conduce to your success." A

rather more obvious explanation is given by Tu Mu: "If the wind is in

the east, begin burning to the east of the enemy, and follow up the

attack yourself from that side. If you start the fire on the east side,

and then attack from the west, you will suffer in the same way as your

enemy."]

11. A wind that rises in the daytime lasts long, but a night breeze

soon falls.

[Cf. Lao Tzŭ’s saying: "A violent wind does not last the space of a

morning." (_Tao Te Ching_, chap. 23.) Mei Yao-ch’en and Wang Hsi say:

"A day breeze dies down at nightfall, and a night breeze at daybreak.

This is what happens as a general rule." The phenomenon observed may be

correct enough, but how this sense is to be obtained is not apparent.]

12. In every army, the five developments connected with fire must be

known, the movements of the stars calculated, and a watch kept for the

proper days.

[Tu Mu says: "We must make calculations as to the paths of the stars,

and watch for the days on which wind will rise, before making our

attack with fire." Chang Yu seems to interpret the text differently:

"We must not only know how to assail our opponents with fire, but also

be on our guard against similar attacks from them."]

13. Hence those who use fire as an aid to the attack show intelligence;

those who use water as an aid to the attack gain an accession of

strength.

14. By means of water, an enemy may be intercepted, but not robbed of

all his belongings.

[Ts’ao Kung’s note is: "We can merely obstruct the enemy’s road or

divide his army, but not sweep away all his accumulated stores." Water

can do useful service, but it lacks the terrible destructive power of

fire. This is the reason, Chang Yu concludes, why the former is

dismissed in a couple of sentences, whereas the attack by fire is

discussed in detail. Wu Tzŭ (ch. 4) speaks thus of the two elements:

"If an army is encamped on low-lying marshy ground, from which the

water cannot run off, and where the rainfall is heavy, it may be

submerged by a flood. If an army is encamped in wild marsh lands

thickly overgrown with weeds and brambles, and visited by frequent

gales, it may be exterminated by fire."]

15. Unhappy is the fate of one who tries to win his battles and succeed

in his attacks without cultivating the spirit of enterprise; for the

result is waste of time and general stagnation.

[This is one of the most perplexing passages in Sun Tzŭ. Ts’ao Kung

says: "Rewards for good service should not be deferred a single day."

And Tu Mu: "If you do not take opportunity to advance and reward the

deserving, your subordinates will not carry out your commands, and

disaster will ensue." For several reasons, however, and in spite of the

formidable array of scholars on the other side, I prefer the

interpretation suggested by Mei Yao-ch’en alone, whose words I will

quote: "Those who want to make sure of succeeding in their battles and

assaults must seize the favourable moments when they come and not shrink

on occasion from heroic measures: that is to say, they must resort to

such means of attack of fire, water and the like. What they must not

do, and what will prove fatal, is to sit still and simply hold to the

advantages they have got."]

16. Hence the saying: The enlightened ruler lays his plans well ahead;

the good general cultivates his resources.

[Tu Mu quotes the following from the _San Lueh_, ch. 2: "The warlike

prince controls his soldiers by his authority, kits them together by

good faith, and by rewards makes them serviceable. If faith decays,

there will be disruption; if rewards are deficient, commands will not

be respected."]

17. Move not unless you see an advantage; use not your troops unless

there is something to be gained; fight not unless the position is

critical.

[Sun Tzŭ may at times appear to be over-cautious, but he never goes so

far in that direction as the remarkable passage in the _Tao Te Ching_,

ch. 69. "I dare not take the initiative, but prefer to act on the

defensive; I dare not advance an inch, but prefer to retreat a foot."]

18. No ruler should put troops into the field merely to gratify his own

spleen; no general should fight a battle simply out of pique.

19. If it is to your advantage, make a forward move; if not, stay where

you are.

[This is repeated from XI. § 17. Here I feel convinced that it is an

interpolation, for it is evident that § 20 ought to follow immediately

on § 18.]

20. Anger may in time change to gladness; vexation may be succeeded by

content.

21. But a kingdom that has once been destroyed can never come again

into being;

[The Wu State was destined to be a melancholy example of this saying.]

nor can the dead ever be brought back to life.

22. Hence the enlightened ruler is heedful, and the good general full

of caution. This is the way to keep a country at peace and an army

intact.
