3. Thus the good fighter is able to secure himself against defeat,
Chang Yü says: “By concealing the disposition of his troops, covering up his tracks, and taking unremitting precautions.”
but cannot make certain of defeating the enemy.
4. Hence the saying: One may
know
how to conquer without being able to
do
it.
5. Security against defeat implies defensive tactics; ability to defeat the enemy means taking the offensive.
The commentators are all against me. The meaning they give, “He who cannot conquer takes the defensive,” is plausible enough, but . . . highly improbable.
6. Standing on the defensive indicates insufficient strength; attacking, a superabundance of strength.
7. The general who is skilled in defence hides in the most secret recesses of the earth;
Literally, “hides under the ninth earth,” which is a metaphor indicating the utmost secrecy and concealment, so that the enemy may not know his whereabouts.
Batista has 3,000 men in the field against us. It is a battle against time, and time is on our side. They never know where we are, but we always know where they are.
Fidel Castro (February 24, 1957)
he who is skilled in attack flashes forth from the topmost heights of heaven.
Another metaphor, implying that he falls on his adversary like a thunderbolt, against which there is no time to prepare. This is the opinion of most of the commentators, though Ts’ao Kung, followed by Tu Yu, explains “secret recesses” as the hills, rivers, and other natural features which will afford shelter or protection to the attacked, and “topmost heights of heaven” as the phases of weather which may be turned to account by the attacking party.
Thus on the one hand we have ability to protect ourselves; on the other, a victory that is complete.
8. To see victory only when it is within the ken of the common herd is not the acme of excellence.
As Ts’ao Kung remarks, “The thing is to see the plant before it has germinated,” to foresee the event before the action has begun. Li Ch’üan alludes to the story of Han Hsin who, when about to attack the vastly superior army of Chao, which was strongly entrenched in the city of Ch’êng-an, said to his officers, “Gentlemen, we are going to annihilate the enemy, and shall meet again at dinner.” The officers hardly took his words seriously, and gave a very dubious assent. But Han Hsin had already worked out in his mind the details of a clever stratagem, whereby, as he foresaw, he was able to capture the city and inflict a crushing defeat on his adversary.
9. Neither is it the acme of excellence if you fight and conquer and the whole Empire says, “Well done!”
True excellence being, as Tu Mu says: “To plan secretly, to move surreptitiously, to foil the enemy’s intentions and baulk his schemes, so that at last the day may be won without shedding a drop of blood.” Sun Tzu reserves his approbation for things that
“the world’s coarse thumb
And finger fail to plumb.”
10. To lift an autumn hair is no sign of great strength; to see sun and moon is no sign of sharp sight; to hear the noise of thunder is no sign of a quick ear.
11. What the ancients called a clever fighter is one who not only wins, but excels in winning with ease.
Mei Yao-ch’ên says: “He who only sees the obvious, wins his battles with difficulty; he who looks below the surface of things, wins with ease.”
12. Hence his victories bring him neither reputation for wisdom nor credit for courage.
Tu Mu explains this very well, “Inasmuch as his victories are gained over circumstances that have not come to light, the world at large knows nothing of them, and he wins no reputation for wisdom; inasmuch as the hostile state submits before there has been any bloodshed, he receives no credit for courage.”
13. He wins his battles by making no mistakes.
Ch’ên Hao says: “He plans no superfluous marches, he devises no futile attacks.” The connection of ideas is thus explained by Chang Yü: “One who seeks to conquer by sheer strength, clever though he may be at winning pitched battles, is also liable on occasion to be vanquished; whereas he who can look into the future and discern conditions that are not yet manifest, will never make a blunder and therefore invariably win.”
