[Tu Mu says: "The army is only cognizant of orders to advance or retreat; it is ignorant of the ulterior ends of attacking and conquering."]

40. To muster his host and bring it into danger:—this may be termed the business of the general.

[Sun Tzu means that after mobilization there should be no delay in aiming a blow at the enemy's heart. Note how he returns again and again to this point. Among the warring states of ancient China, desertion was no doubt a much more present fear and serious evil than it is in the armies of today.]

     41. The different measures suited to the nine varieties of
ground;

     [Chang Yu says: "One must not be hide-bound in interpreting
the rules for the nine varieties of ground.]

the expediency of aggressive or defensive tactics; and the fundamental laws of human nature: these are things that must most certainly be studied. 42. When invading hostile territory, the general principle is, that penetrating deeply brings cohesion; penetrating but a short way means dispersion.

[Cf. supra, ss. 20.]

43. When you leave your own country behind, and take your army across neighborhood territory, you find yourself on critical ground.

[This "ground" is curiously mentioned in VIII. ss. 2, but it does not figure among the Nine Situations or the Six Calamities in chap. X. One's first impulse would be to translate it distant ground," but this, if we can trust the commentators, is precisely what is not meant here. Mei Yao-ch`en says it is "a position not far enough advanced to be called 'facile,' and not near enough to home to be 'dispersive,' but something between the two." Wang Hsi says: "It is ground separated from home by an interjacent state, whose territory we have had to cross in order to reach it. Hence, it is incumbent on us to settle our business there quickly." He adds that this position is of rare occurrence, which is the reason why it is not included among the Nine Situations.]

When there are means of communication on all four sides, the ground is one of intersecting highways. 44. When you penetrate deeply into a country, it is serious ground. When you penetrate but a little way, it is facile ground. 45. When you have the enemy's strongholds on your rear, and narrow passes in front, it is hemmed-in ground. When there is no place of refuge at all, it is desperate ground. 46. Therefore, on dispersive ground, I would inspire my men with unity of purpose.

     [This end, according to Tu Mu, is best attained by remaining
on the defensive, and avoiding battle. Cf. supra, ss. 11.]

On facile ground, I would see that there is close connection between all parts of my army.

[As Tu Mu says, the object is to guard against two possible contingencies: "(1) the desertion of our own troops; (2) a sudden attack on the part of the enemy." Cf. VII. ss. 17. Mei Yao-ch`en says: "On the march, the regiments should be in close touch; in an encampment, there should be continuity between the fortifications."]

47. On contentious ground, I would hurry up my rear.

[This is Ts`ao Kung's interpretation. Chang Yu adopts it, saying: "We must quickly bring up our rear, so that head and tail may both reach the goal." That is, they must not be allowed to straggle up a long way apart. Mei Yao-ch`en offers another equally plausible explanation: "Supposing the enemy has not yet reached the coveted position, and we are behind him, we should advance with all speed in order to dispute its possession." Ch`en Hao, on the other hand, assuming that the enemy has had time to select his own ground, quotes VI. ss. 1, where Sun Tzu warns us against coming exhausted to the attack. His own idea of the situation is rather vaguely expressed: "If there is a favorable position lying in front of you, detach a picked body of troops to occupy it, then if the enemy, relying on their numbers, come up to make a fight for it, you may fall quickly on their rear with your main body, and victory will be assured." It was thus, he adds, that Chao She beat the army of Ch`in. (See p. 57.)]

48. On open ground, I would keep a vigilant eye on my defenses. On ground of intersecting highways, I would consolidate my alliances. 49. On serious ground, I would try to ensure a continuous stream of supplies.

[The commentators take this as referring to forage and plunder, not, as one might expect, to an unbroken communication with a home base.]

On difficult ground, I would keep pushing on along the road. 50. On hemmed-in ground, I would block any way of retreat.

[Meng Shih says: "To make it seem that I meant to defend the position, whereas my real intention is to burst suddenly through the enemy's lines." Mei Yao-ch`en says: "in order to make my soldiers fight with desperation." Wang Hsi says, "fearing lest my men be tempted to run away." Tu Mu points out that this is the converse of VII. ss. 36, where it is the enemy who is surrounded. In 532 A.D., Kao Huan, afterwards Emperor and canonized as Shen-wu, was surrounded by a great army under Erh- chu Chao and others. His own force was comparatively small, consisting only of 2000 horse and something under 30,000 foot. The lines of investment had not
