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

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

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. On difficult ground, I would keep pushing on along the road.

50.                       On hemmed-in ground, I would block any way of retreat. On desperate ground, I would proclaim to my soldiers the hopelessness of saving their lives.

51.                       For it is the soldier's disposition to offer an obstinate resistance when surrounded, to fight hard when he cannot help himself, and to obey promptly when he has fallen into danger.

52.                       We cannot enter into alliance with neighboring princes until we are acquainted with their designs. 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 advantages to account unless we make use of local guides.

53.                       To be ignored of any one of the following four or five principles does not befit a warlike prince.

54.                       When a warlike prince attacks a powerful state, his generalship shows itself in preventing the concentration of the enemy's forces. He overawes his opponents, and their allies are prevented from joining against him.

55.                       Hence he does not strive to ally himself with all and sundry, nor does he foster the power of other states. He carries out his own secret designs, keeping his antagonists in awe. Thus he is able to capture their cities and overthrow their kingdoms.

56.                       Bestow rewards without regard to rule, issue orders without regard to previous arrangements; and you will be able to handle a whole army as though you had to do with but a single man.

57.                       Confront your soldiers with the deed itself; never let them know your design. When the outlook is bright, bring it before their eyes; but tell them nothing when the situation is gloomy.

58.                       Place your army in deadly peril, and it will survive; plunge it into desperate straits, and it will come off in safety.

59.                       For it is precisely when a force has fallen into harm's way that is capable of striking a blow for victory.

60.                       Success in warfare is gained by carefully accommodating ourselves to the enemy's purpose.

61.                       By persistently hanging on the enemy's flank, we shall succeed in the long run in killing the commander-in-chief.

62.                       This is called ability to accomplish a thing by sheer cunning.

63.                       On the day that you take up your command, block the frontier passes, destroy the official tallies, and stop the passage of all emissaries.

64.                       Be stern in the council-chamber, so that you may control the situation.

65.                       If the enemy leaves a door open, you must rush in.

66.                       Forestall your opponent by seizing what he holds dear, and subtly contrive to time his arrival on the ground.

67.                       Walk in the path defined by rule, and accommodate yourself to the enemy until you can fight a decisive battle.

68.                       At first, then, exhibit the coyness of a maiden, until the enemy gives you an opening; afterwards emulate the rapidity of a running hare, and it will be too late for the enemy to oppose you.
