[Here again, Sun Tzŭ does not mean that the general is to be careless of the welfare of his troops. All he wishes to emphasize is the danger of sacrificing any important military advantage to the immediate comfort of his men. This is a shortsighted policy, because in the long run the troops will suffer more from the defeat, or, at best, the prolongation of the war, which will be the consequence. A mistaken feeling of pity will often induce a general to relieve a beleaguered city, or to reinforce a hard-pressed detachment, contrary to his military instincts. It is now generally admitted that our repeated efforts to relieve Ladysmith in the South African War were so many strategical blunders which defeated their own purpose. And in the end, relief came through the very man who started out with the distinct resolve no longer to subordinate the interests of the whole to sentiment in favour of a part. An old soldier of one of our generals who failed most conspicuously in this war, tried once, I remember, to defend him to me on the ground that he was always "so good to his men." By this plea, had he but known it, he was only condemning him out of Sun Tzŭ’s mouth.] 13. These are the five besetting sins of a general, ruinous to the conduct of war. 14. When an army is overthrown and its leader slain, the cause will surely be found among these five dangerous faults. Let them be a subject of meditation. [1] "Marshal Turenne," p. 50. Chapter IX. THE ARMY ON THE MARCH [The contents of this interesting chapter are better indicated in § 1 than by this heading.] 1. Sun Tzŭ said: We come now to the question of encamping the army, and observing signs of the enemy. Pass quickly over mountains, and keep in the neighbourhood of valleys. [The idea is, not to linger among barren uplands, but to keep close to supplies of water and grass. Cf. Wu Tzŭ, ch. 3: "Abide not in natural ovens," i.e. "the openings of valleys." Chang Yu tells the following anecdote: Wu-tu Ch’iang was a robber captain in the time of the Later Han, and Ma Yuan was sent to exterminate his gang. Ch’iang having found a refuge in the hills, Ma Yuan made no attempt to force a battle, but seized all the favourable positions commanding supplies of water and forage. Ch’iang was soon in such a desperate plight for want of provisions that he was forced to make a total surrender. He did not know the advantage of keeping in the neighbourhood of valleys."] 2. Camp in high places, [Not on high hills, but on knolls or hillocks elevated above the surrounding country.] facing the sun. [Tu Mu takes this to mean "facing south," and Ch’en Hao "facing east." Cf. infra, §§ 11, 13. Do not climb heights in order to fight. So much for mountain warfare. 3. After crossing a river, you should get far away from it.
