地形第十

Terrain

Only about a third of the chapter, comprising ss. ss. 1-13, deals with "terrain," the subject being more fully treated in ch. XI. The "six calamities" are discussed in SS. 14-20, and the rest of the chapter is again a mere string of desultory remarks, though not less interesting, perhaps, on that account.

Sunzi X. 5.


	若敵先居之盈而勿從不盈而從之	隘形者我先居之必盈之以待敵

With regard to NARROW PASSES, if you can occupy them first, let them be strongly garrisoned and await the advent of the enemy.1

Should the army forestall you in occupying a pass, do not go after him if the pass is fully garrisoned, but only if it is weakly garrisoned.

1. Because then, as Tu Yu observes, "the initiative will lie with us, and by making sudden and unexpected attacks we shall have the enemy at our mercy."

Giles X.8,9.

Il y a des lieux qui n'offrent que d'étroits passages, qui sont bordés de rochers ou de précipices, qui n'ont pas d'accès facile avec les espaces libres desquels vous pouvez attendre du secours. Si vous êtes le premier à occuper ce terrain, bloquez les passages et attendez l'ennemi ; si l'ennemi est sur place avant vous, ne l'y suivez pas, à moins qu'il n'ait pas fermé complètement les défilés. Ayez-en une connaissance exacte pour ne pas y engager votre armée mal à propos.
