imply maintain our ground, whole days and months will
crawl by; the moment we make a move, we have to sustain the
enemy's attacks on front and rear. The country is wild,
destitute of water and plants; the army is lacking in the
necessaries of life, the horses are jaded and the men worn-out,
all the resources of strength and skill unavailing, the pass so
narrow that a single man defending it can check the onset of ten
thousand; all means of offense in the hands of the enemy, all
points of vantage already forfeited by ourselves:--in this
terrible plight, even though we had the most valiant soldiers and
the keenest of weapons, how could they be employed with the
slightest effect?" Students of Greek history may be reminded of
the awful close to the Sicilian expedition, and the agony of the
Athenians under Nicias and Demonsthenes. [See Thucydides, VII.
78 sqq.].]

11. On dispersive ground, therefore, fight not. On facile
ground, halt not. On contentious ground, attack not.

[But rather let all your energies be bent on occupying the
advantageous position first. So Ts`ao Kung. Li Ch`uan and
others, however, suppose the meaning to be that the enemy has
already forestalled us, sot that it would be sheer madness to
attack. In the SUN TZU HSU LU, when the King of Wu inquires what
should be done in this case, Sun Tzu replies: "The rule with
regard to contentious ground is that those in possession have the
advantage over the other side. If a position of this kind is
secured first by the enemy, beware of attacking him. Lure him
away by pretending to flee--show your banners and sound your
drums--make a dash for other places that he cannot afford to
lose--trail brushwood and raise a dust--confound his ears and
eyes--detach a body of your best troops, and place it secretly in
ambuscade. Then your opponent will sally forth to the rescue."]

12. On open ground, do not try to block the enemy's way.

[Because the attempt would be futile, and would expose the
blocking force itself to serious risks. There are two
interpretations available here. I follow that of Chang Yu. The
other is indicated in Ts`ao Kung's brief note: "Draw closer
together"--i.e., see that a portion of your own army is not cut
off.]

On the ground of intersecting highways, join hands with your
allies.

[Or perhaps, "form alliances with neighboring states."]

13. On serious ground, gather in plunder.
