“The art of using troops is this: When ten to the enemy's one, surround him; When five times his strength, attack him (if my force is five times that of the enemy I alarm him to the front, surprise him to the rear, create an uproar in the east and strike in the west); If double his strength, divide him (if a two-to-one superiority is insufficient to manipulate the situation, we use a distracting force to divide his army); If equally matched you may engage him (in these circumstances only the able general can win); If weaker numerically, be capable of withdrawing (if I am in good order and the enemy in disarray, if I am energetic and he careless, then, even if he be numerically stronger, I can give battle); And if in all respects unequal, be capable of eluding him, for a small force is but booty for one more powerful (the small certainly cannot equal the large, nor can the weak match the strong, nor the few the many).”
