The art of using troops is this: ……When ten to the enemy’s one, surround him; ……When five times his strength, attack him; ……If double his strength, divide him; ……If equally matched you may engage him; ……If weaker numerically, be capable of withdrawing; ……And if in all respects unequal, be capable of eluding him, ……….for a small force is but booty for one more powerful.
