“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.” Sun Tzu
