The Art of War (孫子兵法), Weak Points And Strong 虛實篇

故我欲戰敵雖高壘深溝不得不與我戰者攻其所必救也

If we wish to fight, the enemy can be forced to an engagement even though he be sheltered behind a high rampart and a deep ditch. All we need do is to attack some other place that he will be obliged to relieve.

Lionel Giles's notes

Tu Mu says: “If the enemy is the invading party, we can cut his line of communications and occupy the roads by which he will have to return; if we are the invaders, we may direct our attack against the sovereign himself.” It is clear that Sun Tzŭ, unlike certain generals in the late Boer war, was no believer in frontal attacks.
