The Art of War (孫子兵法), The Nine Situations 九地篇

聚三軍之衆投之於險此謂將軍之事也

To muster his host and bring it into danger: — this may be termed the business of the general.

Lionel Giles's notes

Sun Tzŭ means that after mobilisation there should be no delay in aiming a blow at the enemy’s heart. With 投之於險 cf. supra, § 23: 投之無所往. Note how he returns again and again to this point. Among the warring states of ancient China, desertion was no doubt a much more present fear and serious evil than it is in the armies of to-day.
