There was a problem when proofreading this page.


  1. 火發而其兵靜者待而勿攻
  2. 極其火力可從而從之不可從而止
  3. 火可發於外無待於內以時發之

7. (2) If there is an outbreak of fire, but the enemy's soldiers remain quiet, bide your time and do not attack.

The original text omits 而其. The prime object of attacking with fire is to throw the enemy into confusion. If this effect is not produced, it means that the enemy is ready to receive us. Hence the necessity for caution.

The latter, taking advantage of a favourable wind, tried to set fire to the Chinese general’s camp, but found that every scrap of combustible vegetation in the neighbourhood had already been burnt down. On the other hand, 波才 Po-ts‘ai, a general of the 黃巾賊 Yellow Turban rebels, was badly defeated in 184 A.D. through his neglect of this simple precaution. “At the head of a large army he was besieging 長社 Ch‘ang-shê, which was held by 皇甫嵩 Huang-fu Sung. The garrison was very
