possible developments:

6. (1) When fire breaks out inside the enemy's camp, respond at

once with an attack from without.

7. (2) If there is an outbreak of fire, but the enemy's soldiers

remain quiet, bide your time and do not attack.

[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.]

8. (3) When the force of the flames has reached its height,

follow it up with an attack, if that is practicable; if not, stay

where you are.

[Ts'ao Kung says: "If you see a possible way, advance; but if you

find the difficulties too great, retire."]

9. (4) If it is possible to make an assault with fire from

without, do not wait for it to break out within, but deliver your

attack at a favourable moment.
