Shape your plans according to rule, and the circumstances of the enemy.
At first behave with the discretion of a maiden; then, when the enemy gives an opening, dart in like a rabbit.
The enemy cannot defend himself.

ASSAULT BY FIRE
Sun the Master said:—
There are five ways of attack by fire:
The first is called barrack burning; the second, commissariat burning; the third, equipment burning; the fourth, store burning; the fifth, the company burning.
The moment for the fire assault must be suitable. Further, appliances must always be kept at hand.
There is a time and day proper for the setting and carrying out of the fire assault; namely: such time as the weather is dry; and a day when the moon is in the quarters of the stars Chi, Pi, I, Chen: for these are days of wind.
