Chapter 12
The Attack by Fire
THE ATTACK BY FIRE [Rather more than half the chapter (§§ 1-13) is devoted to the subject of fire, after which the author branches off into other topics.] 1. Sun Tzŭ said: There are five ways of attacking with fire. The first is to burn soldiers in their camp; [So Tu Mu. Li Ch’uan says: "Set fire to the camp, and kill the soldiers" (when they try to escape from the flames). Pan Ch’ao, sent on a diplomatic mission to the King of Shan-shan [see XI. § 51, note], found himself placed in extreme peril by the unexpected arrival of…

Key Quotes & Analysis
"There are five ways of attacking with fire. The first is to burn soldiers in their camp;"
Context: Opening taxonomy of fire targets
Leverage begins with choosing the right object to ignite, not with brute force.
In Today's Words:
Your force multiplier is not random chaos. Name the asset you could disrupt: the team before launch, the inventory line, the logistics chain, the budget reserve, or morale in the open. Each target needs different setup, but any can collapse resistance faster than a frontal fight if you prepare before you strike.
"When fire breaks out inside the enemy’s camp, respond at once with an attack from without."
Context: First of five fire developments
When disruption lands inside, speed from outside converts confusion into defeat.
In Today's Words:
When disruption hits inside their operation, move immediately from outside while they react. A server outage during their demo, a resignation during their funding round, or a compliance finding during a sales push creates the same window. Hesitation lets them regroup; a timed follow through while attention is split turns panic into your advantage.
"When you start a fire, be to windward of it. Do not attack from the leeward."
Context: Wind direction rule for fire attacks
Even powerful tools backfire if you stand on the wrong side of the force you unleash.
In Today's Words:
Position yourself so the force you unleash pushes toward them, not back into your face. Launch a price war only when your margins outlast theirs, publish criticism only when your record can absorb counterattack, or deploy automation only when your team owns the workflow. The wrong side turns your weapon into self inflicted damage.
"Move not unless you see an advantage; use not your troops unless there is something to be gained; fight not unless the position is critical."
Context: Closing restraint against pointless action
Activity without advantage is waste; permanent stakes deserve cold calculation, not reflex.
In Today's Words:
Do not spend reputation, budget, or team energy unless the expected gain clears a clear bar. Skip the retaliatory email, the vanity project, and the meeting fight that feels urgent but changes nothing. Reserve full commitment for moments when the position truly matters, because unnecessary battles tax the people you need when crisis arrives.

The Leverage Hunt
Identify potential leverage points in your current work—small actions that could produce disproportionate results.
Consider:
- •What single relationship could unlock multiple opportunities?

Sun Tzu closes with spies: foreknowledge cannot come from spirits or guesswork, only from people who know the enemy's situation. Intelligence is the foundation of everything else.
