“The proper season is when the weather is very dry; the special days are those when the moon is in certain constellations; for these are days of rising wind.”

Attack with fire needs the right dry, windy conditions; timing with nature multiplies the effect.
Chapter 12 gets meteorological: the proper season is when the weather is very dry; the special days are those when the moon is in certain constellations — days of rising wind. Fire, it turns out, is not a weapon but an amplifier, and the chapter insists you schedule around the amplifier. The general’s skill includes patience of a very specific kind: waiting on conditions that make the same act ten times larger.
An activist investor prepares a campaign for a year — the thesis, the allies, the filings. The strike waits for the dry season anyway: the quarter when the target’s earnings miss, the CEO transition rumor hardens, and the passive funds’ voting policies are up for review. The identical campaign, launched a season earlier into calm air, would have scorched nothing. Wind first; fire second.
Waiting for conditions is not weather-worship as strategy — the activist built everything buildable during the wait, exactly as the fire chapter’s material-readiness verse requires. The error the verse targets is the reverse ordering: ignition first, conditions hoped for. Timing multiplies; it never substitutes for the prepared means.
