CHAPTER SUMMARY (2.01-2.19): Conserving Resources and Managing People
[2.01] Generally, the requirements of warfare are this way: One thousand four-horse chariots, one thousand leather chariots, one hundred thousand belted armor, transporting provisions one thousand kilometers, the distribution of internal and on-the-field spending, the efforts of having guests,* materials such as glue and lacquer, tributes in chariots and armor, will amount to expenses of a thousand gold pieces a day.
[2.02] Only then can one hundred thousand troops be raised.
[2.03] When doing battle, seek a quick victory. A long battle will blunt weapons and diminish ferocity.
[2.04] If troops lay siege to a walled city, their strength will be exhausted.
[2.05] If the army is involved in a long campaign, the nation's resources will not suffice.
[2.06] When weapons are blunted and ferocity diminished, strength exhausted and resources depleted, the neighboring rulers will take advantage of these complications.
[2.07] Then even the wisest of counsels would not be able to avert the consequences that must ensue.
[2.08] Therefore, I have heard of military campaigns that were clumsy but swift, but I have never seen military campaigns that were skilled but protracted. No nation has ever benefited from protracted warfare.*
[2.09] Therefore, if one is not fully cognizant of the dangers inherent in doing battle, one cannot fully know the benefits of doing battle.
