6. There is no instance of a country having benefited
from prolonged warfare.

7. It is only one who is thoroughly acquainted
with the evils of war that can thoroughly understand
the profitable way of carrying it on.

8. The skillful soldier does not raise a second levy,
neither are his supply-wagons loaded more than twice.

9. Bring war material with you from home, but forage
on the enemy. Thus the army will have food enough
for its needs.

10. Poverty of the State exchequer causes an army
to be maintained by contributions from a distance.
Contributing to maintain an army at a distance causes
the people to be impoverished.

11. On the other hand, the proximity of an army causes
prices to go up; and high prices cause the people's
substance to be drained away.

12. When their substance is drained away, the peasantry
will be afflicted by heavy exactions.

13,14. With this loss of substance and exhaustion
of strength, the homes of the people will be stripped bare,
and three-tenths of their income will be dissipated;
while government expenses for broken chariots, worn-out horses,
breast-plates and helmets, bows and arrows, spears and shields,
protective mantles, draught-oxen and heavy wagons,
will amount to four-tenths of its total revenue.

15. Hence a wise general makes a point of foraging
on the enemy. One cartload of the enemy's provisions
is equivalent to twenty of one's own, and likewise
a single picul of his provender is equivalent to twenty
from one's own store.

16. Now in order to kill the enemy, our men must
be roused to anger; that there may be advantage from
defeating the enemy, they must have their rewards.
