Kautilya's Arthashastra 13.4.2

13.4.2

janapadaṃ yathāniviṣṭam abhaye sthāpayet //

REDUCTION (of the enemy) must precede a siege. The territory that has been conquered should be kept so peacefully that it might sleep without any fear. When it is in rebellion, it is to be pacified by bestowing re- wards and remitting taxes, unless the conqueror means to quit it. Or he may select his battle fields in a remote part of the enemy's territory, far from the populous centres; for, in the opinion of Kautilya, no territory deserves the name of a kingdom or country unless it is full of people. When a people resist the attempt of the conqueror, then he may destroy their stores, crops, and granaries, and trade.
