Mbh 12.103.4d

An intelligent king, even if competent for it, should not begin to crush all (his foes) at once.[313] When a king happens to have a large army consisting of sixfold forces[314] and teeming with horse, elephants, cars, foot, and engines, all devoted to him, when he thinks himself superior to his foe in many respects upon a fair comparison, then should he openly smite the foe without hesitation. If the foe be strong, the adoption of a policy of conciliation (towards him) is not worthy of approbation. On the other hand, chastisement by secret means is the policy that should be adopted. Nor should mildness of behaviour be adopted towards such foes, nor repeated expedition, for loss of crops, poisoning of wells and tanks, and suspicion in respect of the seven branches of administration, should be avoided.[315] The king should, on such occasions, apply diverse kinds of deception, diverse contrivances for setting his foes against one another, and different kinds of hypocritical behaviour. He should also, through trusted agents, ascertain the doings of his foes in their cities and provinces. Kings, O slayer of Vala and Vritra, pursuing their foes and entering their towers, seize and appropriate the best things that are obtainable there, and devise proper measures of policy in their own cities and dominions. Making gifts of wealth unto them in private, and confiscating their possessions publicly, without, however, injuring them materially, and proclaiming that they are all wicked men that have suffered for their own misdeeds, kings should send their agents to the cities and provinces of their foes. At the same time, in their own cities, they should, through other persons conversant with the scriptures, adorned with every accomplishment, acquainted with the ordinances of the sacred books and possessed of learning cause incantations and foe-killing rites to be performed.'
