Arthashastra
तेषाम् अन्यतमम् उत्तिष्ठमानं संधिना मन्त्र युद्धेन कूट युद्धेन वा प्रतिव्यूहेत ॥
When any one of these is on the point of rising against a weak king, the latter should avert the invasion by making a treaty of peace, or by taking recourse to the battle of intrigue (mantrayuddha), or by a treacherous fight in the battle-field.
english translation
