Arthashastra
पर दुर्गम् अवस्कन्द्य स्कन्ध आवारं वा पतित परान् मुख अभिपन्नम् उक्त केश शस्त्र भय विरूपेभ्यश् च अभयम् अयुध्यमानेभ्यश् च दद्युः ॥
Having captured the fort or having returned to the camp after its capture, he should give quarter to those of the enemy's army who, whether as lying prostrate in the field, or as standing with their back turned to the conqueror, or with their hair dishevelled, with their weapons thrown down or with their body disfigured and shivering under fear, surrender themselves.
english translation
