Art. 57. So soon as a man is armed by a sovereign government and takes the soldier's oath of fidelity, he is a belligerent; his killing, wounding, or other warlike acts are not individual crimes or offenses. No belligerent has a right to declare that enemies of a certain class, color, or condition, when properly organized as soldiers, will not be treated by him as public enemies.
