Part II : Application of general principles #III. Prisoners of war #A. Rules for captivity - Art. 68.
Art. 68. Arms may be used, after summoning, against a prisoner attempting to escape.
If he is recaptured before being able to rejoin his own army or to quit the territory of his captor, he is only liable to disciplinary punishment, or subject to a stricter surveillance.
But if, after succeeding in escaping, he is again captured, he is not liable to punishment for his previous flight.
If, however, the fugitive so recaptured or retaken has given his parole not to escape, he may be deprived of the rights of a prisoner of war.
