In default of such an understanding, and as a general principle, prisoners of war shall be treated, as regards food and clothing, on the same footing as the troops of the Government who made them prisoners.
Art. 28. Prisoners of war are subject to the laws and regulations in force in the army in whose power they are.
Arms may be used, after summoning, against a prisoner attempting to escape. If retaken, he is subject to summary punishment or to a stricter surveillance.
If after having escaped he is again made prisoner, he is not liable to any punishment for his previous escape.
Art. 29. Every prisoner is bound to declare, if interrogated on the point, his true names and rank; and in the case of his infringing this rule, he will incur a restriction of the advantages granted to the prisoners of the class to which he belongs.
Art. 30. The exchange of prisoners of war is regulated by mutual agreement between the belligerents.
Art. 31. Prisoners of war may be released on parole if the laws of their country allow of it; and in such a case they are bound on their personal honor to fulfill scrupulously, as regards their own Government, as well as that which made them prisoners, the engagements they have undertaken.
In the same case their own Government should neither demand nor accept from them any service contrary to their parole.
Art. 32. A prisoner of war cannot be forced to accept release on parole, nor is the enemy's Government obliged to comply with the request of a prisoner claiming to be released on parole.
Art. 33. Every prisoner of war liberated on parole, and retaken carrying arms against the Government to which he had pledged his honor, may be deprived of the rights accorded to prisoners of war, and may be brought before the tribunals.
