under all circumstances to maintain them, and provide quarters, food, and clothing for them on the same footing as for its own troops. Officer prisoners must receive the same pay as officers of corresponding rank in the country where they are detained, the amount to be repaid by their Government after the conclusion of peace. All prisoners of war must enjoy every latitude in the exercise of their religion, including attendance at their own church service, provided only they comply with the regulations for order issued by the military authorities. If a prisoner wants to make a will, it must be received by the authorities or drawn up on the same conditions as for soldiers of the national army. And the same rules are valid regarding death certificates and the burial of prisoners of war, and due regard must be paid to their grade and rank. Letters, money orders, valuables, and postal parcels destined for or despatched by prisoners of war must enjoy free postage, and gifts and relief in kind for prisoners of war must be admitted free from all custom and other duties as well as payments for carriage by Government railways (article 16). [Footnote 258: See below, § 144.] [Footnote 259: See _Land Warfare_, § 69.] [Sidenote: Who may claim to be Prisoners of War.] § 127. Every individual who is deprived of his liberty not for a crime but for military reasons has a claim to be treated as a prisoner of war. Article 13 of the Hague Regulations expressly enacts that non-combatant[260] members of armed forces, such as newspaper correspondents, reporters, sutlers, contractors, who are captured and detained, may claim to be treated as prisoners of war, provided they can produce a certificate from the military authorities of the army they were accompanying. But although the Hague Regulations do not contain anything regarding the treatment of private enemy individuals and enemy officials whom a belligerent thinks it necessary[261] to make prisoners of war, it is evident that they may claim all privileges of such prisoners. Such individuals are not convicts; they are taken into captivity for military reasons, and they are therefore prisoners of war.
