Furthermore, they must give him complete religious liberty, and it is specifically decreed that he must be given opportunity to attend a church of the denomination to which he belongs. And there he may pray as much for the success of his own nation or the much-desired relief from detention as the state of his mind dictates. PRISONERS MAY BE CONFINED The prisoner of war may be interned in a town or a fort, or even a camp, according to the convenience of his captors, but the enemy may not confine him, except, the law says, as "an indispensable measure of safety," and then only as long as the circumstances make it necessary. Of course the law gives the commanding officer considerable leeway in such matters, for he is left to determine when the "indispensable" occasion arises. At other times when the prisoner is at liberty, he is subject to all the rules and regulations of the army of the government that captured him, and if he refuses to obey the rules or acts in an insubordinate manner toward the officers in command, he may be punished and disciplined according to his offense. And here it is again left to the discretion of his captors as to what measure of punishment shall be inflicted upon him. ATTEMPTS AT ESCAPE If a prisoner of war attempts to escape and his captors are vigilant to the extent of retaking him before he leaves the territory they occupy, or before he has a chance to rejoin his own army, he may be severely punished. On the other hand, if he eludes his captors and makes a clean getaway and his army is again unfortunate, and he is captured the second time, the perfectly good escape from previous captivity must go unpunished and he must be treated as a prisoner of war, just as though he had not made the successful dash for liberty and further glory. The government that holds prisoners of war is chargeable with their maintenance and must provide them with food, clothing and shelter as good as that provided for its own troops. The officers of the captors are required to keep records of all the prisoners under their charge, and if relief societies, which have been extensively formed by the women of Europe and many American women as well, wish to minister to their needs and comforts, the officers in command must afford them every possible facility. And if the friends of prisoners or the welfare societies see fit to send them presents and clothing, medicine and other necessities, such goods must be admitted to them free of any war duty that might be imposed by the nation holding them, and the railroads owned by the government are bound to carry such supplies free of transportation charges. CAPTIVES MUST BE PAID FOR WORK
