Prisoners of war are subject to confinement or imprisonment such as may be deemed necessary on account of safety, but they are to be subjected to no other intentional suffering or indignity. The confinement and mode of treating a prisoner may be varied during his captivity according to the demands of safety.
76
Prisoners of war shall be fed upon plain and wholesome food, whenever practicable, and treated with humanity.
They may be required to work for the benefit of the captor's government, according to their rank and condition.
77
A prisoner of war who escapes may be shot or otherwise killed in his flight; but neither death nor any other punishment shall be inflicted upon him simply for his attempt to escape, which the law of war does not consider a crime. Stricter means of security shall be used after an unsuccessful attempt at escape.
If, however, a conspiracy is discovered, the purpose of which is a united or general escape, the conspirators may be rigorously punished, even with death; and capital punishment may also be inflicted upon prisoners of war discovered to have plotted rebellion against the authorities of the captors, whether in union with fellow prisoners or other persons.
78
If prisoners of war, having given no pledge nor made any promise on their honor, forcibly or otherwise escape, and are captured again in battle after having rejoined their own army, they shall not be punished for their escape, but shall be treated as simple prisoners of war, although they will be subjected to stricter confinement.
