Third Geneva Convention

The Geneva Convention relative to the Treatment of Prisoners of War was first adopted in 1929, but significantly revised at the 1949 conference.

Articles 13 to 16 state that prisoners of war must be treated humanely without any adverse discrimination and that their medical needs must be met.

It dictates what information a prisoner must give ("surname, first names and rank, date of birth, and army, regimental, personal or serial number"), and interrogation methods that the detaining power may use ("No physical or mental torture, nor any other form of coercion").

It goes into details about such things as the accommodation, medical facilities, and that even if the prisoner of war works for a private person the military authority remains responsible for them.

This covers the frequency of which a prisoner of war can send and receive post, including parcels.
