text: FM 2-22.3 ____________________________________________________________________________________
  If the combat zone draws closer to a camp, the prisoners of war in the said camp shall not be
  transferred unless their transfer can be carried out in adequate conditions of safety, or if they
  are exposed to greater risks by remaining on the spot than by being transferred.
  ARTICLE 48
  In the event of transfer, prisoners of war shall be officially advised of their departure and of their
  new postal address. Such notifications shall be given in time for them to pack their luggage and
  inform their next of kin.
  They shall be allowed to take with them their personal effects, and the correspondence and
  parcels which have arrived for them. The weight of such baggage may be limited, if the
  conditions of transfer so require, to what each prisoner can reasonably carry, which shall in no
  case be more than twenty-five kilograms per head.
  Mail and parcels addressed to their former camp shall be forwarded to them without delay. The
  camp commander shall take, in agreement with the prisoners' representative, any measures
  needed to ensure the transport of the prisoners' community property and of the luggage they are
  unable to take with them in consequence of restrictions imposed by virtue of the second
  paragraph of this Article.
  The costs of transfers shall be borne by the Detaining Power.
  SECTION III LABOR OF PRISONERS OF WAR
  ARTICLE 49

  account their age, sex, rank and physical aptitude, and with a view particularly to maintaining
  them in a good state of physical and mental health.
  Non-commissioned officers who are prisoners of war shall only be required to do supervisory
  work. Those not so required may ask for other suitable work which shall, so far as possible, be
  found for them.
  If officers or persons of equivalent status ask for suitable work, it shall be found for them, so far
  as possible, but they may in no circumstances be compelled to work.

  Besides work connected with camp administration, installation or maintenance, prisoners of war
  may be compelled to do only such work as is included in the following classes:
  (a) Agriculture;
  (b) Industries connected with the production or the extraction of raw materials, and
  manufacturing industries, with the exception of metallurgical, machinery and chemical
  industries; public works and building operations which have no military character or purpose;
