  SECTION III DEATH OF PRISONERS OF WAR
  ARTICLE 120
  Wills of prisoners of war shall be drawn up so as to satisfy the conditions of validity required by
  the legislation of their country of origin, which will take steps to inform the Detaining Power of
  its requirements in this respect. At the request of the prisoner of war and, in all cases, after
  death, the will shall be transmitted without delay to the Protecting Power; a certified copy shall
  be sent to the Central Agency.
  Death certificates in the form annexed to the present Convention, or lists certified by a
  responsible officer, of all persons who die as prisoners of war shall be forwarded as rapidly as
  possible to the Prisoner of War Information Bureau established in accordance with Article 122.
  The death certificates or certified lists shall show particulars of identity as set out in the third
  paragraph of Article 17, and also the date and place of death, the cause of death, the date and
  place of burial and all particulars necessary to identify the graves.
  The burial or cremation of a prisoner of war shall be preceded by a medical examination of the
  body with a view to confirming death and enabling a report to be made and, where necessary,
  establishing identity.
  The detaining authorities shall ensure that prisoners of war who have died in captivity are
  honorably buried, if possible according to the rites of the religion to which they belonged, and
  that their graves are respected, suitably maintained and marked so as to be found at any time.
  Wherever possible, deceased prisoners of war who depended on the same Power shall be interred
  in the same place.
  Deceased prisoners of war shall be buried in individual graves unless unavoidable circumstances
  require the use of collective graves. Bodies may be cremated only for imperative reasons of
  hygiene, on account of the religion of the deceased or in accordance with his express wish to this
  effect. In case of cremation, the fact shall be stated and the reasons given in the death certificate
  of the deceased.
  In order that graves may always be found, all particulars of burials and graves shall be recorded
  with a Graves Registration Service established by the Detaining Power. Lists of graves and
  particulars of the prisoners of war interred in cemeteries and elsewhere shall be transmitted to
  the Power on which such prisoners of war depended. Responsibility for the care of these graves
  and for records of any subsequent moves of the bodies shall rest on the Power controlling the
  territory, if a Party to the present Convention. These provisions shall also apply to the ashes,
  which shall be kept by the Graves Registration Service until proper disposal thereof in
  accordance with the wishes of the home country.
  ARTICLE 121
  Every death or serious injury of a prisoner of war caused or suspected to have been caused by a
  sentry, another prisoner of war, or any other person, as well as any death the cause of which is
  unknown, shall be immediately followed by an official enquiry by the Detaining Power.
