The Detaining Power shall also send through the Protecting Power to the government upon which the prisoner of war depends, lists giving all appropriate particulars of all prisoners of war whose captivity has been terminated by repatriation, release, escape, death or any other means, and showing the amount of their credit balances. Such lists shall be certified on each sheet by an authorized representative of the Detaining Power. Any of the above provisions of this Article may be varied by mutual agreement between any two Parties to the conflict. The Power on which the prisoner of war depends shall be responsible for settling with him any credit balance due to him from the Detaining Power on the termination of his captivity.
