§ 124. According to a customary rule of the Law of Nations belligerents have the right to demand from one another that dead soldiers shall not be disgracefully treated, especially not mutilated, and shall be, so far as possible, collected and buried[252] or cremated on the battlefield by the victor. The Geneva Convention does not stipulate any rule concerning the collection and burial or cremation of the dead, but article 3 enacts that after each engagement the commander in possession of the field must take measures to ensure protection of the dead against pillage and maltreatment, and that a careful examination of the bodies, in order to see that life is really extinct, must be made before the dead are buried or cremated. Each belligerent must send as soon as possible to the authorities of the country or army to which they belong the military identification marks or tokens found on the dead (article 4). Pieces of equipment found upon the dead of the enemy are public enemy property and may, therefore, be appropriated as booty[253] by the victor. On the other hand, letters, money, jewellery, and such other articles of value found upon the dead on the battlefield, or on those who die in the medical units or fixed establishments, as are apparently private property, are not booty, but must, according to article 4 of the Geneva Convention and article 14 of the Hague rules concerning warfare on land, be collected and handed over to the Bureau of Information[254] concerning the prisoners of war, which has to transmit them to the persons interested through the channel of the authorities of their own country.
