ARTICLE 18U.K.
The military authorities may appeal to the charity of the inhabitants voluntarily to collect and care for, under their direction, the wounded and sick, granting persons who have responded to this appeal the necessary protection and facilities. Should the adverse party take or retake control of the area, he shall likewise grant these persons the same protection and the same facilities.
The military authorities shall permit the inhabitants and relief societies, even in invaded or occupied areas, spontaneously to collect and care for wounded or sick of whatever nationality. The civilian population shall respect these wounded and sick, and in particular abstain from offering them violence.
No one may ever be molested or convicted for having nursed the wounded or sick.
The provisions of the present Article do not relieve the occupying Power of its obligations to give both physical and moral care to the wounded and sick.
