Chapter III: On Flags of Truce

ARTICLE XXXII.
An individual is considered as bearing a flag of truce who is
authorized by one of the belligerents to enter into
communication with the other, and who carries a white flag. He
has a right to inviolability, as well as the trumpeter,
bugler, or drummer, the flag-bearer, and the interpreter who
may accompany him.

ARTICLE XXXIII.
The Chief to whom a flag of truce is sent is not obliged to
receive it in all circumstances. He can take all steps
necessary to prevent the envoy taking advantage of his mission
to obtain information. In case of abuse, he has the right to
detain the envoy temporarily.

ARTICLE XXXIV.
The envoy loses his rights of inviolability if it is proved
beyond doubt that he has taken advantage of his privileged
position to provoke or commit an act of treachery.
