The Military Manual (2005) of the Netherlands states:
The white flag indicates that the party flying the flag wishes to parley. This party must cease firing. The bearer of the white flag, and those accompanying this person, have a right to physical inviolability. The receiving party need not cease fire over the whole sector. The white flag is also accepted as the customary indication of a wish to surrender.
