Section B. Use of the white flag of truce
Belgium’s Law of War Manual (1983) expressly recognizes the white flag as the flag of parlementaires.
Belgium’s Teaching Manual for Soldiers recognizes “the white flag of parlementaires (used for negotiation or surrender)”.
The manual states: “This flag is actually recognized as the signal of a request for suspension of operations to enter into negotiations or to surrender.”
