Practice relating to Rule 66. Non-Hostile Contacts between the Parties to the Conflict
Section B. Use of the white flag of truce
South Africa’s LOAC Manual (1996) provides: “A white flag designates a truce, a request to negotiate or an indication of surrender.”
South Africa’s LOAC Teaching Manual (2008) states:
Handling of War Victims
…
- When combatants surrender, they must clearly indicate this intention, eg by raising their arms and discarding their weapons. Remember, a white flag is NOT only a sign of surrender, but also a sign of a wish to negotiate.
