Practice Relating to Rule 46. Orders or Threats That No Quarter Will Be Given
Côte d’Ivoire’s Teaching Manual (2007) provides in Book IV (Instruction of heads of division and company commanders):
Chapter 3. Protection
I.2.4. Enemy hors de combat
It is prohibited to order that there shall be no survivors, to threaten an adversary therewith or to conduct hostilities on this basis. Consequently, a person who clearly expresses an intention to surrender, in whatever way, must not be made the object of attack.
Chapter 4. Methods and means of warfare
I.2.4. “Denial/no quarter”
It is prohibited not to give quarter. In other words, it is not lawful to order or to make understood that one will take no prisoners, to threaten an adversary with such an order, or to conduct hostilities on the basis of the principle that no prisoners will be taken.
