Practice relating to Rule 66. Non-Hostile Contacts between the Parties to the Conflict
Section D. Refusal to receive parlementaires
Côte d’Ivoire’s Teaching Manual (2007) provides in Book III, Volume 1 (Instruction of first-year trainee officers):
II.4. The white flag (the flag of truce)
The white flag signifies “I want to enter into communication or negotiate with you”, and not necessarily “I want to surrender”. How does one use the white flag? The party which uses the white flag must cease firing. As soon as it has done so, the other side must do the same. Enemy forces then can in certain cases show their surrender in an evident manner, by throwing away their weapons and raising their arms. A surrender is generally accepted and the enemy is treated consequently, but there is no obligation to receive a delegation of parlementaires.
