Practice relating to Rule 66. Non-Hostile Contacts between the Parties to the Conflict
Madagascar’s Military Manual (1994) mentions non-belligerent contacts with the enemy through intermediaries such as protecting powers or the ICRC.
It also states:
Local cease-fires and other agreements may be concluded between the opposing forces. At inferior levels, such agreements may be very simple and concluded orally: voice, radio or bearer of a white flag (flag of parlementaires). At superior levels and for long term cease-fires, written agreements are to be concluded.
Madagascar’s Military Manual (1994) states that the white flag is a means of contacting the enemy.
