Section II : Duties and rights of belligerents - Art. 8.
Art. 8. A ship of war may not depart from a neutral port within less than twenty-four hours after the departure of an enemy warship. The one entering first shall depart first, unless it is in such condition as to warrant extending its stay. In any case the ship which arrived later has the right to notify the other through the competent local authority that within twenty-four hours it will leave the port, the one first entering, however, having the right to depart within that time. If it leaves, the notifying ship must observe the interval which is above stipulated.
