Art. 9. Belligerents may appeal to the charity of the commanders of neutral merchant ships, yachts, or boats to take on board and tend the sick and wounded.
Vessels responding to the appeal, and also vessels which have of their own accord rescued sick, wounded, or ship-wrecked men, shall enjoy special protection and certain immunities. In no case can they be captured for having such persons on board, but, apart from special undertakings that have been made to them, they remain liable to capture for any violations of neutrality they may have committed.
