Instructions for the Government of Armies of the United States in the Field (Lieber Code). 24 April 1863.
Section V : Safe-conduct -- Spies -- War-traitors -- Captured messengers -- Abuse of the flag of truce - Art. 87.
Art. 87. Ambassadors, and all other diplomatic agents of neutral powers, accredited to the enemy, may receive safe-conducts through the territories occupied by the belligerents, unless there are military reasons to the contrary, and unless they may reach the place of their destination conveniently by another route. It implies no international affront if the safe-conduct is declined. Such passes are usually given by the supreme authority of the State, and not by subordinate officers.
