Synopsis VIII — Conventions and Neutral Powers
A neutral Power may authorize the passage over its territory of the sick and wounded belonging to the belligerent armies, on condition that the trains bringing them shall carry neither personnel nor war material. In such a case, the neutral Power is bound to take whatever measures of safety and control are necessary for the purpose (Hague Conv. No. V, Art. 14). (Personnel and materials necessary to treat the sick and wounded are consequently authorized).
