Art. X. Any merchantman, to whatever nation she may belong, charged exclusively with removal of sick and wounded, is protected by neutrality, but the mere fact, noted on the ship’s books, of the vessel having been visited by an enemy’s cruiser, renders the sick and wounded incapable of serving during the continuance of the war. The cruiser shall even have the right of putting on board an officer in order to accompany the convoy, and thus verify the good faith of the operation.
If the merchant ship also carries a cargo, her neutrality will still protect it, provided that such cargo is not of a nature to be confiscated by the belligerents.
The belligerents retain the right to interdict neutralized vessels from all communication, and from any course which they may deem prejudicial to the secrecy of their operations. In urgent cases, special conventions may be entered into between commanders-in-chief, in order to neutralize temporarily and in a special manner the vessels intended for the removal of the sick and wounded.
Art. XI. Wounded or sick sailors and soldiers, when embarked, to whatever nation they may belong, shall be protected and taken care of by their captors.
Their return to their own country is subject to the provisions of Article VI. of the convention, and of the additional Article V.
Art. XII. The distinctive flag to be used with the national flag, in order to indicate any vessel or boat which may claim the benefits of neutrality, in virtue of the principles of this convention, is a white flag with a red cross. The belligerents may exercise in this respect any mode of verification which they may deem necessary.
Military hospital ships shall be distinguished by being painted white outside, with green strake.
Art. XIII. The hospital ships which are equipped at the expense of the aid societies, recognized by the governments signing this convention, and which are furnished with a commission emanating from the sovereign, who shall have given express authority for their being fitted out, and with a certificate from the proper naval authority that they have been placed under his control during their fitting out and on their final departure, and that they were then appropriated solely to the purpose of their mission, shall be considered neutral, as well as the whole of their staff. They shall be recognized and protected by the belligerents.
They shall make themselves known by hoisting, together with their national flag, the white flag with a red cross. The distinctive mark of their staff, while performing their duties, shall be an armlet of the same colors.
The outer painting of these hospital ships shall be white, with red strake.
