Convention (X) for the Adaptation to Maritime Warfare of the Principles of the Geneva Convention. The Hague, 18 October 1907.
Art. 5. Military hospital ships shall be distinguished by being painted white outside with a horizontal band of green about a metre and a half in breadth.
The ships mentioned in Articles 2
shall be distinguished by being painted white outside with a horizontal band of red about a metre and a half in breadth.
The boats of the ships above mentioned, as also small craft which may be used for hospital work, shall be distinguished by similar painting.
All hospital ships shall make themselves known by hoisting, with their national flag, the white flag with a red cross provided by the Geneva Convention, and further, if they belong to a neutral State, by flying at the mainmast the national flag of the belligerent under whose control they are placed.
Hospital ships which, in the terms of Article 4
, are detained by the enemy must haul down the national flag of the belligerent to whom they belong.
The ships and boats above mentioned which wish to ensure by night the freedom from interference to which they are entitled, must, subject to the assent of the belligerent they are accompanying, take the necessary measures to render their special painting sufficiently plain.
