Art. 13. Prisoners of war who do not yet come under the conditions prescribed in Articles 1-5 shall be repatriated or interned in Switzerland, as the case may be, as rapidly as the prescribed conditions are fulfilled. Art. 14. Officers in sound health who are interned in Switzerland either under the present agreement or under the Berne agreement of March 15, 1918, cannot be repatriated save in exceptional cases and solely for serious illness or accident. Art. 16. Article 19 of the Berne convention of March 15, 1918, concerning the employment of repatriated soldiers shall be applicable to prisoners benefiting from the present agreement. Released Belgian prisoners can be employed in France under the same conditions as repatriated French prisoners. Art. 17. All the foregoing provisions are to apply to German prisoners of war captured by Belgian troops and to Belgian prisoners taken by German troops. The Belgian officers, sub-officers, and soldiers shall be included in the repatriated and interned French groups in the proportion of one Belgian for ten Frenchmen, up to the exhaustion of the number of German war prisoners who were captured by Belgian troops and who come under the foregoing provisions. Art. 18. In the repatriation and internment of prisoners under Articles 1-5 only men in sound health are to be counted. Ill or wounded prisoners will continue to be repatriated directly or interned in Switzerland under the conditions laid down under Articles 7-18 of the Berne agreement of March 15, 1918. Art. 20. The provisions contained in Articles 1-19 of the present convention shall cease to be in force on Aug. 1, 1919, if one of the two Governments shall have given notice to that effect to the Swiss Political Department before May 1, 1919. FOOD FOR PRISONERS The articles following those just summarized relate to the treatment of prisoners remaining in captivity. The most important are these: Art. 25. The daily rations of officers must be sufficient in quantity and quality, especially as regards meat, vegetables, and seasoning, after taking into account the food restrictions imposed upon the civil population. The management of food supplies by the prisoner officers themselves is to be favored in every way. Art. 26. The daily rations allotted to imprisoned privates in Germany and in France must contain a minimum of 2,000 calories for men not working, 2,500 calories for ordinary workers, and 2,850 calories for prisoners doing heavy work. Art. 27. Prisoners of war shall, in general, receive the same ration of meat as the civil population.
