International Committee of the Red Cross The most reliable primary source on the role of the Red Cross during World War II are the three volumes of the "Report of the International Committee of the Red Cross on its activities during the second world war (September 1, 1939 – June 30, 1947)" written by the International Committee of the Red Cross itself. The report can be read online. The legal basis of the work of the ICRC during World War II was the Geneva Conventions in their 1929 revision. The activities of the Committee were similar to those during World War I: visiting and monitoring POW
International Committee of the Red Cross during an armed conflict was adopted by the International Red Cross Conference. Unfortunately, most governments had little interest in implementing this convention, and it was thus prevented from entering into force before the beginning of World War II. In the Interwar period, Bolivia and Paraguay were disputing possession of the Gran Chaco - a desert region between the two countries. The dispute escalated into a full-scale conflict in 1932. During the war the ICRC visited 18,000 Bolivian prisoners of war and 2,500 Paraguayan detainees. With the help of the ICRC both countries made improvements to the conditions of the detainees.
