The ICRC and World War II

The legal basis of the work of the ICRC during World War II were the Geneva Conventions in their 1929 revision. The activities of the Committee were similar to those during World War I: visiting and monitoring POW camps, organizing relief assistance for civilian populations, and administering the exchange of messages regarding prisoners and missing persons. By the end of the war, 179 delegates had conducted 12,750 visits to POW camps in 41 countries. The Central Information Agency on Prisoners-of-War (Zentralauskunftsstelle für Kriegsgefangene) had a staff of 3,000, the card index tracking prisoners contained 45 million cards, and 120 million messages were exchanged by the Agency. One major obstacle was that the Nazi-controlled German Red Cross refused to cooperate with the Geneva statutes including blatant violations such as the deportation of Jews from Germany and the mass murders conducted in the Nazi concentration camps. Moreover, two other main parties to the conflict, the Soviet Union and Japan, were not party to the 1929 Geneva Conventions and were not legally required to follow the rules of the conventions.

During the war, the ICRC failed to obtain an agreement with Nazi Germany about the treatment of detainees in concentration camps, and it eventually abandoned applying pressure in order to avoid disrupting its work with POWs. The ICRC also failed to develop a response to reliable information about the extermination camps and the mass killing of European Jews, Roma, et al. This is still considered the greatest failure of the ICRC in its history.[citation needed] After November 1943, the ICRC achieved permission to send parcels to concentration camp detainees with known names and locations. Because the notices of receipt for these parcels were often signed by other inmates, the ICRC managed to register the identities of about 105,000 detainees in the concentration camps and delivered about 1.1 million parcels, primarily to the camps Dachau, Buchenwald, Ravensbrück, and Sachsenhausen.

It is known that Swiss army officer Maurice Rossel during World War II had been sent to Berlin as a delegate of the International Red Cross, as such he visited Auschwitz 1943 and Theresienstadt 1944. Claude Lanzmann made him talk about his experience in 1979, producing a documentary entitled Visitor from the living.

On March 12, 1945, ICRC president Jacob Burckhardt received a message from SS General Ernst Kaltenbrunner accepting the ICRC's demand to allow delegates to visit the concentration camps. This agreement was bound by the condition that these delegates would have to stay in the camps until the end of the war. Ten delegates, among them Louis Haefliger (Camp Mauthausen), Paul Dunant (Camp Theresienstadt) and Victor Maurer (Camp Dachau), accepted the assignment and visited the camps. Louis Haefliger prevented the forceful eviction or blasting of Mauthausen-Gusen by alerting American troops, thereby saving the lives of about 60,000 inmates. His actions were condemned by the ICRC because they were deemed as acting unduly on his own authority and risking the ICRC's neutrality. Only in 1990, his reputation was finally rehabilitated by ICRC president Cornelio Sommaruga.

Another example of great humanitarian spirit was Friedrich Born (1903–1963), an ICRC delegate in Budapest who saved the lives of about 11,000 to 15,000 Jewish people in Hungary. Marcel Junod (1904–1961), a physician from Geneva, was another famous delegate during the Second World War. An account of his experiences, which included being one of the first foreigners to visit Hiroshima after the atomic bomb was dropped, can be found in the book Warrior without Weapons.

In 1944, the ICRC received its second Nobel Peace Prize. As in World War I, it received the only Peace Prize awarded during the main period of war, 1939 to 1945. At the end of the war, the ICRC worked with national Red Cross societies to organize relief assistance to those countries most severely affected. In 1948, the Committee published a report reviewing its war-era activities from September 1, 1939 to June 30, 1947. Since January 1996, the ICRC archive for this period has been open to academic and public research.
