On 12 March 1945, ICRC president Jacob Burckhardt was told by SS General Ernst Kaltenbrunner that the ICRC's delegates could visit the concentration camps, but the 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), visited the camps.
