The first transport of prisoners reached Kaufering train station on 18 June 1944. The 1,000 Hungarian Jews from the Auschwitz concentration camp were brought to the Kaufering III camp.

In July 1944, this was followed by further transportations with Lithuanian Jews from the Schaulen and Kaunas ghettos that were transformed into concentration camps. Polish and other Hungarian Jews, too, were brought to the Landsberg/Kaufering concentration subcamp complex, followed by smaller groups of Jewish concentration camp prisoners from other countries, including the Netherlands, France, Belgium, Italy, Greece, Latvia, the former Czechoslovakia and the German Reich.

It is proving difficult to obtain exact figures for prisoners from the Landsberg/Kaufering concentration subcamp complex because the surviving documents and reports are incomplete. According to the most recent research, some 23,500 people were detained in all camps of the Landsberg/Kaufering concentration subcamp complex. More than 6,500 people – known by name – perished in the Kaufering camps.
