Kaufering was a system of eleven subcamps of the Dachau concentration camp located around the town of Landsberg am Lech in Bavaria, which operated between 18 June 1944 and 27 April 1945. Previously, Nazi Germany had deported all Jews from the Reich, but having exhausted other sources of labor, Jews were deported to Kaufering to create three massive underground bunkers, , Diana II, and Walnuss II, which would not be vulnerable to the Allied bombing which had devastated German aircraft factories. The bunkers were intended for the production of Messerschmitt Me 262 aircraft, but none were produced at the camps before the United States Army captured the area.
