Allied troops invaded North Africa in November 1942. By that time, the Germans had opened six killing centers in Nazi-occupied Poland and already had murdered four million Jews, most by gassing or mass shootings. Hundreds of thousands of Jews and others also were imprisoned in concentration camps throughout the Third Reich.

When the western Allied armies landed in Normandy, France, on D-Day (June 6, 1944), more than five million Jews had been murdered, and only two killing centers—Majdanek and Auschwitz—were still operating. Both were liberated by Soviet troops. US military forces never encountered the Nazi killing centers.

This five-minute film shows the movement of Allied troops between 1942 and 1945 and the location of the killing centers.
