On April 29, 1945, the infamous Dachau Concentration Camp was liberated by US troops. The young American soldiers were the first allied witnesses to the Holocaust. The one-hour special will look back at the events of spring 1945 and tell the true story of the American GIs as they went on their final march across Germany to discover a place beyond all imagination or description. In their own words, some of the last living veterans as well as camp survivors vividly describe their experiences of the liberation and how these events have affected their lives.
