On January 27, 1945, exactly 80 years ago, the Auschwitz concentration camp was liberated by the Soviet Red Army. It was the largest of the Nazi death camps: 1.3 million people were sent to Auschwitz over the course of the war, out of which 1.1 million were killed, 90 percent of them Jewish. In 1940, to gather intel on the murky inner workings of Auschwitz, the Polish resistance arranged for an army captain named Witolf Pilecki to be sent to spy on the camp from the inside. Using dramatized reenactments and fast-paced storytelling, a new podcast tells the fascinating story of Pilecki’s three years in the camp, during which he organized an inner camp resistance group and smuggled valuable information back to the Allies before eventually escaping in 1943. A dramatic story of bravery in the face of profound evil. —Paulina Prosnitz
