As the reality of atrocities in Ukraine continues to be uncovered, we look back at a massacre of Polish officers in the Second World War, the truth of which continues to be exposed to this day. Under the orders of Stalin, the NKVD underwent a secret operational order, which to this very day is still being exposed. For almost fifty years, the Soviet regime's fiction of Katyn being a Nazi atrocity was unchallenged, with decades passing the search for the truth continues. In this episode, writer and filmmaker Jane Rogoyska joins James once again on Warfare. As the author of Surviving Katyn: Stalin's Polish Massacre and the Search for Truth, Jane takes us through the results of decades-long efforts to unearth answers; as we focus on the experience of the few survivors and newly-opened archives.
