A major army, 400,000 strong, made a major difference in World War 2. Yet it doesn’t get enough attention in the West (nor, unfortunately, on this podcast). It’s the Armia Krajowa, the Polish Home Army. From exposing the Holocaust, to breaking the German Enigma Code, to helping destroy V-2 rockets, the AK bridged the Eastern and Western Fronts of the Second World War.
