WW2: The Secret British Resistance Warfare

What if the Battle of Britain had not been a success for the British? What was the plan had the Nazis successfully crossed the channel? Chris Pratt is the Curator of the Museum of the British Resistance Organisation, Parham Airfield. He joined James over a video call to talk about how the Auxiliary Units that made up the British resistance were formed, how they were trained and when, or whether, they came into use.
