At the height of WWII, by pure accident the SAS stumbled upon the world’s first concentration camp found by the Allies. Unless it could be liberated, hundreds of inmates would be shipped into the heart of Nazi Germany, facing untold horrors. With audacity and lateral thinking to the fore, the SAS decided to hi-jack a train and to steam it over 100 kilometres behind enemy lines, to take the camp by complete surprise and rescue the inmates. At Chalke, I’ll be revealing the story behind this incredible true story – perhaps the greatest escape story of WW2 – and told in my book, SAS The Great Train Raid. I’ll also be speaking about my newly published volume of similarly incredible escape stories, SAS Great Escapes Five. Due to the nature of the unit, SAS patrols stood a very high chance of injury or capture behind enemy lines – and this in turn gave birth to the most amazing escape tales.
