I’d seen the 1975 film Operation Daybreak and was aware of the assassination of Reinhard Heydrich, but what I wasn't aware of was the utter destruction of the village of Lidice as an act of vengeance and how the Staffordshire miners helped with the rebuilding of the village after the war. That was until Russell Phillips shot me an email.
Russell's book is A Ray of Light: Reinhard Heydrich, Lidice and the North Staffordshire Miners. Its not a long read but is a book that everyone should read!
