In February 1944, the French Resistance in the Amiens area was in turmoil. Its strength had been decimated by German aggression and the work of a number of traitors in their midst, and hundreds of its members languished in the city's formidable jail, awaiting an almost certain death at the hands of their captors. When two Allied intelligence officers were incarcerated alongside them it became clear that immediate action was imperative. What followed was a precision air attack on the prison, of hitherto unrivalled daring, carried out by the RAF's elite 2nd Tactical Air Force. This text presents the true story behind one of the most audacious raids of World War II.
