In the winter of 1941 an alien-seeming object was captured by an RAF reconnaissance pilot flying a lone unarmed Spitfire across the French coast. Balanced upon the cliffs near Le Havre was what appeared to be a giant convex dish, directed across the Channel at the war-torn British coastline. Might the dish constitute a highly secret form of radar – one that had the capacity to tip the balance of the war in the enemy’s favour? A top-secret mission was devised to steal what had become known as the ‘Wurzburg Dish’ after Enigma intercepted coded German messages. Appropriately christened Operation Biting, this was to be the first-ever Allied raid using airborne forces. Relying on files declassified for the purposes of writing this book, eyewitness testimony, and working with the families of key figures involved, Lewis reveals an untold epic of daring, ruthless rule-breaking and ferocity.
