Operation Crossbow : The Untold Story of the Search for Hitler’s Secret Weapons

The story of the photographic intelligence work undertaken from a country house at Medmenham, Buckinghamshire, is one of the great lost stories of the Second World War .At its peak in 1944, almost 2,000 British and American men and women worked at the top-secret Danesfield House, interpreting photographs - the majority stereoscopic so they could be viewed in 3D - to unlock secrets of German military activity and weapons development.Millions of aerial photographs were taken by Allied pilots, flying unarmed modified Spitfires and Mosquitos on missions over Nazi Europe. it was said that an aircraft could land, the photographs be developed and initial interpretation completed within two hours - marking the culmination of years of experiments in aerial intelligence techniques. Their finest hour began in 1943, during the planning stages of the Allied invasion of Europe, when Douglas Kendall, who masterminded the interpretation work at Medmenham, led the hunt for Hitler's secret weapons.Opera
