The courageous pilots of the Royal Air Force who faced the Luftwaffe in the Battle of Britain, affectionately known as 'the Few', are rightly hailed as heroes. Recently, efforts have been made to recognise the thousands who supported RAF operations behind the scenes. And yet one group remains missing from the narrative: the Women's Auxiliary Air Force. WAAFs worked within the Dowding System, the world's most sophisticated air defence network. Throughout the Blitz, they used radar to aid Fighter and Bomber Commands in protecting Britain's civilians. WAAFs were also behind the discovery of the terrifying German V-weapons. Their work was critical ahead of the Normandy landings and they were present in their hundreds at Bletchley Park. In this thrilling book, Sarah-Louise Miller celebrates their wartime contribution to British military intelligence. Hidden behind the Few but vital to their success, WAAFs supplied the RAF with life-saving information. Here, for the first time, is their story.
