Assassins and Secret Listeners: Britain's Invisible Armies, 1939-45

Uncover the story of a nation's hidden heroes.

Throughout Britain, all day, every day and in the dead of night, the secret listeners went about their solitary work. Hands on headphones, these men and women, drawn from all walks of civilian life, listened to the coded messages of German intelligence and passed hundreds of thousands of them on to Bletchley Park.

At the same time, men with firearms experience were recruited into secret patrols trained in sabotage and silent killing with knife or garotte. In June 1940, with a full-scale German invasion expected any minute, these auxiliary units were poised to undertake suicidal missions attacking enemy supply lines and assassinating anyone who helped the Nazis. In preparation for this, they dug operational bases in remote and hidden places – the ruins of many still exist today – and stashed them with supplies and weapons.

Alistair Moffat tells the half-forgotten stories of immense bravery by thousands of ordinary men and women. Sworn to secrecy, their heroic work has long been overlooked, yet it played a crucial part in the Allied victory in 1945. This book finally pays them their due.
