Book excerpt: From Damien Lewis, bestselling author and award-winning historian and war reporter, comes the thrillingly told stories of seven dramatic and epic WWII escapes executed by members of one of the world’s legendary military fighting forces: the British Special Air Service. No food. No water. Out of ammo. Hunted and on the run. The dreaded certainty of discovery looming between recapture and safe haven. What would you do? Give up? For the seven heroes of Churchill’s Great Escapes the answer was simple: keep moving against all odds. These are the extraordinary stories of the bravery and endurance of the men of SAS, legendary pioneers of escape and evasion who, through the darkest of days and nights of World War II, endeavored and succeeded in slipping through the clutches of the enemy. Based on in-the-moment personal diaries and notebooks, mission reports, debriefings and letters, Damien Lewis recounts the most terrifying and adrenaline-fueled days and nights in the lives of men for whom survival was the only option. We follow every desperate step, facing unknowable threats and death around every corner, and share in the breathtaking endurance that brought them freedom against the most formidable of threats: the seemingly invincible Nazi war machine.
