From the award-winning historian, war reporter, and author Damien Lewis (Zero Six Bravo, Judy) comes the incredible true story of the top-secret "butcher-and-bolt" black ops units Prime Minister Winston Churchill tasked with stopping the unstoppable German war machine. Criminals, rogues, and survivalists, the brutal tactics and grit of these "deniables" would define a military unit the likes of which the world had never seen.

On a scorching September day in 1942, the Special Air Service (SAS), a special forces unit of the British Army, pulled off one of the most daring, top-secret ruses of the Second World War. The plan (sanctioned by Churchill): cover a grueling 2,000 miles of the Sahara desert to attack German general Erwin Rommel's seemingly impregnable port fortress in North Africa from the rear to break free and arm more than 30,000 Allied POWs.

On the night of June 13th, 1944, a 12-man SAS unit parachuted into occupied France. Their objective: hit German forces deep behind the lines, cutting the rail-tracks linking Central France to the northern coastline. In a country crawling with enemy troops, their mission was to prevent Hitler from rushing his Panzer divisions to the D-Day beaches and driving the Allied troops back into the sea. It was a Herculean task, but no risk was deemed too great to stop the Nazi assault.

‘Paddy' Mayne was one of the most outstanding special forces leaders of the Second World War. Hamish Ross's authoritative study follows Mayne from solicitor and a rugby international to troop commander in the Commandos and then the SAS, whose leader he later became and whose annals he graced, winning the DSO and three bars, the Croix de Guerre and the Légion d'Honneur.

Britain's Special Air Service - or SAS - was the brainchild of David Stirling, a young, gadabout aristocrat whose aimlessness in early life belied a remarkable strategic mind. Where most of his colleagues looked at a battlefield map of World War II's African theater and saw a protracted struggle with Rommel's desert forces, Stirling saw an opportunity: Given a small number of elite, well-trained men, he could parachute behind enemy lines and sabotage their airplanes and war matériel.
