From a critically acclaimed and #1 internationally bestselling author, the most riveting WWII story of Churchill's legendary SAS, the special forces unit of the British Army, chronicling one close-knit band of warriors from the SAS foundation through to the Italian landings—which truly turned the tide of war.

In 1941, as World War Two raged, scores of men stepped forward to answer Winston Churchill’s call for volunteers for Special Service, a high-risk opportunity to undertake the most hazardous, top-secret duties of war. Comprised of some of the finest fighting units in the entire British Army, these warriors longed to leave behind their mind-numbing garrison duties for battle. They hungered to pit themselves against a seemingly omnipotent enemy and brave a bloody and bruising baptism by fire. A rightfully proud regiment with an unrivalled esprit de corps, they were disavowed as unruly by top brass, unyieldingly vaunted by Churchill, and courageously loyal to the clandestine “butcher and bolt” raids that made their sacrifices—and their triumphs—legendary. But even as the combat-worn ranks of the SAS risked all to deliver the first resounding defeats on Nazi Germany, there were well-founded fears that their fortunes would change.

In Brothers in Arms, Damien Lewis pays tribute to the mavericks and visionaries who founded elite-forces soldiering—the SAS. Exhaustively researched from an invaluable trove of never-before-seen documents, wartime letters, diaries, mission reports, rare photos, undeveloped film, plus interviews with WWII veterans and their surviving families, Damien follows one close-knit band of men from the founding of the SAS through to the Italian landings, which truly turned the tide of the war. It is a breathtaking narrative of do-or-die action and unbelievable daring chronicling the exploits of some of the most fearless, revered, and under-the-radar soldiers of the 20th century.
