In this vivid account of the U.S. Army's legendary 10th Mountain Division's heroic stand in the mountains of Afghanistan, Captain Sean Parnell shares an action-packed and highly emotional true story of triumph, tragedy, and the extraordinary bonds forged in battle. At twenty-four years of age, U.S. Army Ranger Sean Parnell was named commander of a forty-man elite infantry platoon-a unit that came to be known as the Outlaws-and was tasked with rooting out Pakistan-based insurgents from a mountain valley along Afghanistan's eastern frontier. Parnell and his men assumed they would be facing a ragtag bunch of civilians, but in May 2006 what started out as a routine patrol through the lower mountains of the Hindu Kush became a brutal ambush. Barely surviving the attack, Parnell's men now realized that they faced the most professional and seasoned force of light infantry the U.S. Army had encountered since the end of World War II. What followed was sixteen months of close combat, over the course of which the platoon became Parnell's family.
