In the dust and blazing heat of Helmand, the young men of 16 Air Assault Brigade find themselves in the most relentless battles faced by British troops in recent history. As the only writer to have obtained unprecedented, unrestricted access to the front line, Sam Kiley is with them to bear witness to the most intense challenges of their lives. "Desperate Glory" is an unflinching portrait of the reality of war - the bombs, the shooting and the daily struggles that push them to the very limit of human endurance.
