This is the story of fire team leader Marcus Luttrell, the sole survivor of Operation Redwing, and the desperate battle in the mountains that led, ultimately, to the largest loss of life in Navy SEAL history. But it is also, more than anything, the story of his teammates, who fought ferociously beside him until he was the last one left-blasted unconscious by a rocket grenade, blown over a cliff, but still armed and still breathing. Over the next four days, badly injured and presumed dead, Luttrell fought off six al Qaeda assassins who were sent to finish him, then crawled for seven miles through the mountains before he was taken in by a Pashtun tribe, who risked everything to protect him from the encircling Taliban killers.
