“HACKSAW RIDGE is the extraordinary true story of Desmond Doss [Andrew Garfield] who, in Okinawa during the bloodiest battle of WWII, saved 75 men without firing or carrying a gun. He was the only American soldier in WWII to fight on the front lines without a weapon, as he believed that while the war was justified, killing was nevertheless wrong. As an army medic, he single-handedly evacuated the wounded from behind enemy lines, braved fire while tending to soldiers and was wounded by a grenade and hit by snipers. Doss was the first conscientious objector awarded the Congressional Medal of Honor.”
Desmond Thomas Doss (February 7, 1919 March 23, 2006) was the first conscientious objector to receive the Medal of Honor and one of only three so honored (the others are Thomas W. Bennett and Joseph G. LaPointe, Jr.). He was a Corporal (Private First Class at the time of his Medal of Honor heroics) in the U.S. Army assigned to the Medical Detachment, 307th Infantry, 77th Infantry Division.

The trailer says it was the bloodiest battle of WWII. Okinawa, nightmare that it was, doesn’t even make the top 10. Horrifying.
