Facing a wall of flames and shellfire, Army medic Desmond Doss had to make an agonizing decision -- retreat with his 77th Infantry Division or stay behind to save the wounded.

On the big screen, this true story is the stuff of Academy Award nominations. The "Hacksaw Ridge" script gave actor Best Actor nominee Andrew Garfield few words to say, but his face had to display shock, confusion, doubt and determination. The film has been nominated for six Oscars, including Best Picture.

"What is it you want from me?", Doss prays, in his slow Virginia mountains drawl. "I don't understand. I can't hear you."

Then a distant voice in the flames screams: "Medic! Help me!"

Doss quietly says, "Alright," and runs back into the flames.

Working alone, Doss -- who refused a weapon, because of his Seventh-day Adventist convictions -- lowered at least 75 injured men over a 400-foot cliff during the World War II Battle of Okinawa. He collapsed several times during that night, but kept going with these words on his lips: "Please Lord, help me get one more."

A Japanese soldier later testified that he aimed at Doss several times, but his rifle kept jamming when he tried to fire.

President Harry S. Truman presented Doss with the Medal of Honor on Oct. 12, 1945 -- the first conscientious objector to receive that honor. It took Doss years to recover from his war injuries -- he lost a lung to tuberculosis -- and he devoted his life to church work, dying in 2006 at age 87.

Doss should be listed among the "most heroic figures in American history. He was singular," said "Hacksaw Ridge" director Mel Gibson, during 2016 commencement rites at Liberty University in Lynchburg, Va., in the hills where Doss grew up.
