"Hacksaw Ridge" follows a fairly linear and predictable narrative based on a true story, so its power lies not in plot twists, but in the execution of its foretold events. The film's climax occurs after the American forces are driven from the ridge in a bloody retreat, leaving dozens of wounded behind. The turning point is Desmond's decision to stay behind alone. Under the cover of darkness and constant enemy fire, he begins his seemingly impossible mission. He rigs a rope system and, one by one, finds and lowers approximately 75 wounded soldiers down the cliff face to safety. His repeated prayer, "Please Lord, help me get one more," becomes the film's emotional core.
His actions completely transform his reputation within the unit. The men who once beat him now see him as a savior. In a pivotal moment before the final assault, the entire company delays their attack to wait for Doss, their new spiritual touchstone, to finish his Sabbath prayers. During this final battle, Desmond's bravery continues as he saves more men, including his former tormentor, Smitty Ryker (who dies from his wounds), and Captain Glover. In an ambush, Desmond is wounded by a grenade blast. The film ends with his evacuation; as he is lowered from the cliff, he is clutching the Bible Dorothy gave him. The final scenes feature archival footage and interviews with the real, elderly Desmond Doss and some of the men he saved, powerfully reinforcing the truth of the extraordinary events depicted. President Harry S. Truman is shown awarding Doss the Medal of Honor, the first ever given to a conscientious objector.
