At the end of WWII, impending Allied victory was sobered by the grim facts of the atrocities which allied troops were uncovering all over Germany. Margaret Bourke-White was with General Patton’s third amy when they reached Buchenwald on the outskirts of Weimar. Patton was so incensed by what he saw that he ordered his police to get a thousand civilians to make them see with their own eyes what their leaders had done. The MPs were so enraged they brought back 2,000. Bourke-White said, “I saw and photographed the piles of naked, lifeless bodies, the human skeletons in furnaces, the living skeletons who would die the next day… and tattoed skin for lampshades. Using the camera was almost a relief. It interposed a slight barrier between myself and the horror in front of me.”
LIFE magazine decided to publish these photos in their May 7, 1945 issue many photographs of these atrocities, saying, “Dead men will have indeed died in vain if live men refuse to look at them.”
