Ohrdruf was a slave labor subcamp of Buchenwald that opened in late 1944. Its 10,000 prisoners built railroad lines and dug tunnels.

As U.S. forces advanced in early April 1945, SS guards forced prisoners on a death march out of Ohrdruf. The Americans discovered piles of bodies, some smoking on half-burned pyres, others stacked in sheds. They found the remains of over 9,000 people in mass graves.

Ohrdruf was the first camp that U.S. troops liberated. Generals Eisenhower, Bradley, and Patton visited the site in order to view the evidence and ensure that the world learned of the atrocities.

"We had known. The world had vaguely heard. But until now no one of us had looked on this . . . It was as though we had penetrated at last to the center of the black heart, to the very crawling inside of the vicious heart."
Novelist and war correspondent Meyer Levin describing his April 1945 visit to Ohrdruf

"It made me ashamed to be a member of the human race."

The Nazis murdered almost 60,000 people at Buchenwald, one of the largest concentration camp complexes. At the height of the war, 110,000 slave laborers worked in factories and quarries at 87 subcamps.

As American forces approached Buchenwald in April 1945, SS guards evacuated almost 40,000 prisoners. One third died on death marches.

On April 11, 1945, the remaining prisoners took control of Buchenwald. Shortly thereafter, U.S. soldiers of the 3rd Infantry Division found more than 20,000 survivors.

"The things I saw beggar description . . . The visual evidence and the verbal testimony of starvation, cruelty and bestiality were . . . overpowering . . . I made the visit deliberately in order to be in a position to give firsthand evidence of these things if ever, in the future, there develops a tendency to charge these allegations merely to 'propaganda.'"
