When troops liberated the concentration camps they were unprepared for what they encountered. Here a U.S. soldier holds a victim of Nazi terror sobbing in relief of his liberation.

Jewish women and girls await execution at a mass grave in Skede, Latvia. Made to strip down to underclothes as they waited, the women were told to approach the lip of the grave in groups of ten. They were there forced to strip naked, before being shot. Many did not die from the gunshot, but bled to death, or were smothered by the weight of bodies that fell on top of them. In groups of ten, 2,800 human beings were killed between December 15 and 17, 1941.

“The world must know what happened, and never forget.” At the end of the Second World War, General Ike Eisenhower made the decision to personally visit as many Nazi concentration camps as he possibly could. His reason? He felt compelled to document the camps, their appalling conditions, and the brave souls who survived them. He anticipated a time when the Nazi atrocities might be downplayed or even denied, and as such ordered the filming and photographing of camps as they were liberated.

A group of young children gaze out at the photographer just prior to their execution by an Einsatzkommando. An estimated one million Jewish children died in the Holocaust, most of them in the gas chambers of the death camps. As the Germans swept into Soviet territory, they sometimes turned the task of killing Jewish children over to their Ukrainian allies.

In the early years of Nazi Germany, Hitler ordered the euthanasia program, codenamed Aktion T4, to eliminate those “unworthy of life”. The first series of murders were by starvation, then lethal injection before finally evolving to the gas chamber and cremation. Unlike in the concentration camps doctors, not soldiers, were put in charge of deciding those who were executed. Over 400,000 Germans were sterilized while just about 200,000 were exterminated for having various mental disabilities.

On 2 July 1942, most of the children of Lidice, a small village in what was then Czechoslovakia, were handed over to the Łódź Gestapo office. Those 82 children were then transported to the extermination camp at Chełmno 70 kilometers away. There they were gassed to death. This remarkable sculpture by by Marie Uchytilová commemorates them.

Murder Most Foul, The ghoulish tale of a family of serial killers known as the "Bloody Benders". Innkeepers who murdered their guests to steal their belongings. They would seat them with their backs to a draped doorway. A member of the family would bash in their brains with a hammer, then slit their victims throat after they fell to the floor. More then a dozen men, women, children lost their lives, and were found in mass graves days after the Bender's escaped, never to be brought to justic...
