Three defendants were acquitted. However, many of the Nazis who perpetrated the Holocaust were never tried or punished, including Hitler who had committed suicide. Since then, the international community has continued and improved accountability through forums such as the International Criminal Court, and the International Criminal Tribunal for Rwanda.
According to the Yad Vashem Holocaust Martyrs' and Heroes' Remembrance Authority in Jerusalem, "[a]ll the serious research" confirms that between five and six million Jews died.[391] Early postwar calculations were 4.2 to 4.5 million from Gerald Reitlinger;[392] 5.1 million from Raul Hilberg; and 5.95 million from Jacob Lestschinsky.[393] In 1986 Lucy S. Dawidowicz used the pre-war census figures to estimate 5.934 million.[394] Yehuda Bauer and Robert Rozett in the Encyclopedia of the Holocaust (1990) estimated 5.59–5.86 million.[395] A 1996 study led by Wolfgang Benz suggested 5.29 to 6.2 million, based on comparing pre- and post-war census records and surviving German documentation on deportations and killings.[391] Martin Gilbert arrived at a minimum of 5.75 million.[396] The figures include over one million children.[397]
They set off at 11 p.m., in groups of ten. The first group emerged from the tunnel without incident. Zeidel recalled slithering on his stomach toward the edge of the camp.

Dogim attributed it to a blur of movement spotted by the guards.

Mengele was born on 16 March 1911 to Walburga (née Hupfauer) and Karl Mengele in Günzburg, Bavaria, Germany.[4] He was the oldest of three children; his two younger brothers were Karl Jr. and Alois. Their father was founder of the Karl Mengele & Sons company, producers of farm machinery.[5] Josef was successful at school and developed an interest in music, art, and skiing.[6] He completed high school in April 1930 and went on to study philosophy in Munich,[7] where the headquarters of the Nazi Party were located.[8] In 1931, Mengele joined the Stahlhelm, Bund der Frontsoldaten, a paramilitary organization that was absorbed into the Nazi Sturmabteilung (Storm Detachment; SA) in 1934.[7][9]
