General Kaltenbrunner relates to Major Dorf that when Reinhard Heydrich died, he was having death bed rantings and begging forgiveness for crimes against the Jews. In reality, when Heydrich died in 1942 he was in a coma and died in his sleep.
The scene of the day before the liberation of Auschwitz is shown just before the scene of the Sobibor uprising. Auschwitz was liberated in January 1945 and the Sobibor uprising took place in October 1943.
We're shown the Sobibor revolt very shortly before we see the Third Reich having completely fallen. In fact, the revolt occurred on October 14, 1943 - 19 months prior to the May surrender.
