This week 66 years ago, Auschwitz concentration camp was liberated by Russian forces. Auschwitz was made up of two main camps, Auschwitz I and Auschwitz II (Birkenau), and became known as the most brutal Nazi concentration camp where over 1 million people, mostly Jews, were murdered through gas chambers, starvation, disease, and forced labor. Upon arrival at Birkenau, Jewish prisoners were immediately separated by gender and most were sent directly to the gas chambers to be killed and burned in crematoria, while a small minority were temporarily registered and held for slave labor until their deaths.

1. This week 66years ago, This concentration camp was liberated by Russian

3. One-sixth of all Jews murdered by the Nazis were gassed at Auschwitz.

6. It also had the worst, most inhuman conditions---and contained the complex's Gas Chambers and crematoria.

7. The mainly Jewish inmates who worked at that factory and others owned by German firms were pushed to the point of total exhaustion, at which time they were replaced by new laborers.

8. Auschwitz I and II were surrounded by electrically-charged four-meter high barbed wire fences, which were guarded by SS men armed with machine guns and rifles. The two camps were further closed in by a series of guard posts located two-thirds of a mile beyond the fences.

11. The camp's population constantly grew, in spite of the high mortality rate caused by exterminations, starvation, hard labour and contagious diseases.

12. Jewish people arrive at the platform in Birkenau.

13. Jewish people were thrown out of the train cars without their belongings.

14. The Jewish people were forced to make two lines, men and women separately.

15. SS officers would conduct selections among these lines, sending most victims to one side, condemning them to death in the gas chambers. A minority was sent to the other side, destined for forced labor. Those who were sent to their deaths were killed that same day and their corpses were burnt in the crematoria.

16. Those not sent to the gas chambers were taken to "quarantine," where their hair was shaved, they were given striped prison uniforms, and were registered as prisoners. Their registration numbers were tattooed on their left arms.

17. The daily schedule included waking at dawn, straightening one's sleep area, morning roll call, the trip to work, long hours of hard labor, standing in line for a pitiful meal, the return to camp, block inspection, and evening roll call. During roll call, prisoners were made to stand completely motionless and quiet for hours, in the thinnest of clothing, no matter what the weather. Whoever fell or even stumbled was sent to die. Each prisoner, in his own way, had to focus all his energy on just getting through the day's tortures.

18. Four chambers were in use at Birkenau, each with the potential to kill 6,000 people every day.

19. The chambers were built to look like shower rooms in order to confuse the victims: new arrivals at Birkenau were told that they were being sent to work, but first needed to shower and be disinfected.

21. By January 1945 Soviet troops were advancing towards Auschwitz.

23. All in all, some one million Jews had been murdered there.
