Deportation:

The first step in the "Final Solution".

Jews were told they were going to be resettled for work
To Take some clothing, blankets, shoes, eating utensils (no knifes), a bowl, and some money.
Herded into trucks or forced to walk to the rail stations.
Forced into rail cars, windowless, unheated cattle cars (squeezed in so tight most were forced to stand-more than 120 people per car)
Doors sealed shut from the outside.
No drinking water, sanitary facilities
Many froze, suffocated to death or succumbed to disease during the trip to the camps.
The dead were not removed so they could be accounted for when they arrived at the camps.

Concentration Camps:

Upon arrival at a camp:

Inmates were usually stripped of all their valuables and clothes.
Shorn of body hair, disinfected, given a shower, and issued a striped prison uniform without regard to size.
Given a number (Auschwitz tattooed the number on their arms, not all did).
Roused from their barracks (housing 300-800 inmates each) at dawn.
Beds were slatted wood two and three tiers high, three to four prisoners shared each bunk (unable to stretch for normal sleep)
Inmates organized into groups to go to the toilets, marched to breakfast of some bread and a liquid substitute for tea or coffee (food rations did not permit survival for long)
Sent out to work for 10-14 hours in mines, factories, and road or airfield building, often in sub-zero weather or sever heat of summer.
Subjected to to constant physical and emotional harassment and beating.
Those who resisted orders were shot on the spot, roll calls were held often to assure no prisoners had escaped (all suffered if someone attempted an escape)

Places for mass murder:

No barracks for prisoners other than for workers.
Jews were made to think they were being resettled for labor, issued work permits, told to bring along their tools and exchange their German marks for foreign cuuency.
Food was also used to coax starving Jews onto the trains.
Upon arrival trucks transported those who were too weak to walk directly to the gas chambers.
Those able to walk were told they would have to be deloused and enter the baths.
Separated by sex and told to remove their clothes they entered the baths which in reality were the gas chambers. The shower heads were the inlets for poison gas.
Bodies removed by workers were burned in crematoria after the teeth of the victims were stripped for gold.

The Soviet troops were advancing:

Auschwitz prisoners were forced to march toward Germany
Approximately 20,000 of 58,000 prisoners died from exhaustion, starvation, cold, beatings, and executions.
