I had a dream last week that I was on a street in a small village in Poland. I've never been to Europe, much less Poland. But in the dream I recognized the street and thought "I'm in Poland!". Then I turned around and saw a distant fortress-like building with a big gate and a "watchtower" right over it. When I remembered the dream upon awaking I Googled "Death Camps" and sure enough there was the "fortress" EXACTLY as I dreamed it. It was Birkenau! I'm not even Jewish. I'm 61. Did have a strange fascination with The Holocaust as a child. I researched a lot of old photos online and found prisoner faces that closely resemble friends. Even found a face that looks a lot like I do now. I've never liked Nazis either.
As was the case in other camps, the primary form of voluntary music-making in Birkenau was singing.  Due to its size and international composition, there were inmates from all over Europe whose voices survivors remembered.  Prisoners sang to comfort one another, to build solidarity and to express resistance.  The former inmate Kitty Hart remembered that
The passengers had landing certificates and transit visas by the Cuban Director-General of Immigration, Manuel Benitez Gonzalez. But, a week before the ship left, Cuban President Federico Laredo Bru published a decree that overturned all recent landing certificates. For them to land in Cuba, they needed written authorization from the Cuban Secretaries of State and Labor and a $500 bond. Most of the passengers were not prepared for the bureaucratic mess they were about to face in Cuba.
Estimates of Jewish participation in partisan units throughout Europe range from 20,000 to 100,000.[323] In the occupied Polish and Soviet territories, thousands of Jews fled into the swamps or forests and joined the partisans,[324] although the partisan movements did not always welcome them.[325] An estimated 20,000 to 30,000 joined the Soviet partisan movement.[326] One of the famous Jewish groups was the Bielski partisans in Belarus, led by the Bielski brothers.[324] Jews also joined Polish forces, including the Home Army. According to Timothy Snyder, "more Jews fought in the Warsaw Uprising of August 1944 than in the Warsaw Ghetto Uprising of April 1943".[327][r]
Recognising that battlefield conditions changed rapidly and that orders often became overtaken by events, the German army encouraged its commanders to make decisions without waiting for orders from above, thus allowing them to take advantage of fleeting opportunities as they arose. Above all else, this doctrine created aggressive and flexible leaders.
Although effective in quick campaigns against Poland and France, mobile operations could not be sustained by Germany in later years. Strategies based on manoeuvre have the inherent danger of the attacking force overextending its supply lines, and can be defeated by a determined foe who is willing and able to sacrifice territory for time in which to regroup and rearm, as the Soviets did on the Eastern Front (as opposed to, for example, the Dutch who had no territory to sacrifice). Tank and vehicle production was a constant problem for Germany; indeed, late in the war many panzer "divisions" had no more than a few dozen tanks.[75] As the end of the war approached, Germany also experienced critical shortages in fuel and ammunition stocks as a result of Anglo-American strategic bombing and blockade. Although production of Luftwaffe fighter aircraft continued, they would be unable to fly for lack of fuel. What fuel there was went to panzer divisions, and even then they were not able to operate normally. Of those Tiger tanks lost against the United States Army, nearly half of them were abandoned for lack of fuel.[76]
Instead, Marcel Goldberg, a Jewish “clerk” assigned to the new Plaszow commandant Arnold Buscher, played the largest role in compiling the transport list. It is generally agreed that Buscher, an SS officer, “could not have cared, within certain numerical limits, who went on the list,” according to Thomas Keneally. It’s also agreed that Goldberg engaged in a certain amount of corruption in who he added to the list and, moreover, that there was not even one “list” but rather different lists that emerged over a series of months.

In early 1942, mass exterminations were moved to two provisional gas chambers (the "red house" and "white house", known as bunkers 1 and 2) in Auschwitz II, while the larger crematoria (II, III, IV, and V) were under construction. Bunker 2 was temporarily reactivated from May to November 1944, when large numbers of Hungarian Jews were gassed.[161] In summer 1944 the combined capacity of the crematoria and outdoor incineration pits was 20,000 bodies per day.[162] A planned sixth facility—crematorium VI—was never built.[163] Prisoners were transported from all over German-occupied Europe by rail, arriving in daily convoys.[164] By July 1942, the SS were conducting "selections". Incoming Jews were segregated; those deemed able to work were sent to the selection officer's right and admitted into the camp, and those deemed unfit for labor were sent to the left and immediately gassed.[165] The group selected to die, about three-quarters of the total,[c] included almost all children, women with small children, the elderly, and all those who appeared on brief and superficial inspection by an SS doctor not to be fit for work.[167]

At the three Reinhard camps the victims were killed by the exhaust fumes of stationary diesel engines.[279] Gold fillings were pulled from the corpses before burial, but the women's hair was cut before death. At Treblinka, to calm the victims, the arrival platform was made to look like a train station, complete with fake clock.[300] Majdanek used Zyklon-B gas in its gas chambers.[301] In contrast to Auschwitz, the three Reinhard camps were quite small.[302] Most of the victims at these camps were buried in pits at first. Sobibór and Bełżec began exhuming and burning bodies in late 1942, to hide the evidence, as did Treblinka in March 1943. The bodies were burned in open fireplaces and the remaining bones crushed into powder.[303]
After some time off to recover in Zwittau, Schindler was promoted to second in command of his Abwehr unit and relocated with his wife to Ostrava, on the Czech-Polish border, in January 1939.[13] He was involved in espionage in the months leading up to Hitler's seizure of the remainder of Czechoslovakia in March. Emilie helped him with paperwork, processing and hiding secret documents in their apartment for the Abwehr office.[14] As Schindler frequently travelled to Poland on business, he and his 25 agents were in a position to collect information about Polish military activities and railways for the planned invasion of Poland.[15] One assignment called for his unit to monitor and provide information about the railway line and tunnel in the Jablunkov Pass, deemed critical for the movement of German troops.[16] Schindler continued to work for the Abwehr until as late as fall 1940, when he was sent to Turkey to investigate corruption among the Abwehr officers assigned to the German embassy there.[17]
