I am finding the book very interesting and informative, and can recommend it to forum members who can read German. I myself looked it up on the recommendation of Hans.
I was gratified to see that Aly and Gerlach support the position that I have previously taken in this forum, namely that the primary German motive in deporting Jews from Hungary was to obtain slave labour rathr than extermination per se. The two authors show how the lead-up to the deportation was determined by German efforts to induce the Hungarian Government to hand over up to 100,000 fit Hungarian Jews capable of forced labour, and how the Hungarian Government insisted that the Germans take all the Jews, not just those who could be used for labour. Furthermore, the Hungarian Government to a certain extent frustrated the German efforts to obtain usable Jewish labour by retaining 80,000 Jewish men of military age in the Auxiliary Labour Service. As a result, the German staff at Auschwitz found itself lumbered with a large number of unemployables that had to be disposed of by the usual methods.
Aly and Gerlach's material also supports me on another point. I had previously argued that some 100,000 Jews deported from Hungary to Auschwitz had been made available to the Jaegerstab for the construction of subterranean aircraft factories. Certain members of the forum, proceeding from a dogmatic and ideologically-determined viewpoint, contested my argument, and claimed that the number could only have been a few thousand.
Here is what Aly and Gerlach write on page 296 of their book:
100,000 Hungarian Jews, used as forced labour by the Jaegerstab. Exactly the figure I have previously used.Noch schwerer wiegt die Nachkriegsaussage des ehemaligen Leiters des Arbeitsinsatzes im >>Jaegerstab<<, Fritz Schmelter, also eines wichtigen zustaendigen Funktionaers, etwa 100.000 ungarische Juden habe man als Zwangsarbeiter eingesetzt.
Even more weight must be given to the post-war statement of the director of labour-allocation in the "Jaegerstab", Fritz Schmelter, an important responsible functionary, that about 100,000 Hungarian Jews had been employed as forced labourers.
