Not all Auschwitz trains went to Auschwitz In connection with the death camps, I would note that some point before reaching Auschwitz (and also Treblinka), the cars of the trains coming from countries such as France, Belgium, and the Netherlands were decoupled.
Some cars went to Auschwitz, and some went to other places in the East, including the German-administered Ukraine and Transnistria.
According to a document from 1942, 26,200 French, Belgian, and Dutch Jews were shipped to Transnistria up to some time in the summer (?) of 1942. Most Belgian Jews deported in 1942, allegedly to Auschwitz, apparently reached Transnistria. Reports from 1943, indicate the arrival of Jews from Theresienstadt to Transnistria. These people had been sent to the "model ghetto" from Germany, Austria, Slovakia, and perhaps Bohemia and Moravia (I do not remember the details, although I have the sources). The reports also indicate the sending of Bulgarian Jews to Transnistria (not all of them went to Treblinka) in 1943, as well as the deportation and execution of Polish Jews by the Germans in Transnistria.
A follow-on discussion provided more information but also included a dismissal of the evidence from a certain Mr. Ioanid of the USHMM:
"A telegram sent on June 22, 1942, by Ambassador [Jacques] Truelle [the wartime French Ambassador in Bucharest] to Paris reports that 8,600 Jews from Holland, 11,600 Jews from France, and 7,000 Jews from Belgium have been sent by the Germans to this region [i.e., Transnistria - G.P.] The entire operation of this slow process of putting people to death, a little known aspect of the Final Solution, is found here outlined in an arresting manner:
'Transport seems to have taken place under horrendous conditions, and neither children, the old, nor women were spared. The Jews were apparently housed in ruined barracks where German troops had previously been quartered. Their plight is worse than wretched. They have brought with them only 50 kilograms of baggage and 10 marks per person. The German and Romanian authorities use them for various kinds of work without feeding them or paying them. No one is let off, not even the sick or children, who even if they are only eight years old are treated as adults. As a result of this kind of particularly cruel treatment, mortality rates are about 30 percent per day. Among other things, various contagious diseases are beginning to show up in view of the primitieve housing conditions, without any hygienic facilities whatsoever. On June 13, the Romanian authorities on their own sent 4,683 Jewish men, women and children away from Cernauti'"
In term so called the deportation of the Jews from Western Europe to Transnistria there is no documentary evidence proving that Jews deported from various Western or Central European countries arrived to Transnistria.
There is one exception, a document from Quai d'Orsay, mentioning an unsubstantiated rumor in this sense.
My affirmation is based on about 800,000 war time documents originating from various Romanian, Moldavian and Ukrainian archives which exist on microfilm in our Museum. Alexianu the governor of Transnistria was very much worried and aware about every new transport of Jews deported to Transnitria. Again no trace of these Jews in the territory under his administration. Finally not one survivor from Transistria mentions the arrival of the Jews from Central and Western Europe in this territory.
Revisionists have always been confronted with the problem of accounting for the fate of tens of thousands of deported Western Jews. For instance, we know that of approximately 97,000 Jews from France, Holland and Belgium deported eastwards by the end of 1942, only 31,000 were registered in Auschwitz. In addition, several thousand, who detrained at Cosel (50km west of Auschwitz) are said to have been employed by the Organisation Schmelt in Upper Silesia. The shortfall is over 50,000.
We don't know on what information the estimates for the workers with Organisation Schmelt are based. We think its possible that thousands more Jews may have been used there. Another possibility is that those unemployable Jews, assumed to have been gassed in Auschwitz, were actually settled in the Lublin region, as were many of the Slovakian Jews deported that year.
Naturally, if we could trace up to 25,000 Western Jews to Transnistria that would be a significant development and would certainly deal a serious blow to the standard Auschwitz history.
