interestingly, contrary to an assertion made by SanityCheck in another thread about the availability of information in the digital super age, these items appear to all be inaccessible on the internet.
I can not find the primary source material to review, in 2025...
I wanted to make sure my powder was dry and I had all of my facts and sources in order and cited before engaging in discourse on this subject with Bombsaway in the Aktion 1005 thread (the missing evidence was perpetually excused away with Aktion 1005). Unfortunately, without these primary sources to cite and to reference, I am under equipped for that argument.
Such is life.
Nick, no, even in this day and age, everything isn't literally at anyone's fingertips, and sometimes, stuff is completely unavailable for review...
were to guess why no t4 personnel were chosen to perform gassing that had experience with gassing, it would be because THERE WERE NONE.
I have not seen the complete original trial transcripts for this (the Eastern European stuff is generally harder to find). But the site below has a large collection of statements from the early trials in Poland. I haven't looked specifically for Chelmno, but go ahead and see what you find. I would gather witness names from secondary sources and then search for the actual texts on here. https://www.zapisyterroru.pl/dlibra
As for the later West German trials, they have put the Frankfurt Auschwitz trial materials online, but as far as I know this is not the case with the Chelmno trials. https://www.auschwitz-prozess.de/
For the main secondary sources, there is HH#23 on Chelmno. And for the orthodox side, the main book is Chelmno and the Holocaust by Patrick Montague.
