@Theo202,
I posted a more comprehensive answer on Holocaust denial which has been removed, with no explanation or notification, where the Rules do not explain why, and with apparently no appeal procedure, or possibility of contacting any moderator.
Therefore I thought I might with respect, try again with a much shorter post and hope that this will be acceptable.
The following is an extract of evidence concerning the Auschwitz concentration (death) camp, but there were of course many other concentration camps. It is part of the evidence of Rudolf Hoess, Commander of the camp at Auschwitz, whose evidence describes the situation at Auschwitz up to 1 December 1943, but bear in mind that the war did not end until 1945:

I commanded Auschwitz until 1 December 1943, and estimate that at least 2,500,000 victims were executed and exterminated there by gassing and burning, and at least another half million succumbed to starvation and disease making a total dead of about 3,000,000.
