I was shocked to learn, from a comment made by a reader of my blog, that Wikipedia does not mention the gas chamber at Dachau. I couldn’t believe it. I had to check it out for myself, and sure enough, there is no mention of any gas chambers, of any kind at Dachau, on the Wikipedia page.
But don’t get the idea that you can now deny the Dachau gas chamber, just because Wikipedia doesn’t mention it.
The Dachau homicidal gas chamber (in the shower room) and the 4 disinfection gas chambers are still there; you will go to prison for 5 years if you deny this. Don’t count on using Wikipedia in your defense at your Holocaust denial trial. There is no defense against Holocaust denial, which is now against the law in 19 countries.
When American troops liberated Dachau, they found a homicidal gas chamber, which was disguised as a shower room. I wrote about this on my website at http://www.scrapbookpages.com/DachauScrapbook/GasChamber/history02.html
Now, after all these years, Wikipedia is denying the Dachau gas chamber.
However, I did learn this on the Dachau Wikipedia page:
On 14 April 1945, Himmler ordered the evacuation of the camp and the extermination of all inmates at Dachau, writing, “No prisoners shall be allowed to fall into the hands of the enemy alive.” Approximately 10,000 of the 30,000 prisoners were sick at the time of liberation. 
If you click on  on the Wikipedia page, you will see this:
Slaying of All at Dachau Was Ordered by Nazis. New York Times 7 May 1945. pg. 5
So now we are supposed to believe the New York Times article which says that Heinrich Himmler ordered all the Dachau prisoners to be killed? Sorry, but I need a better source than the New York Times, aka “the Jew York Times”.
I studied the alleged story that Himmler gave an order to kill all the Dachau prisoners extensively, and blogged about it on this blog post: https://furtherglory.wordpress.com/2010/10/21/did-himmler-really-order-all-the-prisoners-at-dachau-to-be-killed/
I previously blogged about the lack of any mention of the Dachau gas chamber on Wikipedia at https://furtherglory.wordpress.com/2015/01/16/wikipedia-does-not-mention-the-gas-chambers-at-dachau/
