The details of the mass atrocity are virtually complete...gas chambers and killing of tiny children and all other Jews on an industrial scale.
Somehow, the story I remember during my education was that the “full extent of this extermination was not known” until some camps were liberated by Americans in the Spring of 1945. This is obviously not true.
I feel like i have been lied to my whole life. We did know about the Jews being killed during the process. I was NOT a surprise at the end of the war as I have always understood it.
