there are so many first-hand accounts of the terrible sufferings of the holocaust, I cannot really see why dc need to read a fictional non very realistic story about it in class. Perhaps the other books, of which there are so many, have details that primary school dc could not cope with? Boy in the striped.. does not detail what happens at the camp, does it? In the film they go inot the room, the door is closed and the lights go out.
In terms of what people may or may not have known, I think we will never get an answer to that. When I taught English to my group of old fogies in Berlin, they told me differing accounts but along the lines that they knew whatever was happening to the Jews in the East was not good (since what was happening to them in Germany itself was already drastic) but they did not know exactly what was happening; and I had an old man born 1934 in my class who said anyone born when he was or before knew everything essentially and not to believe them if they told me otherwise. So who knows?
Have just read a book by a Jewish man who spent the war years in one of those Adolf Hitler elite schools were they trimmed the future SS leadership. It is quite a remarkable book/story since he was really in the lion's den. He was arrested by the German army in the East somewhere and told them when they asked if he was Jewish that he was an ethnic German which they believed, they took him in as a kind of mascot to the front and later he was sent to Germany and to this school by an army officer who planned to adopt him. And it is a true story despite sounding quite incredible.
It is not a book appropriate for primary since he discusses trying to stretch his foreskin so as not to be detected in the showers and mentions though does not detail sex in a train carriage, couple of episodes like that. I think it is a good book for KS3 and has been made into a film which I have not seen.
The book doesn't discuss the details of the holocaust and what is interesting is that the author says that he had not heard about the holocaust at this school despite having an obvious interest in knowing what the fate of the Jews was.Having escaped a mass shooting by the skin of his teeth , he had an idea but had not heard it seems about the gas chambers in the camps. He does go to Lodz where his family are trapped in the ghetto and travels through on the bus in his Hitler youth uniform hoping to catch sight of his parents who by then ar probably already dead.
