1943? D-Day wasn’t until June 1944. Was Germany’s defeat that obvious that early?
As for autobiographical or semi-autobiographical accounts, the one (of the many) which I found particularly moving was by Primo Levi in a book called The Periodic Table - mainly because only one or two chapters (or rather episodes) dealt with the camps themselves. In essence, the book is about this man (a professional chemist) and his love of chemistry - being sent to the camps was only one episode (albeit a devistating one) in his eventful life.
The part I found most interesting was an account of how, working after the war as a chemistry consultant for a big firm, he found himself involved in a commercial dispute with a German supplier over a problem with an ingredient. Gradually, through official correspondence, he realizes that his (unseen) opposite number at the German firm was the same man who supervised the lab he worked in when he was a slave at the Chemical factory attached to the death camp he was interned in… a very moving exchange ensues, which really brings home the everyday reality of the situation.
