As the saying goes, History is written by the winners and that’s obviously true for World War II and an event as seminal as D-Day.
We found a book on Amazon called D-Day Through German Eyes and it’s not like anything we’ve ever read about June 6, 1944. Unfortunately we weren't able to post it on the 6th.
The guy who put it together didn’t write it. His grandfather did the work but died before he could finish. He was a German war correspondent and he spent a lot of time looking at the Atlantic defenses. Ten years after D-Day he tried to track down some of the soldiers that he met and recorded their reactions to the Allied Invasion.
