Why do you think he was not able to write a book about Dresden?

Im my opinion, the memories of Dresden were simply too difficult to process.... too difficult to relive, and too difficult to put into words.

When I got home from the Second World War twenty-three years ago, I thought it would be easy for me to write about the destruction of Dresden, since all I would have to do would be to report what I had seen. And I thought, too, that it would be a masterpiece or at least make me a lot of money, since the subject was so big. But not many words about Dresden came from my mind then-not enough of them to make a book, anyway. And not many words come now, either, when I have become an old fart with his memories and his Pall Malls, with his sons full grown. I think of how useless the Dresden-part of my memory has been, and yet how tempting Dresden has been to write about....
