Is that Vonnegut?

Through the book we still are reading about Billy's life. I can't help to wonder, Is Vonnegut Billy Pilgrim? When I read this book, the narrator talks about all the bad things that happens to him.

Vonnegut at the beginning of the book has a character, which name we don't know. The only thing we know about him is that he was int he Bombing of Dresden and that he is trying to write a book about it. In the book, Billy Pilgrim also experience the bombing. I wonder is Billy that character from the first chapter, and is that charcter Vonnegut?

I decided to look for Vonnegut's biography. He was a prisoner of war which really influenced his work. He was imprisoned in Dresden, Vonnegut was chosen as a leader of the POWs, because he spoke some German. While a prisoner, he witnessed the fire bombing of Dresden in February 1945. Looking at some of the the events in his life, and then going back to Pilgrim you can really see a connection. Billy when he became a prisoner, he is ordered to move. He joined a stream of POWs marching in the road. I was able to see that there is a whole connection between the author and the main character in the book. I can't wait to see all the other thing they have in similar.
