Cold war dread and the movies

I got this e-mail from Jay in St. Paul:

"I am trying to remember a movie from the 1950's. It may have been based upon a book "Call It Treason." The movie title had Morning in it. It is about a german soldier captured in WW II. He agrees to go back into Germany to obtain information as he is not sympathetic to the national socialist govt. In a touching scene he phones his father to hear his voice and then hangs up He is shot trying to cross a river to the US lines. It is B and W, many dark scenes and powerful. Can you help?"

Jay...you are so lucky I sit up watching American Movie Classics! There are so many movies that show up there and on Turner Classic Movies that are not on video or DVD. And who knows...maybe this film is on video, but I saw it on cable. It's "Decision at Dawn" directed by Anatole Litvak who also made "Sorry Wrong Number."
