Very good documentary, but it is sometimes very hard to understand for a non-english speaker, especially the german men who are forced to speak english with a bad pronunciation. And the automatic subtitles are often wrong... It would be good to have the english text of all what is said in this film.
As said at the end of this film, it is very probable that if Dönitz has had the number of U- boats (or U-Boote) he was asking for at the beginning of the war, Great-Britain would have been forced to stop this silly war against Germany.
