There was a Great YouTube channel of WWII broadcasts that got removed because they included broadcasts of Hitler’s speeches.
If you are into WWII history, YouTube has English subtitled copies of WWII German newsreels. Look for “die deutsche wochenschau english subtitles”.
It is interesting to watch the tone of the series as the war progresses. In 1940 it’s all “Our soldiers are saving Norway and Denmark from English invasion”. By 1944, it is more like “Our brave lads are repositioning to more defensible lines” i.e. retreating. In early 1945 it’s “You’ll find taking Aachen a lot tougher than Paris or Bucharest”. They never say they are losing, but I’m sure their audience had no illusions.
