This is an AI enhanced version of what I think is the first of the German weekly newsreels after the invasion. The subtitles aren't perfect but you can basically follow the action. Be warned that there will be the usual Nazi racial and cultural denigration.
The Wehrmacht look invincible and the Red Army (always referred to as Bolsheviks - this was an ideological struggle) are a hapless rabble. I can't see how this could end badly for Germany at all
