reminded me of this German newsreel from June 1944, after Normandy landings, 17 minutes long, with English subtitles: https://www.youtube.com/watch?v=q0M1Uvh_uvE

The only questionable statement is how German army was ready, but even this can be explained away, they did shoot back. Everything else sounds true or at least plausible. Shot down an aircraft, destroyed a few tanks, captured a few soldiers? Guess they did. True but totally irrelevant, no information value. Yet it manages to create a feeling of "we are winning", without telling it directly. Especially if you want to believe it.
