Dear Witold,
Some information can be found on this forum: https://forum.il2sturmovik.com/topic...mnik-campaign/
and on this forum: https://forum.axishistory.com/viewtopic.php?t=79735
If you know German, there is an entry in Metapedia: https://de.metapedia.org/wiki/Platzs...omnik%E2%80%9C (well, Metapedia is quite political, so it's not always objective, but you can focus on more concrete information)
There are also some videos on YouTube, like this one:

There are more in German, for example: https://www.youtube.com/watch?v=uCgrrp9rJ9Y

Good luck!
