Hello Dénes. It is indeed a
huge topic.
Nil satis nisi optimum.
Sorry, I should have mentioned that I have
Stopped at Stalingrad (excellent book); and
Black Cross/Red Star vol.3 is on my wish list. I also have most of von Richthofen's diary from BA-MA (now that was a lot of typing... and a lot of it still needs translating).
I felt I should include some aerial aspects because a few readers of
Blitzkrieg Unleashed felt the Luftwaffe wasn't given enough coverage and also because some of the troops (especially those in the Caucasus) complain about lack of air cover from mid-late August 1942 onwards.
