[NBE1942]

Yes it is the key word, I think the day of begining of "Fall Blau" was the begining of operation for "capturing" Stalingrad (28 VI 1942). The first phase to capture Voronez, nextr to Don river (Don's bend) and later towards Stalingard. For me this is the period of begining the battle + phases. So it was the first pahse battle for Stalingard of capturing in Novyj Oskol railway stattion a few Hurricanes (2 at least) by German + Hungarian troops + 1 LaGG-3 more. Planes were damaged after belly landing.

I see. The battle of Moscow started on June 22, 1941, am I right???
