do you know more specific about this topic?
Yes, I guess you are right and for the time being it is impossible to learn something more about this if all Divisional (71. ID)and Regimental (IR 191, IR 194) records are destroyes. The chance for research in this matter is close to zero and that is really frustrating but a matter of fact.
So for conclusions: the battle of the Railway-Station in September 1942 remains a myth, a heroe symbol for the Soviet (13rd. Guards Rifle Div./39th and 42nd Regiment) and a black gap for the 71. ID.
So all the scenarios of the wargamers (e.g. Call of Duty 1) about the close-combat inside Stalingrad-1 is pure imagination?
