Some things make you wonder though.
1) You invade Russia, you bring winter clothing. Duh! It’s Russia!
2) Your troops are surrounded in the Stalingrad pocket, all of your generals have advised a breakout. Not a very tough decision IMHO.
3) Why Russia’s two major cities, Leningrad and Moscow were not taken when they were vulnerable, also defies reason and logic.
4) Finally, when you have the native population welcoming you with open arms, seems to me you should treat them humanely instead of turning them into partisans.
Not rocket science.
Can’t disagree with any of that. I would just add, why try to conquer Stalingrad in the first place? Besides the propaganda value of conquering “Stalin City”, what was the strategic gain? Why not bypass the city itself and continue to drive toward the Caucus with its valuable oil fields? Lack of oil was a big problem for Germany late in the war. Certainly oil from the Caucus fields would have been very useful.
