When Germany invaded the USSR, it went for 3 main objectives (Moscow, Leningrad, Stalingrad), correct?
I can think of a few reasons for those objectives. Are there others aside from the ones I list? Are some of those reasons false or exaggerated?
Leningrad: Propaganda victory mainly because of the name. Capturing Leningrad made it easier to ship through the Baltic sea, simplifying logistics.
Moscow: Propaganda victory because it’s the capital. The Soviet state under Stalin must have been extremely centralized so this would have amounted to cutting off the snake’s head, throwing the rest of the USSR into confusion.
Stalingrad: Propaganda victory because of the name. Gave access to the Caucasus and its oil resources.
In the end, Germany captured none of them. What would have happened if it had?
Blitzkrieg had been about concentrating forces in a few spots and penetrating deeply. Why split forces to attack 3 distant objectives simultaneously rather than concentrating on taking them one by one? Is there a reason to think that would have succeeded?
