I’m not what the significance is of the increased mention in these articles of Soviets shifting reserves from the east and of the upcoming Russian winter.
The Soviets were able to send the “Siberian” army which faced the Japanese army in China because they had a guarantee from their spy Sorge that the Japanese would not attack. If the Japanese had attacked the Soviets in the East the war would have been lost for the Soviets. This was probably the most momentus decision in WW2. Hitler’s 2 month delay on the drive for Moscow while Kiev was taken was also just as momentus. Without the Siberian army the Soviets only had the remnants of already shattered armies/divisions to face the Wermacht at it’s pinnacle of strength.
shhhhhhhhhhhhhhh... don't tell!
The Germans don't know it, the Russians are coming, the Russians are coming... {it's a big secret!}
No body knows it, except, except...
