You are clearly unfamiliar with the concept of General Mud in that part of the world.

Ask Napoleon or Hitler about him.
I mentioned mud a couple of months ago and you would think my name is Mudd...
Even I could just see it coming, the Soviets (glaring “mistake”) launched a month, maybe 2 months too early.
I was about to post the same concept. General Mud was much worse on the Germans than General Winter.
