Hi,
Turn 18, right? Your frontline north of Smolensk looks rather frightening. Whatever the outcome of "Westerwald", it leaves you with a salient around Moscow. I just went through a whole blizzard season in my GC, and I know what the Soviets can do to an exposed German Army. Although I managed to grab Leningrad and Moscow by turn 17 (Soviets down to 2.6 Mio men), and with a very short frontline - I barely had enough troops to hold the line. Why are your "Westerwald"- arrows that far west ?
