Is he really using the best strategy for blizzard defense. He had all those units digging for several turns and it looks as though you will punch through that line in no time.
He clearly got his fort levels squashed in many cases when the bug quadrupled the rate decay, so that helped my cause. Even though it got fixed, that in combination with airfields no longer preventing fort decay means a generally weaker line. That said, since the line runs southeast to northwest, I am am able to get up to that winter line quickest in the south, and longest in the north. In fact he has so much ground to give farther north, it will likely mean I reach it in the last weeks of blizzard, when he'll get ready to start moving the other way.
The original game plan was to get 4 mobile armies through the line north of Stalino, but I modified that somewhat because of the time it takes to punch through and meantime these mobile armies sit idle. So I've shifted cavalry corps north to take on some of the more vulnerable units which are in the open. Meanwhile the new plan is to have the Causasus Front which is starting to get on line, eat away at the line to the far south.
I'm quite content with the fact there was no fight for Moscow. Clearly Pelton sees his mission accomplished there, having trashed the manpower. But as Flaviusx says, time will heal that wound. And the more Pelton withdraws west, the more distance between him and Moscow. I strongly suspect he'll make no attempt to retake it going forward. For him, it's a numbers game and he has been able to reduce the Soviet manpower numbers going into '42.
