I suppose, the success of Westerwald will to a large degree neutralize the threat of a thrust from the Tula area...

Do you think you are exploiting game mechanics, or is it still a freewheeling strategic exercise for you where you were in part lucky, but apparently also learned lessons about supply management? You mentioned in the beginning of this thread that after three or four attempts at it you felt that you grasped how to balance maneuver and resupply, so I'm wondering if we're seeing here a master of the "game rules" at work, or sheer genius (with a bit of a benefit of hindsight, given that the Wehrmacht was a bit surprised about mud and winter conditions and just how many tanks the Russians had and how vast the country's expanse actually was; you clearly know a bit about the conditions that await you even though you can't predict when exactly the weather changes etc.)
