Great atmosphere. I'm recently reading Hinze, Niepold and others again, to get more insight in what really happened during the German collapse. I think the German infantry divisions did all they could, but the odds were simply too much against them. Only a timely retreat to the Beresina and beyond, resulting in more German reserves, could have improved the situation a little, but even then the situation was pretty hopeless. A couple of Panzer divisions also could have prevented the catastrophic loss of men, but not the collapse itself.
Your maps are very good and I love your eye for detail.
