For my German attack, I decided that my concentration should be in the south. The southern edge is the only place on the map where the Germans can attack from two sides. It's also the furthest point from the majority of Russian reinforcements. Logic=Awesome.
The caveat is this: setup restrictions for this scenario force you to be widely spread out at start. The real decisions are about where to place your big weapons. I place both my HMGs, and two of my three flamethrowers in the southern third of the map area.
My thought in the north was just make some effort, and hope to get lucky. A successful attack along the north edge (i.e., capturing building W1) could be a spectacular development, as it would greatly threaten the Russian reinforcements. Losing ground there would be devastating for the Russians.
Trouble is, I knew from experience that attacking in the shadow of Pavlov's house was more than a little difficult. Jim had the proper precautions taken, with wire, mines, a MMG, and a 45L covering the German axis of advance. I managed early on to breach a fortified location of the flour mill, and get a squad in the building.
That would be the high water mark of the attack in the north. Eventually, the well placed Russian weapons and relative lack of cover would wear the German force down.
In the middle, I wanted to have just enough of a threat to make the Russians play an honest defense. As the game moved along, I hedged on this strategy. I kept the middle elements largely in place, when I would have been better off moving 2-3 squads further south to participate in the main thrust.
