If Army Group North were successfully able to drive to Leningrad by the end of July and take the city by coup de main, would the resulting disruption of Soviet forces and freeing up of German armor for operations against Moscow, plus of course opening up Leningrad as a supply hub, have resulted in the fall of Moscow in December?
Manstein's corps languished on the Dvina for a week without action, which allowed Soviet defenses to get organized and dramatically hinder the advance beyond the river; had he exploited immediately with the XLI Panzer corps following upon resolving their armor battle, rather than heading to Jakobstadt and attempting to cross the river there. Assuming that does happen and result in the quick capture of Pskov and collapse of Soviet CiC in the Baltic area as a result and that results in the capture of Leningrad by the end of July, what does that mean for Moscow when Typhoon starts?
