From the description:
As September 1941 begins on the Eastern Front, the war enters a new and brutal phase.
The late summer rains arrive, slowing down operations but not halting the relentless fighting.
In the north, Army Group North continues its push against Leningrad, severing the last land and rail connections and forcing the city into a deadly siege that will define the coming months.
Meanwhile, in the center, Field Marshal von Bock struggles to hold the Yelna salient as Zhukov launches one of the Red Army’s first successful counteroffensives, liberating Yelna at enormous cost. Hitler issues War Directive No. 35, signaling the renewed drive toward Moscow even as the front strains under attrition.
To the south, Guderian’s daring drive threatens Kyiv, but overstretched flanks and Eremenko’s ill-coordinated counterattacks expose the risks of the operation. Rundstedt’s armies battle to expand bridgeheads across the Dnipro, suffering heavy losses at Dnepropetrovsk. The rains, mud, and mounting casualties begin to slow the once lightning-fast blitzkrieg, foreshadowing the grinding attrition to come.
