External post defense on the hotel roof. Moscow, 1941
By October 13, 1941, the Wehrmacht had arrived at the Mozhaisk defense line. Zhukov decided to concentrate his forces at four critical points: Volokolamsk, Mozhaisk, Maloyaroslavets and Kaluga. The entire Soviet Western Front, almost completely destroyed after its encirclement near Vyazma, was being recreated from scratch.
