On 13 October 1941 (15 October, according to other sources), the Wehrmacht resumed its offensive. At first, the German forces attempted to bypass Soviet defenses by pushing northeast towards the weakly protected city of Kalinin and south towards Kaluga and Tula, capturing all except Tula by 14 October. Encouraged by these initial successes, the Germans launched a frontal assault against the fortified line, taking Mozhaisk and Maloyaroslavets on 18 October, Naro-Fominsk on 21 October, and Volokolamsk on 27 October after intense fighting. Because of the increasing danger of flanking attacks, Zhukov was forced to fall back, withdrawing his forces east of the Nara river.Zhukov, tome 2, p. 24.
