key role in the Battle of Moscow when it was deployed along the main axis of the German advance along the Volokolamsk Highway that was a central junction of the bitter fighting during the German winter offensive of 1941 (Operation Typhoon), as well as the subsequent Soviet counter-attack of 1941–42. On 18 November, during the last-ditch efforts of the Wehrmacht to encircle Moscow in 1941, General Rokossovsky, his soldiers under heavy pressure from Hoepner's 4th Panzer Group, asked his immediate superior, Zhukov, if he could withdraw the 16th Army to more advantageous positions. Zhukov categorically refused. Rokossovsky went over Zhukov's head, and spoke directly to Marshal Boris Shaposhnikov, now Chief of the General Staff in Zhukov's place; reviewing the situation Shaposhnikov immediately ordered a withdrawal. Zhukov reacted at once. He revoked the order of the superior officer, and ordered Rokossovsky to hold the position. In the immediate aftermath, Rokossovsky's army was pushed aside and the 3rd and 4th Panzer Groups were able to gain strategically important positions north of Moscow, but this marked the high point of the German advance upon Moscow. Throughout Operation Typhoon, Rokossovsky's 16th army had taken the brunt of the German effort to capture Moscow. 1942: Operation Fall Blau In March 1942 Rokossovsky was badly injured by a piece of shrapnel. It was widely rumored that Valentina Serova was a mistress of Rokossovsky during this time. While it is true that Serova, working as a hospital volunteer, met Rokossovsky several times while he was recovering from his wound, it is not acknowledged they were lovers. Evidence for their close relationship was found in the accounts of frontline soldiers. Rokossovsky also had another mistress at this time, Dr. Lt. Galina Talanova, with whom he had a daughter in 1945. After two months in a Moscow hospital Rokossovsky was reunited briefly with the 16th Army. Retreat to the Don During 1942 the Wehrmacht commenced "Operation Fall Blau" and switched the axis of their offensive from Moscow and attacked southward into the eastern Ukraine towards the Don–Volga river line, Rostov, Voronezh, Stalingrad and the Caucasus beyond. There the Germans hoped to secure fresh supplies of oil to fuel their armies. Unlike the early days of 1941 the stiffening Soviet army maintained relatively good order in retreat, backing up along a defensive line along the Don river. On 13 July 1942 Rokossovsky was given his first operational level command, a
