Schlacht von Rschew
As the speed of the German advance slowed and the VVS began reasserting itself, the Soviets launched a major operation which became the Battles of Rzhev. In particular, Zhigarev presided over the Vyazma airborne operation, a major operation conducted by the 4th Airborne Corps which was intended to cut off German supply and communication lines. However, the operation was not a success, and airborne elements were eliminated by German forces in Operation Hannover. As a result, Zhigarev's stint as Commander of the Air Force lasted only a short time, as he was replaced in 1942 by Alexander Novikov. He then returned to serve as the Commanding Officer of the Far Eastern Front Air Forces.
