On 19 November 1942, the Red Army launched Operation Uranus. The attacking Soviet units under the command of Gen. Nikolay Vatutin consisted of three armies. This included a total of 18 infantry divisions, eight tank brigades, two motorized brigades, six cavalry divisions and one anti-tank brigade. The Soviets pushed past the Romanian Third Army. The response by the "Wehrmacht" was disorganized. Bad weather prevented air attacks against the Soviets.
