Operation Uranus: Operation "Uranus" (Russian: Опера́ция «Ура́н», romanised: "Operatsiya "Uran"" ) was the codename of the Soviet 19–23 November 1942 strategic operation in World War II which led to the encirclement of the German Sixth Army, the Third and Fourth Romanian armies, and portions of the German Fourth Panzer Army.  The operation formed part of the ongoing Battle of Stalingrad, and was aimed at destroying German forces in and around Stalingrad.  Planning for Operation "Uranus" had commenced in September 1942, and was developed simultaneously with plans to envelop and destroy German Army Group Center and German forces in the Caucasus.  The Red Army took advantage of the German army's poor preparation for winter, and the fact that its forces in the southern Soviet Union were overstretched near Stalingrad, using weaker Romanian troops to guard their flanks; the offensives' starting points were established along the section of the front directly opposite Romanian forces.  These Axis armies lacked heavy equipment to deal with Soviet armor.
