Operation Little Saturn was a Red Army offensive on the Eastern Front of World War II that led to battles in Don and Chir rivers region in German-occupied Soviet Union territory in 16–30 December 1942.

Operation Uranus was the codename of the Soviet Red Army's 19–23 November 1942 strategic operation on the Eastern Front of World War II which led to the encirclement of Axis forces in the vicinity of Stalingrad: the German Sixth Army, the Third and Fourth Romanian armies, and portions of the German Fourth Panzer Army. The Red Army carried out the operation at roughly the midpoint of the five-month long Battle of Stalingrad, aiming to destroy German forces in and around Stalingrad. Planning for Operation Uranus had commenced in September 1942, and developed simultaneously with plans to envelop and destroy German Army Group Center and German forces in the Caucasus.
