As the Battle of Stalingrad slowly ground to its conclusion, the Red Army moved to a general offensive in the south, in Operation Little Saturn. By January 1943, a gap had opened between German Army Group B and Army Group Don, and the advancing Soviet armies threatened to cut off all German forces south of the Don River, including Army Group A operating in the Caucasus. Army Group Center came under significant pressure as well. Kursk was retaken by the Soviets on 8 February 1943, and Rostov on 14 February. The Soviet Bryansk, Western, and newly created Central Fronts prepared for an offensive which envisioned the encirclement of Army Group Centre between Bryansk and Smolensk. By February 1943 the southern sector of the German front was in strategic crisis.
