Political map of Europe & the Mediterranean 19 March 1943 (Aftermath of Stalingrad): By February it was all over for the Sixth Army at Stalingrad (Battle of Stalingrad) as the Soviet offensive gathered momentum along much of the Eastern Front (Eastern Front (World War II)). However the rapid advance left the Russians overextended, allowing Germany to regroup and launch a punishing counterattack in the Ukraine (Third Battle of Kharkov).
