the Mediterranean, rather than using them as a strategic reserve for the Eastern Front. Hitler cancelled the offensive at Kursk after only a week, in part to divert forces to Italy. Germany's extensive losses of men and tanks ensured that the victorious Soviet Red Army enjoyed the strategic initiative for the remainder of the war. The Battle of Kursk was the first time in the Second World War that a German strategic offensive was halted before it could break through enemy defences and penetrate to its strategic depths. Though the Red Army had succeeded in winter offensives previously, their counter-offensives after the German attack at Kursk were their first successful summer offensives of the war. Background 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. Since December 1942 Field Marshal Erich von Manstein had been strongly requesting "unrestricted operational freedom" to allow him to use his forces in a fluid manner. On 6 February 1943, Manstein met with Hitler at the headquarters in Rastenburg to discuss the proposals he had previously sent. He received an approval from Hitler for a counteroffensive against the Soviet forces advancing in the Donbas region. On 12 February 1943, the remaining German forces were reorganised. To the south, Army Group Don was renamed Army Group South and placed under Manstein's command. Directly to the north, Army Group B was dissolved, with its forces and areas of responsibility divided between Army Group South and Army Group Centre. Manstein inherited responsibility for the massive breach in the German lines. On 18 February, Hitler arrived at Army Group South headquarters at Zaporizhia just hours before the Soviets liberated Kharkov, and had to be hastily evacuated on the 19th.
