far side. During the winter of 1940 through the spring of 1941 he commanded a panzer regiment, and led this unit during the Battle of Greece. He later commanded a panzer brigade in the same division. He returned to staff duties with the OKH in the Inspectorate of Armoured Forces in July 1941. In May 1942, Balck went to the Eastern Front in command of the 11th Panzer Division in Ukraine and southern Russia. Following the encirclement of the 6th Army at Stalingrad in the Soviet Operation Uranus, the German southern front faced a generalized collapse. Balck's division took part in the efforts to stop the Soviet advance. In battles along the Chir River his division destroyed an entire Soviet Tank Corps and much of the Soviet 5th Tank Army. For this and other achievements Balck was made one of only twenty-seven officers in the entire war who received the Knight's Cross with Oak Leaves, Swords, and Diamonds. Balck was then given command of the Heer's elite unit, Großdeutschland Division which he led at Zhitomir in 1943. After a brief posting to Italy in which he commanded the XIV Panzer Corps, he returned to command the XLVIII Panzer Corps on the Eastern Front in December 1943, as well as the operations against the Soviet winter/spring offensive in western Ukraine in 1944. In July 1944 Balck commanded the Corps during the initial phase of the Soviet Lvov-Sandomierz Offensive. He was closely involved in the failed relief attempt of the encircled XIII Army Corps in the Brody pocket, where it was destroyed. In August 1944 he assumed command of the 4th Panzer Army. In September 1944 Balck was transferred from 4th Panzer Army in Poland to the Western Front to command Army Group G in relief of General Johannes Blaskowitz in the Alsace region of France. Balck was unable to stop the Allied advance under General George S. Patton, and in late December he was relieved of command of Army Group G and placed in the officer reserve pool. By the intervention of General Heinz Guderian he was transferred to command the reconstituted 6th Army in Hungary, which also had operational control of two Hungarian armies. Balck's unit surrendered to the U.S. XX Corps in Austria on 8 May 1945. Postwar life Balck was a POW and remained in captivity until 1947. He declined to participate in the US Army Historical Division's
