Born in Breslau in 1884, Wietersheim attended a Kadettenanstalt and began his military career in 1902. From 1903 until the end of World War I, Wietersheim continued to serve in the army and was awarded the Iron Cross, 1st and 2nd Class. After the war, Wietersheim had two simultaneous General Staff assignments as a captain in the staff of the 3rd Division, and also the general staff of the XXV Reserve Corps. He was promoted to major and was made an Abteilungsleiter, or department manager, at the Reich Defense Ministry, the governmental organ that determined the overarching policy of the Reichswehr in relation to the Weimar Republic. During the early 1930s, Wietersheim served as the Chief of Staff of the 3rd Division and continued his work with the Defense Ministry. He was promoted to Oberst in November 1932 and to Generalmajor in July 1934. When the Defense Ministry was reorganized as the War Ministry under Adolf Hitler, chancellor of Germany and dictator since 1933, in 1935 to match Hitler's simultaneous dissolution of the Reichswehr and creation of the greatly expanded, war-oriented Wehrmacht, Wietersheim was made the Oberquartiermeister I of the General Staff. This position, "immediately subordinated to the Chief of the General Staff," entailed the control of several departments of General Staff, "carrying command of the operations, transport and supply sections." As the General Staff was put on a war footing, this high-level logistics command was a "key position," and Wietersheim, "a brilliant Generalmajor", held this role from March 1935 until later-Field Marshal Erich von Manstein, at that time junior to Wietersheim, took over for him in October 1936. During this time, Wietersheim had been promoted to Generalleutnant, and, after handing over his post as O. Qu. I to Manstein, he took over command of the 29th Infantry Division on 1 October 1936 his first real position outside the internal command structure of the General Staff. On 1 February 1938, Wietersheim was promoted to General der Infanterie, and was given command of XIV Motorised Corps, later renamed to XIV Panzer Corps, on 1 April 1938, upon the formation of this unit. On 10 August 1938, Wietersheim had been called to the Berghof, Hitler's Bavarian retreat, along with a group of other high-ranking Wehrmacht chiefs of staff in order that Hitler could attempt to persuade them that invading Czechoslovakia was a good plan of action. Most of the generals were not convinced by Hitler's arguments, but Generals Jodl and Manstein later commented that Wietersheim, who was the highest-ranking officer in attendance, was the only one present to argue with Hitler directly about the faults in his plan, namely that an invasion of Czechoslovakia would leave the West Wall along the German-French border weak and in risk of being overrun within a few weeks should a French force decide to attack. Jodl reported in his diary that Hitler "became furious" and yelled at Wietersheim: "I say to you Herr General... will be held not only for three weeks but for three years!"
World War II
Wietersheim's XIV Motorised Corps participated in the Invasion of Poland in 1939, where it fought in the Battle of Radom and the Siege of Warsaw, as well as in the Battle of Kock. The corps later took part in the Battle of France in 1940 as the Wehrmacht drove from the Ardennes to the English Channel. In June 1941, the unit under Wietersheim participated in Operation Barbarossa, where, as part of the First Panzer Group, it served with Army Group South on the southern sector of the eastern front, advancing via Lvov, Tarnopol and Zhitomir to Kremenchug and Mirgorod, and south to Marfinskaya in the Mius sector. The corps spearheaded First Panzer Group's difficult and impressive drive to Kiev during the Battle of Kiev, and participated in the Battle of Rostov. Early in the Battle of Stalingrad, Wietersheim used his tanks to protect the advance from the Don River to the Volga, which was criticized for being an inappropriate use of an armored formation. Soon after, having encountered exceptionally strong resistance from Red Army troops, he suggested a partial withdrawal to the Don, due to high casualties among his troops in the salient north of Stalingrad, just to the west of the Volga. Deemed acts of incompetence and defeatism, he was relieved of command by the head of the German Sixth Army, Friedrich Paulus, and subsequently dismissed by Hitler. Historian Alan Clark reported that Wietersheim returned to Germany after his dismissal, only reappearing in any military context in 1945 as a private in a Pomeranian Volkssturm unit.
