Born in Sitzmannsdorf, Prittwitz joined the Imperial German Army in 1908 as a Fahnenjunker and was commissioned into the 3rd Uhlan Regiment the following year and later on, served as a general staff officer for the Imperial German Army. He fought in World War I and after the end of hostilities, was retained in the postwar Reichswehr. By 1933, he was a major and despite his cavalry background, was developing an interest in a career in armoured warfare. Two years later, he was given command of the 2ndPanzer Regiment, 1st Panzer Division. He participated in the Anschluss of Austria and the occupation of Sudetenland. Now in the rank of oberst in 1938, he was appointed as commander of the 2nd Panzer Brigade, which was part of the 2nd Panzer Division. On the outbreak of World War II, Prittwitz led the brigade in the invasion of Poland during which it was heavily engaged. He was promoted to generalmajor at the conclusion of the fighting in Poland. Along with the rest of the division, Prittwitz's brigade was then transferred to the west and attached to Generalleutnant Heinz Guderian's XIX Motorised Corps. When the Germans invaded France and the Low Countries, the brigade performed well at Sedan and then advanced to the coast and reached Dunkirk. It was later used in the final stages of the campaign in France, rounding up French soldiers along the Maginot Line. When the Panzerwaffe branch of the Heer expanded, Prittwitz was selected to lead the 14th Panzer Division on 1 October 1940. His new command was originally an infantry division which had only converted to armour two months previous. Based at Dresden, Prittwitz supervised the training and development of the division and in March 1941, he was given command of the 15th Panzer Division which was preparing for the campaign in North Africa. The bulk of the 15th Panzer Division had yet to arrive in Libya but Prittwitz, accompanied by some light units of the division, arrived in the country in early April. He was immediately ordered by GeneralleutnantErwin Rommel, commander of the Afrika Korps, to take command of German forces operating near Tobruk, held by a garrison made up of Australian, British, Polish and Czechoslovak units. On 10 April, Prittwitz's group was ordered by Rommel to probe the south-east defences of Tobruk. As Prittwitz personally observed the front lines, his own vehicle came under fire from the Australian 2/28th Infantry Battalion, including so-called "bush artillery" – makeshift gun crews utilising captured Italian field guns. Prittwitz was killed in this exchange. Buried at the military cemetery at Derna, he was posthumously promoted to generalleutnant with effect from 1 April 1941.
