On active service again in World War II, Pannwitz was awarded "bars" to his previous decorations and in September 1941 was awarded the
Knight's Cross of the Iron Cross. He received the Oak Leaves as an
Oberst (colonel) a year later for successful military leadership, when he was in command of a battle group covering the southern flank in the
battle of Stalingrad. In late November 1942, during the arrival of fresh troops of the
6th Panzer Division by train at
Kotelnikovo, hidden Soviet artillery began shelling the railway station. Pannwitz happened to be at a tank repair workshop on the edge of the town. Realising the danger, he co-opted the maintenance crews as drivers and gunners, and with six battle-worthy panzers attacked the Soviet batteries from the rear. The Soviet guns were destroyed with many casualties, with no losses to the German makeshift tank platoon who all received decorations. Pannwitz was instrumental in establishing a
Cossack force, the Cossack Cavalry Brigade, which was formed on 21 April 1943 and soon merged into
1st Cossack Cavalry Division under his command. The unit conducted anti-partisan operations in
Ukraine and
Belarus, and was then moved to fight against
Yugoslav partisans. During punitive operations in Serbia and Croatia, the Cossack regiments under Pannwitz's command committed a number of atrocities against the civilian population including several mass rapes and routine
summary executions. Even for von Pannwitz these atrocities exceeded what he perceived as normal. Moreover, in his eyes they threatened discipline and military success. Therefore he issued an order dated 20 October 1943, according to which crimes of that kind would result in the death penalty. At the ceremony in Berlin in which Pannwitz received the "Oak Leaves" for his Knight's Cross on 15 January 1943, he told Hitler that the official Nazi policies which caused Slavs to be regarded as subhumans (Untermenschen) for strategic reasons were totally wrong. During the summer of 1944, the two brigades were upgraded to become the
1st Cossack Division and 2nd Cossack Cavalry Division. On 25 February 1945 these divisions were combined to become
XV SS Cossack Cavalry Corps. Due to the respect he showed for his troops and his tendency to attend
Russian Orthodox services with them, Pannwitz was very popular with his Cossack troops. Before the end of the war, he was elected
Feldataman (German rendering of Supreme
Ataman, the highest rank in the Cossack hierarchy and one that was traditionally reserved for the
Tsar alone). By the end of the war, the SS took control of all foreign units within the German forces. The Himmler file in the Imperial War Museum contains a record of a conversation which occurred on 26 August 1944 between Himmler, Pannwitz, and his chief of staff, Colonel H.-J. von Schultz. An agreement was reached that the Cossack division, soon to be the Cossack Corps, was placed under SS administration in terms of replacements and supplies. Both the German cadre and the Cossack troops were to retain their uniforms and their
Wehrmacht or Cossack ranks. For the moment, Pannwitz refused to enter the SS, arguing: “I have been in the army since I was fifteen. To leave it now would seem to me like desertion.” Himmler sought to place all Cossack fighting units under von Pannwitz's command. Thus, in November 1944, most units were transferred to the Waffen-SS and integrated into the newly formed
XV SS Cossack Cavalry Corps. By his own request von Pannwitz was discharged from the army on 10 February 1945 and entered the SS in the rank of SS-Gruppenführer and lieutenant-general of the Waffen-SS the following day. ==Aftermath==
