The Kalmykian Cavalry Corps (German: Kalmücken-Kavallerie-Korps) was a unit of about 5,000 Kalmyk volunteers who chose to join the German Army in 1942 rather than remain in Kalmykia as German forces retreated before the Red Army.[1] In 1943, Stalin subsequently declared the Kalmyk population as a whole to be German collaborators and had them deported to Siberia suffering great loss of life.
