Russian-Germans were not the only nationality called up into the labor army to work in Karlag. In February 1942, the Soviet government began the conscription of Russian-Koreans into labor army detachments. From Kazakhstan alone they mobilized some 20,000 Russian-Korean men (64). A recorded 2,141 of these men worked in the mines at Karaganda from 1942 to 1945 (63). Other Russian-Korean labor army conscripts worked in mines, construction projects, and tree felling throughout Uzbekistan and Russia (pp. 65-66). To date comparatively little research has been done on the subject of non-German nationalities conscripted into the labor army.
