Stalin also ordered a series of massive ethnic cleansing operations to remove what he and the Soviet leadership thought of as potential by subversive elements from the theatre of war. More than 390,000 ethnic Germans in the Ukraine were forcibly deported eastwards from September 1941. Altogether there were nearly one and a half million ethnic Germans in the Soviet Union. 15,000 Soviet secret policemen descended upon the Volga to begin the expulsion of the ethnic Germans living there, removing 50,000 of them already by the middle of August 1941.
