The Reich Ministry for the Occupied Eastern Territories ordered Koch and Hinrich Lohse (the Reichskommissar of Ostland) in March 1942 to supply 380,000 farm workers and 247,000 industrial workers for German work needs. Later Koch was mentioned during the new year message of 1943, how he "recruited" 710,000 workers in Ukraine. This and subsequent "worker registration" drives in Ukraine would eventually backfire after the Battle of Kursk (July–August 1943) when the Germans would attempt to build a defensive line along the Dnieper only to discover that the necessary manpower had been either recruited to forced labour in Germany or had gone underground to forestall such "recruitment".
