As word of the massacres got out, many Jews fled; in Ukraine, 70 to 90 per cent of the Jews ran away. This was seen by the leader of "Einsatzkommando" VI as beneficial, as it would save the regime the costs of deporting the victims further east over the Urals. In other areas the invasion was so successful that the "Einsatzgruppen" had insufficient forces to immediately kill all the Jews in the conquered territories. A situation report from "Einsatzgruppe" C in September 1941 noted that not all Jews were members of the Bolshevist apparatus, and suggested that the total elimination of Jewry would have a negative impact on the economy and the food supply. The Nazis began to round their victims up into concentration camps and ghettos and rural districts were for the most part rendered "Judenfrei" (free of Jews). Jewish councils were set up in major cities and forced labour gangs were established to make use of the Jews as slave labour until they were totally eliminated, a goal that was postponed until 1942.
