According to other sources, in summer 1945 about 800,000 Germans were still living in East Prussia. The Red Army's brutality towards civilians during the East Prussian campaign, coupled with years of Nazi propaganda regarding the Soviet Union, led many German soldiers on the Eastern Front to believe that "there could be no purpose in surviving Soviet victory". This belief motivated many German soldiers to continue fighting even though they believed that the war was lost, and this contributed to higher Soviet casualties.
