 Despite Nazi propaganda presenting all of the regions annexed as possessing significant German populations that wanted reunification with Germany, the Reich's statistics of late 1939 show that only 31,000 out of 994,092 people in this territory were ethnic Germans.East Prussia was only slightly affected by the war until January 1945, when it was devastated during the East Prussian Offensive.Most of its inhabitants became refugees in bitterly cold weather during the Evacuation of East Prussia.
