Tomasz Kamusella cites estimates of 7 million expelled during both "wild" and "legal" expulsions from the Recovered Territories (Deutsche Ostgebiete) until 1948.
According to Kacowicz, about 3.5 million people had fled before the organized expulsions began, mainly driven by fear of the advancing Soviet Army, between seven hundred and eight hundred thousand Germans were affected by the "wild" expulsions, and another three millions were expelled in 1946 and 1947 [REF].
