Other parts of Nazi-occupied Poland were incorporated to bordering gaus of East Prussia and Upper Silesia i.e. Zichenau (region); and Silesian voivodeship with the counties of Oświęcim, Biała respectively. After the successful invasion of France in 1940, Germany re-annexed Alsace-Lorraine. The former département of Moselle was incorporated into the Gau of Saar-Palatinate, while Bas-Rhin and Haut-Rhin became part of the Gau Baden.
