I want to know the answer to the following question:
What other parts of East Prussia were transferred after the annexation of Zichenau?
All the background I'm provided with is that "Parts of it were transferred to other regions, e.g. Suwałki to Regierungsbezirk Gumbinnen and Soldau to Regierungsbezirk Allenstein.". Is that enough to answer the question?
