I had both versions and compared. There are big differences.
1) The german publisher did some changes w/o asking Mr. Hannig about it. Mr. Hannig complained about this in the interview I did with him:

2) The english version contains some thoughts about politics which are not included in the german version.
I sold my german version because I do not want to support such a publisher, who seems to falsify testimonies of people (like Hannigs book) in order to change our picture of history.
