I just read a book that I picked up from my personal library and that I haven't read in almost 20 years. The book is called "The legion of the damned"(I think that would be the English transl.) and is written by the Danish and much debated author Sven Hazel.
Now I know there are patrons here that know heaps more about the Second World War than I do, so my question is:

Did Germany during WWII have a resistance organisation? (A claim by the author).

Another claim of the author was that the SS was greatly despised by the rest of the Wehrmacht, so greatly despised that they didn't dear to move in front of regular Wehrmacht companies during frontline battles as they would be shot at by their own as well as by the opposing forces. One claim he made was that battle between regular Wehrmacht soldiers and Russian soldiers would make a halt if a SS company made an appearance. The Russians and the Wehrmacht soldiers would suddenly be on the same side and both battle the SS. when the SS was destroyed the battle continued between the Wehrmarcht and the Russian soldiers as if nothing had happened.

Was this so or is this just some claim from one who wants to redeem himself from fighting on the wrong side?
