Richard Landwehr has been the author of numerous books about the Waffen-SS, its foreign (that is, non-German) volunteers in particular. He has been putting out a magazine called Siegrunen on that topic "[f]or more than 25 years". Landwehr's work is often quoted by neo-Nazi websites and he is routinely defended by them. The group Nazi Lauck NSDAP/AO expressed outrage after they claimed a German court had tried Landwehr in absentia for charges arising from his books.
