Drafted into the Waffen-SS? I must admit, that's a new one on me. Anyone have a reference to such a thing?
It's possible that he was requested to "volunteer", either through bribery or intimidation. Or, he could be blowing smoke up our collective skirts and was an ardent Nazi. Only he knows the truth.
The Waffen SS formations competed with the Wehrmacht for personnel. Especially after the invasion of the Soviet Union in 1941, all manpower pools were increasingly tapped to the limit. The SS first went after ethnic Germans living outside of Germany - the Volksdeutsche, and foreign volunteers living in places like Denmark, Norway, and other "Germanic" places. After 1943, they even went after non-Germans, building units including Muslim, Ukranian, Lavtian, French, Italians, Serbs, Cossacks, etc. By 1945, half of the Waffen SS were non-German citizens.
After the July 20, 1944 plot to kill Hitler failed, the Waffen SS was given even more priority on the dwindling manpower pool. Their units had first dibs on men and equipment. By this time, many of the men were "volunteers" in name only.
If you were a young man in Germany in late 1944 or early 1945, most probably you were going to end up in some unit. Whether it was the SS or not sometimes depended on which recruiting dragnet got to you first.
The Oxford Companion to World War II has a good discussion of this - see the section on the SS.
I am skeptical too that anyone was drafted into the SS. In the beginning, the SS was highly selective of its recruits. Later, they were less stringent. But I have not read anywhere that they ever drafted anyone. They were all volunteers.
I know that definity quite a lot of people were drafted into the Waffen-SS during the late war.
