And if I was in his shoes, coming off the Eastern front I'd have probably swam the Channel at the first chance considering Hitler's leadership and what he had done to Germany. In June '44 Severloh knew Stalin had over 1,200 divisions crossing into Poland versus the few dozen (actual) German divisions. The only thing slowing the Red Army down was the supply lines.
The Normandy Wehrmacht divisions had many E front re-assignees like Severloh so it was well known there was no way in Hell the Red Army could be stopped. They were not patriots they were ideologues who were committed to fascism and so they fought on. Imo they should all have died with Hitler, particularly the 'patriotic' zealots. The POW camps in France did a good job of it after the war where over a million German POWs met their end in a similar fashion to what Germany did to millions of Russian POWs 4 years earlier.
Your heart is full of rancor. I pity you.
