Thomas also claims that Karl Strasser was an officer of the 12th SS Armored division. The 12th SS was mostly a Hitler Youth armored division which was all but obliterated in the opening days of Operation Overlord. In August, it was incapable of being any use to an offensive so it was tasked with defending the German's retreat routes and supply lines. The 2nd SS and part of the 1st SS armored were the only SS divisions involved in Mortain. The 12th SS was later charged with war crimes for executing Canadian POWs.
Additionally, there were no U.S. artillery units in Mortain, contrary to Nelson's story.
