He was implicated by Gen. Beck and Goerdler, the Mayor of Leipzig. An intermediary was also quite damning to the Field Marshal. A Dr. Strolin, whom his wife and he were friends with. They even served together in WWI.
Rommel lost all respect for Hitler after el Alamein due to the Fuhrer’s disdain for Germany’s people. He never once bought into the assassination plot, only that Hitler should be arrested and brought to trial, specifically because his order’s grew more and more incoherent.
I knew Rommel was against the assassination but favored arrest and replacement of Hitler.
I didn’t know about Strolin.
I imagine many people were singing like birds trying to save their families.
