Regarding Model's Suicide 

 Hitler commented after Model's suicide words to the effect that, "If he can do it, so can I". That suggests some measure of the power of respect Hitler had for Model, one of the few Generals who could not be conned by Hitler's verbal abuse, and thereby gained Hitler's authentic respect 

 Model sought every rational way from suicide. It was, for him, not an issue in personal bravery, or allegiance to a government, but to an illusory military code of conduct. My own sense is that the German High Command were deeply disaffected by the surrender of von Paulus at Stalingrad. Model's comment, shortly before death, and having exhausted alternative npn-suicide options fully over two days was that "Field Marshals do not surrender." 

 In the end, Model had been conned.
