Remember this moment. If we don't convince the field marshal (Fedor von Bock) to fly to Hitler at once and have these orders (Commissar Order) canceled, the German people will be burdened with a guilt the world will not forget in a hundred years. This guilt will fall not only on Hitler, Himmler, Göring, and their comrades but on you and me, your wife and mine, your children and mine, that woman crossing the street, and those children over there playing ball.
