My father came home to convalesce, and from the very beginning the Gestapo was in front of our house. On Oct. 14, two generals [came] to the house [and] asked to speak to my father alone. My father came upstairs and said to my mother: “I will be dead in 20 minutes. They told me I participated in the plot. They told me that they would give me the chance to die from poison. If I take the poison, the usual measures will not be taken against the family. This is the best arrangement I can get.” He was really calm and self-controlled.

My mother was very shocked, and my father left her saying almost nothing. He looked at me for maybe half a minute but said nothing. He shook my hand.

Of course the doctors knew that he had died from poison, but they testified that he died from a stroke. There was a large state funeral in Ulm. There was [even] a wreath from Hitler.
