As stated by Rommel's son Manfred, his own superiors at the base near his home had already been executed and he was allowed to return home. Shortly after breakfast, his father received a call announcing that a car was on its way. Rommel said, "'So today will decide what is planned for me; whether a People's Court or a new command in the East.' After meeting with the visitors Rommel announced to his family that he would be dead within minutes. He was supplied with poison and committed suicide. If he had not done so, his family would have been executed.
