At the trial before the Volksgerichtshof on February 1, 1945 it was not possible to prove that he had known about the assassination plans, but he was sentenced to two years’ imprisonment for defeatist statements made during a tea party in August 1943, whereby his age and failing health mitigated the punishment.
Under retssagen i Volksgerichtshof den 1. februar 1945 kunne man ikke bevise, at han var medvidende om attentatplanerne, men han blev alligevel idømt to års fængsel for defaitistiske ytringer under et teselskab i august 1943, hvorved hans alder og hans dårlige helbred blev inddraget som formildende omstændigheder ved strafudmålingen.
