After the National Socialist seizure of power, the KGRNS and its subsidiary organizations were banned in February 1933, and Buchrucker was temporarily in custody.  The information on Buchrucker's further life is fragmentary: In connection with the Röhm murders , a political cleansing operation in the course of which Adolf Hitler and other National Socialist leaders had their actual or alleged rivals in their own ranks as well as other unpleasant people sometimes violently eliminated , Buchrucker was arrested, but later released at Hermann Göring's instigation and reactivated for the Wehrmacht.  Shortly after the outbreak of the Second World War Buchrucker is said to have been retired from the Wehrmacht with the rank of lieutenant colonel.  In his 1953 publication "Die Ehre des Soldiers. German soldiers in the European armed forces?" Buchrucker claims to have rejected Hitler as a criminal but, according to Emil Julius Gumbel, does not take a clear position on the officers' conflicts of conscience of July 20, 1944.
