[5] On 16 August, he was named as head of the Politisches Amt (Political Office) of the Supreme SA leadership in Berlin, and was primarily responsible for foreign policy issues.

He was also appointed Sonderkommissar der Obersten SA-Führung für Preußen (Special Commissioner for Prussia of the Supreme SA Leadership).
