In August 1938, Beck suggested to Brauchitsch that a "house cleaning" of the Nazi regime was necessary, under which the influence of the SS would be reduced, but Hitler would continue as dictator. At a 10 August summit, the leading generals of the "Reich", Hitler spent much of the time attacking Beck's arguments against "Fall Grün" and won over the majority of the generals. Beck resigned alone on 18 August. He was replaced, as head of the General Staff, by General Franz Halder. At Hitler's request, Beck kept his resignation secret and thus nullified the protest value of his resignation. Hitler promised Beck that if he kept his resignation secret, he would be rewarded with a major field command, and Beck was much disillusioned after he was instead put on the retired list.
