In the first days of August 1944, Adolf Hitler receives Wachtmeister Arthur Adam. Following the assassination attempt of 20 July 1944 he was the first to become suspicious of Oberst Claus Schenk Graf von Stauffenberg. It was he who noticed that the colonel left the conference early and had forgotten his briefcase and service cap in the outer office. After a vain attempt to report this to the two responsible intelligence officers, he turned directly to Reichsleiter Martin Bormann who took him to Hitler in order to state his suspicions. For his deeds, Wachtmeister Arthur Adam was promoted to Oberwachtmeister and received a small house near Berlin and 20,000 RM (Reichsmark).
