Bomb attempt against Hitler
When Colonel Count Claus Schenk von Stauffenberg carried out a bomb attempt against Hitler’s life on July 20th, 1944, it was first supposed that it had been a time bomb left by the workers of the Todt Organization  who had been renovating the bunkers in the period just before.
In the following hours, von Stauffenberg was not a suspect. Arthur Adam's telephone hall was next to the vestibule where Stauffenberg had left his cap and his belt.
At this time, the Chief Telephonist Arthur Adam who saw Stauffenberg running away from the HQ, leaving his belongings behind did not know what to do. He walked about the site of the explosion. It was not his duty to take part in the investigation, however, he wanted to tell the investigators what he saw.
He systematically tried to approach various army officers to report that he saw the suspicious Stauffenberg escapade. However, he was often called to attention and reminded not to raise suspicion against such a highly reputed colonel.
Adam did not give up his detective role and came to see Hitler’s personal adjutant Heinz Linge to inform him that Colonel von Stauffenberg came out of the conference room and went straight into a car out of the HQ.
Adam tells Bormann that he is sure that Stauffenberg must have committed the attempt against the Führer's life, as he saw the colonel leaving the conference in a hurry without his cap, his valise and his belt. Bormann does not hesitate for a moment and takes Adam directly before Hitler. When Hitler heard Adam's testimony, he is supposed to have declared: “Stauffenberg is the perpetrator of the attack! Arrest him immediately!”
He is described to be the chief intelligence officer in the Chancellery of the Reich on April 26, 1945.
