At a second meeting, with trust established between two sides, Haushofer was known to tell Schulze-Boysen that an assassination attempt against Hitler was being planned.
These two meetings created a level of trust between the two men that reduced their risk of exposure when trying to turn the Wehrmacht officer.

codes that enabled the Funkabwehr and specifically Referat 12 to decipher Red Orchestra message traffic. When Heilmann discovered that the Red Orchestra traffic was being read from documents that had been illegally provided by Alfred Traxl, he conducted a search for the names of ''Kuckoff'', ''Schulze-Boysen'' and ''Harnack'' at the agency and to his horror after 2 days, he discovered that his friends had already been exposed to the Gestapo.

When Schulze-Boysen returned, he immediately phoned the number, but unfortunately, it was answered by Vauck, who was Director of Referat 12.
Vauck using the codes that Wenzel provided was able to captured and decipher over 200 radio messages that the Red Orchestra group had sent. The last message that was deciphered provided three addresses that were passed to the

When Vauck answered he was astonished that the person who was prime subject of his investigation was on the phone and realised that Heilmann was a traitor. He asked Schulze-Boysen to clarify his name to confirm it was spelt with a ''y'' or an ''i''. After the call, Vauck phoned the Gestapo and this started a process on 31 August 1942 that resulted in many people of the
Red Orchestra being arrested, including Heilmann himself who was arrested on 5 September 1942.
