Editing 20 July plot (section)

=== Aborted attempts ===
The plot was now fully prepared.{{Citation needed|date=July 2023}} On 7 July 1944 General [[Helmuth Stieff]] was to kill Hitler at a display of new uniforms at [[Schloss Klessheim|Klessheim castle]] near [[Salzburg]].{{Citation needed|date=July 2023}} However, Stieff felt unable to kill Hitler. Stauffenberg now decided to do both, assassinate Hitler and to manage the plot in Berlin.{{Citation needed|date=July 2023}}

On 14 July Stauffenberg attended Hitler's conferences carrying a bomb in his briefcase, but because the conspirators had decided that [[Heinrich Himmler]] and [[Hermann Göring]] should be killed simultaneously if the planned mobilisation of Operation Valkyrie was to have a chance to succeed, he held back at the last minute because Himmler was not present. In fact, it was unusual for Himmler to attend military conferences.{{sfn|Kurtz|1946|p=226}}

By 15 July, when Stauffenberg again flew to the {{lang|de|Wolfsschanze}}, this condition had been dropped.{{Citation needed|date=July 2023}} The plan was for Stauffenberg to plant the briefcase with the bomb in Hitler's conference room with a timer running, excuse himself from the meeting, wait for the explosion, then fly back to Berlin and join the other plotters at the [[Bendlerblock]].{{Citation needed|date=July 2023}} Operation Valkyrie would be mobilised, the Reserve Army would take control of Germany and the other Nazi leaders would be arrested.{{Citation needed|date=July 2023}} Beck would be appointed provisional head of state, Goerdeler would be chancellor, and Witzleben would be commander-in-chief of the armed forces.{{Citation needed|date=July 2023}}

Again on 15 July, the attempt was called off at the last minute. Himmler and Göring were present, but Hitler was called out of the room at the last moment. Stauffenberg was able to intercept the bomb and prevent its discovery.{{sfn|Kurtz|1946|p=226}}
