Operation Valkyrie- the attempted assassination of Adolf Hitler and overthrow of his Nazi regime by some members of the German military- failed for two main reasons:
Once Hitler recovered enough that he was able to telephone officers in Berlin, the plot ended in total failure. The Nazis retook control, and the conspirators were quickly arrested and executed. Many family, friends, and anyone else even remotely related to the conspirators were also arrested, and thousands of these people were executed.
