The Assassination attempt on Adolf Hitler in 1944 -- An excellent, gritty treatment from Germany, in 1956

This is a gritty, painfully realistic, detailed treatment of the assassination attempt on Adolf Hitler, in 1944, produced just 12 years later, in 1956. The environment of paranoia, desperation and hopelessness in Germany at the time of the assassination attempt is lovingly recreated, there is no question whatsover to the viewers -- contemporary Germans themselves -- why this assassination attempt was made. These were all loyal German citizens, but, they had been forced to the end of their patience, and their tolerance. https://www.youtube.com/watch?v=H8rHvP37nek
