Charles Spicer recounts how, by September 1938, the amateur spies learned of the Oster Conspiracy, a robust plan by German military and police units to arrest Hitler and prevent war. Spicer argues this was a credible arrangement that could have succeeded had Britain supported the resistance. Instead, Chamberlain's "Plan Zed"—his personal flights to meet Hitler—undermined the conspirators by robbing them of their casus belli. Intelligence regarding this plot reached the cabinet and was referenced in minutes, but it was never acted upon. Consequently, Hitler gained the Sudetenland and vital armament works without a fight, effectively fueling his future war machine. (10)
