I can understand and appreciate what you say but as it stands yours is a hypothesis With genuine respect it doesn t provide any evidence to contradict von Rintelen s account and he was after all a primary source whose account was publicly endorsed by the head or close to it of the British secret service and one of his deputies Now I can understand that Hall might have been wilfully deceiving von Rintelen however there is no evidence that this is the case nor does Hall seem to have immediately apparent motive of hostility towards his former adversary In fact strange to say there is primary evidence that after the war Admiral Hall and von Rintelen were the complete opposite of enemies but close and mutually trusting family friends Have a look at this Interesting no
