I think the incident with Winston Churchill was in 1931 or thereabouts—definitely before WWII. George Will, I think it was, mentioned it in a column, reflecting on how different history might have been without Churchill as Prime Minister during WWII (if he had been killed).
Thanks for the information. I read about the incident in a biography written by Churchill’s bodyguard, but I can’t recall the book’s name. I read it at 9 or 10, nearly 50 years ago, so I’m not surprised that I remembered the details wrong.
