When I was a senior in high school, I wrote a little essay in which I noted that things had gone too easily for the Western allies after the first couple of years of WWII. We often surprised them, they seldom surprised us. I’ve never seen an example of a historian saying that before 1974, when the facts about Ultra started to come out. There were people – Germans – that noticed in WWII. They figured that there was some kind of intelligence leak, but they couldn’t figure out what it was. The guys running their machine cryptography assured them that it was unbreakable.
I think that there were some historians that didn’t mention it because they knew all about it – people like Samuel Eliot Morison. But most historians didn’t have that WWII experience, weren’t read in, and they never saw it ( I’m open to correction on this).
Why the hell could I see this when they couldn’t?
