- The story that the English deliberately allowed Coventry to be bombed for
- fear the Germans would learn that Enigma had been compromised is one that
- is highly arguable, and is not considered true by at least one expert in
- the field. In his book "Kahn on Codes" crypto historian David Kahn says
- (now here it gets approximate, because I don't have the book; I read it
- a few months ago) that there was a postwar official investigation of what
- happened at Coventry. Supposedly the Enigma decrypts were ambiguous
- as to the target. In military messages they tend to use coded names
- for geographical sites, as well as encrypting the messages; so even with
- a perfectly good and timely decrypt you may need additional information
- to know what the message means. In the middle of a war a lot of things
- can go wrong with the defense.
