Good books on WWII codebreaking, enigma, etc?

Looking for more book recommendations here.

General topic I'm interested in is WWII codebreaking & espionage. A lot has been said about enigma, Turing, etc, so I guess those will do, but I've read a good amount in this area already. I've read a small amount about the US efforts to break the Japanese codes, including the reverse engineering of the Purple code machine, but I'd still be open to more in this theater. I'd really like to learn more about German vs Russian codebreaking and/or espionage, though these areas aren't as well covered.

Oh, and I'm very happy to get something that is a technical deep dive, so don't hold back those recommendations if you have them.

 

Hyperwar.

 

Try this.

Smith also wrote a book called "Station X" about Bletchley Park and code breaking. I've not read it so I can't give further details.

 

This, too.

 

Lou sent me a book ,that I recently passed on to a library, It was along this vein :

DONOVAN'S DEVILS: OSS Commandos Behind Enemy Lines--Europe, World War II - HamiltonBook.com.

Or this :

And you might try this:

The women codebreakers of World War II

 

The Enigma books are on Hyperwar.

 

Lots of good enigma suggestions. I've consumed a good amount on enigma over the years so hopefully looking for fresh non-enigma areas in which to dive. @OpanaPointer I appreciate the pointer, though I'm aware of the enigma books on HyperWar, (for obvious reasons).

Thanks all, keep them coming.

 

For you and the casual passer-by.

 

The Ultra manuals on hyperwar are first water docs.

 

Good call.
