Again, the 'date started' function isn't working in GoodReads.
The American Magic is about the U.S. government's decipherment and employment of the Japanese 'Purple' code during World War II in particular and about the use and decipherment of Axis codes in general ('Enigma', 'Ultra' et cetera). Roughly chronological, the book begins with a very brief history of Anglo-American codebreaking starting with World War I, gives a sketchy overview of the principles involved, then gets into the historical account proper beginning with Pearl Harbor and ending with the Japanese surrender. The text is usually dry and matter of fact, but the authors does go out of his way to put in some justified digs against General Douglas McArthur. The book concludes with a discussion of the intelligence contribution to the debate on employing atomic weapons.
Father was an Army cryptanalyst attached to the Navy during the invasions of Sicily and Leyte.

Not as gripping as fiction😑I don’t think this is my type of book so maybe my review isn’t helpful but there was just a lot of archaic language for no reason which I don’t love (who uses whence??!!?) I think the book was pretty good just a tadddd hard to follow when you are not versed in all things WW2 and code breaking

A very good narrative on the background and the use of deciphered Japanese diplomatic codes (MAGIC) and IJN/IJA codes (Ultra) to the American advantages during WW2.
Although lacking of technical details, the author writes of Magic/Ultra intelligence at both strategic and tactical levels, plus his critical insights on the successful, as well as failed, use of them.
A good read for the topic of WW2 code breaking.
