The book "Marching Orders" by Bruce Lee tells the story of Magic intercepts of the Japanese military and diplomatic code and reviews the daily summaries read by Marshall and other US leaders in the context of what was happening in the war at that time The point of the book, c.1995, was that signals intelligence played a huge role, but unknown role, in influencing the actions of the U.S. and U.K. And that without understanding what the leaders knew there is a tendency to overestimate their skill / leadership ability.
