Finally finished the book, Code Warriors

This book came out in 2016, and we picked it up cheap at a JeffCo Public Library Whale of a Book Sale. In short, the author, Stephen Budiansky, wrote a fascinating tome concerning the history of code breaking in the United States. If you want to know more about the background of the creation of the NSA, this is for you. It also covers many other federal agencies that are engaged in military intelligence and counter-intelligence.
