British perspective of SIGINT development, planning, and political manuvering. Starts with the basic WWI/WWII SIGINT development and early technical challenges. Then moves more into overall system planning and all of the political manuvering between the principal players. Nice coverage of early equipment and techniques, with some perspective thrown in on all of the "interesting" personalities involved. These "personality conflicts" receive as much coverage as the early equipment and techniques. This is necessary, since all of the people involved really affected how the discipline developed.Overall an interesting read that covers early SIGINT development.
