“The Germans believed their Enigma ciphers were uncrackable. They continued to believe this throughout World War II.” This thrilling account of the Allied efforts to decode Axis messages—and keep the success of their efforts secret—describes the men and women behind the scenes, as well as the institutions they served, and the early computers devised for the purpose. Diagrams and period photographs add context and bring the participants’ exploits to life. A number of text boxes and sidebars adorn the pages, including “Who in History” boxes with information about figures who aided the code-breaking effort, and “History Detectives” boxes, with a focus on primary source material. Back matter contains a time line, glossary, additional resources, suggestions of other topics to research, and an index.
