Book Description
Excerpt from Manual for the Solution of Military Ciphers The history of war teems with occasions where the interception of dispatches and orders written in plain language has resulted in defeat and disaster for the force whose intentions thus became known at once to the enemy. For this reason, prudent generals have used cipher and code messages from time immemorial. The necessity for exact expression of ideas practically excludes the use of codes for military work although it is possible that a special tactical code might be useful for preparation of tactical orders. It is necessary therefore to fall back on ciphers for general military work if secrecy of communication is to be fairly well assured. It may as well be stated here that no practicable military cipher is mathematically indecipherable if intercepted; the most that can be expected is to delay for a longer or shorter time the deciphering of the message by the interceptor. The capture of messengers is no longer the only means available to the enemy for gaining information as to the plans of a commander. All radio messages sent out can be copied at hostile stations within radio range. If the enemy can get a fine wire within one hundred feet of a buzzer line or within thirty feet of a telegraph line, the message can be copied by induction. Messages passing over commercial telegraph lines, and even over military lines, can be copied by spies in the offices. On telegraph lines of a permanent nature it is possible to install high speed automatic sending and receiving machines and thus prevent surreptitious copying of messages, but nothing but a secure cipher will serve with other means of communication.

Book Description
"Success in dealing with unknown ciphers is measured by these four things in the order named: perseverance, careful methods of analysis, intuition, luck." So begins the first chapter of Colonel Parker Hitt's 1916 Manual for the Solution of Military Ciphers, a foundational text in the history of cryptology. An irrepressible innovator, Hitt possessed those qualities in abundance. His manual, cipher devices, and proactive mentorship of Army cryptology during World War I laid the groundwork for the modern American cryptologic system. Though he considered himself an infantryman, Hitt is best known as the "father of American military cryptology." In Parker Hitt: The Father of American Military Cryptology, Betsy Rohaly Smoot brings Hitt's legacy to life, chronicling his upbringing, multiple careers, ingenious mind, and independent spirit. In the 1910s, after a decade as an infantry officer, Hitt set his sights on aviation. Instead, he was drawn to the applied sciences, designing signal and machine-gun equipment while applying math to combat problems. Atypical for the time, Hitt championed women in the workplace. During World War I he suggested the Army employ American female telephone operators, while his wife, Genevieve Young Hitt, became the first woman to break ciphers for the United States government. His daughter, Mary Lue Hitt, carried on the family legacy as a "code girl" during World War II. Readers of Elizabeth Cobbs' The Hello Girls, Liza Mundy's Code Girls, and David Kahn's The Codebreakers will find in Parker Hitt's story an insightful profile of an American cryptologic hero and the early twentieth-century military. Drawing from a never-before-seen cache of Hitt's letters, photographs, and diaries, Smoot introduces readers to Hitt's life on the front lines, in classrooms and workshops, and at home.

Book Description
This manual presents the basic principles and techniques of cryptanalysts and their relation to cryptography. Cryptography concerns the various ways of protecting messages from being understood by anyone except those for whom the messages are intended. Cryptographers are the people who create and use codes and ciphers. Cryptanalytics is the art and science of solving unknown codes and ciphers. Cryptanalysts try to break the codes and ciphers created and used by cryptographers. This field manual covers the essentials of Cryptanalysis. Everything from medieval Arabic statistics to modern American comupting went into this Field Manual, thereby giving the reader a wide but deep view on the whole subject of cryptanalysis.
