Georgetown University in Partial Fulfillment of the Requirements for the Degree of Master of Arts in Security Studies
THE BATTLE FOR INTELLIGENCE: HOW A NEW UNDERSTANDING OF INTELLIGENCE ILLUMINATES VICTORY AND DEFEAT IN WORLD WAR II A Thesis submitted to the Faculty of the Graduate School of Arts and Sciences of Georgetown University in partial fulfillment of the requirements for the degree of Master of Arts in Security Studies By Edward J. Piotrowicz III, B.A. Washington, DC April 15, 2011 Copyright 2011 by Edward J. Piotrowicz III All Rights Reserved ii THE BATTLE FOR INTELLIGENCE: HOW A NEW UNDERSTANDING OF INTELLIGENCE ILLUMINATES VICTORY AND DEFEAT IN WORLD WAR II Edward J. Piotrowicz III, B.A. Thesis Advisor: Jennifer E. Sims, PhD. ABSTRACT Does intelligence make a difference in war? Two World War II battles provide testing grounds for answering this question. Allied intelligence predicted enemy attacks at both Midway and Crete with uncanny accuracy, but the first battle ended in an Allied victory, while the second finished with crushing defeat. A new theory of intelligence called “Decision Advantage,”a illuminates how the success of intelligence helped facilitate victory at Midway and how its dysfunction contributed to the defeat at Crete. This view stands in contrast to that of some military and intelligence scholars who argue that intelligence has little impact on battle. This paper uses the battles of Midway and Crete to test the power of Sims‟s theory of intelligence. By the theory‟s standards, intelligence in the case of victory outperformed intelligence in the case of defeat, suggesting these cases uphold the explanatory power of the theory. Further research, however, could enhance the theory‟s prescriptive power. -

The Paris Apartment Is a Work of Fiction
READI NG GROUP GU I DE PhotosOfYou_TPTextFP Epilogue 2019-11-26 15:34:54 335 AUTHOR’S NOTE The Paris Apartment is a work of fiction. While a product of my imagination, the premises and characters I’ve chosen to create are inspired by real people and real events. The characters of Sophie Seymour and Estelle Allard were shaped by the experiences and courage of Virginia Hall, Pearl Witherington Cornioley, Christine Granville, Josephine Baker, Nancy Wake, and Andrée de Jongh. Their memoirs, interviews, and stories only give us an idea of how truly extraordinary each of these women was. Sophie’s work at Bletchley Park was based on the real men and women who worked tirelessly against time and almost im- possible odds to decode Nazi encryption devices. Most of us have heard of the Enigma cipher and the remarkable work by Alan Turing and his team to break that cipher. Told less often seems to be the story of Tommy Flowers and Bill Tutte, who, together with their teams, developed Colossus—the machine that was able to break the Lorenz cipher, known as Tunny at Bletchley. The Lorenz cipher was favoured by Hitler and used by High Command—and for good reason. It was a far more powerful than the Enigma and capable of exceedingly complex en- cryptions. Additionally, unlike the Enigma, it did not depend ParisApartment_TPtext1P Author’s Note 2020-10-01 21:13:57 395 396 AUTHOR’S NOTE on Morse code.

Notes to accompany four Alan Turing videos 1. General The recent (mid-November 2014) release of The Imitation Game movie has caused the com- prehensive Alan Hodges biography of Turing to be reprinted in a new edition [1]. This biog- raphy was the basis of the screenplay for the movie. A more recent biography, by Jack Copeland [2], containing some new items of information, appeared in 2012. A more techni- cal work [3], also by Jack Copeland but with contributed chapters from other people, appeared in 2004. 2. The Princeton Years 1936–38. Alan Turing spent the years from 1936–38 at Princeton University studying mathematical logic with Prof. Alonzo Church. During that time Church persuaded Turing to extend the Turing Machine ideas in the 1936 paper and to write the results up as a Princeton PhD. You can now obtaing a copy of that thesis very easily [4] and this published volume contains extra chapters by Andrew Appel and Solomon Feferman, setting Turing’s work in context. (Andrew Appel is currently Chair of the Computer Science Dept. at Princeton) 3. Cryptography and Bletchley park There are many texts available on cryptography in general and Bletchley Park in particu- lar. A good introductory text for the entire subject is “The Code Book” by Simon Singh [5] 3.1. Turing’s Enigma Problem There are now a large number of books about the deciphering of Enigma codes, both in Hut 6 and Hut 8. A general overview is given by “Station X” by Michael Smith [6] while a more detailed treatment, with several useful appendices, can be found in the book by Hugh Sebag-Montefiore [7]. -
Battle Management Language: History, Employment and NATO Technical Activities
Battle Management Language: History, Employment and NATO Technical Activities Mr. Kevin Galvin Quintec Mountbatten House, Basing View, Basingstoke Hampshire, RG21 4HJ UNITED KINGDOM [email protected] ABSTRACT This paper is one of a coordinated set prepared for a NATO Modelling and Simulation Group Lecture Series in Command and Control – Simulation Interoperability (C2SIM). This paper provides an introduction to the concept and historical use and employment of Battle Management Language as they have developed, and the technical activities that were started to achieve interoperability between digitised command and control and simulation systems. 1.0 INTRODUCTION This paper provides a background to the historical employment and implementation of Battle Management Languages (BML) and the challenges that face the military forces today as they deploy digitised C2 systems and have increasingly used simulation tools to both stimulate the training of commanders and their staffs at all echelons of command. The specific areas covered within this section include the following: • The current problem space. • Historical background to the development and employment of Battle Management Languages (BML) as technology evolved to communicate within military organisations. • The challenges that NATO and nations face in C2SIM interoperation. • Strategy and Policy Statements on interoperability between C2 and simulation systems. • NATO technical activities that have been instigated to examine C2Sim interoperation. 2.0 CURRENT PROBLEM SPACE “Linking sensors, decision makers and weapon systems so that information can be translated into synchronised and overwhelming military effect at optimum tempo” (Lt Gen Sir Robert Fulton, Deputy Chief of Defence Staff, 29th May 2002) Although General Fulton made that statement in 2002 at a time when the concept of network enabled operations was being formulated by the UK and within other nations, the requirement remains extant. -
Polish Mathematicians Finding Patterns in Enigma Messages
Fall 2006 Chris Christensen MAT/CSC 483 Machine Ciphers Polyalphabetic ciphers are good ways to destroy the usefulness of frequency analysis. Implementation can be a problem, however. The key to a polyalphabetic cipher specifies the order of the ciphers that will be used during encryption. Ideally there would be as many ciphers as there are letters in the plaintext message and the ordering of the ciphers would be random – an one-time pad. More commonly, some rotation among a small number of ciphers is prescribed. But, rotating among a small number of ciphers leads to a period, which a cryptanalyst can exploit. Rotating among a “large” number of ciphers might work, but that is hard to do by hand – there is a high probability of encryption errors. Maybe, a machine. During World War II, all the Allied and Axis countries used machine ciphers. The United States had SIGABA, Britain had TypeX, Japan had “Purple,” and Germany (and Italy) had Enigma. SIGABA http://en.wikipedia.org/wiki/SIGABA 1 A TypeX machine at Bletchley Park. 2 From the 1920s until the 1970s, cryptology was dominated by machine ciphers. What the machine ciphers typically did was provide a mechanical way to rotate among a large number of ciphers. The rotation was not random, but the large number of ciphers that were available could prevent depth from occurring within messages and (if the machines were used properly) among messages. We will examine Enigma, which was broken by Polish mathematicians in the 1930s and by the British during World War II. The Japanese Purple machine, which was used to transmit diplomatic messages, was broken by William Friedman’s cryptanalysts. -
Idle Motion's That Is All You Need to Know Education Pack
Idle Motion’s That is All You Need to Know Education Pack Idle Motion create highly visual theatre that places human stories at the heart of their work. Integrating creative and playful stagecraft with innovative video projection and beautiful physicality, their productions are humorous, evocative and sensitive pieces of theatre which leave a lasting impression on their audiences. From small beginnings, having met at school, they have grown rapidly as a company over the last six years, producing five shows that have toured extensively both nationally and internationally to critical acclaim. Collaborative relationships are at the centre of all that they do and they are proud to be an Associate Company of the New Diorama Theatre and the Oxford Playhouse. Idle Motion are a young company with big ideas and a huge passion for creating exciting, beautiful new work. That is All You Need to Know ‘That Is All You Need To Know’ is Idle Motion’s fifth show. We initially wanted to make a show based on the life of Alan Turing after we were told about him whilst researching chaos theory for our previous show ‘The Seagull Effect’. However once we started to research the incredible work he did during the Second World War at Bletchley Park and visited the site itself we soon realised that Bletchley Park was full of astounding stories and people. What stood out for us as most remarkable was that the thousands of people who worked there kept it all a secret throughout the war and for most of their lives. This was a story we wanted to tell. -

Where information has been derived from other sources, I confirm that this has been indicated in the thesis. ---------------------------------------------- 3 Abstract This thesis produces a critical and creative space for new forms of sound poetics. Through a reflective process combining theoretical research and poetic practice – performances, text-scores and installations – the thesis tests the contemporary terms of intermedial poetics and sound poetry, establishing a conceptual terminology for speech-matter. Beginning with a study of 1960s sound poet Henri Chopin and his relation to the tape machine, I argue that this technological mediation was based on a poetics of analogue sound hinged on bodily engagement. Social and physical properties of the tape machine contribute to a mode of practice that negotiates the body, machine, and effort. Exploring Michel Serres’s concept of parasitic noise and the relation of interference to lyric appeal, via the work of Denise Riley and Hannah Weiner, I understand sound poetics as a product of lyrically active noise. -
Guide to Secure Communications with the One-Time Pad Cipher
Cipher Machines & Cryptology Ed. 7.5 – Jun 11, 2018 © 2009 - 2018 D. Rijmenants http://users.telenet.be/d.rijmenants THE COMPLETE GUIDE TO SECURE COMMUNICATIONS WITH THE ONE TIME PAD CIPHER DIRK RIJMENANTS Abstract : This paper provides standard instructions on how to protect short text messages with one-time pad encryption. The encryption is performed with nothing more than a pencil and paper, but provides absolute message security. If properly applied, it is mathematically impossible for any eavesdropper to decrypt or break the message without the proper key.

Introduction One-time pad encryption is a basic yet solid method to protect short text messages. This paper explains how to use one-time pads, how to set up secure one-time pad communications and how to deal with its various security issues. Working with one-time pads is easy to learn. The system is transparent and you do not need a computer, special equipment or any knowledge about cryptographic techniques or mathematics. One-time pad encryption is an equation with two unknowns, which is mathematically unsolvable. The system therefore provides truly unbreakable encryption when properly used. It will never be possible to decipher one-time pad encrypted data without having the proper key, regardless any existing or future cryptanalytic attack or technology, infinite computational power or infinite time. -
