This book contains the U-boats situations and trends written by the staff of the Admiralty’s Operational Intelligence Centre during the Second World War. Based largely on communications intelligence, the U-boat situations and trends were designed to inform a small number of senior officers and high officials of the latest events and developments in the Allied war against the U-boats. The Battle of the Atlantic and the war against the U-boats was the longest and the most complex naval battle in history. In this huge conflict which sprawled across the oceans of the world the U-boats sank 2,828 Allied merchant ships while the Allies destroyed more than 780 German U-boats. These documents relate on a weekly, and in some cases a daily, basis exactly what the Allies knew concerning the activities of the U-boats during the Battle of the Atlantic.

The length, scale and intensity of the Battle of the Atlantic led the British and German navies to make substantial changes to their organisation, strategy and tactics. In this book, Dennis Haslop examines the pivotal lessons learned, and how these helped to determine the outcome of the Battle of the Atlantic Convoy War. He questions how well adapted the two organisations were to learn from the conflict, and how effective they were in identifying problems and producing remedies. Based on the in-depth analysis of British and German primary sources, this study provides an innovative basis against which to assess the German and British approach to changing warfare and provides important new insights into aspects of convoy warfare, in particular the virtually unknown subject of German 'Operational Research'.

In 1974 Frederick W. Winterbotham's book The Ultra Secret disclosed the Allied success in breaking the German high command ciphers in World War II, and a new form of history began—the study of intelligence and its impact on military operations and international politics. This guide documents and annotates over 800 sources that have appeared in the past 20 years. It examines and evaluates primary and secondary sources dealing with the role of ULTRA and MAGIC in the Pearl Harbor attack, the battles of the Atlantic, Coral Sea, and Midway, and the campaigns in the Mediterranean, Northwest Europe, the Middle East, and the Pacific, as well as in the realm of espionage and special operations. It also covers sources on the Sigint and cryptanalytic programs of the Axis and neutral powers.

Signals Intelligence (SIGINT) encompasses the various disciplines of wireless interception, cryptanalysis, communications intelligence, electronic intelligence, direction-finding, and traffic analysis. It has become the basis upon which all combat operations are undertaken. It is now widely recognized as an absolutely vital dimension to modern warfare and it has proved to be a vital component in the counter-intelligence war fought between the West and Soviet bloc intelligence agencies. The Historical Dictionary of Signals Intelligence covers the history of SIGINT through a chronology, an introductory essay, an appendix, and an extensive bibliography. The dictionary section has over 300 cross-referenced entries on key personnel, SIGINT technology, intelligence operations, and agencies, as well as the tradecraft and jargon. This book is an excellent access point for students, researchers, and anyone wanting to know more about Signals Intelligence.

From 1939 until 1942, Hitler's U-boats - his 'grey wolves' - threatened to accomplish what his air force had hitherto been unable to achieve: to starve Britain into submission. The struggle for control of the Atlantic was to become the longest, and one of the most bitterly fought campaigns of World War II. For Winston Churchill it was 'the only thing that ever really frightened me during the war'. During the course of five bloody and uncertain years, Britain and her Allies lost more than fifty thousand seamen and fifteen million tons of shipping protecting this lifeline. In 'The Battle of the Atlantic', Andrew Williams vividly describes this intense and strategically vital campaign in the fight for Allied victory. '...an excellent book.' Sunday Express

One of WWII's pivotal events was the capture of U-505 on June 4, 1944. The top secret seizure of this massive Type IX submarine provided the Allies with priceless information on German technology and innovation. After the war U-505 was transported to Chicago, where today 1,000,000 visitors a year pass through her at the Museum of Science and Industry. Hunt and Kill offers the first definitive study of U-505. The chapters cover her construction, crew and commanders, combat history, general Type IX operations, naval intelligence, the eight fatal German mistakes that doomed the boat, and her capture, transportation, and restoration for posterity. The contributors to this fascinating volume--a Who's Who of U-boat historians--include: Erich Topp (U-Boat Ace, commander of U-552); Eric Rust (Naval Officers Under Hitler); Timothy Mulligan (Neither Sharks Nor Wolves); Jak Mallman Showell (Hitler's U-boat Bases); Jordan Vause (Wolf); Lawrence Patterson (First U-boat Flotilla); Mark Wise (Enigma and the Battle of the Atlantic); Keith Gill (Curator, Museum of Science and Industry), and Theodore Savas (Silent Hunters; Nazi Millionaries).

Naval Warfare 1919–45 is a comprehensive history of the war at sea from the end of the Great War to the end of World War Two. Showing the bewildering nature and complexity of the war facing those charged with fighting it around the world, this book ranges far and wide: sweeping across all naval theatres and those powers performing major, as well as minor, roles within them. Armed with the latest material from an extensive set of sources, Malcolm H. Murfett has written an absorbing as well as a comprehensive reference work. He demonstrates that superior equipment and the best intelligence, ominous power and systematic planning, vast finance and suitable training are often simply not enough in themselves to guarantee the successful outcome of a particular encounter at sea. Sometimes the narrow difference between victory and defeat hinges on those infinite variables: the individual’s performance under acute pressure and sheer luck. Naval Warfare 1919–45 is an analytical and interpretive study which is an accessible and fascinating read both for students and for interested members of the general public.

This book presents an account of the life of naval commander Andrew Cunningham, the best-known and most celebrated British admiral of the Second World War. It supplements Cunningham's papers by Cabinet and Admiralty records, papers of his service contemporaries and of Churchill.
