NAVAL ENIGMA : THE HISTORY OF HUT 8 : 1939 – 1945 by A P Mahon : edited by John Jackson. German Naval Enigma messages were the hardest to break at Bletchley Park during World War Two, due to the complicated way in which they were enciphered. A P Mahon, who joined Hut 8 in 1941 and led the Naval codebreaking team at Bletchley Park for the latter part of the war, gives a unique insight into the methods of discovering the secrets of the Kriegsmarine. These include the year-long battle to overcome the introduction of the four-wheel Enigma machine by the U-boat fleet in February 1942 involving the subsequent blackout of intelligence. The brilliant methods devised at Bletchley Park such as Alan Turing’s Banburismus system, overcoming the double-enciphered Officers-Only (Offizier) and the special U-Boat Short Signals, are all explained. Churchill made clear that the U-Boat war – the Battle of the Atlantic – was his greatest fear during World War Two. This is a unique insight into how that battle for vital intelligence was won, written by someone who was not only part of the team that helped win that struggle, but also who for part of the time, led it. There is a list of Naval keys, a Glossary, Biography and Index. 120 pages 210x295mm. 210x190mm.

THE SECRET WAR OF HUT 3
by John Jackson.

A new series of publications from the Archives of Bletchley Park. Bletchley Park was the “home” of the British code breaking activities in World War II. It was here that the German and Japanese radio signals were sent to be de-cyphered and then distributed to the Allied leaders and field commanders. The Archive represents a unique body of knowledge which now for the first time will be used to publish a series of monographs

9780854201143

At the end of World War II a history of the activities of Hut 3 was written by those who had actually worked in the Hut. The result was so sensitive that it was immediately given the highest security classification Top Secret – Ultra, it is only recently that this Official History has been declassified. This monograph is based on this publication.

Hut 3, was responsible for the processing of the signals once the code in which they had been transmitted, had been broken. They translated and annotated them and reported the contents to the Government departments and the commanders in the field. Hut 3, at its peak of activity had some 580 men and women working in it., which included 21 Americans. Hut 3 developed into an intelligence organisation the like of which had never been seen before. Their index systems, the technical expertise and research facilities were unique. This monograph explains how Hut 3 handled the signals they received, how their processing enhanced the value of the signals.

There are chapters on the Military, Air & Naval Sections, also the Duty Officers, Signals section, the Special Liaison Units, the German Book Room, Hitler’s Secret Weapons, the arrival of the Americans.

ULTRA’S ARCTIC WAR by John Jackson.

The Arctic convoys that took vital supplies at enormous risk to Russia during the Second World War did so within range of Germany’s Luftwaffe, surface ships and U-boats. These convoys were watched over by Bletchley Park codebreakers and intelligence officers, through decrypts of the German Enigma coding machine. In particular, these decrypts were closely involved in three of the key actions of the Arctic battles – the sinking of the battlecruiser Scharnhorst, the destruction of the battleship Tirpitz and the disastrous PQ17 convoy. This book examines the Ultra decodes, and for the first time lists the key details in these events in chronological order, detailing the role of the decrypts in a virtual minute-by-minute breakdown of how the signals were used in these key actions. 210x295mm.

THE OFFICIAL HISTORY OF BRITISH SIGNALS INTELLIGENCE 1914-1945 [Volume 1 (Part 1)] by Frank Birch : edited by John Jackson

This is the first time that this Official History has appeared in print. It was written in the period immediately after World War II when the author was the official “Sigint” historian in the United Kingdom. In World War I he was a member of the Room 40 team at the Admiralty and in WW.II. and was a senior member of staff at Bletchley Park. He gained a double first whilst at Cambridge University, after World War I he was a fellow of King’s College Cambridge. From 1937 he was advising the head of the Government Code & Cypher School (GC&CS). After World War II he was head of the historical section of GCHQ. He was allowed full access to all records and to ensure accuracy the original manuscript was reviewed by officers of G.C.H.Q. The History has only recently been declassified. It is the most authoritative account of how the British Signals Intelligence organisation was developed to became such a powerful instrument in defeating the Axis. The History begins with an analysis of the rôle and effectiveness of Signals Intelligence in World War I and the aftermath up to the early 1930s. With the increasing threat from Japan, Italy and Germany in the mid 1930s efforts were made to improve the Signals Intelligence at home and overseas. With the outbreak of war in 1939 the skeleton of what became the World War II organisation was in place. There were considerable problems that had to be overcome not least the competing requirements of the Fighting Services as well as the friction between the UK and overseas commands. What was eventually arrived at was a unique system that involved the Fighting Services, the Foreign Office and an array of civilians, many of whom had come from the academic foundations. The history includes numerous tables and diagrams that explain the development of the organisation and how it worked, also the inter-connections and the flow of information. For instance “The Chain of Control of Interception in 1941” shows how the “Y Organisation” Committee, which was headed by the Chief of the Secret Service, reported directly to the Chiefs of Staff. This volume includes First World War and after, the “Preparations for a New Emergency”- the pre WW.II organization. World War II – the Phoney War, the Norwegian & French Campaigns, plans in the event of invasion. The importance of “Y”. Military & Air Sigint at Bletchley, Organisations in the Mediterranean, Middle East & Far East. Naval Sigint in the UK. Traffic Analysis. Footnotes and sources. There is also an appreciation of Frank Birch. Whilst the G.C & C.S (Bletchley Park) activities, known now as G.C.H.Q, have been well documented, it was only part of the “SIGINT” operations. This history details and explains one of World War II’s greatest secrets.  210x295mm xli – 184 pages, includes extensive glossary and list of abbreviations, 32 pages of diagrams.
