The Bletchley Park memoir of Lord ASA Briggs will be one of the most important documents to be published in 2010. Lord Briggs has long been regarded as one of Britain's most important historians. He has never, however, written about his time at Bletchley Park.

The publication, which will coincide with Lord Briggs 90th birthday, is a meticulously researched account of life in Hut Six, written by a codebreaker who worked there for five years alongside Alan Turing and Gordon Welchman. In addition to discussing the progress of the Allies'code-breaking efforts and their impact on the war, Lord Briggs considers what the Germans knew about Bletchley and how they reacted to revelatory memoirs about the Enigma machine which were not published until the 1970s. Briggs himself did not tell his wife about his wartime career until the 1970s and his parents died without ever knowing their son's contribution to the wartime effort.

The book will be launched at Bletchley in May 2011, in the presence of other Hut 6 veterans and part of the proceeds will be donated to the fund to restore Hut 6 to its former glory.

Asa Briggs — distinguished historian, former chancellor of the Open University and vice-chancellor of Sussex — was there [at Bletchley Park] and is very much alive, as this gossipy and informative account shows.

The Spectator

There are marvellous illustrations in this book, marvellous anecdotes, such as the one about Hrothgar Habbakkuk, (which I am not going to tell you; read the book).... How fortunate we are that Lord Asa Briggs has so superlative a memory (and also that he kept a diary, which was absolutely forbidden!)'

Gwen Watkins, author of Cracking the Luftwaffe Codes

Without doubt, this is the most important book examining the work undertaken at Bletchley Park to be publish in recent times.

Britain at War magazine

Briggs is an engaging and amiable guide though the mysteries of wartime cryptography... a fascinating account of an outstanding young man and his time at a quite remarkable institution.

The Oldie Review

Lord ASA Briggs served at Bletchley Park as part of the team who were breaking down the Axis codes and ciphers. Brigg's new work is the first account of life at the park during the war. The book describes the daily routine and also describes the overall administration. As such it will undoubtedly become of great value to future researchers. The book not only provides a good read but should also become a future source of reference. Strongly recommended.


The memoir gives an interesting picture of the social life of Bletchley.

Military Historical Society

Lord Asa Briggs was made a Life Peer in 1976 as a most highly respected British Historian. Altogether (the book) can be described as a histiography of the place and as such will undoubtedly become of great value to future researchers. This is a book which not only provides a good read but should become a future source of reference... Strongly recommended.


An engrossing memoir of his own part in Hitler's downfall.

Military History Monthly

This lively account is a valuable addition to our understanding of its contribution to the Allied victory.

Times Higher Education

Its appeal is largely to those enthusiasts who collect and absorb all things related to BP.

Mathematics Today

Asa has not only had a long life, but also a remarkably rich and useful one, for which many people will be profoundly grateful. In these three volumes we can get some picture of what his life meant for him, his family and his many friends, and with it a comprehensive story of the times in which we live.

Western Morning News

Asa Briggs was a code-breaker working at Hut Six at Bletchley Park. While he is an author of great renown, until now he has not written about his time at Bletchley Park, indeed he did not tell his wife what he did during the war until the 1970s, and his parents died without ever knowing about the nature of his wartime service.

Thus, this is a historically important book, and enthusiasts of Bletchley Park will find much useful information here.

Destructive Music

With the ending of the Cold War, an increasing number of accounts of work at Bletchley Park and its out-stations has been published.
The author has produced a graphic human presentation of life at Bletchley Park and is one of the last surviving codebreakers of Hut 6. Most highly recommended.

Gordon Welchman Bletchley Park's Architect of Ultra Intelligence (Hardback)

'A magnificent biography which finally provides recognition to one of Bletchley's and Britain's lost heroes.' Michael Smith The Official Secrets Act and the passing of time have prevented the Bletchley Park story from being told by many of its key participants. Here at last is a book which allows some of them to speak for the first time. Gordon Welchman was one of the Parks most important figures. Like Turing, his pioneering work was fundamental to the success of Bletchley Park and helped pave the way for the birth of the digital age. Yet, his story is largely unknown to many. His book, The Hut…
