Product Description

Review

"* 'Paul Gannon has revealed a previously untold story... Colossus tells of the heroic efforts of the inventors and mathematicians who received no recognition for decades... but Gannon sets the record straight.' Simon Singh, The Times * 'Masterly in its breadth and sweep... His account of wartime interception and encryption is deeply researched... I commend the book to both the professional and the general reader.' Spectator"

Guardian

read Gannon to feel the collective power of human minds harnessed to the cause of defending our freedom

colossal achievment 22 Jan 2006
By PJC
Format:Hardcover
Having waited so long to hear more of the latest 'secrets' from Bletchley Park one might ask what else could possibly not have already been put into print. This book concentrates on Colossus, exposing a 30 year old smoke screen using the Enigma story to deflect attention away from another of their successes, protecting modern secrets of GCHQ. The book is well-written, contains references to supporting texts and tells a story which will be hard to follow. The book contains an accurate technical picture of the colossal achievments, perhaps close to the limits necesssary to still make the 60 year old machine a national secret.

Format:Paperback
Perhaps it is easier for a telecommunications engineer turned computer software engineer to read but I found the book to be compelling. The book is not only technically impressive, it rings true in the portrayal of the characters and their relationships. I think only the Post Office Engineering Department, later the P.O. Telecomms Business could have produced Tom Flowers. I worked with many like him, engineers with the intuitive flair necessary to create complex systems who entered the business at the very bottom and rose through it by merit.

Excellent 11 May 2009
Format:Paperback
Paul Gannon's book on Colossus fills in a major blank in the story of Bletchley Park in WW2. It is sufficiently technical to give a picture of of Colossus and how it worked and includes a fascinating account of the strategic intelligence that it helped to provide. This book is an essential counterpart, equal in historical importance, to the numerous books on Enigma that have been published over the years.

Some problems with the paperback
There are at least two references saying "see the photographs" and "see the plates", but the (at least my) paperback contains no such plates. Read more

A very thorough and readable account of code breaking at Bletchley Park. Covers ground not previously published - so keen was the government to keep everything secret.

This book was initially of interest to me because of my fascination with Colossus itself but it turned out to be a different experience to that I anticipated !! Read more

reading as a non expert
Not a book for the first time reader of Ultra and Bletchley Park history. A somewhat confusing and poorly focused tale of Colossus and the codebreaking. Read more

Colossus - a disappointment
This book is far too long and tedious. He should have taken a leaf out of David Kahn's books (who he refers to). Read more

Colossus - a great read!
Couldn't put it down. You are lectured by some of the worlds greatest scientists, who undoubtably save the western world from the Nazis; it is written with humour and in excellent... Read more
