A few accounts from the individuals, who toiled night and day between 1914 and 1918, have survived and allow us to get a feel for what it would have been like inside Room 40 or MI1 (b) and to glimpse behind the mask of command and the veil of secrecy ..."--Back cover.

DOWNLOAD EBOOKThree years into the Great War, England's greatest asset is their intelligence network--field agents risking their lives to gather information, and codebreakers able to crack every German telegram. Margot De Wilde thrives in the environment of the secretive Room 40, where she spends her days deciphering intercepted messages. But when her world is turned upside down by an unexpected loss, for the first time in her life numbers aren't enough. Drake Elton returns wounded from the field, followed by an enemy who just won't give up. He's smitten quickly by the intelligent Margot, but how can he convince a girl who lives entirely in her mind that sometimes life's answers lie in the heart? Amid biological warfare, encrypted letters, and a German spy who wants to destroy not just them but others they love, Margot and Drake will have to work together to save themselves from the very secrets that brought them together.

DOWNLOAD EBOOK"While battalions hunkered down in the mud of western France, anti-aircraft guns took aim at zeppelins floating over the capital, and Atlantic convoys tried desperately to evade German U-boats, another, more secret battle was underway. Down gloomy Whitehall corridors a team of eccentric and pioneering codebreakers were fighting for information that would give them a decisive advantage over the enemy. The new technologies of wireless and telegraph were vital for governments and the military, but vulnerable to interception. Cracking the codes used to protect them quickly became a crucial part of the war effort, and London Room 40, led by the charismatic and cunning Blinker' Hall, was at the centre of this push for intelligence. Not content to wait for enemy communications to come to him, Hall was soon running agents in other countries, particularly in neutral USA where German saboteurs were intent on damaging the essential flow of munitions to Britain. The stories of Bletchley Park and the spies of the Second World War are well known, but it was Room 40 and their colleagues across the intelligence services that started it all. From the docks of New York City to shady Cairo hotels, this is the gripping and fast-paced story of spies, codebreakers and saboteurs."

DOWNLOAD EBOOKHow did the British codebreakers succeed in cracking the apparently unbreakable Enigma code during the Second World War? Was it their gifted amateurism? The brilliance of Alan Turing? The invention of the very first computers? Or the pioneering work of Polish cryptographers? It was all of the above. But there is one other crucial factor, which is much less well known. The same team had done it before. The truth is that many of those most closely involved in cracking the Enigma code - Alistair Denniston, Frank Birch, Dilly Knox - had wrestled with German naval codes for most of the First World War. By the end of the war they had been successfully cracking a new code every day, from their secret Room 40 at the Old Admiralty Building, in a London blacked out for Zeppelin Raids. The techniques they developed then, the ideas that they came to rely on, the people they came to trust, had been developed the hard way, under intense pressure and absolute secrecy during World War I. Before Enigma tells their story and explains how they managed to crack the supposedly indecipherable code. The book outlines the capture of the Magdeburg and the Hobart, discusses the use of cracked codes to bring German fleets to battle at Dogger Bank and Jutland, and focuses on individuals such as Winston Churchill and Admiral Sir Reginald 'Blinker' Hall and their importance in the development of a British naval code tradition.

DOWNLOAD EBOOKAn acclaimed military historian examines the vital role of British naval intelligence from the mid-nineteenth century to the end of the Cold War. In this comprehensive account, Andrew Boyd brings a critical new dimension to our understanding of British naval intelligence. From the capture of Napoleons signal codes to the satellite-based systems of the Cold War era, he provides a coherent and reliable overview while setting his subject in the larger context of the British state. It is a fascinating study of how naval needs and personalities shaped the British intelligence community that exists today. Boyd explains why and how intelligence was collected and assesses its real impact on policy and operations. Though he confirms that naval intelligence was critical to Britains victory in both World Wars, he significantly reappraises its role in each. He reveals that coverage of Germany before 1914 and of the three Axis powers in the interwar period was more comprehensive and effective than previously suggested; and while British power declined rapidly after 1945, the book shows how intelligence helped the Royal Navy to remain a significant global force for the rest of the twentieth century.

DOWNLOAD EBOOKThe highly eccentric Alfred Dillwyn Knox, known simply as 'Dilly', was one of the leading figures in the British codebreaking successes of the two world wars. During the first, he was the chief codebreaker in the Admiralty, breaking the German Navy's main flag code, before going on to crack the German Enigma ciphers during the Second World War at Bletchley Park. Here, he enjoyed the triumphant culmination of his life's work: a reconstruction of the Enigma machine used by the Abwehr, the German Secret Service. This kept the British fully aware of what the German commanders knew about Allied plans, allowing MI5 and MI6 to use captured German spies to feed false information back to the Nazi spymasters. Mavis Batey was one of 'Dilly's girls', the young female codebreakers who helped him to break the various Enigma ciphers. She was called upon to advise Kate Winslet, star of the film Enigma, on what it was like to be one of the few female codebreakers at Bletchley Park. This gripping new edition of Batey's critically acclaimed book reveals the vital part Dilly played in the deception operation that ensured the success of the D-Day landings, altering the course of the Second World War.
