British Naval Intelligence through the Twentieth Century

British Naval Intelligence through the Twentieth Century PDF Author: Andrew Boyd
Publisher: Seaforth Publishing
ISBN: 1526736608
Category : History
Languages : en
Pages : 757

Book Description
An 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.

Book Description
"The cast of characters that peopled Room 40, and its military equivalent, is as replete with brilliant academics and potty eccentrics as the more renowned codebreakers of Bletcheley Park in the Second World War. 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.

Book Description
Three 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.

Languages : en
Pages : 354

Book Description
"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."

Book Description
Admiral Sir Reginald 'Blinker' Hall, the Director of Naval Intelligence (DNI) for most of the First World War, described as 'a genius in his own sphere and brilliantly successful', was one of the outstanding if largely unrecognized naval leaders of that war.Naval intelligence's ability to read and analyse German naval and diplomatic signals on a daily basis was a significant factor in the allied victory. The Germans never realized that their codes had been broken. The revelation of the Zimmermann Telegram, surely one of the most exciting and significant events in the history of intelligence, astutely handled by Hall, was the catalyst that brought America into the war in April 1917. The German unrestricted submarine warfare campaign was then coming dangerously close to cutting Britain's supply routes. The effective interface between intelligence and operations, instituted by Hall and the anti-submarine chief, Admiral Duff, together with the introduction of convoy and with the Royal and US Navies working successfully together, resulted in the defeat of the U-boats.Hall's dynamic leadership, talent for lateral thinking and force of personality were essential to these successes. Above all he was endowed with the guile and ruthlessness which kept him one step ahead of a formidable and determined enemy and their widespread espionage and subversion operations.In Blinker Hall: The Man who Brought America into World War I, David Ramsay examines this fascinating man and his invaluable legacy.'Gripping ... This book is highly recommended, not only to intelligence buffs but to all with an interest in history and, indeed, in the workings of the international scene.' - The Naval Review

Dilly

Dilly PDF Author: Mavis Batey
Publisher: Biteback Publishing
ISBN: 1849542783
Category : History
Languages : en
Pages : 224

Book Description
The 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.

Plotting for Peace

Plotting for Peace PDF Author: Daniel Larsen
Publisher: Cambridge University Press
ISBN: 1108783643
Category : Political Science
Languages : en
Pages : 445

Book Description
With Britain by late 1916 facing the prospect of an economic crisis and increasingly dependent on the US, rival factions in Asquith's government battled over whether or not to seek a negotiated end to the First World War. In this riveting new account, Daniel Larsen tells the full story for the first time of how Asquith and his supporters secretly sought to end the war. He shows how they supported President Woodrow Wilson's efforts to convene a peace conference and how British intelligence, clandestinely breaking American codes, aimed to sabotage these peace efforts and aided Asquith's rivals. With Britain reading and decrypting all US diplomatic telegrams between Europe and Washington, these decrypts were used in a battle between the Treasury, which was terrified of looming financial catastrophe, and Lloyd George and the generals. This book's findings transform our understanding of British strategy and international diplomacy during the war.
