Présentation de l'éditeur

When the German cruiser Magdeburg ran aground off the Estonian coast in August 1914, little did the British Admiralty realise that what was onboard the ill fated vessel would hand them a decisive advantage in the battle for North Sea supremacy, and subsequently lead to the birth of the Government Communications Headquarters. Onboard the Magdeburg was a collection of clandestine codebooks and maps, containing coded squares, which offered invaluable clues as to the whereabouts of the German High Seas Fleet. Before long, the codebooks used by German warships, U Boats and naval zeppelins, and the ciphers used by the Germans to communicate with their naval attachés and embassies, had also fallen into the Admiralty s possession.
