NID25
Room 40, also known as 40 O.B. (old building; officially part of NID25), was the cryptanalysis section of the British Admiralty during the First World War. The group, which was formed in October 1914, began when Rear-Admiral Henry Oliver, the Director of Naval Intelligence, gave intercepts from the German radio station at Nauen, near Berlin, to Director of Naval Education Alfred Ewing, who constructed ciphers as a hobby. Ewing recruited civilians such as William Montgomery, a translator of theological works from German, and Nigel de Grey, a publisher. It was estimated that during the war Room 40 decrypted around 15,000 intercepted German communications from wireless and telegraph traffic. Most notably the section intercepted and decoded the Zimmermann Telegram, a secret diplomatic communication issued from the German Foreign Office in January 1917 that proposed a military alliance between Germany and Mexico. Its decoding has been described as the most significant intelli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stockton-on-Tees
Stockton-on-Tees is a market town in County Durham, England, with a population of 84,815 at the 2021 UK census. It gives its name to and is the largest settlement in the wider Borough of Stockton-on-Tees. It is part of Teesside and the Tees Valley, on the northern bank of the River Tees. The River Tees was straightened in the early 19th century, so that larger ships could access the town. The ports have since relocated closer to the North Sea, and ships are no longer able to sail from the sea to the town. This is due to the building of the Tees Barrage, which was installed to manage tidal flooding. The Stockton and Darlington Railway served the port during the early part of the Industrial Revolution. The railway was also the world's first permanent steam-powered passenger railway. History Etymology ''Stockton'' is an Anglo-Saxons, Anglo-Saxon place name with the common ending ''ton'', meaning ''farm'', or ''homestead''.

CS Alert (1890)
CS ''Alert'', or HMTS ''Alert'', was a cable layer, cable-laying ship that had a significant role in World War I. She was launched in 1871 for the Submarine Telegraph Company with the name ''The Lady Carmichael''. In 1890 the ship was acquired by the General Post Office (GPO) as part of the nationalisation of the Electrical telegraphy in the United Kingdom, British telegraph network. At the outbreak of World War I, ''Alert'' was immediately dispatched to cut German telegraph cables in the English Channel, seriously damaging Germany's ability to securely communicate with the rest of the world. ''Alert'' was taken out of service as a cable ship in 1915 but her cable-handling gear was retained for fitting on her replacement. After the war, she worked as a merchant ship under various names, finally being wrecked at Redcar under the name ''Norham'' in 1932. Construction and first cable work The ship was built by A.

Committee Of Imperial Defence
The Committee of Imperial Defence was an important ''ad hoc'' part of the Government of the United Kingdom and the British Empire from just after the Second Boer War until the start of the Second World War. It was responsible for research, and some co-ordination, on issues of military strategy. Typically, a temporary sub-committee would be set up to investigate and report at length on a specific topic. Many such sub-committees were engendered over the decades, on topics such as foreign espionage (a committee report in 1909 led to the founding of MI5 and MI6), food rationing, and aerial defence. It is possible to argue that the Committee of Imperial Defence was an important step in the development of national security coordination in the UK, and to see the current National Security Council as one of its descendants. History The committee was established in 1902 by Arthur Balfour, then British Prime Minister, following the recommendations of St John Brodrick and Lord Selborne, re ...
