29-569: Completed at Kiel early in January 1918, she went to the Kiel School for shakedown and training until March, when she joined IV Flotilla . She was monitored continuously by British Naval Intelligence ( Room 40 ), on which her movement reports are based. All her operations took place in 1918. She departed 26 March on her first war patrol, operating in the Irish Sea and western entrance to

58-693: A battle; while the Imperial General Staff (Army) and Air Staff would give commanders general orders such as, "clear the enemy out of Africa" without telling them how to do it. Hence verbatim translations of naval decodes were sent by Hut 4 to the NID and nowhere else (except for some naval intelligence sent directly from Bletchley Park to Commanders-in-Chief in the Mediterranean). Hut 8 which decrypted Enigma messages for Hut 4 to translate and analyse had less information for Ultra as

87-521: A second voyage to European waters between March and August 1920, visiting Rosyth , Scotland, and Brest , France, and returning by way of the Azores with a captured German submarine in tow for the Panama Canal Zone . Back at Hampton Roads 18 October 1920, she returned to towing, salvage, and transport duty along the east coast. After conducting salvage operations on USS  S-5 through

116-716: The U-164 was supposed to come to the United States, but it was found in such atrocious shape that the U-111 was substituted. The other ships that were brought over to the United States were U-117 , U-140 , UB-88 , UB-148 , and UC-97 . All sailed to America under their own power except U-140 which was towed. These submarines were listed in U.S. Navy records as the Ex-German Submarine Expeditionary Force. By early September 1919

145-634: The 4th Naval District as a lightship . After towing targets and various craft along the U.S. East Coast , an occupation with salvage duty which was to be her major employment for many years, she sailed from New York on 8 August 1919 for Kirkwall , Orkney Islands , Scotland.

Falcon made

174-721: The Caribbean on both salvage and towing duty. In 1925, Falcon joined the Control Force for operations in the Panama Canal Zone , along the United States West Coast , and in the Hawaiian Islands . She returned to home waters in September, and began her part in the salvage operations on USS  S-51 under Lieutenant Henry Hartley in which she joined that fall and the next spring. After

203-532: The English Channel , sinking two steamers and returning to Kiel and 23 April. Her second patrol began 27 May, sailing from Heligoland Bight via Muckle Flugga to the western English Channel. She sank at least one confirmed steamer, and returned the same way, arriving 24 June. Her third patrol, between 25 August and 29 September, was via Fastnet and Scillies into the Irish Sea, where she was hampered by British A/S patrols and obtained no sinkings. She

232-702: The Reich War Flag . She arrived first at Portland, Maine on 18 April 1919, and then in New York City , New York on 19 April 1919 where U-111 docked at the Brooklyn Navy Yard . The U-111 , along with four other captured German submarines that were brought to the United States, were used to promote the sale of the Victory Liberty Loan . The U-111 can be seen in a short newsreel film after her arrival on YouTube. Originally

261-584: The U-111 had completed a head-to-head comparison test against the American submarine USS S-3 (SS-107) . It was found that, "The American boat is speedier, has a greater radius of action and is much more habitable than the German boats. Naval officers are of the opinion that the American submarine is the more seaworthy." A summary of the results of the tests from this article are shown in the following table. During

290-605: The Zimmermann Telegram played a role in bringing the United States into the War. It has described as the most significant intelligence triumph for Britain during World War I, and one of the first occasions on which a piece of signals intelligence influenced world events. Naval Ultra messages were handled differently from Army and Air Force Ultra because the Admiralty was an operational HQ and could give orders during

319-701: The submarine was raised through determined and ingenious efforts, it was Falcon who towed her to New York in July 1926, providing air pressure for the pontoons supporting the submarine, as well as her compartments. Acting as tender as well as salvage ship for submarines, Falcon accompanied them to fleet exercises in waters from Maine to the Panama Canal Zone , and conducted many operations to develop rescue techniques, as well as training divers . She stood by during deep submergence runs and other tests of new submarines, and played an important role in rescuing sailors from USS  Squalus in late May of 1939, and in

After this reorganisation, war planning and strategic matters were transferred to the newly created Naval Mobilisation Department and the NID reverted to the position it held prior to 1887—an intelligence collection and collation organisation. In 1912

406-449: The anchorage at Argentia , Newfoundland . One of her most important activities during the war was training divers, search, salvage, and rescue workers to man newer submarine rescue ships. Falcon was decommissioned at Boston , Massachusetts , on 18 June 1946. She was sold on 12 March 1947. Falcon portrayed a rescue ship in the 1937 movie Submarine D-1 , starring Pat O'Brien and George Brent . Footage of Falcon appears in

435-519: The beginning there were originally two divisions: (1) intelligence (Foreign) and (2) Mobilisation. In 1900 another division, War, was added to deal with issues of strategy and defence, and in 1902 a fourth division, Trade, was created for matters related to the protection of merchant shipping. The Trade Division was abolished in October 1909 in the wake of the Committee of Imperial Defence inquiry into

464-534: The coast of Cape Henry , Virginia, in 35 feet of water, well short of the 50 miles offshore where the tests were to take place. The stern of the submarine remained protruding above the water. Considered a navigation hazard, she was raised on 14 August 1922 by the USS Falcon , placed on pontoons, brought back to Norfolk Navy Yard , where she sank again in Number 3 dry dock before it could be pumped out. The submarine

493-642: The creation of his fictional spy, James Bond . The Geographical Section of the Naval Intelligence Division, Naval Staff, Admiralty, produced a series of Geographical Handbooks from 1917 to 1922 to provide information for the British Armed Forces .

522-537: The division was established as a component part of the new Admiralty War Staff organisation when that body was abolished in 1917 it continued as a division of the new Admiralty Naval Staff until 1964 when the Admiralty Department was abolished. During World War I the NID was responsible for the Royal Navy's highly successful cryptographic efforts, Room 40 . The interception and decoding of

551-587: The establishment of a unified Defence Intelligence Staff in 1964. It dealt with matters concerning British naval plans, with the collection of naval intelligence . It was also known as "Room 39" , after its room number at the Admiralty. The Foreign Intelligence Committee was established in 1882 and it evolved into the Naval Intelligence Department in 1887. The NID staff were originally responsible for fleet mobilisation and war plans as well as foreign intelligence collection; thus in

580-534: The feud between the First Sea Lord , Admiral Sir John Fisher and former Commander-in-Chief Channel Fleet , Admiral Lord Charles Beresford , when it was discovered that the captain heading the Trade Division had been supplying the latter with confidential information during the inquiry. In 1910, the NID was shorn of its responsibility for war planning and strategy when the outgoing Fisher created

609-432: The only maintenance performed was of a routine nature (cleaning, painting, etc.). She then made her way to Portsmouth , New Hampshire for decommissioning and destruction. The U-111' s final days on the seas were supposed to conclude in 1921. On 18 June 1921, while being towed from Portsmouth, New Hampshire, to be used as a target for aerial bombing by airplanes, she started to take on water. She sank about three miles off

696-569: The summer of 1921, she was assigned permanently to submarine salvage work, based at New London, Connecticut . On 14 August 1922 Falcon recovered the German U-boat U-111 off the Virginia coast, brought her to a dry dock at Norfolk Navy Yard, towed her back out to sea on 30 August 1922, and finally sank U-111 with a depth charge on 31 August 1922. She continued to perform occasional towing duty, and from time to time sailed to

725-769: The three service intelligence departments were amalgamated in the new Defence Intelligence Service at the Ministry of Defence .
