-------

In 1909, following restructuring within the Admiralty, both the Mobilisation and War Divisions of the [Naval Intelligence Department](/wiki/Naval_Intelligence_Department_%28Royal_Navy%29 "Naval Intelligence Department (Royal Navy)") were brought together to create a separate Naval Mobilisation Department however this department existed only for a period of three years. In 1912 it was abolished and its functions became a component part of the [Admiralty War Staff](/wiki/Admiralty_War_Staff "Admiralty War Staff") sub staff divisions. In 1918 the Mobilisation Division of the Admiralty Naval Staff itself was dissolved and the Mobilisation Department was re\-stablished once again but not under the control of the Naval Staff instead it was responsible to the [Office of the Second Sea Lord](/wiki/Second_Sea_Lord "Second Sea Lord") this lasted until 1932 when it was replaced by a new [Department of the Director of Manning](/wiki/Department_of_the_Director_of_Manning "Department of the Director of Manning") that was itself a subsidiary department of the Second Sea Lord it continued to exist until 1964 when the Admiralty Department itself was abolished.
