It was established in 1917 and existed until 1964 when the department of the Admiralty was abolished, and the staff departments function continued within the Navy Department of the Ministry of Defence until 1971 when its functions became part of the new Naval Staff, Navy Department of the Ministry of Defence.
History of the British Army
The British Army during World War I could trace its origins to the increasing demands of imperial expansion together with inefficiencies highlighted during the Crimean War, which led to the Cardwell and Childers Reforms of the late 19th century. These gave the British Army its modern shape, and defined its regimental system. The Esher Report in 1904, recommended radical reform of the British Army, such as the creation of an Army Council, a General Staff and the abolition of the office of Commander in Chief of the Forces and the creation of a Chief of the General Staff. The Haldane Reforms in 1907, created an expeditionary force of seven divisions, it also reorganized the volunteers into a new Territorial Force of fourteen cavalry brigades and fourteen infantry divisions, and changed the old militia into the special reserve to reinforce the expeditionary force.
