Admiralty
It evolved from *Admiralty Navy War Council, (1909–1912) which in turn became the Admiralty War Staff, (1912–1917) before finally becoming the Admiralty Naval Staff in 1917. It was the former senior command, operational planning, policy and strategy department within the British Admiralty. 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.
Commander-in-chief of the British Armed Forces
By way of an example, this is still the case in Britain's second, and oldest remaining, where the Royal Navy's headquarters, main base, and dockyard for the North America and West Indies Station was established following independence of the United States of America. The colony had raised Militia and Volunteer forces since official settlement in 1612 (with a troop-of-horse added later), and a small force of regular infantry from 1701 to 1783. A large regular army garrison was built up after 1794, and the reserve forces faded away following the conclusion of the American War of 1812 as the local government lost interest in paying for their upkeep. From this point until the 1960s, Governors were almost exclusively senior officers of the Royal Artillery or Royal Engineers who were also military Commanders-in-Chief (and initially also Vice Admirals). Attempts to rekindle the militia without a Militia Act or funds from the colonial government were made throughout the century under the authorisation of the Governor and Commander-in-Chief, but none proved lasting. The colonial government was finally compelled to raise militia and volunteer forces (the Bermuda Militia Artillery and the Bermuda Volunteer Rifle Corps by act in the 1890s (the Bermuda Cadet Corps, Bermuda Volunteer Engineers, and Bermuda Militia Infantry were added at later dates), and these fell under the Governor and Commander-in-Chief, as well as under operational control of his junior, the Brigadier in charge of the Bermuda Command (or Bermuda Garrison, which included the regular as well as the part-time military (as opposed to naval) forces in the colony. Although the Royal Naval and the regular army establishments have been withdrawn from Bermuda, the Governor of Bermuda remains the Commander-in-Chief (though most recent office holders have not been career army officers) of the Royal Bermuda Regiment (a 1965 amalgam of the BMA and BVRC, which had both been re-organised in line with the Territorial Army after the First World War).
