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.
2nd Infantry Division (United Kingdom)
The 2nd Infantry Division was a Regular Army infantry division of the British Army, with a long history. Its existence as a permanently embodied formation dated from 1809, when it was established by Lieutenant General Sir Arthur Wellesley (later to become the Duke of Wellington), as part of the Anglo-Portuguese Army, for service in the Peninsular War. (Prior to this, it was common for formations with the same number to be temporarily established for a single campaign and disbanded immediately afterwards; divisions remained a permanent part of the British Army's structure only after the Napoleonic Wars).
