On 2 February 1771 the office of Senior Naval Lord was renamed to First Naval Lord. The first post holder was Vice-Admiral Augustus Hervey; he first served under First Lord of the Admiralty John Montagu, 4th Earl of Sandwich. In 1805, for the first time, specific functions were assigned to each of the 'Naval' Lords, who were described as 'Professional' Lords, leaving to the 'Civil' Lords the routine business of signing documents. On 2 May 1827 the Board of Admiralty once again ceased control of Naval Affairs and was replaced, until 1828, by a Lord High Admirals Council.
