The Sea Lords were even without Naval Assistants and depended entirely on the help of a secretary provided by the civilian staff at the Admiralty.
In 1910 a new branch was formed termed the Mobilization and Movements Department under a Director.

This branch was a first step towards an Operations Division.
Under Mr.Churchill's regime at the Admiralty in 1911 a more regular Staff organization was introduced and a Chief of the War Staff, acting under the First Sea Lord, was appointed.

The organization introduced during his term of office is thus shown graphically: CHIEF OF STAFF | -- ---------------------------------------------------------- | | | Director of Director of Director of Operations Division.

Intelligence Division.

Mobilization Division.
In addition to other duties, the Mobilization Division was charged with the responsibility for the supply of fuel to the Fleet, from the Staff point of view.
In the organization introduced in 1911 the duties of the Chief of the Staff were defined as being of an advisory nature.
