Country	United Kingdom
Branch	Royal Navy

In March 1909, following a Royal Navy re-organisation, the Channel Fleet was absorbed by the Home Fleet. The ships in home waters, including the former Channel Fleet, then became the Home Fleet's First and Second Divisions.^[3] The former Home Fleet as it then stood became the Third and Fourth Divisions, which was actually a single formation under a vice-admiral.^[4] These new divisions was made up of an 8-12 ship battle squadron that included either dreadnought battleships or pre-dreadnought battleships.^[5] Within the Home Fleet there were two levels of availability - the ships of the 1st and 2nd Divisions which were fully operational, and those of the 3rd and 4th divisions that were either in reserve or partially manned.^[6]
