Admiral of the Fleet Sir Henry Francis Oliver, GCB, KCMG, MVO (22 January 1865 – 15 October 1965) was a Royal Navy officer.

During the First World War, Oliver was sent to Antwerp where, with Belgian support, he blew up the engine rooms of 38 stranded German merchant vessels.

[3] He joined the armoured frigate Agincourt, flagship of the Second-in-Command of the Channel Squadron, in September 1880 and, having been promoted to midshipman on 21 January 1881, he transferred to the corvette Amethyst on the South America Station in March 1882.

He proposed a number of ideas for improving the organisation and training of the Navy's navigation branch, and was directed by Admiral Jacky Fisher, then the Second Sea Lord, to put them into effect.

[4] Appointed a Member of the Royal Victorian Order on 11 August 1905,[8] he went on to be commanding officer of the armoured cruiser Achilles in the Home Fleet in February 1907 and then became Naval Assistant to Admiral Fisher, now the First Sea Lord, in November 1908.

[9] Appointed a Companion of the Order of the Bath on 3 June 1913,[10] he was promoted to rear-admiral on 7 December 1913[11] and became Director of the Intelligence Division at the Admiralty later that month.

[2] In August 1914, just after the outbreak of the First World War, Oliver was sent to Antwerp, where, with Belgian support, he blew up the engine rooms of 38 stranded German merchant vessels.

[13] He became Second Sea Lord and Chief of Naval Personnel in September 1920 and in that capacity implemented the extensive expenditure cuts recommended by the Committee on National Expenditure chaired by Sir Eric Geddes in January 1922 and the large reductions in numbers of ships which were agreed under the terms of the Washington Naval Treaty in February 1922.
