December 1917 to November 1919 The selection of officers depicted was largely the suggestion of Sir Oswyn Murray, Secretary to the Admiralty, who proposed 20 admirals who had served at sea during the war. To his list were added the First Sea Lords in 1914 and in 1918, Prince Louis of Battenberg and Rosslyn Wemyss. Notable omissions include Admiral of the Fleet John Fisher, 1st Baron Fisher and Admiral of the Fleet Sir Henry Jackson, both of whom held the post of First Sea Lord during the war, Fisher from November 1914 to May 1915 and Jackson from May 1915 to December 1916. Fisher was omitted at his own request. Also left out were Dudley de Chair and Reginald Tupper, who commanded the 10th Cruiser Squadron in the Northern Patrol. The painting is held by the National Portrait Gallery but was not exhibited for several decades due to its poor condition. After restoration, it went back on display in May 2014 to commemorate the centenary of the beginning of the First World War.
