Admiral of the Fleet John Rushworth Jellicoe, 1st Earl Jellicoe, GCB OM GCVO SGM (5 December 1859 – 20 November 1935) was a Royal Navy officer. He fought in the Egyptian war and the Boxer Rebellion and commanded the Grand Fleet at the Battle of Jutland in May 1916 during World War I. His handling of the fleet at that battle was controversial: he made no serious mistakes and the German High Seas Fleet retreated to port – at a time when defeat would have been catastrophic for Britain – but at the time the British public were disappointed that the Royal Navy had not won a victory on the scale of the Battle of Trafalgar. Jellicoe later served as First Sea Lord but was removed at the end of 1917 as a result of his pessimistic view, declaring that nothing could be done to defeat the U-boats. He also served as the Governor-General of New Zealand in the early 1920s.
