This postcard from WW1 shows HMS Iron Duke and Admiral Jellicoe. Admiral of the fleet John Rushworth Jellicoe, 1st Earl of Jellicoe was a Royal Navy Officer. He fought in the Anglo-Egyptian War and the Boxer Rebellion and commanded the Grand Fleet at the Battle of Jutland in May 1916 during the First World War. His handling of the fleet at that battle was controversial. Jellicoe made no serious mistakes and the German High Seas Fleet retreated to port, at a time when defeat would have been catastrophic to Britain, but the public was disappointed that the Royal Navy had not won a more dramatic victory given that they outnumbered the enemy.
HMS Iron Duke served as the flagship of the Grand Fleet during the First World War, including at the Battle of Jutland. There, she inflicted serious damage on the German Battleship SMS König early in the main fleet action. In January 1917, she was relieved as fleet flagship. After the War, Iron Duke operated in the Mediterranean as the flagship of the Mediterranean Fleet. She participated in both the Allied Intervention in the Russian Civil War in the Black Sea and the Greco-Turkish War. She also assisted in the evacuation of refugees from Smyrna. In 1926, she was assigned to the Atlantic Fleet, where she served as a training ship.
