HMS "Umpire" was a modified Admiralty destroyer which served with the Royal Navy. Launched in 1917, the ship operated with the Grand Fleet during World War I as an escort to a squadron of light cruiser and took part in the Second Battle of Heligoland Bight. After the Armistice, the vessel continued to serve and gained fame when its penant number, H10, was used as the name of the first house opened by what would become Veterans Aid after it had rescued the charity's founder from drowning. "Umpire" was sold to be broken up in 1930.
