HMS Umpire was a modified Admiralty R-class destroyer which served with the Royal Navy. The Modified R class added attributes of the Yarrow Later M class to improve the capability of the ships to operate in bad weather. Launched on 9 June 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, after rescuing the charity's founder from drowning in 1924, the name of the first house opened by what would become Veterans Aid was named H10 after the destroyer's pennant number. Umpire was sold to be broken up in 1930.
