HMS Oracle was an Admiralty M-class destroyer which served in the Royal Navy during the First World War. The M class were an improvement on the previous L-class, capable of higher speed. The vessel was launched on 23 December 1915 and joined the Grand Fleet. Oracle spent much of the war involved in anti-submarine warfare. In August 1916, the destroyer rescued the crew of the light cruiser Nottingham, which had been sunk by a German submarine. In August 1917, the destroyer rammed and sank the submarine U-44. After the Armistice that marked the end of the First World War, the destroyer was transferred to Portsmouth. Initially, the destroyer was part of the local defence flotilla but soon Oracle was placed in reserve, decommissioned and, on 30 October 1921, sold to be broken up.
