Equine recipients of the Dickin Medal: There have been five equine recipients of the Dickin Medal since its creation in 1943.  The first three were British horses Regal, Olga, and Upstart, the Canadian Corps Cavalry horse Warrior and the American Sergeant Reckless.  The first three received their awards at a ceremony on 11 April 1947 at Hyde Park in recognition of the courage they exhibited during World War II.  These three were mounts used by members of the Metropolitan Police Service during official duties and to aid civilians during the Blitz and later bombings from September 1940 to late 1944.  Warrior served on the Western Front during World War I and was awarded an honorary posthumous medal in September 2014.  Another posthumous award was given in 2016 to Sergeant Reckless, a mare who served during the Korean War with the United States Marine Corps and was given the rank of staff sergeant.  Of the recipients, three were honoured for courage during active duty, one for remaining calm when his stable was bombed on two separate occasions and one to commemorate the actions of animals during the First World War.  The first three horses were selected primarily as a way to honour the entire mounted police force instead of singling out any particular deed.  Olga, Upstart and Regal are buried at the Metropolitan Police Mounted Training Establishment at Thames Ditton which also displays their medals in a museum.
