Which capital city shares its name with the horse ridden by the Duke of Wellington at the Battle of Waterloo?

Copenhagen is the capital and most populated city of Denmark. The Copenhagen metropolitan area has just over 2 million inhabitants. The city is situated on the eastern coast of the island of Zealand; another small portion of the city is located on Amager, and is separated from Malmö, Sweden, by the strait of Øresund.

Copenhagen (1808– 12 February 1836) was the Duke of Wellington's war horse, which he most famously rode at the Battle of Waterloo. Copenhagen was of mixed Thoroughbred and Arabian parentage, with his dame being sired by the Epsom Derby winner John Bull and his sire Meteor finishing second in the Derby. Copenhagen was foaled in 1808 and was named in honour of the British victory at the Second Battle of Copenhagen. Copenhagen did race in England for a short period, winning two races and finishing at least third in nine races out of his 12 career starts. Copenhagen was sent to Spain with Sir Charles Vane in 1813 and was then sold to the Duke of Wellington. Becoming his favourite, Copenhagen was the Duke’s mount in the Battle of Waterloo.
