Prince Frederick, Duke of York

The Prince Frederick, Duke of York and Albany (Frederick Augustus; 16 August 1763 – 5 January 1827), was the second eldest child and second son of King George III of the United Kingdom and a member of the House of Hanover. From the death of his father in 1820 until his own death in 1827, he was the heir presumptive to his elder brother, King George IV, both to the United Kingdom and the Kingdom of Hanover. Frederick was thrust into the British army at a very early age, appointed to high command at the age of 30, and commanded in a notoriously ineffectual campaign during the War of the First Coalition, which followed the French Revolution. 
 Frederick was mocked, perhaps unfairly, in the rhyme "The Grand Old Duke of York": 'The grand old Duke of York, He had ten thousand men. He marched them up to the top of the hill And he marched them down again. And when they were up, they were up. And when they were down, they were down. And when they were only halfway up, They were neither up nor down'

Later, as Commander-in-Chief during the Napoleonic Wars, he reorganised the British army, putting in place vital administrative and structural reforms.
 The Statute is situated on the Esplanade of Edinburgh Castle and a sculpture by Thomas Campbell, 1837.
Thomas Campbell (1 May 1790 – 4 February 1858) was a Scottish sculptor in the early 19th century. He has several important public works, most notably a statue of Sarah Siddons in Westminster Abbey. He also has several works in the National Gallery in London. He was heavily patronised by the British aristocracy, as evidenced by his works
